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

“Intergalactic Pinball” — Millions of Strange, Jupiter-Sized Objects Lurking in the Milky Way

Milky Way's Supermassive Black Hole

 

There could be millions of strange Jupiter-sized, almost-planets in the Milky Way created by the monster black hole that lurks at its center, says UCLA’s Andrea Ghez, an expert on our galaxy’s central black hole, Sagittarius A*. “Still more could be interlopers from our neighboring galaxies, punted into space by their central black holes in an epic game of intergalactic pinball.”

Milky Way Alert –“Sagittarius A* Our Galaxy’s Black Hole Suddenly Flashing 75-Times Brighter”

Milky Way Galaxy

 

A UCLA astronomer at the Keck Telescope, astrophysicist Tuan Do, Deputy Director of the Galactic Center Group, reports that in the space of two hours, the brightness of black hole the heart of our galaxy usually a passive flickering object about twenty-five thousand light years from Earth, has increased 75-fold – the brightest it has been since scientists first started studying it more than 20 years ago.

“Chaos Central” –Huge Nebulous Ring Observed Around Milky Way’s Black Hole

 

Accretion Disk of Milky Way Supermassive Black Hole

 

Through decades of study, astronomers have developed a clearer picture of the chaotic and crowded neighborhood surrounding the supermassive black hole, Sagittarius A*, at the center of the Milky Way — a region dense with roving stars, interstellar dust clouds, and a large reservoir of both phenomenally hot and comparatively colder gases. These gases are expected to orbit the black hole in a vast accretion disk that’s siphoning material extending a few tenths of a light-year from the black hole’s event horizon. (more…)

“We’ve been studying black holes so long that sometimes it’s easy to forget that none of us has actually seen one,” said France Córdova, the director of the National Science Foundation, which funded the effort to capture humanity’s first image of a black hole. The Event Horizon Telescope is actually 10 telescopes, linked across four continents in the United States, Mexico, Chile, Spain, and Antarctica, and designed to scan the cosmos in radio waves. For a few days in April 2017, the observatories studied the skies in tandem, creating a gargantuan telescope nearly the size of the planet.
