Asteroid Detection: New Method Uses James Webb Space Telescope and NVIDIA Accelerated Computing
Asteroids were responsible for extinction events hundreds of millions of years ago on Earth, providing no shortage of doomsday film plots for Hollywood. But researchers focused on asteroid tracking are on a mission to locate them for today’s real-world concerns: planetary defense.
The new and unexpected discovery tool applied in this research is NASA’s James Webb Space Telescope (JWST), which was tapped for views of these asteroids from previous research and enabled by NVIDIA accelerated computing.
Capturing Asteroid Images With Infrared JWST Driven by NVIDIA GPUs
Observatories typically look at the reflected light off asteroids to determine their size, which can be inaccurate. Using a telescope with infrared, like the JWST, can help track the thermal signals of asteroids for a more precise way at gauging their size.
Harnessing GPUs to Save the Planet From Asteroids
The 2024YR4 near-Earth asteroid — estimated as wide as 300 feet and capable of destroying a city the size of New York — has a 2.3% chance of striking Earth.
New Method for Detecting Small Asteroids
A new method for detecting small asteroids, developed by an international team of researchers, uses previous studies, asteroid synthetic movement tracking, and infrared observations. This method was applied to images of TRAPPIST-1, a star studied to search for signs of atmospheres around its seven terrestrial planets.
Conclusion
The new study used the JWST, the best-ever telescope in the infrared, on images of TRAPPIST-1, a star studied to search for signs of atmospheres around its seven terrestrial planets. The data include more than 10,000 images of the star. The researchers applied synthetic tracking methods, which doesn’t require previous information on an asteroid’s motion. Instead, it does "fully blind" search by testing possible shifts, like velocity vectors.
