ESA's Planck satellite has revealed that the first stars in the Universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the only sources needed to account for reionising atoms in the cosmos, having completed half of this process when the Universe...

A giant bubble surrounding the centre of the Milky Way shows that six million years ago our Galaxy's supermassive black hole was ablaze with furious energy. It also shines a light on the hiding place of the Galaxy's so-called 'missing' matter.

In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.

Since its launch in December 2013 Gaia has been sweeping the skies mapping around one billion stars. The data collected will allow astronomers to probe the very nature of the astronomical objects observed by the spacecraft. But before the data can be useful to the scientific community they must pass through a complex and robust processing...

Proposals are solicited for observations with XMM-Newton in response to the sixteenth Announcement of Opportunity, AO-16, issued 23 August 2016. This AO covers the period May 2017 to April 2018 and is open to proposers from all over the world. The deadline for proposals is 7 October 2016 (12:00 UT).

Operating in the depths of space, far beyond the Moon's orbit, ESA's Gaia spacecraft has now completed two years of a planned five-year survey of the sky. Despite a series of unexpected technical challenges, the mission is on track to complete the most detailed and complex mapping of the heavens ever undertaken.

Detailed analysis of data collected by Rosetta show that comets are the ancient leftovers of early Solar System formation, and not younger fragments resulting from subsequent collisions between other, larger bodies.

Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space, have discovered the system AR Scorpii to be a new type of exotic binary star.

Fifty years ago Captain Kirk and the crew of the starship Enterprise began their journey into space – the final frontier. Now, as the newest Star Trek film hits cinemas, the NASA/ESA Hubble space telescope is also exploring new frontiers, observing distant galaxies in the galaxy cluster Abell S1063 as part of the Frontier Fields programme.

Using observations from ESA's Venus Express satellite, scientists have shown for the first time how weather patterns seen in Venus' thick cloud layers are directly linked to the topography of the surface below. Rather than acting as a barrier to our observations, Venus' clouds may offer insight into what lies beneath.

Last week, 80 European teachers had the opportunity to attend a special workshop that highlighted the major areas of space science and technology. These teachers now have an important mission - to bring this information back into the classroom, where it will help them teach and inspire the next generation of scientists and engineers across Europe.

ESA's orbiting X-ray observatory, XMM-Newton, has proved the existence of a 'gravitational vortex' around a black hole. The discovery, aided by NASA's NuSTAR mission, solves a mystery that has eluded astronomers for more than 30 years and will allow them to map the behaviour of matter very close to black holes.

This new NASA/ESA Hubble Space Telescope image reveals the beating heart of one of the most visually appealing, and most studied, supernova remnants known – the Crab Nebula. At the centre of this nebula the spinning core of a deceased star breathes life into the gas that surrounds it.

Earth's atmosphere is leaking. Every day, around 90 tonnes of material escapes from our planet's upper atmosphere and streams out into space. Although missions such as ESA's Cluster fleet have long been investigating this leakage, there are still many open questions.

With its very first observation, the Hitomi X-ray observatory has discovered that the gas in the Perseus cluster of galaxies is much less turbulent than expected. This is a surprise because the Perseus cluster is home to NGC 1275, a highly energetic active galaxy.

ESA's billion-star surveyor Gaia, launched on 19 December 2013, and in routine science operations since 25 July 2014, will release the first mission data on 14 September 2016.

Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras – stunning light shows in a planet's atmosphere – on the poles of the largest planet in the Solar System, Jupiter. This observation programme is supported by measurements made by NASA's Juno spacecraft, currently on its way to Jupiter.

Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September.

This new image from the NASA/ESA Hubble Space Telescope shows a cosmic tadpole, with its bright head and elongated tail, wriggling through the inky black pool of space. Tadpole galaxies are rare and difficult to find in the local Universe. This striking example, named LEDA 36252, was explored as part of a Hubble study into their mysterious...
