New mass map of a distant galaxy cluster is the most precise yet [heic1416] 24 July 2014 Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing programme, the map shows the amount and distribution of mass within MCS J0416.1-2403, a massive galaxy cluster. Read more

Hubble traces the halo of a galaxy more accurately than ever before [heic1415] 21 July 2014 Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. Read more

Merging galaxies and droplets of starbirth [heic1414] 10 July 2014 The Universe is filled with objects springing to life, evolving and dying explosive deaths. This new image from the NASA/ESA Hubble Space Telescope captures a snapshot of some of this cosmic movement. Read more

Swiftly moving gas streamer eclipses supermassive black hole [heic1413] 19 June 2014 Astronomers have discovered strange and unexpected behaviour around the supermassive black hole at the heart of the galaxy NGC 5548. The international team of researchers detected a clumpy gas stream flowing quickly outwards and blocking 90 percent of the X-rays emitted by the black hole. Read more

Small but significant - Astronomers use Hubble to study bursts of star formation in the dwarf galaxies of the early Universe [heic1412] 19 June 2014 They may only be little, but they pack a star-forming punch: new observations from the NASA/ESA Hubble Space Telescope show that starbursts in dwarf galaxies played a bigger role than expected in the early history of the Universe.
