During a solar eclipse, astronomers who study heliophysics are able to study the Sun’s corona – its outer atmosphere – in ways they are unable to do at any other time. The brightest part of the Sun is so bright that it blocks the faint light from the corona, so it is invisible to most of the instruments astronomers use. …

NASA’s Europa Clipper probe checked out its radar as the spacecraft hurtled past Mars on the way to Jupiter’s moon Europa. The Mars flyby in March was primarily to use the planet’s gravitational pull to tweak the Europa Clipper’s trajectory. However, boffins were able to use the proximity of the planet to calibrate the spacecraft’s infrared camera and test its …

Here’s what you’ll learn when you read this story: Creating quantum entanglement from scratch can be tricky business, so researchers are exploring ways that entangled pairs can “share” these states amongst themselves. A new study shows how an entangled pair can pass on their entangled state to another pair by using particle interactions. Theoretically, this sharing could be done indefinitely, …

Skywatchers are in for a treat: The Perseid meteor shower—one of the brightest and most active of the year—is about to hit its peak, according to the American Meteor Society. The Perseids are an annual meteor shower that started in July, but astronomers expect the light show to be at its best between the evening hours of August 12 through …

The Earth’s rotation is randomly speeding up, and nobody is quite sure why. These speed ups, which have occurred several times over the last few years, haven’t had any effect on daily life, but they also haven’t gone unnoticed by science. Aug. 5 is the next date when the Earth’s rotation is expected to speed up, shortening the day by …

Abstract illustration of a quantum double-slit experiment. Credit: ZME Science/Midjourney. MIT physicists have recreated the most iconic experiment in quantum physics — this time with individual atoms acting as the slits and single photons barely grazing past. Their results have firmly answered a question that has lingered for nearly a century: Can we ever observe light’s particle and wave nature …

After more than three weeks without a powerful solar flare, the sun has suddenly ramped up its activity, firing off three M-class solar flares in less than 24 hours. While the sun has been popping off plenty of smaller C-class flares lately, Sunday’s M2.9 eruption at 10:01 a.m. EDT (1401 GMT) on Aug. 3 was the first M-class flare since …

Zoom image will be displayed Intensity maps of 3I/ATLAS from stacking datasets collected on the 4th (top row) and 29th (bottom row) of July 2025, showing no visible cometary tail. The arrows point the directions to the Sun, north, east, and the negative velocity vector of the comet as seen on the plane of the sky. (Image credit: Santana-Ros et …
