NASA's InSight Mars lander may 'hear' Perseverance rover's landing next month

ByMike Wall
A detection would be a space-exploration first.

NASA asteroid probe stows space-rock sample for return to Earth

By Mike Wall
And that sample looks pretty big.

The left image shows OSIRIS-REx’s collector head hovering over the Sample Return Capsule (SRC) after the probe’s robotic arm moved it into the proper position for capture. The right image shows the collector head secured onto the capture ring in the SRC. Both images were captured by OSIRIS-REx’s StowCam camera.

Will our solar system survive the death of our sun?

By Paul Sutter

It's gonna get ugly.

"Our sun's death is a long way off — about 4.5 billion years, give or take — but someday it's going to happen, and what then for our solar system?

The trouble begins before the death proper: The first thing we have to contend with is the elderly sun itself. As the fusion of hydrogen continues inside the sun, the result of that reaction — helium — builds up in the core..."

Meet the zeptosecond, the shortest unit of time ever measured

By Stephanie Pappas
https://www.space.com/zeptosecond-shortest-time-unit-measured.html


Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule.

That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1.

A particle of light, called a photon (yellow arrow), produces electron waves out of an electron cloud (grey) of a hydrogen molecule (red: nucleus). The result of those interactions is what’s called an interference pattern (violet-white). The interference pattern is slightly skewed to the right, allowing researchers to calculate the time for the photon to get from one atom to the next.

Unless you are a real science geek the article below might make you go HUH???

Higgs boson possibly caught in act of never-before-seen transformation

By Rafi Letzter

"Scientists may have observed the Higgs boson doing a new trick: creating pairs of muons."

Why are galaxies different shapes?

By Donavyn Coffey

"Look into the night sky and you'll glimpse the stars from hundreds of billions of galaxies. Some galaxies are swirling blue disks like our own Milky Way, others are red spheres or misshapen, clumpy messes or something in between. Why the different configurations?"
