New observations of mud cracks made by NASA’s Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments,...
To track the Red Planet’s spin rate, planetary scientists relied on the Rotation and Interior Structure Experiment (RISE) onboard NASA’s InSight lander....
New research shows that long-lived volcanism, driven by early, energetic collisions on Venus, offers an explanation of its young surface age with stagnant-lid...
New research from the University of Toronto shows that from approximately 2 billion until 600 million years ago, an atmospheric tide driven by the Sun...
The Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument onboard NASA’s Perseverance rover has...
Some steep slopes on Mars have gullies with morphologies suggesting that they were formed by a liquid. However, the planet’s current climate is not conducive...
This new image of Saturn, taken with the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope on June 25, 2023, serves as...
Planetary scientists using the Imaging Ultraviolet Spectrograph (IUVS) instrument onboard NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft...
Earth’s rotational pole has drifted toward 64.16°E at a speed of 4.36 cm per year during 1993-2010 due to groundwater depletion and resulting sea level...
Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of onset is unknown, with ages ranging from the Hadean to...
Astronomers using the Karl G. Jansky Very Large Array in New Mexico have observed a bright, compact spot centered at Uranus’ north pole at several wavelengths....
On May 24, 2023, as part of the A Sign in Space project, ESA’s ExoMars Trace Gas Orbiter (TGO) will transmit an encoded message to Earth to simulate...
Saturn’s ring system may well have formed when dinosaurs were still walking on the Earth, and will last only another few hundred million years at most,...
Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
Ascraeus Mons is the northernmost and tallest of three prominent volcanoes found in the Tharsis region of Mars, a volcanic plateau in the planet’s western...
Low frequency sounds can travel vast distances across our planet, carrying information about the events that generated them as well as the medium through...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
Arguably the most enigmatic of the Maya calendar cycles, the 819-day count has challenged modern scholars for decades. Even today it is not completely...
