The globular cluster Messier 107, also known as NGC 6171, is located about 21 000 light-years away in the constellation of Ophiuchus. Messier 107 is about 13 arcminutes across, which corresponds to about 80 light-years at its distance. As is typical of globular clusters, a population of thousands of old stars in Messier 107 is densely concentrated into a volume that is only about twenty times the distance between our Sun and its nearest stellar neighbour, Alpha Centauri, across. This image was created from exposures taken through blue, green and near-infrared filters, using the Wide Field Imager (WFI) on the MPG/ESO 2.2-metre telescope at La Silla Observatory, Chile.

This movie, made from data obtained by NASA's Cassini spacecraft, shows Saturn's southern aurora shimmering over approximately 20 hours as the planet rotates. This video is among the first videos released from a study that extracts auroral emissions out of the entire catalogue of images taken by Cassini's visual and infrared mapping spectrometer.

This pan sequence gives a closer view of a new VISTA image of the Tarantula Nebula in the Large Magellanic Cloud and the very rich surrounding area of sky. Many regions of star-formation, and many clusters of hot young stars are seen in great detail.

This infrared image, made with ESO’s VISTA survey telescope, is from the VISTA Magellanic Cloud Survey. The project will scan a vast area — 184 square degrees of the sky (corresponding to almost one thousand times the apparent area of the full Moon), including our nearby neighbouring galaxies the Large and Small Magellanic Clouds.

This pan shows many details in a gorgeous cosmic watercolour of the star-forming region around the star R Coronae Australis that was captured by the Wide Field Imager (WFI), on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory. Fine details of the bluish reflection nebula and the huge surrounding dust cloud are visible. This star-forming region is located some 420 light-years away in the small constellation of Corona Australis (the Southern Crown).

NGC 253 is one of the closest galaxies to our own. It is a bright spiral that lies about 13 million light-years from Earth in the southern constellation of Sculptor and is noted for being a starburst galaxy with very vigorous star formation and very dusty spiral arms. In the infrared, the rich dust clouds in the galaxy’s spiral arms become nearly transparent and a whole host of cool red stars that are otherwise invisible can be seen. The VISTA infrared images were taken through Y, Z, J, Ks and narrowband filters. The field of view is about 38 by 25 arcminutes.

For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves to the other side of its host star. The planet has the smallest orbit so far of all directly imaged exoplanets, lying as close to its host star as Saturn is to the Sun.

The team of astronomers used the NAOS-CONICA instrument (or NACO), mounted on one of the 8.2-metre Unit Telescopes of ESO's Very Large Telescope (VLT), to study the immediate surroundings of Beta Pictoris in 2003, 2008 and 2009. In 2003 a faint source inside the disc was seen, but it was not possible to exclude the remote possibility that it was a background star. In new images taken in 2008 and spring 2009 the source had disappeared! The most recent observations, taken during autumn 2009, revealed the object on the other side of the disc after having been hidden either behind or in front of the star. This confirmed that the source indeed was an exoplanet and that it was orbiting its host star. It also provided insights into the size of its orbit around the star.

The above composite shows the reflected light on the dust disc in the outer part, as observed in 1996 with the ADONIS instrument on ESO's 3.6-metre telescope. In the central part, the observations of the planet obtained in 2003 and autumn 2009 with NACO are shown. The possible orbit of the planet is also indicated, albeit with the inclination angle exaggerated.

This image of the nearby galaxy Messier 83 was taken in the infrared part of the spectrum with the HAWK-I instrument on ESO’s Very Large Telescope. The very fine image quality of this camera, coupled with the huge light-collecting power of the VLT, reveals vast numbers of stars within the galaxy. The images were taken in three different parts of the infrared spectrum and the total exposure time was eight and a half hours, split into more than five hundred exposures of one minute each. The field of view is about 13 arcminutes across.

This image, in the constellation of Vulpecula, shows an entire assembly line of newborn stars. The diffuse glow reveals the widespread cold reservoir of raw material that our Galaxy has in stock for building stars.

Infrared view of the Catâs Paw Nebula (NGC 6334) taken by VISTA. NGC 6334 is a vast region of star formation about 5500 light-years from Earth in the constellation of Scorpius. The whole gas cloud is about 50 light-years across. NGC 6334 is one of the most active nurseries of young massive stars in our galaxy, some nearly ten times the mass of our Sun and most born in the last few million years. The images were taken through Y, J and Ks filters (shown as blue, green and red respectively) and the exposure time was five minutes per filter. The field of view is about one degree across.
