Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere...
Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have...
Primordial black holes have been theorized for decades and could even be ever-elusive dark matter. Still, no primordial black hole has ever been observed....
These Earth-size ovals at Jupiter’s north and south poles are visible only at ultraviolet (UV) wavelengths, and appear and disappear seemingly at random,...
Scientists from Curtin University and the University of Adelaide have analyzed a 4.45-billion-year-old zircon grain from a famous Martian meteorite called...
Several of the icy moons in the Jupiter and Saturn systems appear to possess internal liquid water oceans. Our knowledge of the Uranian moons is more limited...
456P/PANSTARRS, an active, main-belt asteroid first spotted in 2021, is recurrently active, and activity is likely driven by the sublimation of volatile...
An asteroid struck Mars 11 million years ago and sent pieces of the planet hurtling through space; one of these chunks eventually crashed into the Earth....
When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first close glimpse of this ice-giant planet. Alongside the discovery...
A team of scientists from the Lunar and Planetary Laboratory at the University of Arizona, TU Delft, and Caltech has developed a new method to compute...
Sedimentary mineral deposits found on the surface of Mars may have been left by an ancient sea 3.5 billion years ago. New results from China’s Tianwen-1/Zhurong...
On Earth, solar radiation can transmit down to multiple meters within ice, depending on its optical properties. Organisms within ice can harness energy...
A bright comet from the Oort cloud named C/2023 A3 (Tsuchinshan-ATLAS) is passing by Earth and will be visible through the second half of October 2024.
This...
Europa Clipper lifted off from NASA’s Kennedy Space Center in Florida at 12:06 p.m. EDT on October 14, 2024 to begin a six-year journey to Jupiter’s...
Astronomers using the NASA/ESA Hubble Space Telescope observed Jupiter’s most distinctive feature, the Great Red Spot, with on eight dates over a single,...
In a new study, astronomers compared high-resolution images of Uranus from the NASA/ESA Hubble Space Telescope to the more-distant view from NASA’s New...
