Habitability of the Goldilocks planet Gliese 581g: results from
... Aims. In 2010, detailed observations have been published that seem to indicate another super-Earth planet in the system of Gliese 581, which is located in the midst of the stellar climatological habitable zone. The mass of the planet, known as Gl 581g, has been estimated to be between 3.1 and 4.3 M⊕ ...

In the ‘steady state,’ there will be at least several billion radiating stars out there. Stars much more massive than the Sun burn up their fuel very quickly, ...

... When analyzing a star’s light, scientists look for spectral “fingerprints,” a pattern of colors different for every individual element, to determine that star’s composition. This process, called spectroscopy, is also useful for determining the chemical makeup of exoplanets and their atmospheres when ...
