The first identified compact galaxy group, Stephan's Quintet is featured in this stunning image from the newly upgraded Hubble Space Telescope. About 300 million light-years away, only four galaxies of the group are actually locked in a cosmic dance of repeated close encounters. The odd man out is easy to spot, though.

Spitzer s Orion

It is the tallest rocket in active use. The Delta IV Heavy is the largest of the Delta series, packing the punch of three rocket boosters instead of the usual one. The resulting rocket...

A Picturesque Venus Transit
16.10.2011

The rare transit of Venus across the face of the Sun in 2004 was one of the better-photographed events in sky history. Both scientific and artistic images flooded in from the areas that could see the transit: Europe and much of Asia, Africa, and North America.

The Eagle and The Swan

Webb s Southern Ring Nebula
14.07.2022

Cataloged as NGC 3132 the Southern Ring Nebula is a planetary nebula, the death shroud of a dying sun-like star some 2,500 light-years from Earth. Composed of gas and dust the stunning cosmic landscape is nearly half a light-year in diameter, explored in unprecedented detail by the James Webb Space Telescope.
