An object 681 million light-years away might look like one glorious, exquisite mess, but there’s a lot more going on that a first glance indicates. The object showcased in a new Hubble image – called IC 2431 – is not one galaxy, but three, coming together in a massive galactic merger that will one day … Read more

The James Webb Space Telescope finished the first major stage in its long process of aligning the observatory’s 18-segmented primary mirror. A single star that the observatory looked at was deliberately rendered 18 times into a hexagonal shape. Eventually, those 18 images will perfectly align into a single, sharp focus, but the interim result portrays … Read more
A new telescope designed to peer into the twisted X-ray Universe has just sent back its first-ever imaging data. The Imaging X-Ray Polarimetry Explorer (IXPE), a joint project between NASA and the Italian Space Agency, fixed its gaze on one of the most famous explosions in the Milky Way: Cassiopeia A. Located 11,000 light-years … Read more
IXPE’s first science image shows the supernova remnant Cassiopeia A. (Image credit: NASA/CXC/SAO/IXPE) NASA’s newly-launched X-ray hunting probe has snapped its first science image and — wow — it’s spectacular. The Imaging X-ray Polarimetry Explorer (IXPE) probe launched Dec. 9, 2021, on a mission to observe objects like black holes and neutron stars in X-ray … Read more
The ongoing interaction between two galaxies 320 million light-years away has been captured in a gorgeous Hubble image. They’re collectively known as Arp 282 in Halton Arp’s Atlas of Peculiar Galaxies, and they consist of a large barred spiral galaxy named NGC 169, about 140,000 light-years across, and a much smaller polar-ring galaxy named IC … Read more
NASA engineers working to align the 18 hexagonal mirrors of the James Webb Space Telescope have released its first pictures. One shows the same star appearing 18 times, while a camera also took a ‘selfie’ of the mirrors Space 11 February 2022 By Leah Crane A selfie taken by a camera onboard the James Webb … Read more
Star light, star bright, the James Webb Space Telescope has seen its first star (though it wasn’t quite tonight) – and even taken a selfie, NASA announced Friday. The steps are part of the months-long process of aligning the observatory’s enormous golden mirror that astronomers hope will begin unraveling the mysteries of the early Universe … Read more
Astronomers across Africa and Europe have reacted with delight to news that Africa’s first millimetre-range radio telescope is to be built. The Africa Millimetre Telescope will fill a gap in the coverage of the Event Horizon Telescope (EHT), a global network of telescopes that can receive and analyse radio waves of around 1 millimetre in … Read more
