Latest Very Large Telescope Stories
The presidents of Chile, Colombia, Mexico and Peru met today at ESO’s Paranal Observatory in the Atacama Desert of Chile, seeing first hand the state-of-the-art telescopes and technology of ESO’s flagship site.
By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away.
The strange galaxy Centaurus A is pictured in a new image from the European Southern Observatory (ESO). With a total exposure time of more than 50 hours this is probably the deepest view of this peculiar and spectacular object ever created.
A new image of Messier 55 from ESO's VISTA infrared survey telescope shows tens of thousands of stars crowded together like a swarm of bees.
A new image of the region surrounding the reflection nebula Messier 78, just to the north of Orion’s Belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls.
ESO's VISTA telescope has created the widest deep view of the sky ever made using infrared light. This new picture of an unremarkable patch of sky comes from the UltraVISTA survey and reveals more than 200 000 galaxies.
Looking at a few, very carefully selected galaxies, astronomers are conducting a survey to determine how these galaxies grew during their “teenage” years.
Astronomers have known for some time that the earliest galaxies were much smaller than the impressive spiral and elliptical galaxies that now fill the Universe.
The VLT Survey Telescope (VST) at ESO’s Paranal Observatory in Chile has imaged a fascinating collection of interacting galaxies in the Hercules galaxy cluster.
Very Large Telescope -- The Very Large Telescope (VLT) consist of four optical telescopes that have 8.4 meter aperture. The VLT is a project of the European Southern Observatory organization. It is located at the Paranal Observatory on Cerro Paranal, a 2,635-m high mountain in the Atacama desert in northern Chile. The VLT consists of a cluster four of large telescopes, and an interferometer (VLTI) which will be used to resolve fine features. The telescopes have been named after the...
Adaptive Optics -- Adaptive optics is a technology to improve the performance of Earth-based telescopes, reversing the effect of atmospheric distortions. When light from a star or another astronomical object enters the Earth's atmosphere, the different temperature layers and different wind speeds distort and move the image in various ways (see seeing for a proper discussion). The net result is that an 8 meters or 10 meters telescope (like the VLT or Keck), while theoretically capable...
Overwhelmingly Large Telescope -- The European Southern Observatory has undertaken a concept study for the next generation of ground-based Extremely Large Telescopes (ELTs). Dubbed OWL, ESO's concept is conceived as a 100 m. diameter optical and near-infrared, adaptive telescope. With milliarc second resolution and limiting magnitude V~38, OWL will be capable of imaging solar system objects at resolutions comparable to that offered by space probes, over much longer time scales. It...
European Southern Observatory -- ESO, the European Southern Observatory, was created in 1962 to: "establish and operate an astronomical observatory in the southern hemisphere, equipped with powerful instruments, with the aim of furthering and organising collaboration in astronomy". ESO is supported by Belgium, Denmark, France, Germany, Italy, the Netherlands, Portugal, Sweden, Switzerland and United Kingdom. Other countries have expressed interest to become a member as well. ESO...
