The Universe consists mostly of the unknown substances dark matter and dark energy, but what exactly are they?

The Gaia satellite has spotted a unique binary star system that could help scientists learn more about Type Ia supernovae and the expansion of the Universe.

Our Sun may once have been part of a binary system, according to a study that suggests all Sun-like stars are born in pairs.

Apollo 11 astronaut's ShareSpace Foundation rolls out a 'red carpet for the Red Planet'.

NASA studies of a Martian volcano have revealed it ran dry just as the dominant species on Earth was facing catastrophe.

Heavy rain may have altered the surface of Mars, carving channels into its rock that we can see today, according to a new study.

What was previously thought to be a brown dwarf has been discovered to be an exoplanet lying on the cusp between the two. The exoplanet could help in the study of exoplanet atmospheres.

Data from ESA's Rosetta mission is still being analysed by scientists to make new discoveries about the structure and chemistry of comets. A new study has shown how comets could be producing oxygen via chemical reactions on their surface.

Studies of a young planetary system 10 lightyears away have revealed it is remarkably like our own.

An asteroid the size of Gibraltar passed by the Earth on 19 April, and will continue to grow in brightness for several nights giving a fantastic observing opportunity.

Jupiter may have been hiding a second great spot for over a thousand years. New images from the Very Large Telescope have revealed a colossal Great Cold Spot, a cool patch in the planet’s polar atmosphere that appears to be created by the planet’s aurora.

Gravitational lensing has allowed astronomers to spy on a 'typical' galaxy as it was in the days of the early Universe. This find will allow them to study the most numerous kind of fledgling galaxy present during this highly important era.

The remnants of a collision between two infant stars has been captured by ALMA. The beautiful images could help astronomers understand how such stellar crashes govern the rate at which our Galaxy forms stars.

By heating gas to millions of degrees and compressing it to huge densities, a team of scientists have been able to study the nuclear reactions that occur in a stellar core.

The Sun's activity may be generating a transient atmosphere on dwarf planet Ceres, say NASA scientists.

An atmosphere has been detected for the first time around a planet with a mass and radius similar to Earth.

Mars once had an atmosphere and running water, but that all changed as a result of the power of our Sun, according to new NASA data.
