NASA’s Osiris Rex asteroid probe has found that the asteroid Bennu has thrown debris from its surface into space. These “particle ejections” occur frequently, and NASA scientists have discovered more than 300 times. In the future, scientists hope to find an explanation for why this happens and what processes on the surface or below drive it. < / P > < p > NASA’s asteroid probe Osiris Rex has been flying around a huge space rock called Bennu for nearly two years. In the meantime, it made many interesting observations of the asteroid. First of all, its surface is full of rough and dense gravel, which is an unexpected discovery for scientists. < / P > < p > now, NASA has revealed that the asteroid’s surface is actually peeling off. The rock regularly releases material from its surface, which scientists have been observing and tracking for some time. These particles appear as explosions, and scientists have been eager to understand the reasons behind these seemingly random jets. < / P > < p > Bennu’s particles were found almost entirely by accident. In some routine observations, the researchers noticed that there was something in the space around Bennu that shouldn’t exist. I looked at the star patterns in these images and thought, “I don’t remember that cluster anymore,” Carl hergenrother, lead author of the new research paper, said in a statement. “I only noticed it because there were 200 spots of light and there should be about 10 stars there. Besides, it seems to be just a dense part of the sky. ” After careful observation, scientists soon realized that the mysterious “stars” they saw were actually a small part of the asteroid itself. So the question is, why do these particles float in space, and how do they escape from Bennu’s surface? < / P > < p > “we believe that Bennu’s boulder covered surface is an important discovery of asteroids, but these particle events absolutely surprise us,” said Dante Lauretta, chief researcher at Osiris Rex. &We spent a year investigating Bennu’s active surface, which provides us with an extraordinary opportunity to expand our understanding of the behavior of active asteroids. &According to NASA, the Osiris Rex team has observed as many as 300 “particle ejections” from asteroid surfaces. The particles are so tiny that they’re hard to track, but scientists have been trying to figure out what’s going on, and they’re controlling their excitement over new discoveries. < / P > < p > “a particle came down, hit a boulder, and then went back into orbit,” hergenrother said. “If Bennu has this activity, it’s very likely that all asteroids have this activity, which is really exciting.” Epic Games accused Google of monopolizing the latter, which may have a better chance than apple
