The current darling of the northern night, Comet C/2022 E3 ZTF is captured in this telescopic image from a dark sky location at June Lake, California. Of course Comet ZTF has been growing brighter in recent days, headed for its closest approach to Earth on February 1. But this view was recorded on January 23, […]

Active galaxy NGC 1275, the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies, is a mysterious object. Wild-looking at visible wavelengths, the active galaxy is a prodigious source of x-rays and radio emission as it accretes matter from entire galaxies. This Hubble Space Telescope image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long, that are held together by magnetic fields.

To some, the dark shape looks like a mythical boogeyman. Scientifically, Lynds’ Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. In contrast, the brighter reflection nebula vdB 62 is more easily seen just above and to the right of center in […]

If you could stand on exoplanet LHS 475 b, what might you see? No one knows for sure but pictured here is an interesting guess made by an Earth-based artificial intelligence (AI) engine. The existence of the exoplanet was indicated in data taken by the Earth-orbiting TESS satellite but confirmed and further investigated only this […]
