Rosetta's discovery marks the first 'in situ' detection of the gas at a comet
Thu Oct 29, 2015 9:58am

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.

Astronomers discover thin disc of young stars hidden behind dusty clouds
Wed Oct 28, 2015 3:25pm

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.

Mysterious sources of energetic particles could be the source of X-ray jets
Wed Oct 28, 2015 9:53am

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.

Planetary formation theory suggests why Red Planet is smaller than Earth
Tue Oct 27, 2015 10:43am

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.

Spacecraft to collect data on geological activity in moon's global ocean
Tue Oct 27, 2015 9:17am

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.

Astronomers peer into earliest Universe, before epoch of reionisation
Fri Oct 23, 2015 10:36am

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'.

Thu Oct 22, 2015 2:07pm

Observations of a black hole tearing apart a nearby star are giving astronomers a rare insight into the process, known as a 'tidal disruption'.

Kepler 2 discovers irregular transit occurring around distant dead star
Thu Oct 22, 2015 9:08am

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.

Hubble and Kepler data reveals planet-forming potential of the Universe
Wed Oct 21, 2015 9:49am

The vast majority of Earth-like planets that will ever form in the Universe have yet to be born, according to a new study.

Impact crater near Moon's south pole could have begun volcanic activity
Tue Oct 20, 2015 1:28pm

Scientists are looking to volcanic processes to explain a mineralogical anomaly in a mound within an impact basin near the Moon's south pole.

Rosetta data has revealed the secrets of comet 67P's darker, southern hemisphere for the first time.

New method enables scientists to measure the mass of solitary pulsars
Tue Oct 06, 2015 10:36am

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.
