How neutron imaging uncovers hidden secrets of fossils and artifacts
The technique can complement X-ray scanning and other tools to uncover details of dinosaur fossils, mummies and more.
- Planetary Science
Marsquakes and meteorite hits show Mars has a dense liquid metal core
Mars’ dense liquid iron core is wrapped in a layer of molten rock, which threw off previous measurements of the Red Planet’s heart.
- Physics
How quantum ‘squeezing’ will help LIGO detect more gravitational waves
An upgrade to LIGO that comes from exploiting a quantum rule known as the Heisenberg uncertainty principle makes it easier to detect spacetime ripples.
- Space
Here’s how citizen scientists can help during the 2024 solar eclipse
The sun will be near the peak of its activity cycle during the eclipse on April 8, 2024, making it a great time to crowdsource solar research.
- Space
NASA’s first look at a sample from asteroid Bennu reveals life’s building blocks
Scientists have begun to analyze roughly 250 grams of Bennu, which could offer insight into solar system formation and life’s origins on Earth.
- Physics
Technique to see the ultrafast world of electrons wins 2023 physics Nobel
Physicists Pierre Agostini, Ferenc Krausz and Anne L’Huillier won for work creating light bursts that last billionths of a billionth of a second.
- Cosmology
New JWST images suggest our understanding of the cosmos is flawed
JWST data don’t resolve a disagreement over how fast the universe is expanding, suggesting we might need strange new physics to fix the tension.
- Space
NASA’s OSIRIS-REx has returned bits of the asteroid Bennu to Earth
Asteroid dirt from Bennu could help reveal clues about the material that came together to make the solar system — and possibly where life comes from.
- Physics
Centuries on, Newton’s gravitational constant still can’t be pinned down
A new experiment could finally answer the question 'What is the strength of gravity?' But it's a hard test to do.
- Physics
Neutrinos offer a new view of the Milky Way
Physicists turned to AI to help map out the newfound origins of ghostly neutrino particles coming from deep in the Milky Way.
- Physics
Physicists split bits of sound using quantum mechanics
New experiments put phonons — the tiniest bits of sound — into quantum mechanical superpositions and show they are as weird as other quantum entities.
- Astronomy
The Parker Solar Probe may have spotted the origin of high-speed solar winds
Kinks in the magnetic fields near the surface of the sun appear to be the cause of fast-moving flows in the solar wind.
