This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. When a star passes within a certain distance of a black hole -- close enough to be swallowed up -- the stellar material gets stretched and compressed as it is pulled in. A black hole’s destruction of a star, called ‘stellar tidal disruption,’ releases an enormous amount of energy, brightening the surroundings in an event called a flare.

Future telescopes like the NASA/ESA/CSA James Webb Space Telescope (right) will observe the atmospheres of distant planets to seek evidence of life. Earth (top left) has several gases in its atmosphere that reveal the presence of life, primarily oxygen and ozone. Krissansen-Totton et al find that for the early Earth (bottom left), the combination of abundant methane and carbon dioxide would provide an alternative sign of life.
