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 .

Nuclear NASA telescopes can see gravitational waves

This advanced technology is developed in the field of measurement, at the atomic level, the degree of change in ambient gravity , as well as for the detection of gravitational waves - ripples sort of space-time, which is caused by various events, including the Big Bang. According to the general theory of relativity, Albert Einstein created; gravitational waves are provided when massive cosmic bodies, during its motion, break the fabric of space and time. 

Irregular galaxies tend to become disks

​​Through the use of Hubble and Keck telescopes, astronomers have come to a rather startling conclusion about the nature, which is the process of change in the "blue" galaxies. Specifically, it relates to a process of change that takes place in these galaxies has for now as eight billion years - in other words, for the period, which is more than half the age of the universe.

Until now, it was assumed that the disk-shaped galaxy with a classic for these galaxies form, appeared in the universe, in its present form, about 8 billion years ago, and only slightly changed in all that time.
