NASA InSight shutting down and more: Understand the world through 9 images

Posted by in category: cosmology

NASA is being forced to end its Mars lander mission early because of dust.


NASA’s InSight Mars lander is shutting down after four years and scientists have seen our galaxy’s black hole for the first time. Here’s May 11–18 in science images.

How could we find a wormhole hiding in the Milky Way?

Posted by in categories: cosmology, physics

If there was a wormhole in the center of our galaxy, how could we tell? Two physicists propose that carefully watching the motions of a star orbiting the Milky Way’s supermassive black hole might help scientists start to check. The researchers published the idea in a recent paper in the journal Physical Review D.

A wormhole is a hypothetical concept that connects two separate areas of space-time. Wormholes often appear in science fiction narratives like the 2014 film Interstellar as a convenient way to get from point A to point B in the vast universe. Physicists have many theories that describe how wormholes might behave, if they exist, but haven’t yet found any.

Hello darkness, my old friend 🎵

Want to listen to a black hole? The black hole at the center of the Perseus galaxy cluster sends out pressure waves that ripple the cluster’s gas, which we can translate into a note. #BlackHoleWeek https://go.nasa.gov/3MQae1I

Physicists Found a Way to Trigger The Strange Glow of Warp Speed Acceleration

Posted by in categories: cosmology, physics

Every time you take a step, space itself glows with a soft warmth.

Called the Fulling–Davies–Unruh effect (or sometimes just Unruh effect if you’re pushed for time), this eerie glow of radiation emerging from the vacuum is akin to the mysterious Hawking radiation that’s thought to surround black holes.

Only in this case, it’s the product of acceleration rather than gravity.
