Monster black hole that ‘should not exist’ discovered in the Milky Way

Monster black hole that ‘should not exist’ discovered in the Milky...

The black hole, LB-1, and its companion star (in blue).  YU Jingchuan/Beijing Planetarium Astronomers think our home galaxy -- the Milky Way -- is practically bursting with black holes, with estimates of up to 100 million of the invisible beasts hiding across the galactic neighborhood. It was generally assumed these black holes could reach a…
Astronomers strategy to movie the great void at the center of the Galaxy galaxy as it demolishes stars and worlds. The video might open a ‘brand-new field’ of science.

In April, an international team of scientists captured the first-ever photo of a black hole. In September, they won a $3 million Breakthrough Prize for that accomplishment. But they're far from finished. Next, the team behind the Event Horizon Telescope (EHT) is planning a cinematic debut. The subject: the supermassive black hole at the center of…
NASA’s brand-new great void simulation is enchanting

NASA’s brand-new great void simulation is enchanting

Warped. NASA's Goddard Space Flight Center/Jeremy Schnittman The first ever image of a black hole, obtained by the Event Horizon Telescope (EHT) collaboration, is one of the most incredible scientific achievements of the past decade. The blurry orange ring snapped from across the universe took an incredible amount of data and smarts to produce. It…

NASA knows a thing or two about black holes. Video screenshot by Amanda Kooser/CNET I learned a lot by watching NASA's Guide to Black Hole Safety, an animated video the Goddard Space Flight Center released on Monday.  I learned a black hole is not a portal to another dimension filled with unicorns and space potatoes.…
New sort of black gap exercise found in dramatic galaxy transformation

New sort of black gap exercise found in dramatic galaxy transformation

At the center of some galaxies, supermassive black holes emit huge amounts of light as they eat up all the matter in their vicinity. NRAO/AUI/NSF;Dana Berry/SkyWorks/ALMA (ESO/NAOJ/NRAO) Astronomers have witnessed a handful of galaxies undergoing sudden, rapid transformations from weak, lethargic states to ferociously bright quasars. The incredibly fast transitions, occurring over a few months,…
The black gap on the heart of our galaxy simply belched two large bubbles of radiation

The black gap on the heart of our galaxy simply belched...

The region at the center of our galaxy is still full of mysteries, but astronomers have just found a clue to its past: Huge, radio-emitting bubbles, extending 700 light-years to either side of the galactic plane. They could be, the researchers believe, the result of a huge eruption from our galaxy's supermassive black hole, Sagittarius…
The supermassive great void at the center of our galaxy unexpectedly illuminated brighter than researchers had actually ever seen, and no one understands why

The supermassive great void at the center of our galaxy unexpectedly...

The supermassive black hole at the center of the Milky Way is normally quiet, but in May it surprised astronomers with an unprecedented explosion of infrared light. The closest supermassive black hole to Earth, called Sagittarius A*, or Sgr A*, suddenly got 75 times brighter than normal along the near-infrared region of the light spectrum…
Our galaxy’s great void gushed an extremely brilliant light, and researchers do not understand why

Our galaxy’s great void gushed an extremely brilliant light, and researchers...

Robin Dienel/Carnegie Institution for Science In news that reads like the beginning of a dire science fiction novel Sagittarius A*, the supermassive black hole at the centre of our galaxy, has emitted a large burst of infrared radiation brighter than anything ever produced by that black hole. The black hole is well-known to scientists, and…
Uncommon black moon Wednesday presents distinctive skygazing likelihood

Uncommon black moon Wednesday presents distinctive skygazing likelihood

A perigree full moon, or supermoon, is seen Sunday, August 10, 2014, in Washington. A supermoon occurs when the moon's orbit is closest (perigee) to Earth at the same time it's full. NASA/Bill Ingalls An unusual type of supermoon is set to take the stage this week. It's called a "black supermoon," and what makes…

An artist's illustration depicts a quasar, or supermassive, ultra-luminous black hole. Credit: NASA/ESA About 13 billion years ago, when our universe was still just a scrappy startup, the cosmos hit a creative streak and churned out supermassive black holes left, right and center. Astronomers can still sneak a peek at these relics of the early…
