Metal-poor stars more likely to have planets with alien life - study

While one might think metal-rich stars would be more likely to have planets with life, planets around metal-poor stars have better shielding to UV radiation.

Get your telescopes ready: Five planets to align on Monday

Scientists recommend finding a clear view of the western horizon and using binoculars to view the planets.

 This artist's impression shows two Earth-sized worlds passing in front of their parent red dwarf star, which is much smaller and cooler than our Sun. The star and its orbiting planets TRAPPIST-1b and TRAPPIST-1c reside 40 light-years away.

Is this the most volatile exoplanet ever seen in space? - study

Exoplanet VHS 1256 b is a gas giant 40 light years away from Earth that orbits a binary star system. Its constant shifts in brightness with its clouds make it the most volatile world ever seen.

Sci-fi made reality? Alien life could exist on tidally locked worlds - study

Tidally locked worlds have one side always day and another always night. Life should be impossible here, but a strip in the middle could support life.
