“Extreme!” –Iconic M87 Black Hole Jet Blasts at Close to Speed of Light

M87 Jet

 

“One of the unbreakable laws of physics is that nothing can move faster than the speed of light,” said Brad Snios with the Harvard-Smithsonian Center for Astrophysics about results of new research of the iconic M87 black hole jet in radio, optical, and X-ray light. “We haven’t broken physics, but we have found an example of an amazing phenomenon called superluminal motion.”

“Gargantua” –The Black Hole That Could Swallow Our Solar System (2019 Most Popular)

M87 Black Hole

 

This past April 2019, with an event that was as epic as the Apollo 11 landing on the Moon, the world viewed its first image of what had once been purely theoretical, a black hole at the heart of galaxy M87, frozen in time it was 55 million years ago, the size of our solar system, and bigger, with the mass of six and a half billion suns that was captured by a lens the size of planet Earth and 4,000 times more powerful than the Hubble Space Telescope. Over those eons its light took to reach us, said astrophysicist Janna Levin at Columbia University, “we emerged on Earth along with our myths, differentiated cultures, ideologies, languages and varied beliefs,” (more…)

“Antarctica Alert” –Ghostly Invader from a Supermassive Black Hole Detected

 

Black Hole Gamma Ray Flare

 

“It’s like a crime scene investigation. The case involves an explosion, a suspect, and various pieces of circumstantial evidence,” said Matthias Kadler, astrophysicist at the University of Würzburg in Germany about the event that occurred on Sept. 22, 2017, when a ghostly particle ejected from a distant supermassive black hole sneaked 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.

“Unknown Dark Object” –Burst an Enormous Hole in the Milky Way (2019 Most Popular)

ESA Black Hole Image

 

An enormous “something” more massive than a star, appears to have torn a hole in part of the Milky Way’s halo. The “dark substructure” was found in data from Gaia spacecraft observations—a mission producing the most detailed 3D map of our galaxy—with Harvard’s Ana Bonaca noticing a perturbation in a tidal stream. Bonaca is a leading authority on how the tidal field of the Milky Way galaxy disrupts globular clusters, and what the resulting debris can tell us about the underlying distribution of dark matter.

“Outburst” –Gargantuan Black Hole Punches Two Holes in the Cosmos

 

Gargantua Black Hole

 

The outburst was equal to 1,038 nuclear bombs. “This is an extreme case…” said Michael Calzadilla, at the MIT Kavli Institute for Astrophysics and Space Research (MKI) of a massive black hole explosion in galaxy cluster SPT-0528 so powerful that it punched two holes in the cosmos. Even though the outburst happened billions of years ago, before our solar system had even formed, it took around 6.7 billion years for light from the galaxy cluster to travel all the way to Chandra, NASA’s X-ray emissions observatory that orbits Earth.
