Strange things are happening at the outer edges of our solar system. An object up to ten times the mass of Earth is pulling others towards it. Is it a planet, or something else?

"The system exists against the odds," said Brian Powell, a data scientist at NASA's High Energy Astrophysics Science Archive Research Center about the source of starlight that was mysteriously brightening and dimming some 1,900 light-years awa

In the vein of "go big or go home," the European Southern Observatory (ESO) has launched a stunning new website to showcase information about — and match the scale of — its Extremely Large Telescope (ELT), the highly anticipated observ

NASA declared the InSight Mars digger dead after failing to burrow deep into the red planet to take its temperature.

Red dwarf stars are the most common kind of star in our neighbourhood, and probably in the Milky Way. Because of that, many of the Earth-like and potentially life-supporting exoplanets we've detected are in orbit around red dwarfs. The problem is that

A Harvard professor says we were visited by an alien life form in 2017 and we should be ready for more.

According to statements made by JAXA, the samples returned by the Hayabusa 2 mission included black sand and gases obtained from the asteroid itself. The post Even the Outside of Hayabusa 2's Sample Capsule has Asteroid Debris on it appeared first on

Strange radio transmissions appear to be coming from our nearest star system; now scientists are trying to work out what is sending them

Tantalising 'signal' appears to have come from Proxima Centauri, the closest star to the sun

The sun unleashed its most powerful solar eruption in more than three years on Sunday (Nov. 29).

Scientists think a piece of 1960s space junk has slipped into orbit around Earth. Here's the story of the Centaur rocket body and the Surveyor moon program it powered.

The space agency used the upgraded Deep Space Station 43.

The rapid recovery and analysis of a meteorite that fell onto a frozen lake in Michigan two years ago is illuminating the pivotal role these rocks played in delivering the basic building blocks for life to Earth.

TESS, the Transiting Exoplanet Survey Satellite, was launched in 2018 with the goal of discovering small planets around the Sun's nearest neighbors, stars bright enough to allow for follow-up characterizations of their planets' masses and atmosphe

There really is water on the Moon — and it might be much more widespread than previously suspected.

New research provides the best evidence to date of water ice on the Moon and suggests this valuable resource is scattered widely across the lunar surface.

NASA will fund a project by Nokia to build a 4G cellular communication network on the moon with $14.1 million, the space agency announced Wednesday.

Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our solar system that may have conditions more suitable for life than our own. Some of these orbit stars that may be better than even our sun.

After the observation of phosphine gas on Venus, which may be a sign of life there, a new search through old data has found hints of the gas and more

The discovery of phosphine in Venus' atmosphere has generated a lot of interest. It has the potential to be a biosignature, though since the discovery, some researchers have thrown cold water on that idea. But it looks, at least, like the discovery is
