The mission will look for signs of habitability on the Red Planet, and may answer some questions about how life on our own world began.
ESO's Very Large Telescope is enabling astronomers to view stellar activity in unpredecented clarity, revealing the secrets of stellar birth, evolution and death.
The detection of gravitational waves in space moves one step closer as LISA Pathfinder begins operations.
The Hubble Telescope continues to make groundbreaking discoveries that are expanding astronomers' understanding of the formation of the Universe.
New observations using the ALMA telescope have led to an important discovery about the growth of a young protostar.
The record-breaking NASA astronaut Scott Kelly has handed over command of the ISS following his return to Earth with cosmonauts Mikhail Kornienko and Sergey Volkov.
The 'empty' voids between filaments of dark matter and galaxies could be hiding as much as 20 per cent of the normal matter in the cosmos, according to a new study.
Observations of a type Ia supernova with the Hubble Space Telescope are revealing new information about the source of their brightness.
The news of the first ever detection of gravitational waves was a major astronomical discovery. Now a further study of the event has revealed a gamma-ray burst that could point to the origin of the black holes behind the event.
Data from New Horizons continues to enable NASA scientists to learn more about Pluto and its moons. The latest study suggests a subsurface ocean may once have existed on Charon.
The 'accidental' discovery of X-ray jets shooting out of a black hole in the distant Universe is a sign there could be more waiting to be detected.
Observations with the Hubble Space Telescope have enabled astronomers to measure the rotation rate of a ‘super Jupiter’ exoplanet by comparing the changes in brightness in its atmosphere.
A new method of analysis has enabled astronomers to analyse the gases in the atmosphere of a super-Earth.
Author and writer Jamie Carter presents an astronomer's holiday dream list: 10 hotels, guest houses, resorts and other trips with a focus on telescopes, stargazing, star parties and astrophotography.
A team astronomers discovered a supernova imposter that, oddly, was giving off a fierce amount of X-rays.
100 years after Einstein presented his theory of general relativity to the world, the presence of gravitational waves has been detected for the first time.
On 3 December 2015, ESA’s LISA Pathfinder lifted off from Kourou in French Guiana as part of a new mission to prepare for the future detection of gravitational waves. Astronomer and science writer Govert Schilling investigates.
