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).
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.
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.
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.
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.
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.
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.
Relativity Media has released a new featurette for its upcoming startle flick.
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 MESSENGER spacecraft recently completed its study of the planet Mercury which it orbited for one Earth-year.
Amelia Earhart's final flight is probably one of the longest enduring mysteries in the history of modern aviation.
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.
Astronomers have discovered a planet-like object circling a brown dwarf that appears to have formed much more quickly than was previously thought possible.
