Astronomers Are Homing in on The Colossal Feeding Processes of Huge Black Holes
The more we study the Universe, the more it seems likely that each galaxy is orbiting a cosmic colossus - a supermassive black hole, powering the galactic nucleus.
Mind-Bending NASA Visualization Shows The Wild Warping of Binary Black Holes
Although it's extremely difficult to directly image the shadow of and the space around a black hole, that's not the only tool astronomers have in their kit.
Fascinatingly, simulations came very close to what we saw when a huge international team of scientists finally captured a direct image of a supermassive black hole, the now-famous M87*.
Because of the intense gravitational fields involved, stuff gets really whack. Light bends and its intensity changes, depending on which direction it's moving. So what happens when there's not one, but two black holes locked in mutual orbit, each with its own gravity, and each orbited by its own glowing accretion disk of dust and gas?
Well, it might look a little something like the latest, extremely trippy black hole visualization from NASA.

A pair of orbiting black holes millions of times the Sun’s mass perform a hypnotic dance in this NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas – called an accretion disk – that surrounds each one.

NASA is developing a plan to build an Arecibo-like telescope on the moon
NASA is funding research into how a radio telescope could be built on the far side of the moon. It could function similarly to the Arecibo telescope, which collapsed in December.
A lunar telescope could hear radio waves from the early universe that Earth-based telescopes can't as such a telescope would be shielded from the cacophony of radio signals that such a device on Earth would hear from all kinds of equipment and satellites.

This Is The Point When People Start Trusting Algorithms More Than Other Humans
Algorithms can help us with everything, from choosing what music to listen to next to finding the cheapest flight online. Now, new research reveals one of the tipping points that tend to make us trust a computer's judgment rather than a human's.

NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet.
Ingenuity took this shot of its shadow while hovering over the Martian surface. It used its navigation camera, which autonomously tracks the ground during flight.
The Ingenuity team at the agency’s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from the helicopter via NASA’s Perseverance Mars rover at 10:46 a.m. UTC
“Ingenuity is the latest in a long and storied tradition of NASA projects achieving a space exploration goal once thought impossible,” said acting NASA Administrator Steve Jurczyk. “The X-15 was a pathfinder for the space shuttle. Mars Pathfinder and its Sojourner rover did the same for three generations of Mars rovers. We don’t know exactly where Ingenuity will lead us, but today’s results indicate the sky – at least on Mars – may not be the limit.”

First Video of NASA's Ingenuity Mars Helicopter in Flight
In this video captured by NASA’s Perseverance rover, the agency's Ingenuity Mars Helicopter took the first powered, controlled flight on another planet
Stitched together from multiple images, the mosaic is not white balanced; instead, it is displayed in a preliminary calibrated version of a natural-color composite, approximately simulating the colors of the scene as it would appear on Mars
The solar-powered helicopter first became airborne at 7:34 a.m UTC – 12:33 Local Mean Solar Time (Mars time) – a time the Ingenuity team determined would have optimal energy and flight conditions. Altimeter data indicate Ingenuity climbed to its prescribed maximum altitude of 3 meters and maintained a stable hover for 30 seconds. It then descended, touching back down on the surface of Mars after logging a total of 39.1 seconds of flight.

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.Article

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.
