Survey of geosynchronous orbital debris led by University of Warwick found over 75% of debris detected could not be matched to known objects in public…
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…
When galaxies collide, it’s as if all the players in a symphony have begun a furious crescendo: As their stars and gas fall toward the…
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 to pinpoint flare energy source, perhaps predict flare severity. Solar flares are violent explosions on the sun that fling out high-energy charged…
In an interplanetary faux pas, it appears some pieces of asteroid Vesta ended up on asteroid Bennu, according to observations from NASA’s OSIRIS-REx spacecraft. The…
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…
NASA’s IRIS Spots Nanojets: Shining Light On Heating the Solar Corona In a paper published today (September 21, 2020) in Nature Astronomy, researchers report the…
An international team of astrophysicists has found a distinctive signature of black hole event horizons, unmistakably separating them from neutron stars — objects, comparable to…
In the aurora borealis on Earth, electrically charged particles of the solar wind move along the Earth’s magnetic field. At high latitudes, these strike nitrogen…
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…
Resting on the tail of the Great Bear in the constellation of Ursa Major, lies NGC 5585, a spiral galaxy that is more than it…
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…
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…
An international team of astronomers recently announced the discovery of a rare molecule — phosphine — in the clouds of Venus. On Earth, this gas…
The violent events leading up to the death of a star would likely drive away any planets. The newly discovered Jupiter-size object may have arrived…
Understanding the Sun’s behavior is an important part of life in our solar system. Scientists use several indicators to track solar cycle progress. Credit: NASA’s…
A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky…
