New evidence from NASA indicates that the most likely places to find life beyond Earth are Jupiter’s moon Europa or Saturn’s moon Enceladus. They, like Earth, are both ocean worlds and in both therein are some of the key ingredients for life.

A wealth of hydrogen molecules in water plumes soaring from the ruptures in Enceladus’s icy surface, have been detected by the Cassini spacecraft. The vital chemical methane, could also be establishing itself in the ocean beneath the ice.

The elusive presence of a water plume erupting on the warmest part of Europa’s icy surface, which has a salty liquid ocean beneath it was shown by the Hubble Space Telescope. The ocean itself contains double the amount of water found in the oceans of Earth.

Europa could be the pick of the bunch for life-bearing within our own solar system outside of our homeworld. will launch In the 2020’s the Europa Clipper will be launched, and should arrive at Europa a few years later. It will be the first to explore an alien ocean and will also fly through the plume to collect data.

It will definitely be a first to discover Intergalactic Liver Cake – staple diet of Icewolves, and indeed most domestic canines Earth! The structure of the Liver Cake may differ slightly from much-loved Earthly treat, but the Europan version is just as mouthwatering and tasty to both lupine and canine alike 🙂 And what better time than Easter, the time of ressurection and new life, to discover tantsalising new life hopes on worlds not so very far from home?

 

 

 

 

 

 

Icewolf of course, did not go hunting any down without telling Clowie, the Pyrenean Mountain Dog…she would never dream of such indiscretion 😉 …. Never!

What If We “Got Shot” of the Moon? :   23 comments

 

No “Year In Review” From WordPress….So!

What If We “Got Shot” of the Moon?!!

‘The geological history of the moon and Earth are intimately tied together such that the Earth would be a dramatically different planet without the moon.’

It would? So what exactly would happen if we just got rid of it altogether and there was no moon? Which there probably wasn’t so far as many of us were concerned over Christmas! But say we blew it up?!! Blasted it completely out of the sky? After all do we actually need this shiny ball in the sky anyway?

The Birth of a New Ring World Earth Surprised smile

All those tiny fragments of blown up moon would be far too small to stick back together and create a new, if rather misshapen and little moon, which would have at least managed a near normal gravitational pull on Earth…important scientific detail….

A lovely ring would form around Earth consisting of little lumps of moon shrapnel …very, very tiny ones…very pretty but trouble is they wouldn’t be content with staying out there in space. Oh no, they would much rather make a regular and devastatingly determined habit of periodically hurtling out of their ring-world and slam-dunking into the Earth’s surface, bombarding us with meteorites that should otherwise never have thought of coming anywhere near us…oh dear! Moulton moon rain, cities destroyed, countries obliterated….

Moon formedImage NASA JPL-CaltechOn top of which, if we have blown the moon sky high all those particularly dangerous outer space meteorites that had previously hammered the moon’s surface would no longer have anything to prevent them making a bee-line for Earth, happily re-creating the Moon’s surface on the home-world! Great! Craters everywhere… Even more cities destroyed, countries obliterated….

 

 

 

 

 

 

 

Axial Tilt of Earth Eye rolling smile

In between moon rocks and meteorite bombardments from the rest of the cosmos, Earth, minus the moon’s gravitational pull would develop a wobble…it had a little one before but it was stabilised by the Moon, which also protected it from the gravitational pull of the other planets…now it would have a huge wobble, and be pulled one way by Mars and another way by Jupiter – our planetary neighbours. Consequently with no moon to slow Earth’s orbit down we would be flying merrily around the sun in a wildly unhinged and erratic orbit…. shortening Earth’s day from 24 hours to only 8 – 10 hours.

Catastrophic seasonal changes Disappointed smile

moon_asexuality.orgOn top of which whilst currently we are worrying about global warming and climate change….or at least those of us with a scrap of common sense are, with the moon gone these problems will seem trivial….of course to the uneducated or just plain stupid they already are, but you “aint seen nothing yet!!”

Earth would be a very, very different place. As it would now be rotating so much faster, 160-200 km winds would be zooming across Earth’s surface.

