Summer is here, and if you have been planning to spend more time outdoors, a portable solar panel can be a great investment. These can keep your power stations charged wherever the sun shines, but not all solar panels are made equal. Some Reddit users have even been considering adding portable solar panels to their emergency backpacks, so that they don't lose power in the event of a disaster. CNET's current favorite is the Jackery SolarSaga 200, thanks to its lightweight and sizable solar-charg

Creating fair dice from random objects

What if you could make your dice any shape at all—not just boxes and polyhedra, but dragons or other game-relevant shapes? Most people are familiar with conventional cubical six-sided dice, but there are also polyhedral versions like the 20-sided dice used in ancient Rome and to play Dungeons and Dragons. Researchers have figured out how to design dice with even more exotic shapes, like a kitten, a dragon, or an armadillo. And they are "fair" dice: Experiments with 3D-printed versions produced

Forecasters to Lose Hurricane Satellite Data at the Worst Possible Time

gizmodo.com Ellyn Lapointe 2026-02-19 15:25:10

In one month, the National Oceanic and Atmospheric Administration (NOAA) and its National Hurricane Center (NHC) will lose access to critical satellite data that lets meteorologists see inside the eye of a storm. This marks the latest blow to the agency’s forecasting abilities as hurricane season gets underway. In an abrupt move that blindsided meteorologists and public officials on Wednesday, June 25, the Navy’s Fleet Numerical Meteorology and Oceanography Center (FNMOC) announced it was shutt

A critical US atmospheric data collection program will be halted by Monday, giving weather forecasters just days to prepare, according to a public notice sent this week. Scientists that the Guardian spoke with say the change could set hurricane forecasting back “decades”, just as this year’s season ramps up.

Astronomers usually keep their eyes on the sky, but on Monday, June 23, the community turned its attention toward Washington, D.C., as scientists from the Vera C. Rubin Observatory unveiled the telescope’s first images. Many have waited more than 20 years to see Rubin in action, and its initial findings did not disappoint.

What just happened? The James Webb space telescope has captured what is likely to be the first exoplanet discovered using the advanced observatory. An international team of astronomers uncovered the planet candidate in the debris field surrounding TWA 7, a low-mass star in the constellation Antlia that is located around 111 light-years away from Earth. They used Webb's mid-infrared instrument to suppress the overwhelming glare from the host star, revealing faint objects that would have been too

NASA’S James Webb Space Telescope has captured its first direct image of an exoplanet

engadget.com Unknown 2026-02-27 20:23:48

NASA’S James Webb Space Telescope has captured direct images of a planet outside of our solar system, which is the first time it has accomplished such a feat. This is a very big deal because exoplanets don't put out much light, so researchers typically discover new planets through indirect methods like keeping track of shadows as they pass across a host star. Webb, however, didn't have to do all that. It has directly captured images of a planet called TWA 7 b . Scientists believe the planet is

Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

This story originally appeared on Vox and is part of the Climate Desk collaboration. Odorless and colorless, methane is a gas that is easy to miss—but it’s one of the most important contributors to global warming. It can trap up to 84 times as much heat as carbon dioxide in the atmosphere, though it breaks down much faster. Measured over 100 years, its warming effect is about 30 times that of an equivalent amount of carbon dioxide. That means that over the course of decades, it takes smaller a
