To observe the heart of the M87 galaxy,
the collaboration linked eight telescopes around the world to create a virtual Earth-sized telescope, the EHT
. The impressive resolution obtained with the EHT is equivalent to that needed to measure the length of a credit card on the surface of the Moon.
Is M87 still there?

What type of black hole is M87?
M87 is an enormous elliptical galaxy located 55 million light-years from us. Its
central supermassive
black hole is one of the most massive ones known, and, like a cosmic searchlight, a jet of subatomic particles traveling nearly at the speed of light is streaming out of it, as far out as about 6,000 light-years.
Can you see M87 with binoculars?
On dark moonless nights, M87 is visible with 7×50 or 10×50 binoculars
, appearing as a faint hazy patch of light. This galaxy was one of eight discovered by Charles Messier on March 18, 1781.
Do black holes stretch you?
Your body stretches out, not uncomfortably at first, but over time, the stretching will become more severe
. Astronomers call this spaghettification because the intense gravitational field pulls you into a long, thin piece of spaghetti. When you start feeling pain depends on the size of the black hole.
Can you see M87 with the naked eye?
In this cluster you'll find M87 – though
it's nearly impossible to spot with the naked eye
. However, with a telescope or good pair of binoculars, you should get a glimpse at the galaxy where it's located. “There will be three bright points in that area. The two dots close together are M84 and M86,” Ross said.
What is the biggest known black hole?
TON 618
(This quasar is the biggest black hole, estimated at 66 billion solar masses…)
How far are we from black hole?
The black hole is located about
1,500 light-years
away from Earth. Scientists have discovered what may be the smallest known black hole in the Milky Way galaxy and the closest to our solar system – an object so curious that they nicknamed it ‘the Unicorn. ‘
Is ton 618 the biggest black hole?
Currently
the largest known black hole
, powering the quasar TON 618, has a mass of 66 billion solar masses.
Can a wormhole exist?
Einstein's theory of general relativity mathematically predicts the existence of wormholes, but
none have been discovered to date
. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
How far away is the biggest black hole?
M87 lies about
55 million light-years
from Earth. Black hole at the centre of the massive galaxy M87, about 55 million light-years from Earth, as imaged by the Event Horizon Telescope (EHT).
What is a white black hole?
White holes are
theoretical cosmic regions that function in the opposite way to black holes
. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
How fast is M87 spinning?
Messier 87, star of the first image of the black hole , is spinning
between 2.4 to 6.3 times faster than the speed of light
. According to the laws of physics, the speed of light is the universal speed limit.
How far away is Sagittarius A?
25,640 light years
How far away is Messier 87?
53.49 million light years
How old is Messier 59?
M59 is an elliptical galaxy in Virgo and a member of the Virgo cluster. It was discovered by Johann Gottfried Koehler on
April 11, 1779
while observing a comet in the same region of sky.
Where can I find Messier 87?
What would it be like to be spaghettified?
Because of the tidal forces
it would feel as if you are being stretched head to toe, while your sides would feel like they are being pushed inward
. Eventually the tidal forces would become so strong that they would rip you apart. This effect of tidal stretching is sometimes boringly referred to as spaghettification.
When our sun dies it will make a black hole?
No supernova, no black hole
Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and
it will never become a black hole
either. In order to create a supernova, a star needs about 10 times the mass of our sun.
Where is the nearest black hole?
In 2020 a team led by European Southern Observatory (ESO) astronomers reported the closest black hole to Earth, located just
1000 light-years away in the HR 6819 system
.
Can you survive a black hole?
Regardless of the explanation, we do know that
it is highly unlikely that anyone entering a black hole would survive
. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.
Can u see black holes?
Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon. But
the holes can nevertheless be seen
. As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas.
Do black holes move?
Scientists have long thought black holes could move, but
such movement is rare
because their immense size needs an equally substantial force to get them in motion.
Can a star turn into a planet?
Yes, a star can turn into a planet
, but this transformation only happens for a very particular type of star known as a brown dwarf. Some scientists do not consider brown dwarfs to be true stars because they do not have enough mass to ignite the nuclear fusion of ordinary hydrogen.
How many black holes have we found?
So in our region of the Universe, there are some
100 billion
supermassive black holes. The nearest one resides in the center of our Milky Way galaxy, 28 thousand lightyears away.
What is the biggest thing in the universe?
The biggest single entity that scientists have identified in the universe is
a supercluster of galaxies called the Hercules-Corona Borealis Great Wall
. It's so wide that light takes about 10 billion years to move across the entire structure.
