https://safirsoft.com Astronomers discover a strange galaxy without dark matter
New observations show that dark matter is not as ubiquitous as scientists thought.
But unlike nearly all other galaxies - including our own Milky Way - it does not appear to be in the huge clumps of dark matter that are normally attracted to stellar capitals. Scientists chose a single medium-sized galaxy 250,000 light-years away to zoom in, and 27 radio telescope antennas aimed at a very large group in New Mexico.
After collecting 40 hours of data, they mapped the stars and gases, confirming what the earlier snapshots indicated: "The dark matter content we infer in this galaxy is much smaller than anything else. That's what you'd expect. It's what you'd expect," says Fraternali, an astronomer at the Captain Institute for Astronomy at the University of Groningen. In the Netherlands, if the team or its rivals find other such galaxies, it could challenge scientists' view of dark matter, the dominant landscape for at least 20 years. Fraternali and his team published their findings at the Royal Astronomical Society monthly in December.

Discover a <b>strange</b> <b>galaxy</b> <b>without</b> <b>dark</b> <b>matter</b> Based on decades of telescope observations and computer simulations, scientists have believed that dark matter is the hidden skeleton of the universe. Its "joints" are huge clumps of invisible particles that host galaxies large and small. But the Fraternali is not The first to look at this exception.A few years ago, Yale University astronomer Peter van Dokkum and his colleagues discovered galaxies similar to the Hubble Space Telescope that appear to contain no dark matter. Much of the controversy and controversy because it was "difficult to explain and interpret", and larger and neighboring birds often fly in and may carry dark matter with them. In contrast, the Fraternali galaxy is quite isolated and has no troublesome neighbors, so its lack of dark matter cannot be explained That way. “They could be very important,” says Van Dakom. “How do stars and gas gather there without the help of dark matter?”

These strange objects are called “super-spreading galaxies.” They are extreme values: They are small in mass, but they are scattered over m Big savages. Some are as large as the Milky Way, but only have a hundredth of a star - or even less. They are so close to transparency that it is difficult to spy in the night sky. "It's a little darker in the center, so it's harder to detect. Now, with better telescopes and deeper observations, it's getting better known. For the first time, American astronomer Vera Rubin and others ignored 'dark' matter, or its size. The speed of stars' rotation in galaxies around the center has revealed the speed of rotation of stars in galaxies around the center." that the inner stars rotate at different speeds than the outer stars, and based on the rotation of those stars, the scientists calculated how much mass a galaxy should have instead of many galaxies, this mass was several times greater than the total number of stars. Problem solved.
