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.

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.

Pan Galactic Space Goat   71 comments

 

Capricornus – The Celestial Sea Goat

Capricornus - The Goat -The Constellation

CAPRICORNUS – its correct astronomical title, is a very faint constellation also known as the zodiac sign Capricorn by astrologers. It shares a part of the night sky with fishes, whales, rivers, and water carriers. Despite being depicted as a sea goat it bears closer resemblance to a triangle or if you’re a Halloween fan, witches pointed hat.

Originating with the ancient Sumerians and Babylonians, the constellation Capricornus was known as SUHUR-MASH-HA, THE GOAT FISH.

Pan - Half Goat_Half Fish

Pan The God Of The Countryside

The Greeks, however called it AEGOCEROS (GOAT-HORNED). The name of the well-known Italian island – “CAPRI” means “THE ISLAND OF GOATS” but the star atlas’s of old indicate that ancient Greeks associated the constellation Capricornus with the god of the countryside known as Pan. Pan was said to have had the head, horns and forelegs of a goat and a fish’s tail.

Pan, A Playful And Mischievous God

PAN was a very mischievous and naughty god who spent as much time as he possibly could chasing goddesses and female sea nymphs. These activities were punctuated with periods of sleep and relaxation aiming to aid a speedy recovery from his exertions and to renew his strength for his next session of very naughty behaviour.

Syrinx The Nymph

Not all his seductive godly ways turned out as planned – THE NYMPH “SYRINX” was so un-entranced by his godly charms that she transformed herself into a bunch of reeds to avoid his attentions. Ever hopeful, Pan grabbed hold of them and was surprised when they created an un-expectedly beautiful musical sound as the wind blew gently through them.

Inspired and greatly pleased by this discovery Pan waxed together several of varying lengths so forming today’s PAN PIPES (SYRINX)

Pan seduces the nymphs and goddesses

So it comes as no great surprise that Pan, on being fortunate enough to come across a wild and wicked field party hosted by naughty sea nymphs and goddesses was only too happy to gate crash it and indulge in all kinds of untold fun and mischief.

Typhon The Terrible

Pan’s indulgences were however rudely interrupted by the approach of the huge and ferocious Typhon – a monster sent by Gaia – Mother Earth to attack the gods. After booming a deafening warning to the gods (being something of a loud mouth) Pan’s suggested each god transformed themselves into a different kind of animal and fled to a place of safety in order to escape the terrible Typhon.

To the amusement of the passing god ZEUS THE GOD OF THUNDER, Pan in great alarm, (hence the term panic) dived into the nearest river intending to transform fully into goat-form. Things did not go quite to plan and the lower part of his body changed into that of a fish!

The Mighty Battle of Zeus

Zeus fought a mighty battle with Typhon eventually overcoming him with thunderbolts, after which SICILY’S MOUNT ETNA became the monster’s final resting place. Refusing to rest even in death Typon’s breath was said to be responsible for the fiery, volcanic eruptions produced by Mt Etna.

During this battle Zeus was badly injured and was left unable to run or fight. Pan with the help of Hermes repaired the damage done to him and he was able to continue with the battle and onto victory.

By way of thanks Zeus placed an image of Pan – the sea goat Capricornus, in the night sky.
