Friday, March 1, 2013
An international team of astronomers has used nearly three years of high precision data from NASA's Kepler spacecraft to make the first observations of a planet outside our solar system that’s smaller than Mercury, the smallest planet orbiting our sun.

When astronomers discovered planet GJ 1214b circling a star more than 47 light-years from Earth in 2009, their data presented two possibilities. Either it was a mini-Neptune shrouded in a thick atmosphere of hydrogen and helium, or it was a water world nearly three times the size of Earth.
Astronomer Jacob Bean used a new method...

It's a potentially habitable planet that's orbiting a nearby star, that's capable of having liquid water and thus supporting life as we know it.
In the Huffington Post, Mike Wall quotes astronomer Steve Vogt as saying, "This discovery is in keeping with our emerging view that virtually every star has planets, and that the galaxy...

Lately, astronomers have been searching for life on the MOONS of planets
, but they've also discovered a new planet--one that wandering through the galaxy "homeless," rather than orbiting around a star.
Researcher Jonathan Gagné says, "Over the...

Astronomers have discovered another potentially habitable planet--that's 7 times the mass of Earth. Six planets orbit dwarf star HD 40307g, and one of them is believed have the potential to support human life.
The planet seems to be rotating on its own axis, instead of having one face permanently turned toward its sun, meaning it has...

A system of planets has been discovered in the constellation Cygnus orbiting a double star. It was not thought that this was possible, and planetary scientists are saying that it will lead to a complete revision of our understanding of how planets are formed. It means that they may be even more numerous than we thought, making life...

An Earth-like planet recently spotted outside our solar system is the first that atromomers have found that could support liquid water and harbor life
is what astronomers look for, and the...

Astronomers are discovering more Earth-like planets
almost every day
. Now an international team of astrophysicists has discovered a ring system in the constellation Centaurus that can be...

At the first Christmas
, three astrologers followed a star that shone so brightly, it looked like a diamond in the sky. A new study suggests that some stars in the Milky Way could harbor "carbon super-Earths...

When our satellites search for other planets that might harbor life, they always search for water. But now, for the first time, astronomers have detected around a burgeoning solar system a sprawling cloud of water vapor that's cold enough to form comets, which could eventually deliver oceans to dry planets. And with oceans, life could spring up--...

Some people think our sun has a twin
can still listen to this show). We don't known whether or not this is true, but NASA HAS discovered a planet about the size of Saturn that is orbiting...

Are we isolated in our lonely little corner of the Milky Way? Quasars are highly luminous objects that emit light over a wide range of wavelengths, revealing elements such as hydrogen, nitrogen, silicon, carbon and iron in the gas around them, and measurements on the light from distant quasars reveal that our part of the universe is fine-tuned to...

An incredible discovery has been made by NASA recently: A new planet
that's the right size and location for life and only 20 light-years away, in a solar system very similar to our own but much smaller. The newly-discovered planet is called Gliese 581g and is the first world...

How can something REALLY LARGE be hidden from sight? If it's an object in space, astronomers can know it's there from the reactions of other stars and planets, even if they can't see it. They have evidence that either GIANT brown dwarf ("cold") star or a HUGE gas giant planet is at the outermost reaches of our solar system, far beyond...

The Master of the Key predicted we would find new universes?and we have. Astronomers have also discovered a viable new Earth-like planet that's fairly close to us.
US astronomers say they have found a new planet orbiting around a star that is only 41 light years from Earth. That means that if we could learn how to travel at half the...

Researchers are searching the solar system for a planet?like ours?that could sustain life. One of the first things they look for is water.
In the July 12 issue of the Independent, Steve Connor writes about the discovery of a planet where one side is "bathed in perpetual daylight while the other is kept in infinite night. Here, an entire...
Friday, April 27, 2007
We recently reported on the discovery of an Earth-like planet that is fairly nearby (in space terms, anyway). We wrote that astronomers are already making plans to explore it. In the meantime, they can find out if there is life there from right here on earth.

Astronomers have found the most Earth-like planet they've ever seen outside our solar system. It should even have water running on its surface.
The planet orbits a star which is 20.5 light-years away in the constellation Libra. BBC News quotes astronomer Stephane Udry as saying, "We have estimated that the mean temperature of this '...

Mountains of diamonds, free for the taking? Astronomers say a planet like this may someday be discovered orbiting a newly-discovered nearby star.
Ker Than writes in space.com that astronomers have detected large amounts of carbon gas in a newly forming solar system around Beta Pictoris, a young star that nearby. This means that in a few...

Spaceref - A team of astronomers has found the most Earth-Like PlanetYet to be discovered outside our solar system. It's aboutseven-and-a-half times as large as Earth, and it may be thefirst non-gaseous planet ever found that is orbiting arounda normal star like our Sun. Astronomer Michael Turner says,"[These] results are an...

If extraterrestrial life does exist, scientists think they've found the star that?s orbited by the planet it's on?a middle-aged star in the constellation Gemini. Out of 30 possible solar systems, this one is the best.
Astrobiologist Maggie Turnbull has made a list of 30 stars with planets that could harbor life and found that the one...

Our solar system may have had another planet, that was swallowed up by the Sun. But before it was destroyed, this planet caused a lot of problems.
Space scientists John Chambers and Jack Lissauer of NASA think that along with Mercury, Venus, Earth, and Mars there was another planet, just outside of the orbit of Mars and inside the...
