Three different meteor showers are happening at the same time this month, giving skywatchers plenty of chances to spend their summer nights looking for shooting stars. The annual alpha Capricornids, the Southern delta Aquariids and the Perseid meteor showers are all currently active, with each celestial show set to last through mid-August. Here’s what to know about these meteor showers, …

Recent shifts in Earth’s magnetic field have human fingerprints all over them. While it is normal for our planet’s magnetic poles to sporadically wander, new research shows we’ve now amassed enough water behind dam walls to account for at least some of the current movements. Harvard University geophysicist Natasha Valencic and colleagues calculated that the masses concentrated in just under …

In a significant leap for agricultural science, Chinese researchers have unveiled a new variety of rice that could dramatically change the way we approach global food production. This newly developed rice is not just any crop—it’s a game-changer, engineered to thrive on land that was previously thought to be unusable. In fact, the new strain holds the promise of growing …

In the center of our galaxy, gigantic, balloon-like structures of high-energy radiation extend thousands of light-years above and below the Milky Way’s plane. Known as the Fermi bubbles, the massive lobes may have been the result of a violent outburst in our galaxy’s recent past. A new discovery of cold hydrogen clouds embedded inside the bubbles adds another level of …

A hydrothermal explosion has created a 13-foot blue water feature in Yellowstone National Park. The explosion appears to have happened between December 2024 and May 2025.  While rare, hydrothermal explosions can result in injuries or death to humans and animals.  A brand-new discovery in a popular national park has “explosive” beginnings. Geologists in Yellowstone National Park recently discovered a new …

A NASA Mars mission’s long and winding road to the launch pad is nearing its end. The twin ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) Mars probes had been scheduled to launch last October, on the first-ever flight of Blue Origin‘s huge, partially reusable New Glenn rocket. But NASA took the two spacecraft off that flight in September, citing …

Sharks can be formidable predators, but when they’re flipped upside down, many species enter a trance-like state, known as tonic immobility, and are as helpless as a beetle on its back. Tonic immobility is “as close to hypnotising a shark as you can get!” Joel Gayford, a doctoral candidate of marine ecology at James Cook University in Australia, told Live …

If you want to capture the majesty of the Sun, you should probably ask an artist, but if you want to capture its raw power, that’s a job for a robot. While generations of artists have painted or photographed sunsets and poets have written sonnets to the Sun, NASA’s Parker Solar Probe (PSP) just sent back the closest solar snapshots …
