Ghostly

TUTORIALExplore the mysteries of quantum computing!Source: Stable Diffusion.Whenever I learn a new programming language or framework, I often find myself trying to program a game as a first try at using the various features of the platform.In the case of quantum computing, creating the beginnings of a game in order to learn the concepts is absolutely perfect.Now, quantum computing has a range of topics and features to learn. These may include how qubits are made, how qubits are manipulated, the various gates, but the…

Ghost imaging is a sophisticated and incredibly useful set of techniques that scientists deploy to photograph light-sensitive objects in surprisingly high resolution.By making use of a mix of quantum and classical phenomena to pull visual information from just one of a pair of entangled photons, the method can capture images where energetic rays of light or radiation risk damaging the material of interest.A new study has revealed a way of improving ghost imaging without adding much to its cost or complexity. In simple…

via Vertical Entertainment War movies and horror films are two of the most reliably performing genres on streaming, so when you put the two of them together like writer and director Eric Bress did in 2020’s Ghost of War, then subscribers are virtually obligated to check it out. True to form, the World War II story with an intriguing supernatural slant has become one of the most-watched titles on the Starz global rankings this weekend, per FlixPatrol. It’s easy to see why on-demand audiences would be so keen to…

When most people learn about the structure of the universe at school, the model is simple: planets rotate around stars, and stars cluster together in galaxies, of which there are many in the universe. You might even have learned that galaxies can often group together by the thousand in enormous galaxy clusters. However, there are both rogue planets and rogue stars out there, that wander the universe unattached to larger structures. Recently, the Hubble Space Telescope has been used to investigate wandering stars that…

Researchers using data from the Hubble Space Telescope have made a strange discovery: a “ghostly light” surrounding our solar system. When light from stars, planets, and even the glow of starlight scattered by dust is accounted for, there’s still some “extra” light observed and astronomers are trying to work out where it’s coming from. The researchers looked at 200,000 Hubble images in a project called SKYSURF, looking for any excess of light beyond that coming from know sources. And they did find a consistent, faint…

Yet an eerie glow comes from the walls, ceiling, and floor. The faint light is barely enough to see your hands before your face, but it persists.Sounds like a scene out of “Ghost Hunters?” No, for astronomers this is the real…

A new analysis of Hubble data has clinched it: There's too much light in the space around the Solar System.Not much extra light, to be sure. Just a subtle, ghostly glow, a faint excess that can't be accounted for in a census of all the light-emitting objects.All the stars and galaxies surrounding the Solar System – and zodiacal light, aka dust on the Solar System's plane – none of these can explain what astronomers are now calling "ghost light".After analyzing 200,000 Hubble images and taking thousands of measurements in…

Hubble image of the spiral galaxy NGC 1068. Credit: NASA / ESA / A. van der HoevenEvidence of high-energy neutrino emission from the galaxy NGC 1068 has been found by an international team of scientists for the first time. First spotted in 1780, NGC 1068, also known as Messier 77, is an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date. Located 47 million light-years away from us, this galaxy can be observed with large binoculars. The results, to be published today…

When a massive star runs out of fuel and comes to the end of its life, it can explode in an enormous and epic event called a supernova, which can be as bright as an entire galaxy. These explosions can obliterate anything around them, but they aren’t simply destructive — they can also create stunning structures called supernova remnants. These remnants are formed as shock waves from the explosion travel through nearby clouds of gas, sculpting them into beautiful shapes. One such ghostly remnant has been captured by a…
