Astronomers find new details in first known spiral galaxy
Case Western Reserve University astronomers peered deep into space to discover new features of a galaxy that's been sketched and photographed for 170 years.
Image: XMM-Newton and Hubble view of Jupiter's ghost
Names of astronomical objects are often ambiguous, especially when the historical designation of a certain class of celestial body preceded their physical understanding and was based on their appearance in ...
Nuclear pasta may offer insight into strange world of neutron stars
An infrared atlas of interacting galaxies
Most galaxies, including our own Milky Way, have been influenced by an interaction with another galaxy at some time in their past. Interactions between galaxies can trigger an increase in star-formation activity ...
'Live fast, die young' galaxies lose the gas that keeps them alive
Galaxies can die early because the gas they need to make new stars is suddenly ejected, research published today suggests.
The tell-tale signs of a galactic merger
The NASA/ESA Hubble Space Telescope has captured this striking view of spiral galaxy NGC 7714. This galaxy has drifted too close to another nearby galaxy and the dramatic interaction has twisted its spiral ...
Some potentially habitable planets began as gaseous, Neptune-like worlds
Two phenomena known to inhibit the potential habitability of planets—tidal forces and vigorous stellar activity—might instead help chances for life on certain planets orbiting low-mass stars, University ...
NASA engineer advances new daytime star tracker
Scientists who use high-altitude scientific balloons have high hopes for their instruments in the future. Although the floating behemoths that carry their instruments far into the stratosphere can stay aloft ...
Will NASA's TESS spacecraft revolutionize exoplanet hunting?
NASA's Transiting Exoplanet Survey Satellite (TESS), planned to be launched in August 2017 on a SpaceX Falcon 9 rocket from the Cape Canaveral Air Force Station, Florida, is designed to discover thousands ...
Stellar astronomers answer question posed by citizen scientists: 'What are yellowballs?'
Some four years ago, a citizen scientist helping the Milky Way Project study Spitzer Space Telescope images for the tell-tale bubble patterns of star formation noticed something else.
Black hole chokes on a swallowed star
A five-year analysis of an event captured by a tiny telescope at McDonald Observatory and followed up by telescopes on the ground and in space has led astronomers to believe they witnessed a giant black hole ...
Cosmic puzzle settled: Comets give us shooting stars
Suspicions that shooting stars come from comet dust, transformed into fiery streaks as they hit Earth's atmosphere, have been bolstered by Europe's Rosetta space mission, scientists reported Monday.
The cosmic chemistry that gave rise to water
Earth's water has a mysterious past stretching back to the primordial clouds of gas that birthed the Sun and other stars. By using telescopes and computer simulations to study such star nurseries, researchers ...
Are aliens watching old TV shows?
You've probably heard the trope about how aliens have been watching old episodes of "I Love Lucy" and might think these are our "historical documents". How far have our signals reached?
