For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact.

The spectacularly colorful aurora borealis -- or northern lights -- that fills the sky in high-latitude regions has fascinated people for thousands of years. Now, a team of scientists has resolved one of the final mysteries surrounding its origin.

High performance computers are central to the quest to understand the sun's behavior and its role in space weather events. Scientists are using the Frontera supercomputer to improve the state-of-the-art in space weather forecasting. Researchers described the role of backstreaming pickup ions in the acceleration of charged particles in the universe, which play an important role in space weather.

Careful criminals usually clean a scene, wiping away visible blood and fingerprints. However, prints made with trace amounts of blood, invisible to the naked eye, could remain. Dyes can detect these hidden prints, but the dyes don't work well on certain surfaces. Now, researchers have developed a fluorescent polymer that binds to blood in a fingerprint -- without damaging any DNA also on the surface -- to create high-contrast images.

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

Sun-facing satellites monitor the Sun's ultraviolet (UV) light to give us advance warning of solar storms. But over the course of just a year or two, the metal filters in the detectors mysteriously lose their ability to transmit UV light. Now, scientists have found the first evidence indicating that carbonization is not the problem.

Since the introduction of plastic (polymer) banknotes in 2016, the number of counterfeit notes on the streets has increased, however, researchers have developed a novel technique called Polymer Substrate Fingerprinting, which identifies every banknote's fingerprint which is unique and unclonable.

Electrons arriving from the Sun are propelled by electrical energy generated as high as 30,000 kilometers above Earth, ultimately creating the dazzling displays of the northern and southern lights.

Analysis of observations made by satellites in 2014 has revealed a long-lasting 'space hurricane' -- a swirling mass of plasma several hundred kilometers above the North Pole, raining electrons instead of water.

The remarkable genetic scissors called CRISPR/Cas9, the discovery that won the 2020 Nobel Prize in Chemistry, sometimes cut in places that they are not designed to target.

The temporary breakdown of Earth's magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study shows.

New research has found that optical coherence tomography (OCT) imaging technology can be utilized to distinguish between legitimate and counterfeit travel documents.

In the Van Allen radiation belts, electrons can reach almost the speed of light. Researchers have revealed conditions for such strong accelerations. They had demonstrated in 2020: during solar storm plasma waves play a crucial role. However, it remained unclear why ultra-relativistic electron energies are not achieved in all solar storms. They now show: extreme depletions of the background plasma density are crucial.

Researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals -- everything from illicit drugs to pollution -- as quickly as a breathalyzer identifies alcohol.

Although stellar flares are typically viewed as a detriment to habitability, study shows 'life might still have a fighting chance.' Researchers find that flares drive a planets atmospheric composition to a new chemical equilibrium.
