Mars fungi could make red planet regolith fertile for crops

You’re on the fourth human mission to Mars, and you’ve been tasked with establishing the first self-sustaining food crop on a Martian settlement. You’re nervous because you’re using a new type of fungi called beneficial fungi, which you’re told will help enhance the Martian regolith, enabling it to be used for growing crops.

While growing crops on Mars using fungi might be decades away, this hasn’t stopped an international team of scientists from the United States and Brazil from pushing the limits of enhancing crop production through non-traditional methods.

With their findings published in the journal Frontiers in Astronomy and Space Sciences, the researchers discuss how ...

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

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 ...
