Raining Glass on Exotic Blue Marble Planet   14 comments

 

Exotic Blue-Marble Planet Raining Glass…Sideways!

Exo-Planet HD 189733b

We all know exotic alien planets can be very strange and bizarre, and turbulent blue marble exo-planet HD 189733b in the constellation of Vulpecula (The Fox) is no exception. In fact this alien world is a shining example of wild and exotic alienness. Scoring a first for humanity (and Europan Ice Artist impression of HD 189733b_Image credits: NASA, ESA, M. KornmesserWolves if you happen to be lucky enough to be part of the Pack) those clever NASA and ESA astronomer types with a smidgling of help from the Hubble Space Telescope have figured out the real planetary colours of an alien world circumnavigating another sun; something it does this in 2.2 Earth days tucking in very close and cosy with its parent star (sun).

Although at first glance, and this would have to be a very close up glance, this deep azure blue world, a giant gas planet known as a “hot Jupiter” bears a remarkable similarity to the heart-warming blue colour of Earth as seen when floating just above it in a cosmic deck chair whilst sipping an intrepid tequila in intergalactic space and admiring the view. Smile

However, before you all go rushing off to dust off those aeon old telescopes lying forgotten in the attics and lofts of the home world, don’t! Not a good idea at all. Leave them right where they are…gathering very un-alien like Earth dust! HD 189733b is one of the closest exo-planet’s to Earth but it still lies 63 light years (630 trillion kilometres) from Earth and despite the fact that it shares pretty much the same size and mass stat’s as the Europa’s Ice wolves mother world, Jupiter, and still shines with that beautiful star-blue glow, and even has awesome sunsets, you won’t be able to see it!! No… not even a little blue dot so just take a nice deep breath of Earth air and calm down!

Colour is where the similarity between this exotic exo-planet and Earth end, swallowed hungrily by its dramatically unstable and exotic, atmosphere where it rains glass sideways (drops of molten magnesium silicate particles) in a furious frenzy of hurricane-force winds hitting a ferocious, hyperactive 7000 kilometres-per-hour (4,350 mile per hour). With a searing atmospheric temperature of 1000+ degrees Celsius (1,832 degrees Fahrenheit/1000 degrees C day side, 1,200 degrees F/650 degrees C night side – tidally locked so one side always faces its sun) atmospheric water exists in the form of steam, intermingled with vapour mists and fierce, blazing flares. 1,000 tons of its atmosphere is blown away with each passing second by its sun’s (star’s) intermittent solar surges.

Blue Planet_Credit:GoogleAnd why is HD 189733b a deep and shiny azure blue colour? I hear you ask…albeit very quietly in a “don’t tell Wolfie we asked or we’ll be here all night” kind of tone. The sideways-raining glass (magnesium silicates) in its hyperactive atmosphere, scatter blue light very effectively to create this effect. Earth shines bold and blue due to the blue colours in the sunlight scattering in the atmosphere. Yes, the sun is still there to achieve this very important end even if you can’t mostly see it through all that lovely grey cloud cover. Cold, distant Neptune is also a blue planet, but for the entirely different reason that its air has copious levels of methane gracing it. This decidedly non-breathable Neptunian methane does a pretty good job of absorbing red light blotting it out altogether to human eyesight so that Earth dwellers beady little eyes will only see the blue light reflecting back to them and therefore Neptune is blue. This is a very therapeutic and relaxing colour for the average Earth dweller to cast their beady little eyeballs on according to the therapists.

Exo-planet temperature map data revealed by NASA’s Spitzer Space Telescope In 2007 allowed scientists the opportunity to chart the bizarre weather environment of the exotic, alien world of exo-planet HD 189733b. It was concluded that there are roughly 500 degrees Fahrenheit (260 degrees Celsius), differences between the daytime side and night-time side temperatures, and these are also responsible creating the wild, gale force winds buffeting this beautiful marble blue world amongst the stars.

Out With The Thermal Undies! In With The Anti-Radiation Undies!!   26 comments


Out With The Thermal Undies!

In With The Anti-Radiation Undies!!

Anti-radiation underwear_swimwear

As most people will realise even if they’re not particularly interested in realising, radiation levels near the infamous Fukushima Dai-ichi nuclear plant site in Japan are still unsafe, but surprise, surprise, there have also been concerns that contaminated water might just, possibly, by some remote and wholly inexplicable chance 😉 be making its way out of the radio-active hot zone.

However, courtesy of the money grabbing on the back of the nuclear disaster, Japanese company, the Yamamoto Corporation an exciting new range of anti-radiation underwear and even swimsuits are now available to the intrepid N-plant worker and the slightly over-enthusiastic extreme tourist.

