Chandra X-ray Observatory Sees Runaway Pulsar Firing A Record-breaking Jet
2014-02-19 09:27:55

NASA NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles. The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the collapse and subsequent explosion of a massive star. Originally discovered with the European Space Agency satellite...

Australian National University A team led by astronomers at The Australian National University has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago. The discovery has allowed astronomers for the first time to study the chemistry of the first stars, giving scientists a clearer idea of what the Universe was like in its infancy. "This is the first time that we've been able to unambiguously say that we've found the chemical...

Using Simulations To Chart The Forces Of The Early Universe
2014-02-06 10:13:28

Brett Smith for redOrbit.com - Your Universe Online Most scientific calculations need a reference point to be completed, but what if the calculations are for the beginning of the Universe – where points of reference are somewhat ephemeral? In a new study, published in the Monthly Notices of the Royal Astronomical Society, researchers from The University of Texas at Austin tried to do just that – conduct numerical simulations aimed at charting the forces of the Universe in its first...

OAKLAND, Calif., Jan. 30, 2014 /PRNewswire-USNewswire/ -- Chabot Astronomers are tracking the latest supernova about 12 million light years away. Identified as "2014J," a Type 1A supernova, the phenomenon is occurring in Messier-82 (M82), also known as the Cigar Galaxy. Supernovae occur when a star explodes emitting a massive amount of energy in a short span of time; the star literally collapses under its own gravity. 2014J actually exploded about 12 million...

[ 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

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...

[ 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 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...