 

 

 

 

 

 

 

With Earth’s now unstable axial tilt, we would see dramatic environmental changes over the course of thousands-millions of years – the loss of our conventional seasons and radical modifications in temperature would cause wide-ranging consequences for the growth of plant life and crops. This in turn would create some major headaches and very thorny problems for producing food for the billions of people dwelling on Earth. The animal world would have to adapt pretty quickly to a much shorter life pattern in terms of mating, migration and hibernation.

maxresdefault

Moreover, the changing temperatures would lead to the loss of Earth’s N and S Poles. To an extent this is already happening but in such circumstances melting ice would have a hugely dramatic effect on the oceans which would rise to a point where they change the all the world’s coastlines.

Life on Earth both in countries and in cities would have no choice but to adapt pretty drastically in order to survive or disappear into extinction.

 

Tidal Chaos Confused smile

With no moon to affect the tides, which show a configuration related to the lunar phase cycle, Earth’s oceans would become very tranquil and still. Solar tides would have a very small effect; about half that of the Moon, so there would be the odd wave or two. (Assuming we hadn’t blown the Sun up as well 😉 ) Tides were also important in life’s early stages of evolution so this would be terrible news for sea life which would rapidly become extinct. Barely-there tides do not mix oceans which therefore do not circulate nutrients required for sea-life’s survival…so fishermen would quickly go out of business and no –one would be microwaving their “Fisherman’s Pies” ever again!

Full Wolf Moon–January 5th 2015   21 comments

howling-at-the-moon-hippotipus-dff_080723 

 

119453360_640Full Wolf Moon Registration Banner

The Wolf Moon rising at 17:15 – 5th January 2015, for the one and only time this New year, is the first full moon following the winter solstice. In a little touch of moon wolf magic the 2015 Wolf Moon also coincides with the arrival of Earth at the closest point to the sun that it is possible for it to reach in its orbit (perihelion).

Earth stands just 91.4 million miles from the sun, at this point and consequently the full moon burns brighter than even the Europan Ice Wolves on their frozen world of ice…

The Wolf Moon has also come to mark the start of a long year of stargazing.

January is the only month of the year when Mercury, Venus, Mars, Jupiter and Saturn can be viewed without a telescope. And if you look very carefully in the magic of the moonlight and maybe wish upon a star you may see the flash of the moon wolves of icy Europa…moon of Jupiter….if you’re really quiet you may here the call of the wolf-song across the star-ways of time and space…the moon-song of the star-born of Europa….

Happy New Year 2015 from the Ice-wolves of Europa!

You Won’t See This In Sochi! Final Tails Of 2014 Galactic Olympics   51 comments

You Won’t See This in Sochi!!

The Final Tails of Valhalla Basin Winter Galactic Olympics

Running alongside the renowned cosmic Galactic Winter Olympics are the equally well renowned Space Galactic Dog Trials. The enthusiastic and well-informed interstellar tourist will undoubtedly have ensured their place at the Opening Ceremony on Io –the fiery, sulphuric neighbour of Europa’s Icewolves glittering world of ice; home to the magnificent and mysterious Firewolves of Io, creatures as wild and fiery as the stunning sulphur volcanoes erupting in explosive abandon throughout their moon-world, their presence at the trials opening ceremony guaranteed a truly alien dimension to this un-missable cosmic K9 event.

Entertainment abounds at this time of the Galactic Winter Olympics both for the 2-legged thrill seeker and also for the 4-legged K9 variety:

MercuryMercury Tandoori Chicken Tracking Trials

Great for Galactic Olympic tourists who enjoy basking in a slightly warmer environment than is offered by the outer planets of the galaxy where the Winter Olympics are taking place.

  1. K9 Cross-country Tandoori Chicken Tracking – across the Van Eyck Formation (Mountain ranges on Mercury).
  2. Morning jogging –lose 50-60lbs, watch the awesome double sunrises and relax in the evenings and lay down to get great views of the other planets.
  3. Mercury’s Polar Ice Caps which offer wonderfully strange and bizarre views to thrill and tantalise the senses of even the most hardened galactic tourist.
  4. Roast marsh mallows whenever you like without worrying about nasty gases polluting the environment.

Warning!

Don’t forget the sunglasses and shorts!! And definitely don’t forget the sunscreen! Factor 1000000!

Arrive here at light speed – about 2 minutes. Arrive by snail transport – 5 months – from Earth/Sochi. But no need to worry about sunburn – sun blocked out by clouds.

