Scientists may have found the source of the most powerful neutrino ever detected

Blazars May Explain Extreme Neutrino
The most energetic neutrino ever detected may have come from blazars — monstrous black holes shooting particle jets toward Earth from distant galaxies. The discovery could reveal cosmic accelerators far more powerful than scientists previously imagined. Credit: Shutterstock

A record-shattering particle from deep space may have exposed some of the universe’s most extreme black hole engines. A mysterious particle from deep space has scientists buzzing after the most energetic neutrino ever detected slammed through the Mediterranean Sea. Now, researchers think they may have identified the cosmic “culprits” behind it: blazars — supermassive black holes blasting jets of matter straight toward Earth.

Three years ago, scientists detected something extraordinary deep beneath the M...

Saturn-sized exoplanet with Earth-like temperature reveals methane-rich atmosphere

New research, led by astronomers at Penn State and the Jet Propulsion Laboratory, used NASA’s James Webb Space Telescope to analyze the atmosphere of a gas giant planet about the size of Saturn but with Earth-like temperatures and found it to be rich in methane. Credit: NASA/JPL-Caltech. All Rights Reserved.

A planet that is about the size of Saturn, but with a temperature more like Earth’s, has an atmosphere rich in methane, according to a new study using NASA’s James Webb Space Telescope (JWST).

Unlike the gas giant planets—Jupiter and Saturn—in Earth’s solar system, which are distant from the sun and therefore extremely cold, and so-called “hot Jupiters”—giant planets beyond the solar system that are s...

A hidden magnetic twist inside the Milky Way may rewrite what scientists know about how our galaxy is held together. Astronomers have uncovered a strange magnetic “flip” hidden inside the Milky Way. Using a new radio telescope, researchers mapped the galaxy’s magnetic field in unprecedented detail and discovered that a mysterious reversal in the Sagittarius Arm cuts diagonally across space. The finding could reshape how scientists understand the structure and future evolution of our galaxy.

For hundreds of years, astronomers have studied the night sky in an effort to understand ...

Innovative Mars rovers ‘swim’ through the sand

Some animals can move efficiently beneath granular surfaces. These include the sandfish (Scincus scincus), a lizard native to the Sahara. It can burrow into the sand and then literally “swim” through the desert sand to hunt or escape predators.

The principles of movement underlying this ability have only been understood for a few years. Researchers at the University of Würzburg have now translated the sandfish’s locomotion mechanism into an initial technical solution—an innovative Mars rover that outperforms other models when moving on sand.

The team led by computer scientist Marco Schmidt, Professor for Embedded Systems and...
