Magellanic Clouds duo may have been a trio
Two of the closest galaxies to the Milky Way -- the Large and Small Magellanic Clouds -- may have had a third companion, astronomers believe. New research describes how another 'luminous' galaxy was likely engulfed by the Large Magellanic Cloud some three to five billion years ago.

BUFFALO charges towards the earliest galaxies
The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it.

Stunning details of spiral galaxy NGC 3981
FORS2, an instrument mounted on ESO's Very Large Telescope, has observed the spiral galaxy NGC 3981 in all its glory. The image was captured as part of the ESO Cosmic Gems Programme, which makes use of the rare occasions when observing conditions are not suitable for gathering scientific data.

Galactic 'wind' stifling star formation is most distant yet seen
For the first time, a powerful 'wind' of molecules has been detected in a galaxy located 12 billion light-years away. Probing a time when the universe was less than 10 percent of its current age, astronomers sheds light on how the earliest galaxies regulated the birth of stars to keep from blowing themselves apart.

New exoplanet found very close to its star
Using data from NASA's Kepler Space Telescope, an international team has discovered a new exoplanet twice the size of Earth. It orbits its star every six days and is thus very close to it, about 10 times closer than Mercury is to the Sun.

Saturn's famous hexagon may tower above the clouds
The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn's clouds.

Radio observations confirm superfast jet of material from neutron star merger
The supersharp radio 'vision' of a continent-wide collection of radio telescopes has answered an outstanding question about the aftermath of a merger of two neutron stars.

Telescope maps cosmic rays in Large and Small Magellanic Clouds
A radio telescope in outback Western Australia has been used to observe radiation from cosmic rays in two neighbouring galaxies, showing areas of star formation and echoes of past supernovae.

Veiled supernovae provide clue to stellar evolution
At the end of its life, a red supergiant star explodes in a hydrogen-rich supernova. By comparing observation results to simulation models, an international research team found that in many cases this explosion takes place inside a thick cloud of circumstellar matter shrouding the star. This result completely changes our understanding of the last stage of stellar evolution.
