Volunteer citizen scientists have been helping NASA scientists get closer to geological features on the surface of Mars.
The Trace Gas Orbiter that is part of the ExoMars 2016 mission to study the Red Planet has arrived safely in orbit, but contact has not yet been made with the Schiaparelli lander.
In the first of a new series bringing the cosmos into the kitchen, amateur astronomer and baker Katharine Kilgour pays tribute to the gas giant Jupiter with some tasty shortbread treats.
Katharine Kilgour likes to combine her love of astronomy with her love of cooking, making tasty treats to feed herself, her friends and her family Astro-boy (aged 12), Astro-girl (aged 16) and Astro-dad.
More people have looked through Griffith Observatory’s 12-inch refracting Zeiss telescope in Los Angeles than through any other on Earth. Astrophotographer and writer Jamie Carter joins the throngs in the Hollywood hills.
Astronomers have used data from the Hubble Space Telescope to conclude that there are ten times as many galaxies in the Universe than we can currently observe.
Astronomers have spotted something never before seen in the Universe: a binary star system with three planet-forming discs surrounding it.
A 'hyperluminous X-ray source' has been identified as a massive black hole that may have wandered into another galaxy.
Astronomers have been studying a binary star system in the hope of explaining the source of balls of plasma seen firing out into space.
New to astronomy? Enter our competition for the chance to win one of five copies of a new introductory guide written by astronomers from the Royal Observatory Greenwich.
Dione could be the latest moon in our Solar System on which a subsurface ocean has been found, according to a new study.
Observations to explain why a star in our Galaxy is periodically dimming in brightness have added to the mystery behind its puzzling behaviour.
Mercury can be grouped together with Earth as another tectonically active planet in our Solar System, according to a study that used images captured by the MESSENGER space probe.
Observations using the Hubble Space Telescope may have revealed surprising activity in Europa's subsurface ocean, causing water vapour to erupt from its surface.
A study has calculated that Pluto could be hosting an ocean below its surface with a salt content similar to the Dead Sea on Earth.
Astronomers have been able to discover an exoplanet orbiting two suns by observing how its mass warps spacetime.
Astronomers believe they may have solved the mystery behind a huge, bright cloud of gas found 11.5 billion lightyears away.
New discoveries of ancient lakes and valleys on the Red Planet are helping scientists uncover the story of water on Mars, and whether microbial life could once have existed.
Astronomers using the Hubble Space Telescope have been able to observe a key stage in the evolution of a star in real time.
Quasars are thought to be some of the first light sources to have formed in the Universe, but finding ancient specimens to study is a tricky task. A team of astronomers has found a batch of specimens that nearly doubles the amount of ancient quasars that we know of.
