Spiral Galaxy Messier 98

This newly released image shows spiral galaxy Messier 98, which is located about 50 million light-years away. The color blue has many associations — coldness, sadness, serenity. However, the color holds a completely different meaning for astronomers, as demonstrated by the edge-on spiral galaxy Messier 98. Messier 98, also known as NGC 4192, is located […]

Planet Proxima b

In this six minute ESOcast video astronomers discuss the newly discovered Proxima b and the possibility of life outside our solar system. The Pale Red Dot campaign aimed to find a planet orbiting our nearest stellar neighbor, Proxima Centauri. Incredibly, the quest succeeded and the team did indeed find a planet. Even more excitingly, the […]

Planet Found in Habitable Zone Around Nearest Star

Scientists reveal that a newly discovered, roughly Earth-sized planet orbiting our nearest neighboring star might be habitable. Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and […]

Water Snowline Around Young Star V883 Orionis

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers has made the first ever resolved observation of a water snow line within a protoplanetary disc. This line marks where the temperature in the disc surrounding a young star drops sufficiently low for snow to form. A dramatic increase in the brightness of the […]

Unexpected Excess of Giant Planets in Star Cluster Messier 67

A team of astronomers reveals that there are far more planets of the hot Jupiter type than expected in star cluster Messier 67. The surprising discovery was obtained using a number of telescopes and instruments, among them the HARPS spectrograph at ESO’s La Silla Observatory in Chile. The denser environment in a cluster will cause […]

New ESO Image of the Colorful Emission Nebula LHA 120-N55

This newly released ESO image shows the glowing gas cloud LHA 120-N55 in the Large Magellanic Cloud. In this image from ESO’s Very Large Telescope (VLT), light from blazing blue stars energises the gas left over from the stars’ recent formation. The result is a strikingly colourful emission nebula, called LHA 120-N55, in which the […]

Astronomers View Wolf-Lundmark-Melotte Galaxy

This newly released image shows the Wolf-Lundmark-Melotte galaxy. This scene, captured by ESO’s OmegaCAM on the VLT Survey Telescope, shows a lonely galaxy known as Wolf-Lundmark-Melotte, or WLM for short. Although considered part of our Local Group of dozens of galaxies, WLM stands alone at the group’s outer edges as one of its most remote […]
