“The new MeerKAT observations have been a game changer,” Yusef-Zadeh said. The researchers found the structures by analyzing images produced by the South African Radio Astronomy Observatory’s MeerKAT telescope, which has 64 satellite dishes that are each 65 feet (nearly 20 meters) tall and connected across 5 miles (about 8 kilometers) of a sparsely populated area with minimal interference. “But this work provides evidence that it was recently ejecting quite a lot of energy into space in the form of a jet and conical outflow.” Sagittarius A* “is the closest supermassive black hole to us, but it’s relatively quiet and therefore somewhat difficult to really study,” Hamden added. The findings related to the black hole located about 26,000 light-years from Earth are “really exciting” and “demonstrate how beautiful the universe is,” said Erika Hamden, an assistant professor of astronomy at the University of Arizona who wasn’t involved in the study. … It is satisfying when one finds order in (the) middle of a chaotic field of the nucleus of our galaxy.” “We found that these filaments are not random but appear to be tied to the outflow of our black hole. We had to do a lot of work to establish that we weren’t fooling ourselves,” added Yusef-Zadeh, who’s also a member of the Center for Interdisciplinary Exploration and Research in Astrophysics. “I was actually stunned when I saw these. See images from the first Mars live stream The new study both reinforces and builds upon the earlier findings.įinding the “new population of structures that seem to be pointing in the direction of the black hole” was a surprise, Yusef-Zadeh, a professor of physics and astronomy at Northwestern University’s Weinberg College of Arts and Sciences, said in a news release. Yusef-Zadeh and collaborators also found hundreds more paired and clustered vertical filaments in the same area in 2022, realizing the filaments were likely related to Sagittarius A* activity rather than bursts of supernovae, which they had previously thought. The findings come nearly 40 years after Farhad Yusef-Zadeh, the study’s lead author, and other researchers discovered another population of nearly 1,000 one-dimensional filaments, which are vertical and much larger at up to 150 light-years long each, near the galaxy’s center. The filaments are relatively short in length, each measuring 5 to 10 light-years. These one-dimensional cosmic threads are hundreds of horizontal or radial filaments - slender, elongated bodies of luminous gas that potentially originated a few million years ago when outflow from Sagittarius A*, the Milky Way’s central supermassive black hole, interacted with surrounding materials, according to a study published Friday in The Astrophysical Journal Letters.

Around 98% of Gaia's light was blocked by its invisible partner, the white dwarf, during its eclipse. In our solar system, there is enough white dwarf dust to cover the void between the Sun and Earth completely. Therefore, the chance to witness this bright star being blocked out by its dusty partner is once in a lifetime. “These two stars travel a distance of up to 1,000 years in their orbits around one another.

Washington University researchers saw a distant star that was dim but suddenly became brighter as they unintentionally witnessed the conclusion of a seven-year eclipse, which would be called a "once-in-a-lifetime event.” Gaia 17 Bpp, a star in our universe, began acting abnormally. Scientists have discovered something unusual that we don't see every day.
