Eta Carinae is a complex binary system, at a distance of around 8000 light years, with a large nebulosity surrounding the central objects. Observations with INTEGRAL have confirmed the nature of hard X-ray emission from the region to be from inverse compton scattered photons accelerated in a region where two stellar winds collide.

Astronomers using the NASA/ESA Hubble Space Telescope have compiled a large catalogue of gravitational lenses in the distant Universe. The catalogue contains a staggering 67 new gravitationally lensed images found around massive elliptical and lenticular-shaped galaxies.

Discovered in images taken with the Hubble Space Telescope's Advanced Camera for Surveys the gravitational lens system SDSSJ0946+1006 displays a unique double Einstein ring due to a fortuitous aligning of two distant galaxies and a foreground elliptical galaxy.

The Hubble Space Telescope's Advanced Camera for Surveys has resolved mysterious "blue blobs" in a structure called Arp's Loop between the galaxies M81 and M82 and and found them to be brilliant blue clusters of stars born in the gas swirls and eddies induced by a galactic interaction 200 million years ago.

The nearby transiting planet HD 189733b has been observed during three transits with Hubble's ACS in spectroscopic mode. Study of the data has provided strong evidence for the presence of a high level haze layer on this Jupiter-sized exoplanet.

The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much...
