The confirmation of oxygen at 67P Churyumov-Gerasimenko is the first in situ detection of the gas at a comet, and has the potential to throw some models of the formation of the Solar System into question.
Observations using ESO's VISTA telescope have uncovered a previously unknown disc of young stars hiding behind dust clouds in the centre of the Milky Way.
The sources of highly energetic particles that surround black holes known as coronas could be linked to the production of massive flares of X-ray light that shoot out from black holes, according to new observations by the Swift and NuSTAR telescopes.
A long-standing question as to why Mars is so much smaller than Earth may have been solved with a new study looking at theories of planetary formation.
Cassini's next mission manoeuvre aims to find out more about the geological activity occurring on Saturn's icy moon Enceladus, revealing new data that will help determine the prospects for supporting life in its global ocean.
A study using Hubble Space Telescope data has allowed astronomers to peer into the early beginnings of the Universe, including the mysterious period known as the 'epoch of reionisation'.
Observations of a black hole tearing apart a nearby star are giving astronomers a rare insight into the process, known as a 'tidal disruption'.
NASA's Kepler 2 spacecraft may have found the "smoking gun" showing for the first time how white dwarfs can vaporise rocky remnants that survive within the dead star's planetary system.
The vast majority of Earth-like planets that will ever form in the Universe have yet to be born, according to a new study.
Scientists are looking to volcanic processes to explain a mineralogical anomaly in a mound within an impact basin near the Moon's south pole.
A unique observing opportunity has allowed two teams of researchers to discover blast waves occuring within the solar atmosphere.
Astronomers are still trying to solve the mystery of wave-like ripples discovered in the dusty disc of a nearby young star.
A team has used light data to calculate the mass of a supermassive black hole, with unexpected results.
NASA observations of Mars continue to throw up new revelations regarding the history of water on the Red Planet.
Rosetta data has revealed the secrets of comet 67P's darker, southern hemisphere for the first time.
The measurement of the mass of stars and other objects in space depends largely on observing their gravitational effect on their cosmic neighbours. But what if that object is alone in space? Scientists have developed a new method to determine the mass of pulsars that could solve this problem.
For the first time, NASA scientists have revealed that liquid water is currently present on the Red Planet.
The shape of Comet 67P/Churyumov-Gerasimenko was formed through the collision of two comets in the early Solar System, according to Rosetta scientists.
From the October issue onwards, your monthly Bonus Content is available exclusively online.
Data from the Rosetta spacecraft continues to reveal information about the nature of comets. The latest study shows a repeated ice-gas cycle occuring on and around the surface of 67P that keeps the comet 'alive'.
