Comet ZTF may become visible to the unaided eye. Discovered early last year, this massive snowball has been brightening as it approaches the Sun and the Earth. C/2022 E3 (ZTF) will be closest...

APOD: 2023 February 19 Б Seven Dusty Sisters in Infrared
19.02.2023

Is this really the famous Pleiades star cluster? Known for its iconic blue stars, the Pleiades is shown here in infrared light where the surrounding dust outshines the stars. Here three infrared colors have been mapped into visual colors (R=24, G=12, B=4.6 microns).

APOD: 2025 December 2 Б M77: Spiral Galaxy with an Active Center
2.12.2025

What's happening in the center of nearby spiral galaxy M77? The face-on galaxy lies a mere 47 million light-years away toward the constellation of the Sea Monster (Cetus). At that estimated distance, this gorgeous island universe is about 100 thousand light-years across.

Neptune's Great Dark Spot: Gone But Not Forgotten

When NASA's Voyager 2 spacecraft flew by distant Neptune in August of 1989, astronomers were shocked. Since Neptune receives only 3 percent the sunlight Jupiter does, they expected to find a dormant, dark, frigid planet. Instead, the Voyager images revealed evidence of a dynamic and turbulent world.

Spiral Galaxy NGC 253
21.01.1999

A camera with over 67 million pixels (digital picture elements) was used to record this stunning image of spiral galaxy NGC 253. Known as the Wide Field Imager (WFI), the camera is the latest instrument to be installed at the European Southern Observatory's 2.2 meter telescope in La Silla, Chile.

X Ray Portrait of Trumpler 14
