Astronomers have found evidence of the most powerful explosion in the universe. The crater of the intergalactic-scale detonation was caused by a supermassive black hole located in the Ophiuchus galaxy cluster 390 million light-years from Earth.

Astronomers have analyzed the atmosphere of a large exoplanet and found that it could have liquid water – and so possibly life – on its surface. This new study adds weight to the idea that habitable exoplanets don’t have to be strictly Earth-sized.

In a significant first for commercial satellites, Northrop Grumman's Mission Extension Vehicle-1 has docked with an aging communication satellite in order to extend its service life after almost two decades in orbit.

The Minor Planet Center has announced that Earth now has two moons. But don’t bother running outside to check – this second satellite is tiny and temporary. The newcomer, designated 2020 CD3, measures between 1.9 and 3.5 m (6.2 and 11.5 ft) wide.

China’s pioneering mission to explore the far side of the Moon continues to shed new light on this relatively unknown territory, with scientists using instruments aboard the Chang'e-4 spacecraft to peek beneath the surface for the first time.

NASA wants help designing a vital element of a rover that could one day explore Earth’s hellish twin, Venus. The component would allow the rover to safely explore the surface, and must be capable of enduring a brutal alien environment.

Virgin Galactic has announced a new drive to recruit passengers for flights on its SpaceShipTwo suborbital spaceplane. For a deposit of US$1000, aspiring astronauts can to get to the front of the line when firm seat reservations become available.

The Insight lander's primary sensor has pulled in the first ever direct measurements of seismic activity on Mars, which mission scientists can use as window to better understand the planet’s insides and its potential to harbor life.

Astronomers have spotted a tiny, cool star putting on a stellar light show that would shame our Sun. This X-ray “superflare” was 10 times more powerful than anything the Sun can produce, and is completely unexpected for a star this small.

Japan is moving ahead with a first-of-a-kind mission to explore the two moons of the Mars system. All going to plan, the Martian Moon Exploration mission will return to Earth with the first ever samples of a Martian moon by the end of the decade.

Space Adventures has announced that it has signed an agreement with SpaceX to fly paying passengers aboard the aerospace company's Crew Dragon spacecraft, which will mark the first time that space tourists will be launched aboard an American rocket.

Virgin Galactic has come one step closer to full commercial operations as it relocates its SpaceShipTwo, VSS Unity, from the company's manufacturing facility in Mojave, California, to its Spaceport America’s Gateway to Space building in New Mexico.
