First Rocky Exoplanet Confirmed 155

Posted by Soulskill

Matt_dk writes "The confirmation of the nature of CoRoT-7b as the first rocky planet outside our Solar System marks a significant step forward in the search for Earth-like exoplanets. The detection by CoRoT and follow-up radial velocity measurements with HARPS suggest that this exoplanet has a density similar to that of Mercury, Venus, Mars and Earth, making it only the fifth known terrestrial planet in the Universe. The search for a habitable exoplanet is one of the holy grails in astronomy. One of the first steps towards this goal is the detection of terrestrial planets around solar-type stars. Dedicated programs, using telescopes in space and on ground, have yielded evidence for hundreds of planets outside of our Solar System. The majority of these are giant, gaseous planets, but in recent years small, almost Earth-mass planets have been detected, demonstrating that the discovery of Earth analogues — exoplanets with one Earth mass or one Earth radius orbiting a solar-type star at a distance of about 1 astronomical unit — is within reach."

    I appreciate the Rocky movies and all, but there's no way I would live on a whole planet dedicated to them. I'm fine here on Earth, thank you very much.

    We recieved some radio transmissions, but all we've decoded so far is You're the best around and Eye of the Tiger.

    Maybe jump to the left?

    Then a step to the right, perhaps?

    What... too late?

    In the grand tradition of selling things you don't own, like the names of stars and acres on the moon, I hereby offer to sell 40 acre lots on this planet for a mere $10,000 each. That's cheaper than a lot this size would cost in any large city here on earth. Imagine what you could do with your lot. Since there isn't any law enforcement there yet, you could grow illegal crops, build a manufacturing plant without any polution controls, or just use it to test your nuclear bombs. This is a limited time offering, and quantities are limited, so don't delay. And if you order today, we'll include the plans for a trebuchet so you can fling dead animals onto your neighbors property.But wait, order during this program, and we'll include a set of ginzu knives (shipping, handling, and other fees are an additional charge) which can cut through the toughest tomato without the need for a hammer, but you'll want to use one anyway just for the splattering fun.

    This what the actual radio transmission looked like.

    |x3xxxxxxxxxxxxxxx3xxxxx1xxxxx3xx|xxxxxxxxxxxxxxxx3xxxxx1xxxxx3xx|

    Repeated about 3 or 4 times.

It is better to give than to lend, and it costs about the same.
