And one of these is the VERA radio astronomy survey, conducted by the Japanese VERA collaboration. It's actually much farther away, which means that the explosion was brighter and more energetic, and requires a new explanation, since previous analyses were performed under the assumption it was relatively low energy.īut we're getting better at calculating those distances, with surveys using the best available technology and techniques working hard to refine our three-dimensional maps of the Milky Way, a field known as astrometry. This means that it's neither as large nor as bright as we thought.Īnother is the object CK Vulpeculae, a star that exploded 350 years ago. A good recent example of this is the red giant star Betelgeuse, which turned out to be closer to Earth than previous measurements suggested. It's relatively easy to map the two-dimensional coordinates of stars and other cosmic objects, but the distances to those objects is a lot harder to figure out.Īnd distances are important - they help us determine the intrinsic brightness of objects. The major perturbation of the orbits of the planets could well throw the Earth or another planet out of the solar system, which would be just as bad, possibly worse, than being eaten by a black hole."īut there is very little cause to be worried, he said, as "the chances of a black hole coming through our solar system are tiny.It's a problem that has long devilled our understanding of space phenomena. He continued: "However, the results of the interaction would be catastrophic well before the Earth is destroyed. "For the Earth to be destroyed, it would have to have a very close encounter with a large black hole," Steven Tingay, an astrophysicist and executive director of the Curtin Institute of Radio Astronomy at Curtin University, told Newsweek. Some have even theorized that there could be a black hole lurking on the edge of our solar system, silently influencing the orbits of the outer planets with its gravity. We are a bit lucky to have such a heavy, easily studied black hole binary nearby."īlack holes can drift across the galaxy rather than orbiting the galactic center, as our sun does. He continued: "At 1,500 light-years, this is not quite as close as statistics would suggest for the nearest source, but is not that far off. "There may well be a handful of closer black holes, a few in binaries and a few single, which are almost impossible to discover except via deflection of background light, which may have recently been done," Roger Romani, a professor of physics at Stanford University, told Newsweek. Since black holes don't even let light escape, they are more or less invisible and difficult to detect. Woman gave "Russian astronaut" $30,000 so he could pay Earth landing fees. Scientist Works Out There Is Over 15,000 Pounds of Human Trash on Mars.Could There Be a Black Hole Lurking on the Edge of the Solar System?.In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules. If You Fell Into a Black Hole, You'd Be Frozen in Space and Time Forever Would you feel pain in a black hole The fate of anyone falling into a black hole would be a painful spaghettification, an idea popularized by Stephen Hawking in his book A Brief History of Time.Supernova that just hit Earth was unlike anything astronomers had ever seen.If the initial mass of the star is high enough, a black hole is created," Peissker said. "If the hydrogen is used up, there is no outwards-directed radiation that balances the inward-directed pressure. This is called the hydrostatic equilibrium. Nevertheless, this merging of elements causes outwards-directed radiation which equalizes the inwardly directed pressure. To fully understand this process, one has to consider relativistic events. He continued: "Hydrogen, the most common building block in the universe, inside of the star merges with each other and creates helium. These jets can stretch for millions of light-years. Black holes don’t emit light, but their gravity can gather disks of hot gas around them and eject some of that material into space. "To get a better picture of this process, one has to understand that the pressure, due to its mass, of a non-collapsed star causes merging events," Florian Peissker, an astrophysicist at the University of Cologne in Germany, told Newsweek. Evidence that this supermassive black hole may have a companion comes from observations by radio telescopes on Earth. The Earth's closest black hole neighbor, 1,550 light-years away, has been discovered. A stock image shows an artist's illustration of a black hole.
