Several Oceans’ Worth of Ancient Water May Reside in Minerals Buried Below Mars’ Surface
Much of Mars’ ancient water was buried in the planet’s crust, not lost to space. Several oceans’ worth of ancient water may reside in minerals…

Researchers simulate conditions necessary for planet’s unique magnetic field. New Johns Hopkins University simulations offer an intriguing look into Saturn’s interior, suggesting that a thick…
The signatures of ancient magnetic fields in meteorites support an extended time frame for the cooling of molten protoplanetary cores. If you stumble upon an…
15 years of radar measurements provide new information on planet’s spin, internal structure. Venus is an enigma. It’s the planet next door and yet reveals…
During a brief swing by Venus, NASA’s Parker Solar Probe detected a natural radio signal that revealed the spacecraft had flown through the planet’s upper…
Imagine trying to pick up a pebble or scrape microbes off a cave wall in a bulky spacesuit with puffy gloves on, under a time…
NASA’s Parker Solar Probe mission has given scientists the first complete look at Venus’ orbital dust ring, a collection of microscopic dust particles that circulates…
New research suggests that rocks in the Martian crust could produce the same kind of chemical energy that supports microbial life deep beneath Earth’s surface….
As the solar system was developing, the giant planets (Jupiter and Saturn) formed very early, and as they grew, they migrated both closer to and…
Mars had dry and wet eras and dried up for good 3 billion years ago. While attention has been focused on the Perseverance rover that…
Hebrew University Researcher Introduces New Approach to Three-Body Problem, Predicts its Outcome Statistics. The “three-body problem,” the term coined for predicting the motion of three…
A proposed mission called Io Volcano Observer (IVO) would visit Jupiter’s moon Io, which is a true volcanic wonderland with hundreds of erupting volcanoes gushing…
Oxygen in the atmosphere may not be an entirely reliable ‘biosignature,’ but there are ways to distinguish false positives from signs of life, scientists say….
Auroral displays continue to intrigue scientists, whether the bright lights shine over Earth or over another planet. The lights hold clues to the makeup of…
To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do to rule out non-biological chemical…
Both Earth and Mars currently have oxidizing atmospheres, which is why iron-rich materials in daily life develop rust (a common name for iron oxide) during…
Astronomers at Western University have discovered the most rapidly rotating brown dwarfs known. They found three brown dwarfs that each complete a full rotation roughly…
