Lawrence Livermore National Laboratory released this update on researchers’ use of high performance computing resources to study the atmospheres of exoplanets, which are planets beyond our own solar system. The NASA/ESA/CSA James Webb ….
Calling AI experts! Join the Hunt for Exoplanets
July 5, 2022 by
Artificial Intelligence (AI) experts have been challenged to help a new space mission to investigate Earth’s place in the universe. The Ariel Data Challenge 2022, which launched on 15th June, is inviting AI and machine learning experts from industry and academia to help astronomers understand planets outside our solar system, known as exoplanets.
Extreme Computing for Extreme Adaptive Optics: The Key to Finding Life Outside our Solar System
August 15, 2018 by
Hatem Ltaief from KAUST gave this talk at PASC18. “The real-time correction of telescopic images in the search for exoplanets is highly sensitive to atmospheric aberrations. The pseudo-inverse algorithm is an efficient mathematical method to filter out these turbulences. We introduce a new partial singular value decomposition (SVD) algorithm based on QR-based Diagonally Weighted Halley (QDWH) iteration for the pseudo-inverse method of adaptive optics. The pseudo-inverse simulation code will be deployed on-sky for the Subaru telescope during observation nights scheduled early 2018.”
Video: How an Exoplanet Makes Waves
January 6, 2017 by
In this video, a new NASA supercomputer simulation depicts the planet and debris disk around the nearby star Beta Pictoris reveals that the planet’s motion drives spiral waves throughout the disk, a phenomenon that greatly increases collisions among the orbiting debris. Patterns in the collisions and the resulting dust appear to account for many observed features that previous research has been unable to fully explain.
