We show that terrestrial planets in the habitable zones of M dwarfs older than *1 Gyr could have been in runaway greenhouses for several hundred million years following their formation due to the star’s extended premain sequence phase, provided they form with abundant surface water. Such prolonged runaway greenhouses can lead to planetary evolution divergent from that of Earth.
Astronomers have studied the carbon monoxide in a galaxy over 12 billion light years from Earth and discovered that it's running out of gas, quite literally, and headed for a 'red and dead' future. The galaxy, known as ALESS65, was observed by the Atacama Large Millimeter Array (ALMA) in 2011 and is one of fewer than 20 known distant galaxies to contain carbon monoxide.
The end of the world is coming – but not for a while yet. That’s according to a new study indicating that we have 1.75 billion years left until Mother Earth gives up the ghost.
