Better History Through X-Rays
Even if you aren’t a giant history buff, you probably know that the French royal family had some difficulties in the late 1700s. The end of the story saw the …read more Continue reading Better History Through X-Rays

Building An X-Ray Machine
While we typically encourage hackers to make their own tools or machines when practical, x-ray machines don’t usually make that list. Despite the risk of radiation, [William Osman] has done …read more Continue reading Building An X-Ray Machine
Bizarre repeating radio signal near galactic center may be brand new object
Astronomers have detected a strange radio source coming from somewhere near the center of the Milky Way galaxy. The signal repeats seemingly at random, and can’t be neatly attributed to any known astronomical object, leading the team to consider that i… Continue reading Bizarre repeating radio signal near galactic center may be brand new object
New type of supernova detected as stellar corpse kills companion star
Astronomers have spotted a new type of supernova for the very first time. An unlucky star seems to have prematurely exploded after colliding with an extremely dense object, perhaps a black hole or a neutron star, creating a unique signature in the sky….

X-ray echoes detected from behind a black hole for first time
Black holes are notoriously dark objects, but now Stanford astronomers have spotted some strange light coming from behind one. The X-ray echoes seem to be the result of the intense gravity of the object warping space and bending the light back around i… Continue reading X-ray echoes detected from behind a black hole for first time
Digital X-Ray Scanner Teardown Yields Bounty of Engineering Goodies
We’ll just go ahead and say it right up front: we love teardowns. Ripping into old gear and seeing how engineers solved problems — or didn’t — is endlessly fascinating, …read more Continue reading Digital X-Ray Scanner Teardown Yields Bounty of Engineering Goodies
Astronomers discover dying echoes of a supermassive black hole
Japanese astronomers have discovered the echoes of a “dying” supermassive black hole. While the object is quiet now, the team spotted the signatures of two huge radio jets that indicate it only recently fell silent after a bright, active phase.Continue… Continue reading Astronomers discover dying echoes of a supermassive black hole

Can I just say that doing a links roundup article in a week that includes April Fool’s Day isn’t a fun job? Because it’s not. I mean, how can you …read more Continue reading Hackaday Links: April 4, 2021
X-Ray Defeats Letterlocking — Unfolds and Reads Letter Sealed Since 1697
Over recent years we’ve been treated to a series of fascinating advances in the world of x-ray imaging, as researchers have developed their x-ray microtomography techniques and equipment to the point at which they can probe and then computationally reconstruct …read more

Smoking gun of rare “zombie star” supernova discovered in Milky Way
Astronomers have identified the remains of a rare type of supernova in our home galaxy for the first time. These events, known as Type Iax supernovae, occur when white dwarfs explode and may leave behind a “zombie star.”Continue ReadingCategory: Space,… Continue reading Smoking gun of rare “zombie star” supernova discovered in Milky Way
