The new planet is believed to be orbiting Barnard's Star, a red dwarf that's not visible to the naked eye but one of the closest stars to our Solar System.
Astronomers have suspected them for ages –now a team as finally spotted a 'fountain' in a galaxy far, far away.
The Gaia satellite has uncovered the remains of a galaxy buried deep in the Milky Way.
Are there stars other than the Sun that might explode soon close to us? Yes, there are! As long as by 'soon' we mean within a million years.
Astronomers think they've identified which galaxy was the source of a blast radio energy, over in a fraction of a second. And it's much closer to us than the others detected, so far.
There are lots of places where it's much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
From sun dials to atomic clocks, we still don't have a perfect time measuring device.
Merging supermassive black holes would emit gravitational waves, allowing scientists to detect them.
Whether you call it Planet X or Planet Nine, talk of another planet lurking in our Solar system won't go away. So what does the discovery of a new object – nicknamed "The Goblin" – add to the debate?
The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.
We still don't know what causes these mysterious Fast Radio Bursts deep in the universe, but we've detected a whole new batch of them.
The 'oldest known nova' (a star explosion) in the sky was actually not a nova, astronomers show.
Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.
Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving 'forgotten' scientists due credit.
We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
By sharing a location with the SKA, HIRAX will be able to conduct science in “radio-clear” skies across its wide frequency range.
To better detect gravitational waves, we need to build the quietest and most isolated thing on Earth. And make sure we don't drop those 40kg mirrors.
The planets we can see in the sky were known to the ancient Greeks as 'wandering stars'. But they appeared much earlier in the stories and traditions of Australia's Indigenous people.
A podcast all about nothing. From the importance of doing nothing to the ill-effects of time spent in solitary confinement and what nothing means in space.
It's all about the strong gravitational field of the black hole.
