A now famous picture from the Hubble Space Telescope featured Pillars of Creation, star forming columns of cold gas and dust light-years long inside M16, the Eagle Nebula. This false-color composite image views...

NGC 2392: Double Shelled Planetary Nebula
15.02.2020

To some, this huge nebula resembles a person's head surrounded by a parka hood. In 1787, astronomer William Herschel discovered this unusual planetary nebula: NGC 2392. More recently, the Hubble Space Telescope imaged the nebula in visible light, while the nebula was also imaged in X-rays by the Chandra X-ray Observatory.

4.12.2022

Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as large and clear as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen with the unaided eye even from the depths of a light-polluted city.

IC443's Neutron Star
14.12.2000

Using x-ray data from the orbiting Chandra Observatory along with radio data from the Very Large Array, a team of researchers has discovered evidence for a new example of one of the most bizarre objects known to modern astrophysics -- a neutron star.

Centaurus A: Young Blue Star Stream
17.10.2002

Almost lost in this cosmic jumble of stars, gas and dust is a faint but definite blue arc -- a stream of young stars whose formation was probably triggered as a small dwarf galaxy was torn apart approaching the giant elliptical galaxy Centaurus A.

The Sharpest View of the Sun
13.11.2002

This stunning image shows remarkable and mysterious details near the dark central region of a planet-sized sunspot in one of the sharpest views ever of the surface of the Sun. Just released, the picture was made using the Swedish Solar Telescope now in its first year of operation on the Canary Island of La Palma.

Ringed Planet Uranus

Yes it does look like Saturn, but Saturn is one of only four giant ringed planets in our Solar System. And while Saturn has the brightest rings, this system of rings and moons actually belongs to planet Uranus, imaged here in near-infrared light by the Antu telescope at the ESO Parnal Observatory in Chile.

Probably a Planet for Beta Pic
27.11.2008

A mere 50 light-years away, young star Beta Pictoris became one of the most important stars in the sky in the early 1980s. Satellite and ground-based telescopic observations revealed the presence of a surrounding...

Cherenkov Telescope at Sunset
