“Antarctica Alert” –Ghostly Supermassive Black Hole Invader

On Sept. 22, 2017, a ghostly particle ejected from a far distant supermassive black hole zipped down from the sky and through the ice of Antarctica at just below the speed of light, with an energy of some 300 trillion electron volts, nearly 50 times the energy delivered by the Large Hadron Collider at CERN, the biggest particle accelerator on Earth.

Cosmic Enigmas at South Pole –“Long-Sought ‘Dark Matter’ or Unknown Frontier of Astrophysics?”

In 2018 a team of physicists linked to the massive IceCube Observatory detector buried under the South Pole, and to a command center at Penn State University, advanced satellites, and several land-based observatories, pinpointed the first known cosmic source of a neutrino, a ghost-like particle that passes through virtually all matter on Earth. It’s estimated that each second there are about 100 billion neutrinos passing through your body. (more…)

“Black Hole Relics?” –Mystery of Enormous Bubbles Towering Over the Milky Way

In 2010, astronomers working with the Fermi Gamma-Ray Space Telescope unveiled a previously unseen structure centered in the Milky Way that spans 50,000 light-years that may be the remnant of an eruption from the supermassive black hole at the center of our galaxy. The structure spans more than half of the visible sky, a region roughly as large as the Milky Way itself, and it may be millions of years old, its origin an unsolved mystery.
