Astronomers see a big boom when a black hole's magnetic field suddenly flips over

Astronomers see a big boom when a black hole’s magnetic field suddenly flips over

Two hundred thirty-six million light-years away, and hence 236 million years ago, a strange and intense light erupted from a distant astronomical object. The intergalactic rumble was detected here on Earth, where astronomers rapidly ascertained that the flare originated around a supermassive black hole. A spontaneous reversal of the black hole’s magnetic poles could be …

Simulation of Supermassive Black Hole Merger

Sizing Up the “Shadows” of Two Supermassive Black Holes in the Process of Colliding

In this simulation of a supermassive black hole merger, the blue-shifted black hole closest to the viewer amplifies the red-shifted black hole in the back through gravitational lensing. The researchers discovered a distinct dip in brightness when the closest black hole passed in front of the shadow of its counterpart, an observation that could be …

NASA's InSight lander detects largest 'marsquake' yet on Red Planet

NASA’s InSight lander detects largest ‘marsquake’ yet on Red Planet

NASA’s beleaguered InSight lander on Mars has detected a magnitude 5 “marsquake” — the largest one the spacecraft has felt yet since landing on the planet in November of 2018. It’s a major moment that comes during a fraught time for InSight, as the spacecraft’s solar panels continue to gather dust that will eventually bring …

James Webb Space Telescope's optical alignment "perfect," NASA says

James Webb Space Telescope’s optical alignment “perfect,” NASA says

Four-and-a-half months after the James Webb Space Telescope‘s Christmas Day launchingengineers have achieved near-perfect alignment of its complex optical system, setting the stage for final instrument calibrations and the release of the first showcase science images in July, officials said Monday. “I’m delighted to report that the telescope alignment has been completed with performance even …

Mars helicopter Ingenuity recovering from communications blackout

Mars helicopter Ingenuity recovering from communications blackout

Ingenuity appears to be in recovery from a communications glitch on Mars. NASA’s Jet Propulsion Laboratory (JPL) reestablished contact with the miniature Mars chopper Thursday (May 5) after it missed a scheduled call-in about two days before, the agency reported Friday (May 6). Engineers suggest that the helicopter may have entered a low power state …
