Three new ultra-faint dwarf galaxies discovered

Using the Hubble Space Telescope (HST), astronomers have detected three new ultra-faint dwarf galaxies associated with the nearby spiral galaxy NGC 253. The newly found dwarfs turn out to be among the faintest systems so ...

Hubble takes a spiral snapshot

The luminous heart of the galaxy M61 dominates this image, framed by its winding spiral arms threaded with dark tendrils of dust. As well as the usual bright bands of stars, the spiral arms of M61 are studded with ruby-red ...

Nanoantennas help detectors see more heat, less noise

Sandia National Laboratories researchers have developed tiny, gold antennas to help cameras and sensors that "see" heat deliver clearer pictures of thermal infrared radiation for everything from stars and galaxies to people, ...

'New views of Jupiter' showcases swirling clouds on giant planet

Members of NASA's Juno mission team, some of the world's leading observers of Jupiter, and citizen scientists from across the globe will attend a workshop 'New Views of Jupiter: Pro-Am Collaborations during and beyond the ...

Team maps gas emissions from comet 67P/Churyumov-Gerasimenko

The European Space Agency's Rosetta spacecraft began orbiting comet 67P/Churyumov-Gerasimenko in August 2014, providing the closest and most detailed look at a comet to date. Now, a team led by astronomers at the University ...

Astronomers teach a machine to analyse galaxy images

A team of astronomers and computer scientists at the University of Hertfordshire have taught a machine to 'see' astronomical images. The technique, which uses a form of artificial intelligence called unsupervised machine ...
