New images from the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express spacecraft show an impact crater in the northern lowlands of Mars. Known...
Dark matter is a mysterious substance that makes up about 85% of the matter in the Universe. It does not emit any kind of electromagnetic radiation and...
A young star in the midst of a dramatic growth phase has been observed with the help of ESA’s Gaia satellite and NASA’s Near-Earth Object Wide-field...
Extrasolar ‘Neptunes’ are exoplanets with masses and radii similar to those of the ice giants in the Solar System. In 2015, astronomers using the NASA/ESA...
A new image from the NASA/ESA Hubble Space Telescope shows the core and the innermost parts of the spiral arms of a galaxy called Messier 100.
