An international team of astronomers led by researchers from the Leiden University has discovered a whirlwind of dust and pebbles in orbit around a young…
The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the…
A step in the search for life elsewhere in the galaxy. The huge forces generated by the Z machine at Sandia National Laboratories are being…
New study found that electrons can reach ultra-relativistic energies for very special conditions in the magnetosphere when space is devoid of plasma. Recent measurements from…
About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun’s tenuous outermost…
Cygnus X-1, a binary star system first discovered in 1964, comprises one of the closest black holes to Earth. New observations of this black hole,…
Meteorites Remember Conditions of Stellar Explosions A team of international researchers went back to the formation of the solar system 4.6 billion years ago to…
Laser-cooled plasma-in-a-bottle could answer questions about the sun, fusion power. Rice University physicists have discovered a way to trap the world’s coldest plasma in a…
Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in…
A study by the University of Southampton gives a new perspective on why our planet has managed to stay habitable for billions of years –…
Ever since the astronomer Edwin Hubble demonstrated that the further apart two galaxies are, the faster they move away from each other, researchers have measured…
A team of scientists has detected the presence of a high-energy neutrino—a particularly elusive particle—in the wake of a star’s destruction as it is consumed…
Astronomers now have evidence from two X-ray telescopes (Chandra and NuSTAR) for a key component of a famous supernova remnant. Supernova 1987A was discovered on…
The cosmic microwave background, or CMB, is the electromagnetic echo of the Big Bang, radiation that has been traveling through space and time since the…
The universe is expanding, and it expands a little faster all the time. Scientists call the speeding up of this expansion cosmic acceleration. This growth…
During a typical year, over a million people visit Yellowstone National Park, where the Old Faithful geyser regularly blasts a jet of boiling water high in…
Early observations of stars in the local universe will pave the way for years of discovery across a range of science topics The combination of…
