NASA Reveals That Asteroid Bennu Ejects Particles In Space



Asteroids firing particles are rare. The chances of an asteroid separating particles also being the one NASA has chosen to monitor are even more rare. This means that Bennu is an active asteroid, of which only a dozen were found among almost 800,000 that the scientists had observed. "The discovery of fins is one of the greatest surprises in my scientific career," said Dante Lauretta, chief research officer at Osiri-Rex at the University of Arizona, Tucson, in a NASA press release. an explosion on the surface of Bennu on January 6. Nearly a dozen will come in the next few months. After deciding that the particles would not pose a risk to the spacecraft, the mission team decided to follow them to analyze their potential causes. The team is still discovering exploding particles to this day.

Other discoveries from Bennu capture unprepared scientists. To begin with, the number of stones on Bennu's surface is an unexpected discovery. Based on observations from the Earth, the scientists expected Bennu to have a smooth surface ̵

The spacecraft also finds magnetism on Bennu's surface, supporting earlier the discovery that the rock interacts with liquid water on Bennu's parent body. Bennu's mission brings a lot of new data and new questions. – I think the composition and especially the pen were unexpected and therefore very exciting. said Scott Hubbard of Stanford University in an email to Engadget. Can Bennu's stains resemble the icy, geyser jets found on Enceladus, Saturn's Moon? Or can they be anything else?

Professor Avi Loughb, chair of Harvard University's Astronomy Department, told Engadget that the latest discoveries about the asteroid in Bennu remind him of an Oscar Wilde quotation: I do not know very well for me. "
