‘Monster’ Quake on Mars Is The Biggest Ever Recorded on Another Planet, NASA Says

'Monster' Quake on Mars Is The Biggest Ever Recorded on Another Planet, NASA Says

In terms of seismic events on the red planet (or indeed any other planet besides Earth), this is the biggest one recorded so far: the NASA InSight lander has recorded a ‘monster’ of a marsquake, which is estimated to have hit magnitude 5 on the scale used on Earth. That beats the previous record holder, … Read more

NASA ICON Finds Effects of Massive Tonga Volcanic Eruption Reached Space

Hunga Tonga Hunga Ha’apai Volcano Umbrella Cloud

The GOES-17 satellite captured images of an umbrella cloud generated by the underwater eruption of the Hunga Tonga-Hunga Ha’apai volcano on January 15, 2022. Crescent-shaped bow shock waves and numerous lighting strikes are also visible.

James Webb Space Telescope is ‘perfectly aligned,’ NASA says

James Webb Space Telescope is 'perfectly aligned,' NASA says

All four science instruments on NASA’s James Webb Space Telescope have achieved “perfect alignment” in advance of the telescope’s official debut this summer, project officials said in a news teleconference on Monday (May 9). “I’m delighted to report that the telescope alignment has been completed with performance even better than we had anticipated,” Michael McElwain, … Read more

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 … Read more

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

Simulation of Supermassive Black Hole Merger

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 … Read more

NASA’s InSight lander just detected the biggest quake on Mars

NASA's InSight lander just detected the biggest quake on Mars

The NASA InSight lander just detected the biggest quake ever found on another planet — a marsquake with a magnitude of 5 that took place on the red planet on May 4. “Since we set our seismometer down in December 2018, we’ve been waiting for ‘the big one,’” said Bruce Banerdt, InSight’s principal investigator at … Read more

A ‘mixed up’ sunspot just fired off a huge solar flare

A 'mixed up' sunspot just fired off a huge solar flare

Scientists are keeping an eye on a sunspot that fired off an X-class flare while “having an identity crisis,” according to SpaceWeather.com. Amplified aurora displays are possible if a coronal mass ejection of charged particles emerges from the “mixed-up” sunspot AR3006, which pointed its flaring blast toward Earth Tuesday (May 10) at 9:55 am EDT … Read more
