A Very Luminous Magnetar-Powered Supernova

ESO’s La Silla and Paranal Observatories have demonstrated for the first time a link between a very long-lasting burst of gamma rays and an unusually bright supernova explosion. The study reveals that the supernova following the burst GRB 111209A was not driven by radioactive decay, as expected, but was instead powered by the decaying super-strong […]

Giant Galaxy Messier 87 is Still Growing

June 25, 2015

0 Comments

The huge halo around giant elliptical galaxy Messier 87 appears on this very deep image. An excess of light in the top-right part of this halo, and the motion of planetary nebulae in the galaxy, are the last remaining signs of a medium-sized galaxy that recently collided with Messier 87.

The image also reveals many other galaxies forming the Virgo Cluster, of which Messier 87 is the largest member. In particular, the two galaxies at the top right of the frame are nicknamed "the Eyes".

According to new observations with ESO’s Very Large Telescope, the giant elliptical galaxy Messier 87 has swallowed an entire medium-sized galaxy over the last billion years. This is the first time a team of astronomers has been able to track the motions of 300 glowing planetary nebulae to find clear evidence of this event. They […]

VLT Discovers the Brightest Distant Galaxy to Date

Using ESO’s Very Large Telescope with help from the W. M. Keck Observatory, the Subaru Telescope and the NASA/ESA Hubble Space Telescope, a team of astronomers has discovered the brightest galaxy to date in the early Universe and discovered strong evidence that examples of the first generation of stars lurk within it. The newly found […]

New ESO Image of RCW 34

This newly released image from the European Southern Observatory shows the young star-forming region RCW 34. In the brightest region of this glowing nebula called RCW 34, gas is heated dramatically by young stars and expands through the surrounding cooler gas. Once the heated hydrogen reaches the borders of the gas cloud, it bursts outwards […]

Evidence for a Dark Side to NGC5128

Using data from ESO’s Very Large Telescope, astronomers have discovered a new class of “dark” globular star clusters around Centaurus A. These star clusters contain much more mass and may either harbor unexpected amounts of dark matter, or contain massive black holes. Globular star clusters are huge balls of thousands of stars that orbit most […]

ESO Image of Molecular Cloud LDN1774

This newly released image from the 2.2-meter MPG/ESO telescope shows the dark molecular cloud cataloged as LDN1774. Rather than showing spectacular objects, some of the most surprising images of the Universe instead focus on emptiness. This new image from the 2.2-meter MPG/ESO telescope shows dark tentacles swirling outwards from a dark, blank spot of space […]
