“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.

Far Side of the Milky Way –“Star Eight Times Size of Sun Orbiting a Colossal Black Hole”

Black Hole

 

A new gargantua, a black hole known as LB-1, has been discovered lurking at the far side of the Milky Way with a mass that is around 70 times larger than our sun with an orbiting blue monster, a star eight times the size of the sun.

Supermassive Black Hole Cloud –“Unveils Their Rapid Growth in the Early Universe”

Supermassive Black Hole

 

One of the unsolved mysteries of the early universe is why supermassive black holes already existed only a billion years after the Big Bang. How these extreme primordial objects, monsters whose masses are up to billions of times the mass of the Sun, had time to grow in such a relatively short timespan, is an outstanding question among astronomers.

“The Gargantua Hypothesis” –Habitable Planets May Be Orbiting Black Holes

Supermassive Black Hole

 

Two prominent astronomers, Harvard’s Avi Loeb and NASA’s Jeremy Schnittman, have proposed that inhabited planets might exist around the black holes harbored at the center of most galaxies similar to the fictional waterworld planet Miller, the first planet in the system orbiting the supermassive black hole Gargantua in the movie Interstellar. It’s even possible that life may form on some of these planets, given that extremeophiles on Earth have adapted to boiling heat, freezing cold, and acidic, highly salty and even radioactive environments.

“At Emergence of Human Ancestors” –Titanic Beam of Energy Burst from Milky Way’s Black Hole

Milky Way Galaxy

 

“We always thought about our Galaxy as an inactive galaxy, with a not so bright center,” said  Magda Guglielmo from the University of Sydney, about new Hubble Space Telescope data showing that a titanic, expanding beam of energy sprang from close to the SgrA*, the supermassive black hole in the center of the Milky Way, 3.5 million years ago, shooting a cone-shaped burst of radiation through both poles of the Galaxy and beyond into deep space.
