ESA has given the go-ahead for its Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) mission to progress from the study phase to the implementation phase, with an industrial contractor to build the spacecraft to be chosen in mid-2021.

A short burst of gamma rays 5.47 billion light years from Earth caused by the collision of two neutron stars that put out more energy in a half-second than the Sun could in 10 billion years has revealed the truth about luminous infrared kilonova.

By analyzing data from radar and optical telescopes, scientists have given radar the ability to make observations of meteors that burn up in the Earth's atmosphere that have previously only possible using optical telescopes.

After a long road featuring uncrewed test flights, launchpad explosions, parachute tests and finally crewed test flights, NASA has now officially certified SpaceX’s spacecraft system for transporting humans to the International Space Station (ISS).

Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today than it was 10 billion years ago, thanks to the evolution of galaxies and clusters.

Jupiter’s moon Europa is a fascinating world, with a global subsurface ocean encased in an icy shell and plumes of water that vent into space. A new study has simulated how these plumes might originate, revealing a surprisingly dynamic ice ball.

An independent review board has issued a report saying that NASA is capable of carrying out its Mars Sample Return (MSR) campaign that involves a series of missions to collect pristine samples from the Red Planet and return them to Earth.

Scientists in Europe and Hawaii have scored a world's first by detecting a "super-planet," also known as a cold brown dwarf, using a radio telescope. Located 212 light-years away, BDR J1750+3809 may help in the search for habitable exoplanets.

Giving a new meaning to the word "moonshine," NASA scientists at the Jet Propulsion Laboratory (JPL) in Pasadena, California, have concluded that Jupiter's moon Europa glows in the dark due to being constantly bombarded with high-energy radiation.

A serious-looking consortium of businesses is trying to position Japan as the first Asian space tourism hub, by proposing a futuristic, floating "Spaceport Japan" from which services like Virgin Galactic can operate their sub-orbital joyrides.

Rocket Lab is set to take an important step forward in its mission to reuse parts of its Electron booster, announcing that it will make its first attempt to recover the rocket’s first stage during a mission scheduled for later this month.

There are worlds out there so weird they’d put Dr. Who writers to shame. The latest to join the ranks is K2-141b, a scorching planet where it rains rocks, winds whip at supersonic speeds and huge swaths of the surface are covered in lava oceans.
