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…
Roughly 15 to 30 feet wide, the object will make its closest approach on September 24. A small near-Earth asteroid (or NEA) will briefly visit…
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…
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…
Solar Cycle 25 has begun. During a media event on Tuesday, experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) discussed their analysis…
Scientists used data gathered by NASA’s Cassini spacecraft during 13 years of exploring the Saturn system to make detailed images of the icy moon —…
Some of the most interesting places to study in our solar system are found in the most inhospitable environments – but landing on any planetary…
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…
