Stunning Solar Images From Big Bear
2013-08-07 08:51:48

April Flowers for redOrbit.com - Your Universe Online New and remarkably detailed photos of the Sun have been obtained by researchers at the New Jersey Institute of Technology's (NJIT) Big Bear Solar Observatory (BBSO) in Big Bear, California, with the New Solar Telescope (NST). Never-before-seen details of solar magnetism revealed in photospheric and chromospheric features are observed in these new photographs. "With our new generation visible imaging spectrometer (VIS), the solar...

Super-Jupiter Planet Observed By Astronomers Using the Subaru Telescope
2013-08-06 05:23:10

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light. Based on the length of the transit, the amount of light that is blocked, and other factors, astronomers can infer a lot of information about the planet. Additionally, researchers will find planets by...

Exploring Hidden Milky Way
2013-08-01 08:48:11

John P. Millis, PhD for redOrbit.com - Your Universe Online Understanding how the Milky Way formed is one of the central scientific questions in astronomy. However, given the scale and complexity of the galaxy, there is a lot to consider. One of the ways researchers have found to tell the story of our galaxy's history is to create a detailed stellar census, analyzing spectra of large numbers of stars. "A star's spectrum is a powerful tool for learning about the star - it tells us key...

Age Of Astronomy Big Data Is Already Here

ICRAR High-performance computing specialists from Perth's International Centre for Radio Astronomy Research (ICRAR) today became the first users of one of Australia's leading supercomputing facilities -- the Pawsey Centre -- ahead of its official opening later this year. The recent launch of the Murchison Widefield Array (MWA) -- a radio telescope based in Western Australia's Mid West -- marked the start of an impressive flow of astronomical data that will be stored in the iVEC-managed...

TW Hydrae’s Snow Line Offers Insight Into Solar System Formation
2013-07-18 18:16:42

Brett Smith for redOrbit.com - Your Universe Online Astronomers at the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have announced the discovery of a distant solar system's "snow line" about 175 light years away, according to a report in Science Express. On Earth, a snow line can be seen at high altitudes, where a mountain's snowcap ends. The concept is similar in space, where a snow line forms at a certain distance from a star. Water, which has one of highest freezing...

Milky Way Black Hole Rips Apart Gas Cloud
2013-07-17 10:54:47

[ Watch the Video: Simulation of Gas Cloud Being Ripped Apart By Black Hole ] Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory's (ESO) Very Large Telescope (VLT) has helped astronomers catch a supermassive black hole ripping apart a gas cloud for the first time. Astronomers writing in the Astrophysical Journal say the gas cloud being ripped apart by the Milky Way's supermassive black hole is now so stretched that its front portion has passed the...

Aircraft Telescope Images Ring Of Dust Surrounding Black Hole
2013-07-10 13:34:10

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using a telescope attached to a modified Boeing 747SP aircraft have captured new images of a ring of gas and dust seven light-years in diameter surrounding the super-massive black hole at the center of the Milky Way. The team used NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) to capture images of our galaxy's circumnuclear ring (CNR), as well as a neighboring cluster of extremely luminous young stars known...

ALMA Scan Reveals Embryonic Star Formation
2013-07-10 05:07:12

[ Watch the Video: Zooming in on the Birth of a Monster Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers used ESO's Atacama Large Millimeter/submillimeter array (ALMA) to gain one of the best views yet of a star in the process of forming. The embryonic monster star sits inside Spitzer Dark Cloud (SDC) 335.579-0.292 right now, which contains over 500 times the mass of the Sun. Astronomers say the cloud will be giving birth to a very brilliant star with up to...

Searching For Water Around Other Stars
2013-07-05 04:46:26

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Astronomers search for planets using several different techniques; the most popular of which is to measure how a star "wobbles." As the surrounding planets orbit the star, their gravitational fields will cause the star to shift back and forth in response. From these wobbles researchers can derive the mass and distance of any planets present in the system. Naturally, astronomers have been hoping for decades now to find an...

Astronomers Catch Distant Galaxy Snacking On Gas
2013-07-04 13:01:16

Lee Rannals for redOrbit.com - Your Universe Online Astronomers were recently able to catch a distant galaxy in the act of snacking on nearby gas while using the European Southern Observatory's (ESO) Very Large Telescope (VLT). The team wrote in the journal Science about how they were able to make the best direct observational evidence so far supporting the theory that galaxies pull in and devour nearby material to grow and form stars. Scientists have always suspected galaxies grow this...

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...

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...

La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...
