NASA’s Cassini spacecraft observed Saturn’s ring system in unprecedented detail, and a team of planetary researchers from the University of California...
In the final phase of NASA’s Cassini mission, the spacecraft dived between Saturn and its innermost ring, at altitudes 1,616-2,423 miles (2,600-3,900...
Extrasolar ‘Neptunes’ are exoplanets with masses and radii similar to those of the ice giants in the Solar System. In 2015, astronomers using the NASA/ESA...
An international team of astronomers has detected helium escaping from the upper atmosphere of HAT-P-11b, a Neptune-mass exoplanet located in the constellation...
Since September 13, 2018, ESA’s Mars Express spacecraft has been observing the evolution of a water ice cloud formation hovering in the vicinity of Arsia...
Cassini’s 20-year mission culminated in a series of wild orbits. First, it grazed the outer rim of Saturn’s rings and then, in the Grand Finale phase,...
When NASA’s Cassini spacecraft arrived at Saturn in 2004, the gas giant’s southern hemisphere was enjoying summertime, while the northern was in the...
Astronomers have largely assumed that water-world exoplanets would not support the cycling of minerals and gases that keeps the climate stable on Earth,...
Recently, the scientific community stumbled upon a rare atmospheric phenomenon called Strong Thermal Emission Velocity Enhancement (STEVE) that has been...
Astronomers have detected atomic iron and titanium in the atmosphere of KELT-9b, a gas giant exoplanet orbiting a star in the constellation Cygnus, about...
A team of researchers from the Australian National University and the Lawrence Livermore National Laboratory has solved the mystery underlying Jupiter’s...
Recent observations by NASA’s space telescopes of ultrahot Jupiter-like exoplanets have surprised astronomers. The spectra of these planets have suggested...
On Mars, the atmospheric pressure is around 0.6% of Earth’s. Any liquid water on the surface would very quickly evaporate or freeze. One of the challenges...
Data from the NASA/ESA Solar and Heliospheric Observatory (SOHO) have captured the dynamic movement of the Sun’s atmosphere for over two decades. Now,...
There may have been two windows of habitability for the Moon, according to new research by University of London’s Professor Ian Crawford and Dr. Dirk...
A new study using data from the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument on ESA’s Mars Express spacecraft has...
When one thinks of airborne organisms, spiders do not usually come to mind. However, these wingless creatures have been found 2.5 miles (4 km) up in the...
Astronomers using the SPHERE instrument on ESO’s Very Large Telescope have found an infant gas giant orbiting the young dwarf star PDS 70. Not only have...
NASA’s Mars rover Curiosity has detected organic molecules in 3-billion-year-old sedimentary rocks at the base of the Murray formation at Pahrump Hills,...
