Mirach is guide star to 3 galaxies

Mirach, a bright star in the constellation Andromeda, is often used by stargazers to locate the Andromeda Galaxy, the Triangulum Galaxy, and a galaxy known as Mirach’s Ghost (NGC 404). Source: https://earthsky.org/brightest-stars/mirach-guide-star-to-three-galaxies…

The first demonstration of braiding in photonic topological zero modes

Physics theory suggests that exotic excitations can exist in the form of bound states confined in the proximity of topological defects, for instance, in the case of Majorana zero modes that are trapped in vortices within topological superconducting materials. Better understanding these states could aid the development of new computational tools, including quantum technologies. …

Radar reveals 3 more subsurface polar lakes on Mars

Scientists with the European Space Agency say that the Mars Express orbiter has found evidence of three more salty lakes below Mars’ south pole. The discovery comes two years after the first lake was detected in 2018. Source: https://earthsky.org/space/3-more-subsurface-lakes-mars-south-pole…

Finding vaporized metal in the air of an exoplanet

WASP-121b is an exoplanet located 850 light years from Earth, orbiting its star in less than two days—a process that takes Earth a year to complete. WASP-121b is very close to its star—about 40 times closer than Earth to the Sun. This close proximity is also the main reason for its immensely high temperature of around 2,500 to 3,000 degrees Celsius….

Meet the Pi planet. It orbits its star every 3.14 days

In a fun cosmic coincidence, researchers used old Kepler spacecraft data to discover an Earth-sized exoplanet with an orbital period of 3.14 days, a number that matches the mathematical constant pi. Source: https://earthsky.org/space/pi-exoplanet-k2-315b-has-3-14-day-orbit…

A Utah Company Claims It Invented Contact Tracing Tech

In the fight against Covid-19, contact tracing apps have so far largely been disappointments — in the United States, at least. Proposed in the spring as a way to help quickly stifle viral outbreaks by tracking down potential exposures using smartphones, they were stunted by technical glitches, concerns over privacy, and the US’s fragmented, haphazard pandemic response. Now, they may become…

Amazon Plans To Put 1,000 Warehouses In Suburban Neighborhoods

An anonymous reader quotes a report from Bloomberg: Amazon plans to open 1,000 small delivery hubs in cities and suburbs all over the U.S., according to people familiar with the plans. The facilities, which will eventually number about 1,500, will bring products closer to customers, making shopping online about as fast as a quick run to the store. It will also…

Martian Moons eXploration spacecraft to take ultra-high definition images of Mars via 8K camera

The Japan Aerospace Exploration Agency (JAXA) and Japan Broadcasting Corporation (NHK) have decided to jointly develop the Super Hi-Vision Camera that is capable of filming 4K and 8K images in space for JAXA’s Martian Moons eXploration (MMX) mission. This would be the first time in history that 8K ultra-high-definition images of Mars and its moons are taken in proximity. By combining…

Amazon Drivers Are Hanging Smartphones in Trees To Get More Work

A strange phenomenon has emerged near Amazon.com delivery stations and Whole Foods stores in the Chicago suburbs: smartphones dangling from trees. Contract delivery drivers are putting them there to get a jump on rivals seeking orders, Bloomberg reported Tuesday. From a report: Someone places several devices in a tree located close to the station where deliveries originate. Drivers in on the…

Attention Rogue Drone Pilots: AI Can See You

schwit1 quotes IEEE Spectrum:
The minute details of rogue drone’s movements in the air may unwittingly reveal the drone pilot’s location — possibly enabling authorities to bring the drone down before, say, it has the opportunity to disrupt air traffic or cause an accident. And it’s possible without requiring expensive arrays of radio triangulation and signal-location antennas. So says a team of…
