Exoplanets
An exoplanet is a planet which orbits a star outside our solar system. The discovery of Gliese 581c caused excitement because the exoplanet's surface is the right temperature to support alien life. In 1995 astronomers were amazed to see over 3,000 galaxies when they pointed the Hubble Space Telescope to a dark corner of Ursa Major. If an average galaxy contains 100 billion stars, and there is a one per cent chance of a star being orbited by an Earth-like habitable planet, that's a pretty good chance of extra-terrestrial life.
This ‘rogue’ planet is now the fastest-growing world we've ever seen
It might be a planet, but it’s growing up more like star
Astronomers have spotted a solar system being born for the first time

Exoplanet shaped like a rugby ball spotted by Cheops telescope
The discovery could help to shed light on the internal structure of planets.
Inside the mission to spot an alien city by harnessing the Sun’s colossal gravity
Astronomers generally view the Sun as an obstacle to the objects they want to study. But it might just be the key that enables them to observe Earth-like exoplanets located many light-years away.
Planet Earth may be far more special than we think
Very few potentially habitable planets meet the conditions necessary to produce an atmosphere suitable for the evolution of complex life as we know it, study says.
Discovery of exoplanet’s bizarre orbit may help us track down Planet Nine

Ariel, which will launch in 2029, will focus on planets unlikely to host life as we know it.
Can life exist around a black hole?
New research suggests that 'Goldilocks zones', where planets could have the perfect conditions for life, could exist near supermassive black holes.

Astronomers say their findings open the search for life up to planets significantly larger than Earth, but smaller than Neptune.
Jupiter-like exoplanet orbits its star in only 18 hours
The discovery may help solve the mystery of whether such exoplanets are in the process of spiralling towards their suns to their destruction.
