The Hubble Space Telescope has produced a time-lapse movie of a mysterious protostar that behaves like a flashing light.

The NASA/ESA Hubble Space Telescope - with a little help from an amateur astronomer - has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years away, practically a neighbour by cosmic standards, Messier 106 is one of the brightest and nearest spiral galaxies to our own.

ESA's XMM-Newton space observatory has completed the most detailed study ever of the fierce wind from a giant star, showing for the first time that it is not a uniform breeze but is fragmented into hundreds of thousands of pieces.

Astronomers using Herschel have found heavy molecular hydrogen in the protoplanetary disc around nearby star TW Hydrae. The observations enabled an estimate of the gaseous disc's mass, which is equivalent to 50 Jupiters.

Monitoring a pulsar with XMM-Newton, astronomers discovered X-ray variations that mimic in reverse similar changes seen in radio waves. This switching behaviour, which occurs within only a few seconds, challenges the current understanding of pulsars.

NASA has officially joined ESA's Euclid mission, a space telescope designed to investigate the mysterious natures of dark matter and dark energy.

Nearly 200 000 light-years from Earth, in the Large Magellanic Cloud, newly formed stars light up gas clouds in a riot of colours, visible in this image from the Hubble Space Telescope.

How fast people age may have more to do with their lifestyle than with how old they actually are. A new study with the Hubble Space Telescope reveals that the same is true of star clusters.

The NASA/ESA Hubble Space Telescope celebrates the holiday season with a striking image of the planetary nebula NGC 5189. The intricate structure of the stellar eruption looks like a giant and brightly coloured ribbon in space.

Astronomers using the NASA/ESA Hubble Space Telescope have uncovered seven primitive galaxies from a distant population that formed more than 13 billion years ago. In the process, their observations have put forward a candidate for the record for the most distant galaxy found to date (at redshift 11.9), and have shed new light on the earliest...

Studying the Andromeda galaxy with XMM-Newton, astronomers have discovered a black hole accreting mass at very high rate. This allowed them to study the link between disc and jets around a black hole at the peak of its accretion activity.

Bright pink nebulae almost completely encircle a spiral galaxy in this NASA/ESA Hubble Space Telescope image of NGC 922. The ring structure and the galaxy's distorted spiral shape result from a smaller galaxy scoring a cosmic bullseye, hitting the centre of NGC 922 some 330 million years ago.

The largest census of starburst galaxies, with almost 800 redshift measurements, has been assembled using data from Herschel and Keck. The survey confirms the important role of starbursts in the history of the Universe's star formation.

Astronomers using Herschel have detected massive debris discs around two nearby stars hosting low-mass planets. The discovery suggests that debris discs may survive more easily in planetary systems without very massive planets.

Astronomers have discovered a 'bridge' of hot gas connecting the galaxy clusters Abell 399 and 401. At least part of this gas might derive from the warm-hot intergalactic medium - the elusive web of gaseous filaments pervading the Universe.

The European Space Agency (ESA) solicits through the present Announcement of Opportunity (AO) proposals for the provision of the Archive Access Co-Ordination Unit (CU9) in the Gaia Data Processing and Analysis Consortium (DPAC). The deadline for proposal submission is 10 January 2013.

By combining the power of the NASA/ESA Hubble Space Telescope, NASA's Spitzer Space Telescope and one of nature's zoom lenses, astronomers have found what is probably the most distant galaxy yet seen in the Universe. The object offers a peek back into a time when the Universe was only 3 percent of its present age of 13.7 billion years.

Data from INTEGRAL and XMM-Newton have helped astronomers study how neutron stars accrete mass in highly obscured X-ray binaries. The results suggest a new method to estimate the mass of neutron stars.

Astronomers using the NASA/ESA Hubble Space Telescope have obtained a remarkable new view of a whopper of an elliptical galaxy, with a core bigger than any seen before. There are two intriguing explanations for the puffed up core, both related to the action of one or more black holes, and the researchers have not yet been able to determine which...
