The press are calling C/2023 A3, ‘Comet of the century’ A slight exaggeration perhaps, but it is certainly the best we have seen since C/2020 F3 (NEOWISE) back in 2020. This is the view you get if you look towards the West for the next couple of weeks.

I am making a case, to myself, for the purchase of an Astrodon 3Nm OIII filter because I have other targets whose data could…
Back to the cosmological drawing board?
Image Credit: NASA, ESA, CSA, STScI, B. Robertson (UC Santa Cruz), B. Johnson (CfA), S. Tacchella (Cambridge), P. Cargile (CfA). Generally, we are all a nosy bunch. Since 1950 many people have loved being flies on the walls in Ambridge to hear the drama and gossip of several families in The Archers that don’t actually exist. The genealogical roots of many celebrities have been investigated with a fine tooth comb over the years in…

Multiple milestones in astronomy have reshaped our understanding of the universe: from Apollo 8’s Earthrise photo to Copernicus’ heliocentric model, Galileo’s observations, Hubble’s expanding universe, and Penrose’s cyclic cosmology theory….
