Stars

In 2016, astronomers discovered a potentially habitable Earth-sized exoplanet just four light-years away – and new observations suggest it isn’t alone. A second planet may be orbiting Proxima Centauri, the closest star to the Sun.

The LIGO collaboration has announced the detection of gravitational waves from a pair of neutron stars colliding. This marks just the second time ever that this kind of event has been spotted, as the smash-up sent ripples through spacetime itself.

NASA has released a new panoramic infrared image of the center of the Milky Way. With data gathered by the Boeing 747-based SOFIA observatory, the image reveals new details of certain regions that have been traditionally tricky to capture.

The cosmic beauty of space never ceases to impress. New Atlas rounds up some of the most incredible space photos of 2019, including historic firsts, stunning starscapes, gorgeous galaxies and some new angles on our own solar system.

ESA has successfully launched its Cheops telescope on a mission to make detailed follow-up studies of distant exoplanets discovered by earlier space-faring telescopes, such as Kepler and TESS.

Scientists have discovered a massive planet evaporating as it orbits the remains of a Sun-like star. This is the first time evidence of a huge planet orbiting a white dwarf has been observed, and it could help reveal the fate of our own solar system.

Black holes are mysterious objects: just when we think we understand how big they can get, we go and find new ones that bend the rules. Now, astronomers have found a stellar black hole in our galaxy that’s so big it defies explanation.

On February 23, 1987, a supernova lit up the night sky, visible to the naked eye for the first time in almost 400 years. Now, more than 30 years on astronomers say they’ve finally found the neutron star that was produced in the explosion.

Astronomers have discovered a star known as S5-HVS1, travelling at an incredible 6 million km/h (3.7 million mph). That not only makes it the fastest known star, but it’s fast enough to fling it right out of the galaxy.

Black holes come in a few different sizes, from modest ones a few times heftier than the Sun, right up to supermassive monsters at the heart of galaxies. But now researchers claim to have discovered the smallest black hole ever detected.

Wormholes are a sci-fi staple – but could they be science fact? Surprisingly they fit into current physics models, although no evidence has ever been found. Now, researchers have outlined how we might go about looking for wormholes in our own galaxy.

If other star systems are anything like our own, they’ve probably had turbulent histories of exoplanets smashing into each other. And now, astronomers have found evidence of just such a cataclysm happening in the relatively recent past.
