In 1924, astronomer Edwin Hubble realised two objects were too distant to be inside our galaxy.
New analysis of radio telescope data links the shape of galaxies to the supermassive black holes they host.
Astronomers have detected possible signs of gases released by volcanic activity.
On what would’ve been the astronomer’s 90th trip around the Sun, here’s a look at his legacy as a scientist, advocate and communicator.
Cosmology could be transformed by a new wave of telescopes – both on the ground and in space.
Two new studies show that the majority of meteorites originate from just one family of asteroids between Mars and Jupiter.
Comet Tsuchinshan-ATLAS is one of 2 comets from the Oort Cloud passing by Earth in October 2024.
Before sending humans to Mars, NASA will first return humans to the Moon’s surface to test its technology and train astronauts.
Earth’s tilt means the Sun both rises earlier and sets later as we head towards summer.
Some of the earliest galaxies found with JWST are also the brightest. That’s a problem for our ideas about the universe.
In 2022, a probe was sent crashing into an asteroid as part of a “planetary defence” test. This Monday, the second part of the mission flies off to study the consequences of the impact.
Argentina and Chile will see the ‘ring’, but other regions will see a partial eclipse.
Parts of South America, the Pacific and Antarctica are under the path of an annular eclipse.
CubeSats have already visited the Moon and Mars and are key components of upcoming deep space missions.
Comet C/2023 A3 (Tsuchinshan-ATLAS) is expected to be the brightest spectacle of 2024. Our charts will help you find it in the night sky.
A large space rock will be temporarily captured by Earth’s gravity throughout October and November.
The Hubble tension has been described as a “crisis” for cosmology. Can it be resolved?
Astronomers have found a true colossus of a jet in the night sky, over 100 times larger than our galaxy. It’s almost perfectly straight, which presents a puzzle.
This month, they spotted just the ninth asteroid to be detected before impact with Earth.
