A supernova explosion effect weighing 100 Earth masses radioactive titanium


According to scientists, a single supernova explosion in the surrounding area can be radioactive titanium, the total weight of which can exceed 100 times the mass of our planet.

These new data, to dispose of the radioactive substance during a supernova explosion, it may give an explanation of the mysterious processes occurring inside stars just before they are followed by a catastrophic explosion and the release of elements from which the universe is almost everything, from the stars and planets and ending human .

supernova nuclear blasts produce a paste


When dying stars detonate as supernovae, spread out a shock wave lead the so-called "rebound" - matter and elementary particles are compressed towards the center of the star to achieve the density that come into play in the nuclear force.

In the development of a supernova nuclear particles can create different and often bizarre forms, such as rods, plates or vials and long threads - which gave the name to this phenomenon, associated with the famous Italian pasta. Creating a "paste" because in the dying star DIURNAL two types of forces - the Coulomb revulsion of the same charges and nuclear forces of attraction.

What occur to the very first stars in the universe?


Most distant and bright supernova, known to scientists today, probably happens in the explosions when the universe was much younger - just after the Big Bang.

What both these unusually bright and slowly fading. These properties are consistent with what is known as a supernova with the pair instability, a rare explosion mechanism, which is expected to occur with massive stars, is substantially free of metals.

Discovered the most rapidly rotating superdense star


Scientists have found evidence of what may be the fastest moving pulsar. During the observation using three different telescopes - NASA's X-ray Observatory "Chandra", ESA XMM-Newton, located in space, and a radio telescope Parks in Australia.

X-ray observations, "Chandra" and XMM-Newton were combined with infrared data of the project 2MASS optical data and digital images of the sky.

Supernova create radioactive titanium



The most powerful planetary explosions in the universe can throw into the environment of radioactive titanium much more than previously thought: almost 100 times the mass of Earth, according to a new study.

These new findings promise to shed light on the mysterious inner processes in supernovae, and how are the elements that make up everything in our universe from planets to people.

The most powerful stellar explosions called supernovae in the universe, and during the explosions in stars processes run fusion, resulting in the formation of heavy elements.

Verification a new supernova black hole


In space telescope NASA "Swift" fixed-ray flashes, indicating the discovery and the survival of a new black hole, which was previously unknown. It is located at 20-30 thousand light-years from Earth. Flash X-ray peak of the supernova occurred on September 18. Flash output is 10 thousand volts, but two days of observation exposed that the radiation has increased by 30 times.

The supernova remnant Simeis 147


This structure, also referred to in catalogs as Sh2-240, covers an area of ​​nearly 3 degrees on the sky (the equivalent of 6 full moons). The mentioned field corresponds to an actual diameter of about 150 light-years, since the debris cloud is at an estimated distance of 3000 years-light. The bright star that dominates the right side of the image is El Nath (Beta Tauri), located toward the boundary between the constellations of Bull (Taurus in Latin) and the Charioteer (Auriga in Latin), on a point of land almost exactly sky opposite to the galactic center.

The victim of a supernova explosion


Scientists are trying to way down the star, which died in the explosion of a supernova that transpires in the past year.

The outbreak of the star was found May 31, 2011 in a rather famous Whirlpool Galaxy (M51), which lies at a distance of 23 million light years from our own Milky Way galaxy. Supernova explosions occur when the supply of fuel massive stars, stellar, completing the life cycle comes to an end, and the stars begin to collapse, turning eventually into a neutron star or black hole.

Multi-tasking Supernova: stellar explosion galaxy far-off


Nature hath no fury like a dying star - and astronomers could not be happier...
An international research team, led by Edo Berger of Harvard University, made the most of a dying star's passion to probe a distant galaxy some 9.5 billion light-years distant. The dying star, which lit the galactic scene, is the MOST distant stellar explosion of its kind ever Studied. According To Berger, "It's like someone turned on a flashlight in a dark room and allowed us to see suddenly, for a short time, what this far-off galaxy looks like, what it is composed of."

X-Rays from Young Supernova Remnant Discovered


Astronomers have detected X-rays from the leftovers of a supernova that was first seen from Earth over 50 years ago. This supernova SN 1957D was call because it was the fourth one detected in the year 1957. Whilst detected in the radio and optical for decades, SN 1957D did not appear in previous X-ray images.

A blue swirl River

Realize with the VLT (Very Large Telescope) of ESO, we see the galaxy NGC 1187. This impressive curved is about 60 million light-years away in the constellation Eridanus (The River). NGC 1187 has hosted two supernova detonations during the last thirty years, most recently in 2007
The galaxy NGC 1187 [1] is seen almost face on the new VLT image, which clearly shows the spiral structure. Can be around half dozen prominent spiral arms, each of contains large amounts of gas and dust.

Superbright Secrets: Germ magnetar


Astronomers continue to fight over the mystery superbright supernova. Supernovae can suddenly shine brighter entire galaxy - in fact in this outbreak are killed biggest stars. There are two types of supernovae. First appear, when one of the stars of the binary system begins to pull stuff from a neighbor, and eventually gaining critical mass.
