Latest the Astrophysical Journal Stories
IOP Publishing (IOP) and the American Astronomical Society (AAS) are pleased to announce the launch of the Astronomy Image Explorer (AIE).
Drs. Michael Hahn and Daniel Wolf Savin, research scientists at Columbia University's Astrophysics Laboratory in New York, NY, found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona and moreover that they also deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona.
The American Astronomical Society (AAS) supports President Barack Obama’s new policy on “open access,” the idea that published results of taxpayer-funded research should be made freely available on the Internet rather than permanently restricted to journal subscribers or other paying customers.
Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Earth, to create a beating pulse between the ground and the lower ionosphere, about 60 miles up in the atmosphere.
New research suggests that billions of stars in our galaxy have captured rogue planets that once roamed interstellar space.
One day in the fall of 2011, Neil Sheeley, a solar scientist at the Naval Research Laboratory in Washington, D.C., did what he always does – look through the daily images of the sun from NASA's Solar Dynamics Observatory (SDO).
The discovery of a dark matter mass left behind after what is being called a wreck between massive clusters of galaxies has experts questioning current theories regarding the invisible substance believed to make up more than 80% of the universe.
Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope.
Three planets -- each orbiting its own giant, dying star -- have been discovered by an international research team led by a Penn State University astronomer.
Supermassive black holes millions to billions times the mass of our Sun lie at the heart of most, maybe all large galaxies.
