MessageToEagle.com - There is a strange alien planet orbiting an orange dwarf star in the constellation
Monoceros bordered by the constellations of Canis Minor, Gemini, Hydra, Lepus, Orion and Puppis and located 490 light years away.
Detected by the CoRoT satellite in 2009, CoRoT-7b is the smallest, (with diameter of only 1.58 times that of the Earth
and fastest-orbiting exoplanet yet discovered.
The smaller the orbit, the faster the planet circles its star, and therefore CoRoT-7b travels at more than 750,000 kilometers per hour!
Astronomers detected the new planet as it transited its parent, a Sun-like star, dimming the light from the star
as it passed in front of it.
The discovery gave some hope about its density, which was under investigation.
Was this rocky body similar to Earth or a class of planets which are thought to be made up of water and rock in
almost equal amounts?
Given the high temperatures measured, the planet would be a very hot and humid place.
However, the planet's "true" face was unknown until astronomers led by Professor Bruce Fegley from Washington University,
began to model the alien planet's atmosphere.
The planet's extreme conditions make that it cannot sustain life or most probably any life at all.
CoRoT-7b is a hellish world - too hot for any life. There is no water cloud forming and water droplets
raining on the planet's hot surface.

Astronomers who have worked on computer models to create an exotic environment of this alien world say that a rain of
pebbles falls from clouds of rock vapour into lakes of molten lava and the exoplanet's surface, covered with boiling
oceans, has temperature which is hot enough to boil rock.
The planet is only 1.6 million miles from its star, which means 23 times closer than the innermost planet in our solar
system, Mercury, is to the Sun.
Due to its location, (only 2.5 million kilometers from its host star) the planet planet is gravitationally locked,
like the Moon to the Earth, so that one side of the planet always faces the star. CoRoT-7b's far side is in never
ending darkness - around 50 degrees above absolute zero, while its near side experiences 2,800C.
One of the methods for detecting exoplanets is to look for the drop in brightness they cause when they pass
in front of their parent star. Such a celestial alignment is known as a planetary transit.
From Earth, both Mercury and Venus occasionally pass across the front of the Sun. When they do, they look like tiny
black dots passing across the bright surface. Such transits block a tiny fraction of the light that COROT is able to detect. Credits: CNES
"CoRoT-7b is so close that the place may well look like Dante's Inferno, with a probable temperature on its 'day-face'
above 2,000 degrees and minus 200 degrees on its night face," says Didier Queloz, who led the team that made the
CoRoT-7b discoveries.
CoRot-7b is perhaps Earth-like object but it's definitely not like our planet and will never be!

Millennia Old Astronomical Secret Revealed
In 1943, an ancient papyrus was bought by the Cairo museum.
It was written in Hieratic and although portions of it were eaten away by ants, it was a very precious ancient document.
The papyrus contained three separate books dealing with astronomy. One of the books was the Cairo Calendar, and now it reveals an ancient astronomical secret...
Most Alien World We Can Only Imagine
This is not an alien world, anyone of us will ever be able to visit.
It's not very far away, only about 40 light years from Earth, but it circles dangerously close to a stellar inferno, completing
one orbit in only 18 hours. The alien planet named "55 Cancri e" is 26 times closer to its parent star than Mercury is to the Sun.
The temperature on the surface of 55 Cancri e is estimated to be as high as 2,700 degrees Celsius.
Big Bang Machine Discovers Unknown Particle
Physicists at Cern have not yet been able to confirm the existence of
the elusive "God particle", but they have nevertheless made another interesting discovery
Scientists announced that the Large Hadron Collider, often referred to as the Big Bang machine has detected an unknown particle composed of three quarks.

Watching Volcanoes On Alien Worlds
Volcanoes display the awesome power of nature like few other events.
Now that astronomers are finding rocky worlds
orbiting distant stars, they're asking the next logical questions: Do any of those worlds have volcanoes? And if so, could we detect them?
Aliens Living On Methane Worlds
In the search for life elsewhere, many studies focus on finding liquid water. But what if life could exist with some other
solvent? Saturn's smoggy moon Titan makes scientists question the possibilities for methane-based life in the galaxy.
The search for life is largely limited to the search for water – we look for exoplanets at the correct distance from their
stars for liquid water to splash and flow freely on their surfaces...
Record-Breaking Radio Waves From Ultra-Cool Brown Dwarf
Flaring radio emissions from an ultra-cool star, not much warmer than the planet Jupiter, have been discovered by Penn State astronomers
using the world's largest radio telescope, at Arecibo, Puerto Rico.
This is by far the coolest brown dwarf yet detected at radio frequencies...
Light From Distant Alien World Seen For The First Time
It's the most alien world we can only imagine and for the first time a space-based infrared telescope - Spitzer Space Telescope -
has detected light emanating from a "super-Earth" located in this system and orbiting a bright star, known as 55 Cancri, in a mere 18 hours.
Earth-Like Exoplanet In The Habitable Zone Could Harbor Life
- Has Earth Twin Been Discovered?
It is every astronomers' dream to find an Earth-like with liquid water and perfect conditions for life, as we know it.
This is why the recent discovery is so exciting.
An international group of astronomers have detected a new exoplanet that appears to be very similar to Earth. Could life exist there?
Mercury Surprises Scientists
On March 17, MESSENGER (MErcury Surface, Space Environment, GEochemistry, and Ranging) completed its one-year primary mission, orbiting Mercury, capturing nearly 100,000 images, and recording data
that reveals new information about the planet's core, topography, and the mysterious radar bright material in the permanently shadowed areas near the poles.
Living Earth Simulator - Supercomputer Predicting The Future
In Douglas Adams book the Hitchhikers Guide to the Galaxy we encounter a machine called Deep Thought. It is the most powerful computer ever built. Deep Thought is capable of answering questions
