Researchers have found over 1,700 asteroid trails in archived Hubble data from the last 20 years. While many of the asteroids are previously known, more than 1,000 are not. What good are another 1,000 asteroids? Like all asteroids, they could hold va

The astronomers released the results of their project in a new paper titled. The lead author is Sandor Kruk from the Max Planck Institute for Extraterrestrial Physics.Asteroid 2001 SE101 passing in front of the Crab Nebula, 5 December 2005.

The streaks go to the heart of the problem: computers struggle to detect them. That's where the Zooniverse platform and citizen scientists come in. The volunteers delivered. 11,482 citizen scientists took part in classifying the images. The Hubble Asteroid Hunter page at Zooniverse had over 2 million clicks, and the volunteers provided 1488 positive classifications in about 1 percent of the images.

Above: This mosaic consists of 16 different data sets from the NASA/ESA Hubble Space Telescope studied as part of the Asteroid Hunter citizen science project. Each of these datasets was color-assigned based on the time sequence of exposures, whereby the blue tones represent the first exposure that the asteroid was captured in and the red tones represent the last.

"The asteroids are remnants from the formation of our Solar System, which means that we can learn more about the conditions when our planets were born," Kruk explained. Astronomers want a complete understanding of the Solar System's asteroid population because it helps clarify the Solar System's history.
