Countless galaxies vie for attention in this dazzling image of the Fornax Cluster, some appearing only as pinpricks of light while others dominate the foreground. One of these is the lenticular galaxy NGC 1316. The turbulent past of this much-studied galaxy has left it with a delicate structure of loops, arcs and rings that astronomers have now imaged in greater detail than ever before with the VLT Survey Telescope. This image was processed with the VST-Tube data reduction program. Credit: ESO/A. Grado and L. Limatola

Artist’s impression of the hot massive supergiant Zeta Puppis. The rotation period of the star indicated by the new BRITE observations is 1.78 d, and its spin axis is inclined by (24 ± 9)° with respect to the line of sight. Credit: Tahina Ramiaramanantsoa

Astronomers recently discovered that spots on the surface of a supergiant star are driving huge spiral structures in its stellar wind. Massive stars are responsible for producing the heavy elements that make up all life on Earth. At the end of their lives they scatter the material into interstellar space in catastrophic explosions ie supernovae – without these dramatic events, our solar system would never have formed.

Zeta Puppis is an evolved massive star known as a ‘supergiant’...

For 3 decades, astronomers thought that only Saturn’s moon Janus confined the planet’s A ring – the largest and farthest of the visible rings. But after poring over NASA’s Cassini mission data, Cornell astronomers now conclude that the teamwork of seven moons keeps this ring corralled. Without forces to hold the A ring in check, the ring would keep spreading out and ultimately disappear...

Why does the universe favor matter over antimatter? The first glimpse of data from the full array of a deeply chilled particle detector operating beneath a mountain in Italy sets the most precise limits yet on where scientists might find a theorized process to help explain why there is more matter than antimatter in the universe. This new result is based on two months of data from the full detector of the CUORE (Cryogenic Underground Observatory for Rare Events) experiment at the Italian National Institute for Nuclear Physics’ (INFN’s) Gran Sasso National Laboratories (LNGS) in Italy. CUORE means “heart” in Italian.

CUORE is considered one of the most promising effo...
