A black hole discovered in Cosmic Dawn is simply too big to easily explain. It is located at the center of a galaxy called J1120+0641 and has a mass of over a billion suns. There are larger black holes all around us today. The problem is the when of the existence of J1120+0641. Less than … Read more
The sun is on the eve of an important event: a reversal of the magnetic field. This phenomenon occurs approximately every eleven years and marks an important stage in the development of the economy solar cycle. The shift in polarity indicates the halfway point maximum solar energythe height of solar activity and the beginning of … Read more

New research indicates that the Sun’s magnetic field originates much closer to the surface than previously thought, a finding that could help predict periods of extreme solar storms like the one struck the earth earlier this month. It appears that the magnetic field originates 20,000 miles below the surface of the sun. Previous calculations placed … Read more

New research shows that the Sun’s magnetic field originates near the surface and not deep within the star. . This upends decades of prevailing scientific thinking, which placed the field more than 130,000 miles below the surface of the sun. It also brings us closer to understanding the nature of the Sun’s magnetic field, which … Read more
Scientists have found the possible origin of the sun‘s magnetic field, and it’s not where they thought it was. The discovery, made using complex computer simulations, suggests that the Sun’s magnetic field arises from instabilities in the plasma in the outer layers of the Sun’s surface, rather than deep within the star, as researchers previously … Read more
