[ Watch the Video: Inside-out Formation Of The Milky Way ] Brett Smith for redOrbit.com - Your Universe Online New research from the European Space Agency's (ESA) Gaia-ESO project has confirmed previous theories on the inside-out development of the Milky Way, with the inner regions of the galaxy’s disc being the first to form. According to their report in the astronomical database Astro-ph, the study researchers reached their conclusions using observations taken with the 8-meter...

Our Understanding of the Universe MAXI-mized By The International Space Station
2014-01-16 08:31:10

NASA Look up at the night sky … do you see it? The stars of the cosmos bursting in magnificent explosions of death and rebirth! No? Well, then maybe you are not looking through the “eyes” of the Monitor of All-sky X-ray Image (MAXI) investigation, mounted on the exterior of the International Space Station Kibo module. MAXI, along with other sky watching instruments, such as Swift, collect data that help researchers discover, study and understand the physics behind the powerful...

Supernova Dust Factory

[ Watch the Video: Supernovas May Be Galactic Dust Factories ] Lee Rannals for redOrbit.com - Your Universe Online A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have observed the remains of supernova 1987A located in the Large Magellanic Cloud about 168,000 light-years from Earth. This is the closest observed supernova explosion since Johannes...

Supernova Legacy Survey Astronomers Reveal New Class Of Supernovae
2013-12-19 04:50:57

April Flowers for redOrbit.com - Your Universe Online Two of the brightest and most distant supernovae ever recorded have been discovered by astronomers affiliated with the Supernova Legacy Survey (SNLS). The findings, published in The Astrophysical Journal, reveal that the supernovae are 10 billion light-years away and a hundred times more luminous than a normal supernova. The extreme luminosity of these supernovae cannot be explained by the mechanism that powers most supernovae —...

[ Watch the Video: Supernova Remnant Shows Signs Of Noble Gas ] redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the UK have discovered argon hydride within the Crab Nebula, marking the first time that noble gas molecules have been detected in space, according to research appearing in Friday’s edition of the journal Science. As part of their study, Mike Barlow of the University College London Department of Physics and Astronomy and his colleagues used the...

Tycho Supernova Mach 1000 Shock Wave
2013-11-26 15:49:52

John P. Millis, PhD for redOrbit.com - Your Universe Online Somewhere in the Universe a star or stellar remnant is preparing to explode. Binary white dwarf systems can build up in mass as the compact object accretes mass from its companion. Eventually, the tiny ball of matter will explode in a brilliant event known as a supernova. The blast can glow for weeks or even months before eventually fading. However, the shock wave from the event will travel through the surrounding medium,...

LED grow box systems manufacturer, SuperCloset, has released the LED SuperNova, the largest LED grow box on the market today. The increase in grow space and electricity cost savings provided by the LED lighting system enables the SuperNova to be one of the most sought after hydroponic grow boxes. San Francisco, CA (PRWEB) November 20, 2013 The SuperNova stands at 78” tall is 46” wide and 24” deep. It is a behemoth of a hydroponic grow cabinet. It possesses an oversized grow area...

Astronomers Say Supernova Will Be Visible From Earth Within 50 Years
2013-10-31 16:04:47

[ Watch the Video: Is There A Supernova In Your Future? ] Brett Smith for redOrbit.com - Your Universe Online A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way Galaxy within the next 50 years. While the odds of actually seeing a star explode with the naked eye is very low during that time span, a supernova would be visible to specialized telescopes in the form of...

Violent Youth Seeded The Universe With Iron
2013-10-31 05:07:20

April Flowers for redOrbit.com - Your Universe Online The universe underwent a turbulent and violent youth more than 10 billion years ago, as evidenced by iron spread evenly between galaxies in one of the largest galaxy clusters in the Universe. This violent youth was responsible for seeding the cosmos with iron and other heavy elements that are critical to life itself, according to the new study published in Nature. Scientists from the Kavli Institute for Particle Astrophysics and...

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...
