No one has seen this planet, but the oddities of the orbits of objects in the icy outer reaches of the Solar System suggest that there is something very massive behind Pluto.
A small piece of rock found in a field in Gloucestershire in the UK may contain vital information about the formation of the Solar System and the origin of life itself.
Isotopes have been discovered for the first time in the atmosphere of a planet more than 300 light-years away from Earth.
Astrobiologists from the University of Arizona suggest that an excess of methane in Enceladus emissions may be a marker of life in the subglacial ocean of Saturn's moon. Biologists from the University of Belfast have come to the conclusion that no known life forms are possible in the clouds of Venus. Glaciologists at the University of Bristol have discovered bacteria that feed on rocks under the ice of Antarctica.
Computers powered by stars can be a sure sign of the existence of extraterrestrial intelligence, says Anders Sandberg from the Oxford Institute of Humanities.
What happens when the Sun goes out
Jupiter's icy moon, Europa, may have enough internal heat to trigger volcanic activity at the bottom of its vast ocean, according to a new study. Despite the fact that Europa is encased in a shell of water ice, it is considered one of the most promising places in the Solar System to search for extraterrestrial life.
To date, more than 4,000 exoplanets orbiting the stars of the Milky Way have been identified and confirmed. There is a curious pattern among them: there are very few exoplanets 1.5–2 times the size of Earth. But why is this happening?
The hydroxyl (HO) molecule is common on Earth, but astronomers have not yet determined how common it is on other worlds. It was all the more amazing to find her on a planet where a red-hot hell reigns.
To get the most useful information about cosmic bodies, it is sometimes very useful to look at them not only in the visible spectrum of light.
