You may or may not have heard about blue stragglers; they are blue stars that are hotter and bluer than other stars with the same luminosity. Until now, it seemed that these stars defied most if not all of the standard stellar theories, but scientists now believe they have finally solved this stellar mistery.
The research [...]
Recently, NASA’s Fermi Gamma-ray Space Telescope discovered no more, no less than 12 pulsars, and it also detected gamma ray pulse from 18 others. These findings are forcing scientists to rethink what we know about dying stars, as they totally underestimated the power of these stellar cilinders.
“We know of 1,800 pulsars, but until Fermi we [...]
Actually, it’s not about the brightest star of all, but the brightest star in our galaxy. It seems there’s a new contender for the title of Milky Way brightest star; it’s near its dusty center, and infrared observations performed by NASA have revealed how bright it is by piercing the dust that surrounds it.
The thing [...]
We have another piece of evidence which goes to show that we fail to understand numerous things about our universe. Astronomers have discovered white dwarf stars with pure carbon atmospheres. It is something that probably nobody would have believed.
These stars could have evolved in ways that astronomers did not know. They believe that this kind [...]
