Lee and the PHANGS-JWST TeamĪ delicate tracery of dust and bright star clusters threads across this image from the James Webb Space Telescope. Hubble investigated the aftermath of the supernova SN 2015ap during two different observing programmes, both designed to comb through the debris left by supernovae explosions in order to better understand these energetic events.Credits: ESA/Webb, NASA & CSA, J. A network of automatic robotic telescopes are spread across the globe, operated by both professional and amateur astronomers, and, without human intervention, reveal short-lived astronomical phenomena such as wandering asteroids, gravitational microlensing, or supernovae. IC 1776 recently played host to a catastrophically violent explosion - a supernova - which was discovered in 2015 by the Lick Observatory Supernova Search, a robotic telescope which scours the night sky in search of transient phenomena such as supernovae. This galaxy lies over 150 million light-years from Earth in the constellation Pisces. This simply means that, when …Ĥ September 2023: The swirls of the galaxy IC 1776 stand in splendid isolation in this image from the NASA/ESA Hubble Space Telescope. Both the galaxies are of a type known as emission-line galaxies. These hefty names do not lend themselves to easy memorisation, but they do actually contain valuable information: they are coordinates in the right ascension and declination system used widely by astronomers to locate astronomical objects. The rightmost galaxy, meanwhile, is known as 2MASX J21080362-3313196. The wonderful quality of this image also reveals several further galaxies, not associated with this system but fortuitously positioned in such a way that they appear to be forming a line that approaches the leftmost (in this image) component of Arp-Madore 2105-332, which is known individually as 2MASX J21080752-3314337. Like other recent Hubble Pictures of the Week, this system belongs to the Arp-Madore catalogue of peculiar galaxies. These are differentiated from one another by their spectra - the pattern …ġ1 December 2023: This image features an interacting galaxy system known as Arp-Madore 2105-332, that lies about 200 million light-years from Earth in the constellation Microscopium. In the case of Seyfert galaxies, the predominant subcategories are Type-1 and Type-2. There are further subclasses of both Seyfert galaxies and quasars. Whilst the precise categorisation of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby ones where the host galaxy remains plainly detectable alongside its central AGN, while quasars are invariably very distant AGNs whose incredible luminosities outshine their host galaxies. Seyfert galaxies host one of the most common subclasses of AGN, alongside quasars. Even more specifically, it is categorised as a Type-2 Seyfert galaxy. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core, known as an active galactic nucleus (AGN), so it is referred to as an active galaxy. 18 December 2023: This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth.