  1. 1. Lose weight in the natural outdoor saunas (460 degrees – hottest in Solar System – 40,000,00m closer to the sun).
  2. 2. Shower in the rain afterwards or for the more adventurous enjoy a Venutian mud bath.
  3. 3. Visit the mind bogglingly huge Maxwell Montes volcanoes – a Venutian star attraction for any galactic tourist, and pop down to Maat Mons’s frozen lava rivers.
  4. 4. Hi speed cooking – dinner will be cooked in less than one minute so no need to pack the microwave.

Warning!

Don’t forget the 100000 bottles of sunscreen factor and the 100+ towels! You and your equipment will erode very quickly in Venus’s yellow skied, highly toxic, corrosive atmosphere 🙂 So cover everything up well and check it’s safety certified and insured!

As any self-respecting Galactic Olympic enthusiast will be very happily well aware, the 2014 Valhalla Basin Galactic Olympics is now in full swing. Meteoritic medals are being won, and a variety of arms and legs are in danger of being broken, along with a smattering of other appendages as brave and heroic Galactic athletes take breath-taking risks hurtling down icy bob sleigh runs and mind-blowing ski slopes, snowboarding at break-neck speeds on tiny little “tea trays.” 😉 and spinning gracefully around zero-gravity ice rinks to name but a few.

Naturally the hard-core Galactic Olympic enthusiast will have been overcome by an all-consuming desire to participate in these exciting, heart-stopping winter sports events…so where can you show off your finely honed skills?!! And what’s on offer for you excitable Galactic Olympian wannabes?!!! Look no further for all you need to know about the Galactic Winter Olympic Events and Locations!

Callisto_Credit_nssdc.gsfc.nasa.govCallsito [Jupiter’s Moon] – Valhalla Basin

Ice Events (Figure Skating, Ice Dancing and Short Track Speed Skating)

  • Ice skating on the frosty bright-floored 360 km wide central basin.
  • Snowboarding and hi-speed skating around the 8+ concentric frozen mountainous ridges

Asgard Crater

Nordic Events (X-country skiing and Ski Jumping) Snowboarding events

  • X-country skiing around the multi ring structure
  • Snowboarding jumps and ski jumping from the centrally-situated domed Doh impact crater dominating Asgard.
  • The uneven terrain and tenuous CO2 atmosphere allows athletes to pull off some very impressive stunts during these events!

Europa [Jupiter’s Moon]:

europa_solarsystem.nasa.gov_Credit_NASA_JPL-Caltech europa1_Credit apod.nasa.govSkiing Events (Alpine and Freestyle) Nordic Event (Ski Jumping)

It should also be noted that skiing on Europa will involve:

  • Slower acceleration when skiing downhill (Gravity compared to Earth’s, Mars <1/3, Europa <1/7, Moon 1/6)
  • Bigger skis maybe necessary to help with turning
  • Ski jumping will require longer ramps as there is less acceleration – no air resistance. No air at all in fact!
  • Crashes and falls will not lead to lost marks as you will be dead!!!

Snowboarding:

  • Naturally occurring ½ pipes stretching for 100s miles (caused by gravitational tides changing the shape of the surface)
  • Tenuous atmosphere means no aerodynamic drag so snowboarders can stand tall going downhill, not the usual crouch. Steering is also easier.

Ice Event: Curling:

  • Europa is ideal for this activity having the smoothest surface in the solar system.

WARNING!!

Radiation is very harsh on Europa; the result of dangerous belts of radiation from Jupiter’s planetary magnetosphere – the largest and most powerful in the Solar System. So don’t forget your radiation suit and iodine tablets! And remember! Snowboarding/skiing in lead lined radiation suits will provide an excellent muscle workout!

Martian Ice Caps:

Skiing Events and Ice Events: Bob sledding, Ice Hockey

                             Mars ice cap_rutgersprep.orgMars_Chasma Boreale_N Polar Ice Cap_themis.asu.edu

WARNING!!

Don’t forget your scarf! And remember Mar’s atmosphere is very thin so you don’t get any protection from the Sun’s energy bursts. You also don’t get to enjoy snowball fights on the Ice Caps – the atmosphere’s too weak and cold meaning snowballs can’t /hold together like they’re supposed to. And no! You can’t throw the ice; it’s very, very bad form!

