This edge-on viewpoint makes the galaxy’s disk appear as a sharp line through space, with its prominent dust lanes forming thick bands of clouds that obscure our view of the galaxy’s glow. If we could fly above the galaxy, viewing it from the top down, we would see this dust scattered across UGC 10043, possibly […]

Stumped by Space ORCs ORCs are faint extragalactic circles of radio emission that appear to be invisible at other wavelengths. As the number of known ORCs slowly climbs, researchers have begun to test possible formation mechanisms. Among the many possibilities are the jets of active galactic nuclei: luminous galactic centers powered by accreting supermassive black […]

A recent cosmic census has revealed an unexpected threefold rise in active black holes within dwarf galaxies, creating the most extensive database of intermediate-mass black holes recorded to date. This survey, conducted with the Dark Energy Spectroscopic Instrument (DESI) at the Mayall Telescope in Arizona, identified over 2,500 black holes in dwarf galaxies—more than triple […]
The Coma Cluster is a particularly rich cluster that contains over a thousand known galaxies. Amateur astronomers can easily spot several of these in a backyard telescope (See Caldwell 35). Most of them are elliptical galaxies, and that’s typical of a dense galaxy cluster like the Coma Cluster: many elliptical galaxies form through close encounters […]
The white or blueish spots are six images of the same quasar created by the lensing effect of two galaxies, one appearing as the light patch in the centre and one as a red arc F. Dux et al. A chance alignment between two massive galaxies could help astronomers better measure the expansion of the […]

Every day, invisible to the human eye, thousands of enigmatic flashes of cosmic energy known as fast radio bursts (FRBs) erupt across the sky, releasing as much energy in milliseconds as the sun does in a day. Thanks to their fleeting nature, scientists have often had to rely on luck just to observe FRBs, let […]
This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celestial lights. Like any spiral galaxy, shining stars fill its disk, giving the galaxy a beautiful glow. Along its two […]
