For example, if you were travelling feet first into a black hole you would be stretched out to a point where you would just be a stream of atoms heading towards the centre.
Thomas Holoien, of the Carnegie Observatories and lead author, said: “TESS data let us see exactly when this destructive event, named ASASSN-19bt, started to get brighter, which we’ve never been able to do before.
“Because we identified the tidal disruption quickly with the ground-based All-Sky Automated Survey for Supernovae (ASAS-SN), we were able to trigger multiwavelength follow-up observations in the first few days.

A Scientist's Tiny Black Hole Brings the Cosmos Into the Lab | WIRED
Each of these tiny blobs consists of 8,000 rubidium atoms that Steinhauer has cooled to near absolute zero and then swished around with a laser. Collectively, the atoms weigh about a thousandth of a single bacterium.
At a real black hole , gravity is so strong that once you cross its event horizon, not even light can escape. Steinhauer's replica, technically called a Bose-Einstein condensate , has the same property but for sound waves . Past a boundary in the blob, no sonic vibrations can escape.
A new type of black hole has been discovered, astronomers say - CNN
(CNN) Astronomers studying black holes in our galaxy, the Milky Way, have discovered what they believe to be a new type of black hole. This previously unknown class of black holes could be smaller than others that were previously dubbed the smallest black holes.
Black hole shock: Scientists reveal bizarre sound of two black holes merging | Science | News |
Black holes are one of the most powerful and forceful objects in the universe, and when two collide they send ripples through space time – known as gravitational waves. The mysterious entities can have a mass tens of billions of times that of the sun, so when two collide you would expect one of the most powerful explosions in the cosmos. But this is not the case.
Instead, observations from the Laser Interferometer Gravitational-Wave Observatory (LIGO) lab revealed the merger of two black holes – each of which were about 30 times the mass of the sun – sounds like a “bird’s chirp”.
Many things are taking place:
Ask Ethan: Did We Just Find The Universe's Missing Black Holes?
This simulation shows the radiation emitted from a binary black hole system. In principle, we should ... [+] have neutron star binaries, black hole binaries, and neutron star-black hole systems, covering the entire allowable mass range. In practice, we see a 'gap' in such binaries between about 2 and 5 solar masses. It is a great puzzle for modern astronomy to find this missing population of objects.
Astronomy has taken us so far into the Universe, from beyond Earth to the planets, stars, and even the galaxies far beyond our Milky Way. We've discovered exotic objects along the way, from interstellar visitors to rogue planets to white dwarfs, neutron stars and black holes.
Dream of Visiting a Black Hole? Maybe Don't, Fun NASA Video Suggests | Space
If you've ever thought about what it might be like to visit a black hole , NASA has shared a few videos and postcards that may have you reconsidering.
NASA's Black Hole Safety video explains what a black hole is, how to find one and a safe distance to keep from falling into one — a boundary known as the event horizon , beyond which nothing can return.

NASA shared a series of postcards warning travelers about the dangers of visiting a black hole.
What is a black hole? Your questions answered. - CSMonitor.com
Last month, NASA released two images of objects that reflect no light: black holes. The first was an animated simulation of light bending around a black hole. The second was an image of three supermassive black holes on a collision course. Earlier this year a global consortium of scientific institutions published a now-iconic image of a black hole's "shadow."
But what are black holes? While our scientific understanding of these mysterious objects is rapidly evolving, scientists today understand them as regions of the universe that are separated, in fundamental ways, from everything else.
Going against the flow around a supermassive black hole
Supermassive black holes already existed when the Universe was young—just a billion years after the Big Bang. But how these extreme objects, 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. This new ALMA discovery could provide a clue.
NGC 1068 (also known as Messier 77) is a spiral galaxy approximately 47 million light-years from Earth in the direction of the constellation Cetus. At its center is an active galactic nucleus , a supermassive black hole that is actively feeding itself from a thin, rotating disk of gas and dust, also known as an accretion disk .
