Largest-ever Magnetic Field Found Around Massive Star
2012-09-12 06:10:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have measured the largest-ever magnetic field around a massive star and reported their findings in the journal Monthly Notices of the Royal Astronomical Society. The team used the Hobby-Eberly Telescope (HET) at The University of Texas McDonald Observatory and the Canada-France Hawaii Telescope (CFHT) on Hawaii's Mauna Kea to determine that the star's magnetic field is 20,000 times stronger than the Sun's. The magnetic...

Supernova Lights Up The Galactic Scene
2012-08-31 12:06:23

April Flowers for redOrbit.com - Your Universe Online A recent study, led by Edo Berger of Harvard University, made the most of a dying star's fury to probe a distant galaxy some 9.5 billion light years away. The most distant stellar explosion of its kind ever studied, that dying star lit up the galactic scene. “It´s like someone turned on a flashlight in a dark room and suddenly allowed us to see, for a short time, what this far-off galaxy looks like, what it is composed...

The 'FLOYDS' Spectrographs Acquire Target Robotically At Las Cumbres Observatory
2012-08-29 09:25:08

Two identical FLOYDS spectrographs, installed in recent weeks at telescopes 6,000 miles apart, robotically acquired a supernovae target this week. Due to the level of precision required and the difficulty involved, few if any, other ground-based spectrographs have ever achieved this milestone. “This is unprecedented,” staff astronomer David Sand explained. “In a matter of just a few weeks, Las Cumbres Observatory was able to install the spectrographs, achieve first light,...

Astronomers Observe Type 1a Supernova Progenitor System
2012-08-24 05:07:44

Video: Binary Star System that Produces Recurrent Novae Lee Rannals for redOrbit.com - Your Universe Online For the first time, astronomers have observed a Type 1a supernova progenitor system, according to a report in the journal Science. Previous evidence pointed to the merger of two white dwarf stars as the originators of other Type 1a supernovae. However, this new study led by Ben Dilday, a postdoctoral researcher in physics at UC Santa Barbara and at Las Cumbres Observatory...

Neutrinos Can Alter Exploding Star Physics
2012-08-22 10:27:27

April Flowers for redOrbit.com - Your Universe Online Within the heart of exploding stars, sparse halos of neutrinos exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events. Neutrinos are one of the fundamental particles that make up the Universe. Although neutrinos are similar to the electron, they have one important difference; they carry no electrical charge. Being electrically neutral, they are not...

SuperCloset reviews of indoor grow box trends leads to the grow box industry leader, SuperCloset, Inc., manufacturing the “SuperNova”, the largest rendering of their number one selling grow cabinets. This all in one grow cabinet is 46” wide, 24” deep, and 78” tall. It features a professionally air-cooled, closed loop, 600 watt lighting system. Exclusive to SuperCloset grow cabinets, the closed loop air cool system is comprised of ducting and fans that are...

3D Structure of Supernovae
2012-08-04 06:41:14

Lee Rannals for redOrbit.com - Your Universe Online Japanese researchers using the Faint Object Camera and Spectrograph (FOCAS) on the Subaru Telescope have revealed a clumpy 3D structure of supernovae. The finding supports the clumpy 3D scenario of supernovae explosions, rather than the widely accepted bipolar explosion scenario. The latest research advances the scientific understanding of how supernovae explode, which is a mystery to astronomers. Stars that have reached a mass...

Searching For Supernova Progenitors
2012-08-04 06:23:15

Lee Rannals for redOrbit.com - Your Universe Online A progenitor of a type 1a supernova may have been found, according to findings published in the journal Monthly Notices of the Royal Astronomical Society. Astronomers believe that type 1a supernovae are thermonuclear explosions of a white dwarf star that is part of a binary system, which is two stars that are physically close and orbit a common center of mass. The white dwarf has mass gradually given to it by its companion star, and...

Supernova Shock Wave And Its Role In Solar System Formation
2012-08-03 09:04:16

April Flowers for redOrbit.com - Your Universe Online It has long been thought that our Solar System was formed by the shockwave from a supernova explosion. According to this theory, the shockwave also injected material from the exploding star into a cloud of gas and dust. The newly polluted cloud formed the Sun and its surrounding planets. A new study by Alan Boss and Sandra Keiser of the Carnegie Institution for Science, published in The Astrophysical Journal Letters, provides the...

VLT Finds Deceptively Tranquil Blue Galaxy

Video: Panning Across Spiral Galaxy NGC 1187 | Video: Zooming In On Spiral Galaxy NGC 1187 April Flowers for redOrbit.com - Your Universe Online About 60 million light-years away, there is a beautiful, tranquil looking blue spiral galaxy named NGC 1187. This galaxy is in the constellation of Eridanus, or The River. Researchers at the European Southern Observatory (ESO) have been watching and recording data from NGC 1187 for about a year using the Very Large Telescope (VLT) at the La...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first...

Stellar Evolution -- Stellar evolution is the process of formation, life, and death of stars. It is one of the major topics of cosmogony. Star Birth and Life A star starts out as an enormous cloud of gas and dust many light-years across. Star formation begins when the cloud begins to condense under its own gravity. The processes that initiate this contraction are not fully understood. The cloud fragments fuse into stellar mass clouds known as protostars. Protostars do not emit...

Nova -- A nova is an enormous nuclear explosion caused by the accretion of hydrogen onto the surface of a white dwarf star. When a white dwarf has a close companion star, the companion will often begin to have its outer atmosphere drawn away from it by the white dwarf's gravity as the companion star ages and expands into a red giant. The gases so captured consist primarily of hydrogen and helium, the two principle constituents of matter in the universe. The gases are compacted on the...

Magnetar -- A magnetar is a neutron star with a strong magnetic field. The theory around these objects was formulated by Robert Duncan and Christopher Thompson. When in a supernova a star collapses to a neutron star, its magnetic field increases dramatically in strength. Duncan and Thompson calculated that the magnetic field of a neutron star, normally an already enormous 1012 tesla could under certain circumstances grow even larger, to about 1015 tesla. Such a highly magnetic neutron...
