The International Space Station (ISS) has been mankind’s farthest outpost since the turn of the century. Piers Bizony looks back at the history of its construction.
Observations of hot, Jupiter-like exoplanets using the Hubble and Spitzer space telescopes may have enabled astronomers to solve a longstanding mystery of missing water on the planets' surfaces.
A heliacal rising or an alignment of planets? Nigel Henbest explores this enduring mystery.
Jupiter's Great Red Spot continues to be something of a mystery for astronomers, but now a similar sized storm has been observed on a star.
New Dawn evidence suggests the spots stem from a subsurface layer of salt ice that sublimates away when it is exposed by an asteroid strike, leaving behind a salty residue.
The discovery of a cradle of young, monstrous galaxies is allowing astronomers to study more closely their relationship with dark matter structures.
The Juno space probe will use amateur observations to help plan its mission and keep track of Jupiter's constantly changing cloud layer.
Researchers have been comparing the flares released by our Sun with those released by a star elsewhere in the Milky Way, indicating it is possible the Sun has the potential to release superflares that would be devastating for life on Earth.
Researchers have suggested that an exoplanet in a distant orbit around its star could have been expelled from its planetary system, and may provide evidence for a similar process occurring in our own early Solar System.
Computer simulations have taken scientists one step closer to understanding the mysterious weather patterns on Jupiter.
The discovery of a supermassive blackhole in a nearby galaxy has presented astronomers with the opportunity of observing it swallowing a star and emitting jets of material, confirming current theories.
Mars’s moon Phobos is being pulled towards its host in a process that could eventually tear it apart and create rings around the Red Planet.
BBC Sky at Night Magazine's Dr Elizabeth Pearson explores the origins, legacy and future of this remarkable research.
Simulations of the behaviour of dark matter have hypothesized dark matter 'hairs' protruding from planetary bodies that could potentially be studied to reveal more about the mysterious substance.
Astronomers have undertaken a study to measure the distances to planetary nebulae with more accuracy than ever before.
Observations of a cool, red dwarf star that is producing an intensely powerful magnetic field could have major implications for the search for habitable planets outside our Solar System.
Astronomers have used ESO’s Very Large Telescope (VLT) to study the remains of a white dwarf and the asteroid it ripped apart in detail.
The earliest massive galaxies ever observed have been discovered by a team using data from a five-year survey of the Universe by ESO's VISTA telescope.
Measuring the 'pulse' of shimmering stars in a galaxy could provide a new method of determining that galaxy's age, according to a team of researchers.
BBC Sky at Night Magazine editor Chris Bramley was recently asked by Air Charter Service to select his favourite image of Earth from space.
