Mystery of planet-forming disks explained by magnetism

Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.

NASA's NuSTAR untangles mystery of how stars explode

One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR).

Van Allen probes shed light on decades-old mystery

New research using data from NASA's Van Allen Probes mission helps resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment, and is likely to influence our understanding of planetary magnetospheres throughout the universe.

Scientists solve a decades-old mystery in the Earth's upper atmosphere

New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe.

The mystery of neutron stars heats up

Until now, scientists were pretty sure they knew how the surface of a neutron star – a super dense star that forms when a large star explodes and its core collapses into itself – can heat itself up. However, research by a team of scientists led by a Michigan State University physicist has researchers rethinking that theory.

Newly discovered flux in the Earth may solve missing-mantle mystery

It's widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the sun, gathering in rocky clumps to form asteroids. These asteroids, gaining momentum, whirled around a fledgling solar system, repeatedly smashing into each other to create larger bodies of rubble — the largest of which eventually cooled to form the planets.

Scientists solve a 14,000-year-old ocean mystery

At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended — as mysteriously as it began — just a few hundred years later.

Video: The mystery of spiral galaxies and their enigmatic arms

Our very own Milky Way is likely a spiral galaxy. Indeed, our solar system and Earth reside somewhere near one of its filamentous, swept-back arms.

House at the End of the Street featurette talks to the girl

Relativity Media has released a new featurette for its upcoming startle flick.

Amelia Earhart's airplane may have been found

The fate of Amelia Earhart and her stalwart navigator Fred Noonan has been a haunting American mystery since the duo disappeared way back in 1937.

The mystery of Mercury’s core

The MESSENGER spacecraft recently completed its study of the planet Mercury which it orbited for one Earth-year.

Search resumes for Amelia Earhart's plane

Amelia Earhart's final flight is probably one of the longest enduring mysteries in the history of modern aviation.

NASA solves ancient supernova mystery


NASA telescopes have helped solved an ancient mystery that began nearly 2,000 years ago when Chinese astronomers witnessed what turned out to be an exploding star in the sky.

Hubble discovers mystery object orbiting brown dwarf

Astronomers have discovered a planet-like object circling a brown dwarf that appears to have formed much more quickly than was previously thought possible.
