The first image of a black hole , previously thought nigh impossible to capture, was named the top scientific breakthrough of 2019 by the journal Science.
Black holes have gravitational pulls so powerful that, past thresholds known as their event horizons, nothing can escape, not even light. Supermassive black holes millions to billions of times the mass of our sun are thought to lurk in the hearts of virtually every large galaxy, influencing the fate of every star caught in their gravitational thrall.

Black hole CATACLYSM: Earth falling into black hole will release unimaginable energy | Science |
Black holes are the terrifying result of colossal stars burning out of their fuel and collapsing under their own crushing weight. The collapse forces the spent star’s remaining mass to squeeze and compress into a single point known as the singularity.
The black hole singularity is the source of a black hole’s powerful gravity – a one-dimensional point in an infinitely small space.
The power of gravity in a black hole is such that time and space become warped and nothing, not even light, can escape once absorbed past the so-called event horizon.
Ask Ethan: Can Black Holes Ever Spit Anything Back Out?
This artist's impression shows how J043947.08+163415.7, a very distant quasar powered by a ... [+] supermassive black hole, may look close up. This object is by far the brightest quasar yet discovered in the early Universe, but only in terms of apparent, not intrinsic, brightness.
Black holes just might be the most extreme objects that exist in the entire Universe. While every quantum of matter or energy is affected by the gravitational force, there are other forces capable of overcoming gravity everywhere you go, except inside a black hole. The most important feature of a black hole is the existence of an event horizon; no other class of object has them.
Black hole bombshell: Astronomers now know how 'monster' black holes are born | Science
Supermassive black holes came into being during a little-understood era dubbed the Cosmic Dawn. Until now, it was unknown how these black holes grew to such enormous sizes – up to one hundred thousand times larger than our Sun.
But due to the incredible distances between our world and the black holes astronomers can look into the past for clues.
We are now able to demonstrate ... primordial galaxies do have enough food in their environments to sustain both the growth of supermassive black holes and vigorous star formation

"End of Space & Time" --A Black Hole Observed at the Dawn of the Cosmos | The Daily
"The gates of hell, the end of space and time," was how black holes were described at the press conference in Brussels where the first ever photograph of one in galaxy M87 was revealed in April 2019. A new image has just be released by the European Southern Observatory (ESO) of a black hole and its halo at the dawn of the cosmos at redshift 6.2, meaning they are being seen as they were 12.8 billion years ago.

The gas halos newly observed with the MUSE instrument on ESO’s Very Large Telescope shown above is superimposed to an older image of a galaxy merger obtained with the ALMA array. The large-scale halo of hydrogen gas is shown in blue, while the ALMA data is shown in orange. The halo is bound to the galaxy, which contains a quasar at its center.
Concert examines black holes, figurative and literal | Manitou Messenger
Science nerds everywhere were in awe this summer when an international group of astronomers first captured a black hole on photo. The Event Horizon Telescope, an international collaboration to photograph black holes, photographed the Powhei Black Hole, an unprecedented feat that left people all across the world amazed. Spiritus Novus, a St. Olaf student-run choir that performs newly composed choral music, celebrated this remarkable image in their Nov. 22 concert, “The Music of the Void.
UC Berkeley student disproves discovery of gigantic black hole
UC Berkeley astrophysics graduate student Kareem El-Badry disproved a discovery by Chinese researchers of a gigantic black hole Dec. 9.
El-Badry said he was skeptical when he first read the original study three weeks ago, which claimed the discovery of a black hole 70 times the size of the sun. The claim would have been extraordinary if it were true, according to El-Badry, as the type of black hole discovered is usually expected to be less than half that size — which would have potentially shed doubt on the established theoretical model of how a star evolves.

Massive, ubiquitous, and in some cases as big as our Solar System, black holes hide in plain sight. The effect of their gravity on objects around them and, lately, the gravitational waves emitted when they collide reveal their presence. But no one had ever seen one directly—until April. That's when an international team of radio astronomers released a startling close-up image of a black hole's "shadow," showing a dark heart surrounded by a ring of light created by photons zipping around it.
