Illustration depicting a tidal disruption event surrounding a supermassive black hole. NASA, ESA, STScI, Ralf Crawford (STScI) Black holes are the ravenous giants of the universe: extremely dense entities capable of consuming any material that ventures too close and then obliterating it. Recent observations from astronomers using the Hubble Space Telescope have captured a black hole actively consuming a star, tearing it apart and producing a significant burst of radiation. This radiation burst, known as a tidal disruption event (TDE), enabled researchers to locate the black hole. The TDE identified as AT2024tvd was remarkable for a particularly uncommon reason: while most supermassive black holes are usually found at the very center of a galaxy, this one is a nomadic rogue. "The typical location for massive black holes within a galaxy is at the center, similar to our Sag A* at the heart of the Milky Way,” said lead researcher Yuhan Yao from UC Berkeley. "That's where scientists usually look for tidal disruption events. However, this one is not at the center; it’s approximately 2,600 light years away. It is the first optically discovered off-nuclear TDE." A six-panel illustration showcases a tidal disruption event around a supermassive black hole. NASA, ESA, STScI, Ralf Crawford (STScI) In addition to Hubble, researchers utilized other instruments like NASA’s Chandra X-Ray Observatory and the NRAO Very Large Array telescope to study the TDE — as depicted above. The black hole starts as a dark and elusive object, but when a star approaches too closely, it is gravitationally captured and elongated, or more technically, “spaghettified” into an extreme form. This process results in a disk-shaped cloud of material encircling the black hole, and this material rapidly spirals into the black hole, generating a flash of radiation across X-ray to radio wavelengths that can be detected from Earth, revealing that the black hole is not centrally located in the galaxy as anticipated. In fact, this galaxy contains not just one supermassive black hole, but two: one at the galactic center and the other as a wandering entity. It is believed that this situation arises when two smaller galaxies collide and merge to create a larger galaxy. “Massive black holes typically reside at the centers of galaxies, but we know that galaxies undergo mergers — that is how they grow. When two galaxies combine to become one, multiple black holes emerge,” explained co-author Ryan Chornock, also from UC Berkeley. “What happens next? We anticipate that they will eventually coalesce, but theorists have predicted a population of black holes that roam within galaxies.” The researchers suggest that the two supermassive black holes in this galaxy could potentially merge in the future, a monumental event that would generate gravitational waves capable of being detected from Earth. This research is set to be published in The Astrophysical Journal Letters. Georgina has been writing about space for Digital Trends for six years, covering topics related to human space exploration and planetary… Amazing image reveals the magnetic fields of our galaxy’s supermassive black hole The Event Horizon Telescope collaboration, known for capturing the historic first image of a black hole, has produced another stunning black hole image. This one illustrates the magnetic fields swirling around the supermassive black hole located at the center of our galaxy, Sagittarius A*. Black holes are difficult to photograph because they engulf anything that strays too close, including light, due to their immensely strong gravitational pull. However, this does not render them invisible. While the black hole itself cannot be seen, the material circling around the edges of the event horizon glows brightly enough to be captured on camera. This new image utilizes a property of light known as polarization to unveil the powerful magnetic fields surrounding the massive black hole. Read more Hubble captures the striking jets of a newborn star A recent image from the Hubble Space Telescope showcases the incredible events occurring as a new star comes into existence. Within a swirling cloud of dust and gas, a newly formed star is emitting powerful jets, ejecting material and cutting through the dust of the surrounding nebula to create this breathtaking scene. The image depicts a system referred to as FS Tau, situated 450 light-years away within a region known as Taurus-Auriga. This area hosts many stellar nurseries where new stars are forming, making it a popular target for astronomers examining star formation. However, this particular system is distinguished by the dramatic characteristics of its newborn star, which has developed an impressive structure known as a Herbig-Haro object.