A Martian Ice Cap sounds like the ideal skating rink but it is actually not that great for skating being cold and dark and snowing carbon dioxide. In fact it is probably better suited to Roller Skating!

Tethys [Saturn’s Moon] : Ithaca Chasm and Odysseus Crater:

Tethys_JPL_map_Credit celestialmotherlode.nettethys-ithaca-chasmaAll Nordic Events: X-country skiing and Biathlon

  • Great valley named after Greek Island Ithaca and the country ruled by Odysseus in mythology.
  • 100 km wide, 3-5 km deep and 2000km long running ¾ of the way round the circumference making it one of the longest valleys in the Solar System.
  • Runs approximately concentric with the massive Odysseus Crater, located on the opposite side of Tethys
  • Giant Impact Crater – Odysseus 400 km diameter is almost 2/5 of the whole of Tethys.

WARNING!!

Cold, airless and heavily cratered world! Surface temperature -187 degrees, very icy, and very reflective. Don’t forget the woolly scarf, thermal undies and snow/sun-glasses!!

Triton [Neptune’s Moon]:

triton-cryovolcanos_Credit wanderingspace.netNordic Combi: Ski Jumping, X-Country Skiing, and Snowboarding

  • Relatively flat, sparsely cratered surface with extensive ridges, troughs, furrows, plateaus and valleys, and icy, smooth volcanic plains
    • Perfect for X-Country Skiing.
  • Highly reflective polar caps consisting of nitrogen and methane.
    • A great spot to catch Galactic Olympic Ski Jumping!
  • Mounds and round pits formed by icy lava flows; long double ridges of ice with troughs in the middle.
    • Particularly well suited to Cosmic Snowboarding events.

WARNING!!

To aid launch jumping Nitrogen-gas heated shoes for generating explosive puffs of gas when feet touch the ground, are strongly recommended for all competitors.

Crashing is not recommended!!

Valhalla Basin (Galactic Winter Olympics)–Let The Games Begin!!   20 comments

 

2014 Galactic Winter Olympics, officially the XXII Galactic Olympic Winter Games (22nd Galactic Winter Olympic Games)

Held at Valhalla Basin, Callisto (Jovian System).

2014 Valhalla Basin (Galactic Winter Olympics)

The main venue of the Galactic Winter Olympics, Valhalla Basin, (Hall of Odin or Hall of the Slain in Norse Mythology), is also a crater produced by an impacting meteor. It sports the largest multi-ring impact crater on both Callisto (Galilean moon of Jupiter, sister world of Europa) and within the Solar System.

Part of an extensive system in the Valhalla region Valhalla’s bright-floored central basin stretches across a diameter spanning 360 km. It is surrounded by at least eight concentric mountainous ridges, which resemble frozen rings of ghostlike ripples extending as far as 1,500 km from the basin’s central point.

2014 Winter Olympics – Chelyabinsk Meteor Anniversary

2014-winter-olympics-logoThe 2014 Winter Olympics, officially the XXII Olympic Winter Games (22nd Winter Olympic Games), are set to take place from 7 to 23 February 2014, in Sochi, Russia.                 clip_image001clip_image001[1]

Chelyabinsk meteor Chelyabinsk meteor 2The Chelyabinsk meteor was a Near-Earth asteroid that entered Earth’s atmosphere over Russia on 15 February 2013 exploding in an air burst about 40 km above Korkino, south of central Chelyabinsk Oblast. The explosion created a bright flash, churning out a sizeable quantity of small meteorite fragments and a formidable shock wave.

Lake Chebarkul The meteorite fragments fell in and near to Lake Chebarkul with the largest extracted from the bed of the lake on 16 October 2013. Despite its 654 kg (1,442 lbs.) mass tipping and breaking the scales it was weighed on, it proved very fragile and shattered into three distinct pieces. In the aftermath of the Chelyabinsk meteor event an unofficial market swiftly arose for meteorite fragments.

The anniversary of the Chelyabinsk meteor event will be in Sochi, Russia on 15 February 2014. A total of seven gold medals are available to be won during the anniversary day’s medal events and each will contain fragments of the Chelyabinsk meteorite.

Callisto (2014 Valhalla Basin Galactic Winter Olympics)

callisto2In a very interesting to note lol that by some strange cosmic coincidence the 2014 Valhalla Basin Galactic Winter Olympics will be held on Jupiter’s extremely ancient Galilean moon Callisto, the most heavily cratered moon in the Solar System.

