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 .

The most powerful explosions of stars - the birth of supernova stars. Moreover, in the process, the synthesis of heavy elements and a process called explosive nucleosynthesis. In the extremely complex, and the majority did not understand, the birth of the supernova at the moment, for today's scientists are still many unknown and incomprehensible. However, according to astrophysics, in the monitoring of supernova explosions, in particular the residual effects of the explosions, you can try to understand the processes that lead to them.

In a recent study, the researchers made ​​the study of the remains of the supernova SN1987A, whose explosion was observed in 1987. This supernova was located on the outskirts of the Nebula Tarantula, which is located in the Large Magellan Cloud, a dwarf galaxy located at a distance of 168,000 light years from the solar system.

During their study, the researchers focused on creating, during the supernova explosion of a radioactive isotope such as titanium-44. According to computer simulations, supernovae such class as SN1987A, can throw in their surroundings to 100 Earth masses in the form of titanium-44.

Using a telescope INTEGRAL, which belongs to the European Space Agency, the scientists looked for very specific wavelengths in X-rays, which are emitted and this particular isotope of titanium. Scientists intend to measure radiation levels in order to get the possibility of estimating the quantity of radioactive material in space. As a result, discovered titanium-44, in the space around the site of the explosion of the supernova SN1987A, enough that the remains of the supernova emitted light is not worse than a little sun.

As a result, scientists have yet another "starting point" for modeling processes that precede the most direct of the supernova explosion, as well as additional material for professionals working in the field of study of explosive nucleosynthesis.
