The tempests on Saturn, which can grow into bright bands that encircle the entire planet, are on a natural timer that is reset by each subsequent storm.
New studies have calculated the amount of water in these central latitudes, and it is the equivalent of all of Mars being covered by more than 1 meter of ice.
Differences in morphology and color across the surface suggest the dwarf planet was once an active body.
Scientists have found that the while the Sun formed 5 billion years ago, the peak of star formation out galaxy likely occurred 5 billion years earlier.
A crucial difference in the “fingerprints” of Earth and the Moon confirms an explosive, interconnected past.
The discovery reveals that the protoplanetary disk surrounding the million-year-old star MWC 480 is brimming with methyl cyanide.
This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth’s atmosphere.
Observation results show the presence of multiple gas outflows from a protostar, indicating the possible existence of two newborn stars in the region.
Forged by the chance alignment of two distant galaxies, this striking ring-like structure is a rare and peculiar manifestation of gravitational lensing.
To understand how stars explode, astronomers are studying the debris in detail with sensitive instruments.
This winter, some members of the rover team were busy analyzing the martian atmosphere for xenon, a heavy noble gas.
The glowing filaments indicate that these active galaxy cores were once emitting more energy or changed very rapidly, which they weren’t supposed to do.
Scientists believe non-gaseous planets are as prevalent around binaries as around single stars.
Out of more than 15 entries, the St. Louis Astronomical Society wins Astronomy’s annual award honoring astronomy outreach programs.
By studying a young star in images 18 years apart, scientists have been able to see exactly what their models predicted.
A recent study shows that RR Lyrae stars may not be as lonely as previously thought.
Pinpointing when and how they formed should provide insight into the process of galaxy cluster evolution, including the role played by dark matter in shaping these cosmic metropolises.
Cassini’s orbits had carried it high above the planet’s poles over the past two years, during which the mission’s ability to encounter the moons, apart from Titan, was limited.
A new study suggests carbon from comets breaking apart acts like a stealth darkening agent on the innermost planet.
Even though cosmic magnetic fields are much weaker than Earth's magnetic field, they have an important effect in regulating how stars form.
