Global Maps of the Solar Corona Magnetic Field Created for the First Time
The Sun is a magnetized star. Its magnetic field is essentially three dimensional and it occupies all layers of the solar atmosphere. However, routine measurements…
ALMA Reveals Magnetic Fields in the Early Stages of Massive Star Formation
Star formation in molecular clouds usually occurs in a two-step process. Supersonic flows first compress the clouds into dense filaments light-years long, after which gravity…
Scientists Analyze Sunquakes: Can Ripples on the Sun Help Predict Solar Flares?
Scientists analyze sunquakes to pinpoint flare energy source, perhaps predict flare severity. Solar flares are violent explosions on the sun that fling out high-energy charged…
Astronomers Discover “One of a Kind” Glow Surrounding Comet – Ultraviolet Atomic Emissions
An atmospheric light show previously relegated to planets and Jupiter moons is found on comet using data from ESA’s Rosetta spacecraft. Data from NASA instruments…
Cosmic X-Rays Reveal a Distinctive Signature of Black Hole Event Horizons
An international team of astrophysicists has found a distinctive signature of black hole event horizons, unmistakably separating them from neutron stars — objects, comparable to…
Seeing the Dark Regions of the Universe: The Cold Case of Carbon Monoxide
Fifty years ago, astronomers discovered carbon monoxide in space. It allowed us to see dark regions of the universe, and helped us understand it more…
Stellar Phosphorus Guides Search for Potentially Habitable Exoplanets
Stellar chemical compositions used as proxy for potentially habitable systems. A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing…
Popular Theory About the Early Solar System Called Into Doubt by Meteorite Evidence
It is generally accepted that the inner region of the early solar system was subject to an intense period of meteoric bombardment referred to as…
