The tiny natural satellite was found orbiting an asteroid.

The Artemis 1 mission will use a Space Launch System megarocket to launch an Orion spacecraft to the moon.

In space, no one can hear you scream—until now.

A form of matter called plasma, which contains charged particles, could help break up the Martian atmosphere into more useful components

In the void of interstellar space, the most distant emissary of humankind carries a message that will last for billions of years.

'Spectral siren' method suggests mergers between massive and compact cosmic objects could help understand how the universe has evolved.

Gases trapped in lunar meteorites hint that the moon was formed out of material displaced from Earth after a planetary collision.

In August, NASA is sending an orbiter to the space object, which may be the partial remains of planet-forming material made of nickel and iron

A team of researchers, led by Swinburne's Professor Akbar Rhamdhani, has published the first detailed study of its kind on metal production on another planet.

NASA is aiming for a 2024 moon landing — and this time, it won't just be men making the trip.

Astronomers have identified one of the youngest exoplanets ever discovered, hidden in the swirl of gas around a newly born star 390 light-years from Earth.

But Earth is 100 times more likely to be destroyed by an asteroid than invaded by aliens.

Zeta Ophiuchi has had an interesting life. It began as a typical large star about twenty times more massive than the Sun. It spent its days happily orbiting a large companion star until its companion exploded as a supernova about a million years ago. The explosion ejected Zeta Ophiuchi, so now it is speeding away through interstellar space. Of course, the supernova also expelled the outer layers of the companion star, so rather than empty space...

H.G. Wells’ book “The First Men in the Moon” depicts alien life in lunar caves.

Even NASA's next-generation space observatory can't manage to see supermassive black holes directly, but that doesn't mean astronomers can't use its data to better understand the mysterious behemoths.

How many galaxies should we see shortly after the Big Bang?

The two galaxies, if confirmed, existed 300 to 400 million years after the Big Bang.

The timeline could still certainly shift in the coming weeks.

When the James Webb Space Telescope (JWST) reveals its first images on 12 July, they will be the by-product of carefully crafted mirrors and scientific instruments. But all of its data-collecting prowess would be moot without the spacecraft’s communications subsystem. The Webb’s comms aren’t flashy. Rather, the data and communication systems are designed to be incredibly, unquestionably dependable and reliable.

NASA has released images of Jupiter taken during James Webb's commissioning period..
