Active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious […]

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 […]

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 […]

Two galaxies are squaring off in Virgo and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. This is because galaxies are […]

Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds — mostly. On the third night of returning to same peaks, though, […]

Comet C/2022E3 (ZTF) is no longer too dim to require a telescope for viewing. By January 19, it could just be seen with the naked eye in this rural sky […]

The two dominant galaxies near center are far far away, 12 million light-years distant toward the northern constellation of the Great Bear. On the right, with grand spiral arms and […]

A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker – The Seagull Nebula. Using narrowband image data, this […]

Gravitational lensing by the galaxy cluster MACS0647 — in which the massive foreground cluster distorts and lenses the light emitted by distant background galaxies along the line of sight — […]

Our Moon doesn’t really look like this. Earth’s Moon, Luna, doesn’t naturally show this rich texture, and its colors are more subtle. But this digital creation is based on reality. […]
