欧洲南方天文台于美国东部时间4月24日公布了新发现的行星“Gliese 581 c”围绕红矮星“Gliese 581”运转的模拟图。天文学家认为，这颗行星可能适合 ...

模拟图的灰色球体为新发现的疑似宜居星球。红色星球被称为红矮星Gliese 581，类似于太阳系中的太阳，但比太阳小得多，温度低得多。 Gliese 581c行星 ...

But Gliese 581 c and d could very well be big icy planets, with a very different composition from the Earth. [2] The team led by F. Selsis (CRAL and LAB, France) includes J.F. Kasting ...

Gliese 581 is a red dwarf located 20.5 light-years from Earth, in the constellation Libra. Like other red dwarfs, it's smaller and much dimmer than our sun.

Both teams found that, while Gliese 581 c is too close to the star to be habitable, the planet Gliese 581 d might be habitable. However, the environmental conditions on planet d might be too harsh ...

Gliese 581c is a super-Earth planet that was discovered in 2007. It resides in the Gliese 581 system, which at 20 light-years from Earth is relatively close to our planet (in celestial terms).

Following the latest estimation, Gliese 581 would be 7 Gyr-old. The purple bars surrounding planets Gliese 581 c and d illustrate the variable distance to the star caused by the eccentricity of ...

Gliese 581 d is seven times as heavy as the Earth, which puts it in the class of the so-called super-Earth planets. There is every indication that because of the massive rocky planet, ...

Gliese 581 g shot to the top of a list put out by researchers at the University of Puerto Rico at Arecibo’s Planetary Habitability Laboratory (PHL) after a new study marshaled support for its ...
