A new study co-led by the Department of Earth and Planetary Sciences at The University of Hong Kong (HKU) and the Department of Atmospheric and Oceanic Sciences at the University of California, Los Angeles (UCLA) reveals that plasma waves traveling along Earth’s magnetic field lines act like an invisible power source, fueling the stunning auroral displays we see in the sky.

What part of Orion is this?

Auroras, shimmering bands of light that shoot through the night sky near the Earth’s poles, can follow patterns known as arcs

NASA’s SpaceX Crew-12 mission is preparing to launch for a long-duration science mission aboard the International Space Station. During the mission, select crew members will participate in human health studies focused on understanding how astronauts’ bodies adapt to the low-gravity environment of space, including a new study examining subtle changes in blood flow.

I always say that one of the things that separates real science from pseudoscience is that while in both you’re allowed to say whatever crazy idea pops into your mind, in real science you’re obligated to take that idea seriously.

For almost two decades, scientists have debated whether sponges or comb jellies represent the first animal lineage. Now some are calling for a more harmonious approach

Prime numbers have fascinated humankind for generations—here are three of the most intriguing primes

The decorated Olympic skier has had numerous injuries and a partial knee replacement but still plans to go for the gold at the 2026 Winter Olympics

Watching sporting events like the Super Bowl can influence our brains and bodies—and not always in a good way

Strange as it may seem, the prospects of finding advanced high-tech aliens somewhere in the cosmos will likely depend on finding exoplanets that like our own earth harbor large amounts of accessible energy-dense coal.

An international team of researchers have published two papers that reveal a new model for how the magnetic field of the Milky Way evolved.

Preliminary studies suggest that a high-fat, low-carbohydrate diet could reduce schizophrenia symptoms in some people, but claiming it’s a cure is misleading, experts say

Recently published data from the Event Horizon Telescope (EHT) of the galaxy Messier 87 facilitate new insights into the direct environment of the central supermassive black hole. Measured differences in the radio light on different spatial scales can be explained by the presence of an as of yet undetected jet at frequencies of 230 Gigahertz at spatial scales comparable to the size of the black hole. The most likely location of the jet base is determined through detailed modeling.

NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash toward the upper middle — on Feb. 4, 2026. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in blue and red.

After 25 years, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider—the U.S.’s largest and only particle collider—has ceased operations, but its science lives on

The upcoming drugs CagriSema and retatrutide target multiple gut hormones and could cause twice as much weight loss than current treatments. But experts wonder how much is too much

Isn’t the FLRW metric way generic? It lays out the basic assumptions and tells us how the universe should behave, but it doesn’t say WHAT the universe is made of.

The flow of ice at Pine Island Glacier in West Antarctica has sped up dramatically due to the disintegration of the ice shelf in front of it, and this could lead to faster sea level rise
