This new image of powerful remnants of dead stars and their mighty action on the surrounding gas from ESA's XMM-Newton X-ray observatory reveals some of the most intense processes taking place at the centre of our galaxy, the Milky Way.

Extreme thermal stresses experienced by a comet as it orbits around the Sun could explain the extensive fracturing thought to drive its long-term surface erosion, say Rosetta scientists analysing high-resolution images of Comet 67P/Churyumov-Gerasimenko's surface.

ESA's Rosetta today witnessed Comet 67P/Churyumov-Gerasimenko making its closest approach to the Sun. The exact moment of perihelion occurred at 02:03 GMT this morning when the comet came within 186 million km of the Sun.

In the approach to perihelion over the past few weeks, Rosetta has been witnessing growing activity from Comet 67P/Churyumov-Gerasimenko, with one dramatic outburst event proving so powerful that it even pushed away the incoming solar wind.

Complex molecules that could be key building blocks of life, the daily rise and fall of temperature, and an assessment of the surface properties and internal structure of the comet are just some of the highlights of the first scientific analysis of the data returned by Rosetta's lander Philae last November.

Some of the most breathtaking views in the Universe are created by nebulae – hot, glowing clouds of gas. This new NASA/ESA Hubble Space Telescope image shows the centre of the Lagoon Nebula, an object with a deceptively tranquil name.

ESA is organising a training workshop for science teachers in association with the Galileo Teacher Training Programme (GTTP). The sixth ESA/GTTP Teacher Training Workshop will be held at the European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands, between 23 and 27 November, 2015. The deadline for receipt of...

Rosetta's investigations of its comet are continuing as the mission teams count down the last month to perihelion – the closest point to the Sun along the comet's orbit – when the comet's activity is expected to be at its highest.

The ghostly shells of galaxy ESO 381-12 are captured here in a new image from the NASA/ESA Hubble Space Telescope, set against a backdrop of distant galaxies. The strikingly uneven structure and the clusters of stars that orbit around the galaxy suggest that ESO 381-12 may have been part of a dramatic collision sometime in its relatively recent...

ESA's Planck mission is the source for a new catalogue, eagerly awaited by the scientific community, and available online from today. The Second Planck Catalogue of Compact Sources uses data from the entire mission to identify tens of thousands of compact sources, as well as providing polarisation data for several hundred of them.

This image, based on housekeeping data from ESA's Gaia satellite, is no ordinary depiction of the heavens. While the image portrays the outline of our Galaxy, the Milky Way, and of its neighbouring Magellanic Clouds, it was obtained in a rather unusual way.
