Quasar Or Quasi-Stellar Object

A quasar (also known as a QSO or quasi-stellar object) is an extremely luminous active galactic nucleus. Most large galaxies contain a supermassive central black hole with mass ranging from millions to billions of Solar masses. In quasars and other types of AGN, the black hole is surrounded by a gaseous accretion disk. As gas in the accretion...

Bellatrix - The Blue Super Giant!

Bellatrix - The Blue Super Giant! Bellatrix, also designated Gamma Orionis is the third-brightest star in the constellation of Orion, 5° west of the red giant Alpha Orionis (Betelgeuse). Just between the first and second magnitude and slightly variable, it is about the 25th-brightest star in the night sky. Sun's Comparison With Bellatrix Bellatrix...

The Sun Reverses its Magnetic Poles

This visualization shows the position of the sun's magnetic fields from January 1997 to December 2013. The field lines swarm with activity: The magenta lines show where the sun's overall field is negative and the green lines show where it is positive. A region with more electrons is negative, the region with less is labeled positive. Additional...

The Paradox Of Dark Matter

It has long been observed for years that many regional stars of our galaxy have velocities orbit around its center, much larger than the escape velocity and nevertheless remain in orbit. This led to the conclusion that there is somewhere invisible matter, at least ten times from the known, which causes an increase of gravity needed to keep the...

The Paradox Of The Great Acceleration Of Gravity On The Surface Of A Neutron Star

In a neutron star with mass Mns = 1,4MS (MS = Solar mass) and radius Rns = 10 Km, the acceleration of gravity at the surface, of which comply with existing theory, is: This means a body that performs free fall on the surface will change its speed during       ΔU = 1,85859 ∙ 10 ^ 12 m / s at every second. This speed but is...