Callisto’s impact-battered surface features multi-ring structures, variously shaped impact craters, and chains of craters (catenae). Probably due to the icy nature of its surface Callisto lacks any large mountains. The water that has spread over the surface forming bright rays and rings around the crater is a result of the meteorite impacts puncturing holes in Callisto’s crust.

It is now believed that beneath Callisto’s crust may lie a salty, subsurface ocean of liquid water around 50–200 km deep indicated by studies of the magnetic fields around Jupiter and its moons. This leaves open the option that there could be extra-terrestrial microbial life on Callisto, though conditions are thought to be less conducive to life than on neighbouring Jovian moon Europa.

Callisto in Olympian Mythology

Mount-olympusZeus and CallistoZeus-greek-mythology-god-of-the-godsCallisto is named after one of Zeus – god of the Olympics and Supreme Ruler of Mt Olympus’s many lovers, in Greek mythology. It is said that Callisto herself was a nymph who was associated with the goddess of the hunt, Artemis.

Zeus was held in exceptionally high esteem and power by the Ancient Greeks and once every four years the Olympians held a festival including games to honour their god. Today nations still meet for the Olympic Games but not to honour Zeus, rather the ability of the athletes themselves are considered and rewarded.

 

Valhalla Basin (2014 Galactic Winter Olympics)

Valhalla Basin_Credit_WikipediaValhalla Basin_Credit NASA_JPLIn another wildly unlikely cosmic coincidence, the main venue of the Galactic Winter Olympics, Valhalla Basin, is also a crater produced by an impacting meteor. (Not the same one as Russia’s! Don’t be silly!) Furthermore it is not only the largest multi-ring impact crater on Callisto but also in the Solar System.

Discovered by the Voyager probes in 1979–80 it is located slightly to the north of the equator on Callisto’s Jupiter-facing hemisphere. Part of an extensive system in the

Valhalla region Valhalla’s bright-floored central basin stretches across a diameter spanning 360 km. It is surrounded by at least eight concentric mountainous ridges, which resemble frozen rings of ‘ghostlike ripples’ extending as far as 1,500 km from the basin’s central point.

Valhalla in Mythology

ValhallaOdinThis huge impact crater is named after Valhalla, Odin’s great hall in Norse mythology.  

                                                                         

Valhalla_was_in_Asgard_Home_of_the_fallen_VikingsValhalla, Hall of the Slain, in Norse mythology is the most beautiful of Asgard’s many great halls. It was here with Odin that the W Door Valhalla Guarded by a Wolfheroes who had been slain in battle – the Einherjar, feasted nightly on the meat of the boar Schrimnir and from the goat Heldrun, mead, whilst preparing for the up and coming battle of Ragnarok. Eight hundred warriors marching shoulder to shoulder will emerge from each one of Valhalla’s five hundred and forty doors when this time comes.

Vast and daunting Valhalla was said to have spears for rafters and golden shields providing roofing thatch, along with a fine array of breast plates, scattered around the Hall.

The western door of Valhalla is guarded by a wolf and hovering high above the door an eagle. Outside the front of the hall is Glasir, a golden tree and on the roof of Valhalla, the green leaves of another tree known as Læraðr – happily munched through by the goat Heldrun and the stag Eikþyrnir.

Asgard Crater Region– Callisto

To the west of Valhalla is another large multi-ring basin—Asgard Crater; the second largest multi-ring structure (impact crater) on Jupiter’s moon Callisto. The crater is named after Asgard, the realm of the gods in Norse mythology,

Asgard in Norse Mythology – Olympic Links

Bifrost and ValhallaThe Norse equivalent to Mount Olympus in Greek mythology, Asgard was the home and stronghold of the Norse gods. Set in the skies the only way to reach it was to cross Bifrost – the rainbow bridge.

Valhalla, the dwelling of Odin was the grandest and most magnificent of the many gold and silver halls to be found in Asgard. Norse mythology stated that Asgard would be destroyed at Ragnarok -"Doom of the powers (gods)," also known as “Gotterdammerung” which in Norse mythology means “the end of the cosmos.” A huge final battle would be fought and the world enveloped in flames; the gods defeated by giants and demons. But a number of the gods will survive, or will be reborn and out of the sea a green and fertile world will emerge.
