April Flowers for redOrbit.com — Your Universe Online A team of astrophysicists from the Center for Astrophysics at the University of Notre Dame are exploring a discrepancy between the amount of lithium predicted by the standard models of elemental production during the Big Bang and the amount of lithium observed in the gas of the Small Magellanic Cloud. The Small Magellanic Cloud is a dwarf galaxy with a diameter of about 7,000 light-years.  It contains several hundred...

ESO Celebrates 50th Anniversary With Contests
2012-08-09 05:17:01

[ Watch the Video: Moon Setting over ESO´s Paranal Observatory ] April Flowers for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) is having its 50th anniversary on October 5, 2012, and ESO is hosting two competitions to celebrate the event. ESO builds and operates some of the most advanced telescopes on Earth, including the Very Large Telescope (VLT) at the Paranal Observatory in Chile. These huge machines have made many fascinating discoveries about...

New research using data from ESO’s Very Large Telescope has revealed that the hottest and brightest stars, which are known as O stars, are often found in close pairs. Many of such binaries transfer mass from one star to another, a kind of stellar vampirism depicted in this artist’s impression. Credi

Lee Rannals for redOrbit.com - Your Universe Online The brightest stars in the universe apparently do not like to live alone, according to a new study using ESO's Very Large Telescope (VLT). Nearly three-quarters of the brightest, high mass stars are found to have a close companion star, which is far more than previous thought. Most of these pairs of stars are also experiencing disruptive interactions, like mass transfer from one star to the other. Another third of them are expected...

Dark Galaxies Of The Early Universe Seen For The First Time
2012-07-11 17:25:51

Dark galaxies are small, gas-rich galaxies in the early Universe that are very inefficient at forming stars. They are predicted by theories of galaxy formation and are thought to be the building blocks of today's bright, star-filled galaxies. Astronomers think that they may have fed large galaxies with much of the gas that later formed into the stars that exist today. Because they are essentially devoid of stars, these dark galaxies don't emit much light, making them very hard to detect....

Dark galaxies spotted for the first time

Lee Rannals for redOrbit.com - Your Universe Online Dark galaxies may have been spotted for the very first time using the European Space Observatory's Very Large Telescope (VLT). An international team of astronomers believe they have detected these elusive objects by observing them as they were lit up by glowing quasars. Dark galaxies are very small, gas-rich galaxies in the early universe that are inefficient at forming stars. Scientists believe these galaxies are building blocks of...

Stellar Nursery Shows Off Its Hot Young Stars In Latest Image
2012-06-20 11:08:48

[ Video 1 ] | [ Video 2 ] ESO´s Very Large Telescope (VLT) has taken the most detailed image so far of a spectacular part of the stellar nursery called NGC 6357. The view shows many hot young stars, glowing clouds of gas and weird dust formations sculpted by ultraviolet radiation and stellar winds. Deep in the Milky Way in the constellation of Scorpius (The Scorpion) lies NGC 6357 [1], a region of space where new stars are being born in of chaotic clouds of gas and dust [2]. The...

Lee Rannals for redOrbit.com [ Watch the video ] The European Extremely Large Telescope (ELT) has been given the go-ahead by the organization overseeing the project to move on with it. The $1.3 billion telescope will look for planets outside the solar system and those orbiting other stars in "habitable zones." The telescope will use a 127-feet mirror, helping it gather more than 12 times the light that the largest optical telescopes being used today gather. "Its unique...

Fourth Summit Of The Pacific Alliance Takes Place At ESO's Paranal Observatory
2012-06-08 03:13:38

Four Presidents at Paranal for signature of Pacific Alliance Treaty 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. The presidents gathered at Paranal for the fourth Summit of the Pacific Alliance, at which the Alliance´s Framework Agreement was ratified. On Wednesday 6 June, Presidents Sebastián...

Astrophysicists Use Three-Telescope Interferometry To Observe How Black Holes Are Fueled
2012-05-18 03:45:33

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, a method that has yielded an unprecedented amount of data for such observations. The resolution at which they were able to observe this highly luminescent active galactic nucleus (AGN) has given them direct confirmation of how mass accretes onto black holes in centers of...

ESO Takes A Deeper Look At Centaurus A Galaxy
2012-05-16 14:17:14

[ Video 1 ] | [ Video 2 ] 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. The image was produced by the Wide Field Imager of the MPG/ESO 2.2-meter telescope at ESO´s La Silla Observatory in Chile. Centaurus A, also known as NGC 5128 [1], is a peculiar massive elliptical galaxy with a...

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...
