Physicists Have Caught Electron Orbits in an Exciton Quasiparticle For The First Time

For the first time, scientists have managed to image the orbits of electrons within a quasiparticle known as an exciton - a result that has allowed them to finally measure the excitonic wave function describing the spatial distribution of electron momentum within the quasiparticle.

This achievement has been sought since the discovery of excitons in the 1930s, and while it may sound abstract at first, it could help in the development of various technologies, including quantum tech applications.

Ingenuity's 2nd flight will take place Thursday, April 22 at 09:30 UTC

The #MarsHelicopter will ascend to 5 meters, then move 2m sideways before coming to a stop, hovering in place, and making turns to point its color camera in different directions before heading back to its landing position. Images will arrive 4 hours later.

NASA's Perserverence Rover Generates Oxygen on Mars in Amazing First For Science

The six-wheeled robot has converted some carbon dioxide from the Martian atmosphere into oxygen, the first time this has happened on another planet, the space agency said Wednesday.

"This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate administrator for NASA's space technology mission directorate.

Not only can the process produce oxygen for future astronauts to breathe, but it could make hauling vast amounts of oxygen over from Earth to use as rocket propellant for the return journey unnecessary.

The #MarsHelicopter successfully completed its 2nd flight

It captured this image with its black-and-white navigation camera. It also reached new milestones of a higher altitude, a longer hover and lateral flying.

Astronomers Have Detected The Closest Black Hole to Earth. Thankfully, It's Tiny

Astronomers think they have discovered a tiny black hole, with a mass so small it places it in an exclusive category. Best of all, it's excitingly close by.

Roughly 1,500 light-years from our own planet, in a Milky Way constellation known as Monoceros, this is the closest black hole candidate to our planet scientists have yet had the fortune to find. 

The team at Ohio State University have named it the Unicorn - a hat tip to the black hole's home and its exceedingly rare nature.

Astronauts are about to launch on a used rocket, inside a used spacecraft

This Crew-2 mission is scheduled to launch from Kennedy Space Center at 09:49 UTC on Friday. Weather conditions appear favourable, but if there is an issue SpaceX, has a backup opportunity on Monday at 08:48 UTC
