2024.05.06
Ever wonder what happens when you fall into a black hole? Now, thanks to a new, immersive visualization produced on a NASA supercomputer, viewers can plunge into the event horizon, a black hole’s point of no return. “People often ask about this, and simulating these difficult-to-imagine processes helps me connect the mathematics of relativity to […]
NASA/JAXA’s XRISM Mission Captures Unmatched Data With Just 36 Pixels
2024.04.30
At a time when phone cameras are capable of taking snapshots with millions of pixels, an instrument on the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) satellite captures revolutionary science with just 36 of them. “That may sound impossible, but it’s actually true,” said Richard Kelley, the U.S. principal investigator for XRISM at NASA’s Goddard […]