Anti-radiation Swimwear Smile

Designed first and foremost for the Fukushima emergency workers still engaged in the unenviable and altogether far too hazardous job of cleaning up the plant, this flattering offering from Yamamoto Corporation will undoubtedly prove a hit with those swimming enthusiasts looking to escape the ice and cold of winter, albeit in a radio-active hot zone, or even those preparing themselves mentally and physically for the 2014 Valhalla Basin Winter Galactic Olympics. (Granted they could have had a similar experience swimming in the Methane seas of Titan, Saturn’s moon, but the enticing prospect of basking in the hot zone around the Fukushima N-plant swimming playfully in its radio-active waters Winking smile is apparently a temptation the Yamamoto Corporation, for reasons best known to themselves, consider too great to endure… well whatever takes your fancy. And extreme tourism can carry its own unique notoriety after all…. Smile

This charmingly styled anti-radiation swimwear range, bearing a close resemblance to a deep-sea diver’s wetsuit is designed to protect the intrepid wearer when they take the plunge and enjoy a nice, hot, full-body dip in the radioactive water Smile is made from a bio-rubber material that contains microscopic bubbles – clever little bubbles and not at all like those you find in your snuggly hot bubble bath… oh no, these are special bubbles and deflect almost 100 percent of beta particles. Could get very hot and sticky in there but then again if you insist in swimming in a radioactive hot zone presumably you don’t care…SmileAnd neither will you mind pretty little price tag for these wetsuits which will set you back ¥150,000 ($1,078) Surprised smile

Anti-Radiation Underwear

So now you’re all hot under the radio-active collar and ready to rock and roll, next up is the Anti-Radiation Underwear Smile

Yes! Out with the thermal undies and in with the anti-radiation undies! Tastefully styled to protect the lower spine and pelvic area, these 7lb beautieslead infused anti-radiation undies are purpose designed to protect those all-important bits and bobs of you that you really, really really don’t want bombarded with heavy duty radiation Winking smile Of course they could prove a touch impractical…a little weighty perhaps….possibly bordering on the manically bulky side… Winking smile but think of the peace of mind these 7.5 lb. undies will give you Smile Block out the majority of those highly radioactive gamma rays…slam the door completely in the face of all those other lesser breeds of ionizing radiation and worry no more! You are wearing your anti-radiation undies! And they will cost you a mere ¥80,850 ($829) Surprised smile A mere drop in the radio-active ocean. Smile

Snow White And The Frozen Dwarf   27 comments

 

Snow White – World of Ice and Methane

Snow White (Photo Credit: NASA)US Astronomers at the California Institute of Technology (Caltech) have discovered that the dwarf planet 2007 OR10 known as Snow White –once a small volcanically active world firing slushy water ice from ancient volcanoes, and boasting an atmosphere, is today an icy, frozen, dead world, tinged red and enveloped in a thin layer of methane that is slowly slipping away to be lost into space.

Snow White — orbits the sun at the edge of the solar system and is about half the size of Pluto, making it the fifth largest dwarf planet. Part of a larger group of icy bodies called Kuiper Belt Objects (KBOs).Ironically Snow White has actually proved to be one of the reddest objects in the solar system.

However last autumn using a newly designed instrument called the Folded-port Infrared Echellette (FIRE), with the 6.5-meter Magellan Baade Telescope in Chile, Adam Burgasser, a former graduate student and now a professor at UC San Diego, and Wesley Fraser, postdoctoral scholar were shocked to find out although Snow White was indeed red, it’s surface was also covered in water ice.

“Water ice is not red! Although ice is common in the outer solar system, it’s almost always white~ Mike Brown, the Richard and Barbara Rosenberg Professor and professor of planetary astronomy.

One other dwarf planet that shares these characteristics is Quaoar, discovered in 2002. Slightly smaller than Snow White, Quaoar is still big enough to have had an atmosphere and a surface covered with volcanoes that sent-up and slush and ice, which as with Snow White flowed over the surface before freezing solid.

But smaller than dwarf planets like Pluto or Eris, it was unable to hold onto volatile methane, carbon monoxide, or nitrogen compounds as long. And two billion years after its formation Quaoar inevitably began to lose its atmosphere to space; now, and today all that remains is the space-irradiated methane which rests on the icy surface Quaoar’s, giving it a glowing reddish hue.

It is clear from indications on the spectrum of Snow White 2007 OR10 which clearly shows the presence of water ice that it too for the last ½ billion years it has followed in the footsteps of Quaoar, still and silent amongst the stars, slowly losing its atmosphere into space until now only a small part remains."

The existence of methane is still open to debate. But the use of a large telescope such as the Keck Observatory will show clearly whether methane exists on Snow White or not. If this proves to be so it will join Quaoar as one of only two dwarf planets that bridge the gap between the tiny selection of entities large enough to hold onto hazardous composites, and the smaller entities that constitute the vast majority of KBOs.
