The closely-packed group of galaxies is located some 9.7 billion light years away from Earth.

The laser beams, emitted for a few minutes, would be enough to zap the junk into smaller, less harmful pieces.

Nasa satellite images show the contrast between the desert sand and flaky snow in breathtaking images from space.

40 years ago today, NASA revealed its first astronaut class consisting exclusively of women. These astronauts would reach posterity not just as "NASA girls" but as groundbreakers.

While astronomers have predicted this type of event before, it has never been observed directly in a distant galaxy.

The technology works in much the same way as Global Positioning Systems on Earth, albeit on a cosmic scale.

The new five-exoplanet system, dubbed K2-138, is located within the Aquarius constellation and is the first planetary system to be found by citizen scientists.

A 360 degree visualisation allows you to experience travel through distant cosmos.

The new research has implications for understanding how planetary systems form, astronomers say.

A Japanese astronaut has spoken about his amazing growth spurt and concerns that he may not fit into his Earth-bound Soyuz space shuttle.

The spectacular image was taken by the Juno spacecraft from a distance of about 13,345km.

From going to Mercury to taking tourists on space rides, there is a lot to look forward to in 2018.

From Nasa's Trappist1 discovery to the mysterious Oumuamua – here are the biggest and most interesting space stories of the year.

Asteroids often collide with other objects as they hurtle through space, leaving their surfaces covered in various markings and craters.

From Nasa's ambitious goal to travel to Alpha Centauri to hunt for alien life to Russia's plan to open up a luxury hotel in space – these are the best space stories of the week.

Nasa reinvented a 150-year-old technique to capture supersonic motion as well as the shockwaves of a jet.

To simulate the failure, only two of the three parachutes bundled with the mock spacecraft were deployed.

Phaethon will come within 10 million kilometres of Earth and will be visible through small telescopes in areas with low light pollution.

"This was a fantastic way to end the year for SpaceX east coast launches," Jessica Jensen, director of SpaceX's Dragon Mission Management, said.

Kepler-90i is a scorching hot, rocky planet with an average temperature that is believed to exceed 800 degrees Fahrenheit.

The movie could be sent via SpaceX's Dragon capsule which will be heading towards space station Friday.
