No matter what, you do not want to find yourself near a neutron star.
These stellar beasts, made mostly of neutrons, are basically ultra-dense cosmic corpses roaming around space and, with incomprehensibly strong gravitational fields, torturing everything in their paths.
Ikea is adding to its smart home offerings with a tabletop air quality sensor that can detect particles smaller than 2.5 micrometers.
Vindstryka, Swedish for "wind force," can also monitor gaseous pollutants and changes in temperature and humidity. It will be available in April 2023 and will be compatible with Matter, the industry standard for smart home devices.
A single footprint can tell a story. A long time ago in the Jurassic era, around 166 million years ago, a jumbo meat-eating dinosaur strolled across what is now modern-day Yorkshire in England. At one point, it perhaps squatted down and then stood back up, leaving behind a truly epic footprint.
A team of researchers published a paper on the footprint in the Proceedings of the Yorkshire Geological Society on Thursday. The three-toed print measures in at 31 inches (80 centimeters) long. It's the largest of its kind ever found in Yorkshire. The owner of the foot was a carnivorous theropod, of which T. rex is a famous example.
Anker has recalled some of its 535 Power Bank products, citing possible overheating and fire risk as a safety hazard, according to a notice on the company's website.
The China-based electronics manufacturer said on its website that it discovered a "manufacturing condition" that impacted a small number of its 535 Power Banks -- specifically PowerCore 20K A1366 models -- and issued a voluntary recall on Jan. 18. The 535 Power Bank is a portable charger typically used for devices like laptops, tablets and smartphones during travel.
There are galaxies. Then there are galaxy clusters, which are made up of hundreds to thousands of galaxies held together by gravity. Then there are galaxy megaclusters -- a cluster of clusters, if you will. A new James Webb Space Telescope image reveals never-before-seen details of Pandora's Cluster, a megacluster where three galaxy clusters are merging.
Pandora's Cluster is already a cosmic superstar because of gravitational lensing, a phenomenon that allows astronomers to use a galaxy cluster like a giant magnifying glass to view more distant objects behind it. The new image is a team effort from Webb's infrared vision and the megacluster. NASA estimates there are 50,000 sources of infrared light in the view, including many faraway galaxies made visible by the lensing effect.
Anker recently recalled some of its 535 Power Bank products, citing possible overheating and fire risk as a safety hazard, according to a notice on the company's website.
