Astronomers Have Captured the Most Detailed Photo of a Black Hole EverSee the Magnetic Fields That Power It Here – artnet News

Two years ago, astronomers managed to photograph a black hole for the very first time. The team behind theEvent Horizon Telescopeproject was awarded the Breakthrough Prizeknown as the Oscars of sciencefor their effort, and New Yorks Museum of Modern Art acquired the image in the form of an inkjet print.

Now, the same astronomers have captured the most detailed photograph to date of a black hole, one of the universes most enigmatic features, which was once thought to be unobservable.

Seen in polarized light, the fuzzy ring of light in the original image is now in focus, with crisp lines swirling in toward the center of what appears to be a bottomless pit, sucking in anything and everything within its grasp.

Its like putting on a pair of polarized sunglasses on a bright sunny dayall of a sudden you can see whats going on, astronomer Sheperd Doeleman of the Harvard-Smithsonian Center for Astrophysics told the New York Times.

The Event Horizon Telescope was designed to capture images of a black hole. The image shows the light around the black holes boundary. Image courtesy of the Event Horizon Telescope.

A black hole is a field of matter so dense that not even rays of light can escape its gravitational pull. But as the black hole inexorably draws in gas, dust, and stars, some light is actually propelled outward in jets of energetic particles.

This jet process is totally amazingsomething the size of our solar system can shoot out a jet that pierces through entire galaxies and even galaxy neighborhoods, Event Horizon Telescope team member Sara Issaoun told IGN.

The new image shows the black holes vortex, and the magnetic field lines at its inner edge, illustrating how the magnetic field both feeds the black holes insatiable hunger and powers the intergalactic fireworks show that surrounds it.

The main finding is that we not only see the magnetic fields near the black hole as expected, but they also appear to be strong. Our results indicate that the magnetic fields can push the gas around and resist being stretched. The result is an interesting clue to how black holes feed on gas and grow,Jason Dexter, a professor at the University of Colorado Boulder, told Space.com.

We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy, said Monika Mocibrodzka, coordinator of the EHT Polarimetry Working Group, in a statement.

The findings from the new image are the subject of three papers published last week in the Astrophysical Journal Letters, two by the Event Horizon Telescope Collaboration and one by lead author Ciriaco Goddi of Radboud University in the Netherlands.

This black hole captured by the telescope lies 55 million light-years away, at the heart Messier 87, a supergiant elliptical galaxy in the constellation Virgo.At 6.5 billion times bigger than our sun, it is unimaginably supermassivethe surrounding circular field of electrified gas or plasma captured in the image measures about 30 billion miles across, or four times Plutos orbit.

Capturing the image was a global effort. TheEvent Horizon Telescope collaboration is powered by eight ground-based radio telescopes in Chile, Mexico, Spain, Hawaii, Arizona, and the Antarctic, overseen by an international team of radio astronomers thatsynchronize their observations by atomic clock. Together, the sites essentially create a planet-sized telescope.

The projects name comes from the point of no return around a black hole. Beyond the event horizon, no light or matter can escape.
