Scientists Map Sulfur Residue on Jupiter's Icy Moon Europa

A team has used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a 'gap' in the various wavelengths used to observe this icy water world. The ...

Scientists Identify a Possible Source for Charon's Red Cap

Scientists combined data from NASA's New Horizons mission with novel laboratory experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto's moon Charon and how it ...

How Elliptical Craters Could Shed Light on Age of Saturn's Moons

A new study describes how unique populations of craters on two of Saturn's moons could help indicate the satellites' age and the conditions of their formation. Using data from NASA's Cassini mission, ...

Gaia Space Telescope Rocks the Science of Asteroids

The European Gaia space mission has produced an unprecedented amount of new, improved, and detailed data for almost two billion objects in the Milky Way galaxy and the surrounding cosmos. The Gaia ...

Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Researchers have now developed a single atmospheric model that matches observations of both planets. ...

Why Haven't We Discovered Co-Orbital Exoplanets? Could Tides Offer a Possible Answer?

So far, we haven't discovered any exoplanets with co-orbital objects. A new study suggests tides could be causing oscillations that remove co-orbitals before we can find ...

Physicists Explain How Type of Aurora on Mars Is Formed

Researchers have learned how a type of aurora on Mars is formed. The physicists report discrete aurora form through the interaction of the solar wind and the crust at Mars' southern ...

Mars' Emitted Energy and Seasonal Energy Imbalance

Seasonal imbalance between the solar energy absorbed and released by the planet Mars could be a cause of the Red Planet's dust storms, according to new research. Understanding how the system ...

New Study Indicates Limited Water Circulation Late in the History of Mars

A research team has investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will probably be used when NASA examines samples from the Red Planet in 2030, showed ...

Lunar Soil Has the Potential to Generate Oxygen and Fuel

Soil on the moon contains active compounds that can convert carbon dioxide into oxygen and fuels, scientists report. They are now exploring whether lunar resources can be used to facilitate human ...

Experiments Measure Freezing Point of Extraterrestrial Oceans to Aid Search for Life

A planetary scientist worked with engineers to measure the physical limits for a liquid when salty water is at very high pressure. The results suggest where to look for extraterrestrial life in the ...

Physicists Develop Ideal Testing Conditions of Solar Cells for Space Applications

Researchers have described the optimal conditions for testing perovskite solar cells for ...

Earth's Atmosphere May Be Source of Some Lunar Water

Hydrogen and oxygen ions escaping from Earth's upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new ...

The Instability at the Beginning of the Solar System

Researchers have unveiled a new theory that could help solve a galactic mystery of how our solar system evolved. Specifically, how did the gas giants -- Jupiter, Saturn, Uranus and Neptune -- end up ...

Solar Beats Nuclear at Many Potential Settlement Sites on Mars

While most missions to the moon and other planets rely upon solar power, scientists have assumed that any extended surface mission involving humans would require a more reliable source of energy: ...

Scientists Model Landscape Formation on Titan, Revealing an Earth-Like Alien World

A new hypothesis reveals that a global sedimentary cycle driven by seasons could explain the formation of landscapes on Saturn's moon Titan. The research shows the alien world may be more ...

Two Largest Mars-Quakes to Date Recorded from Planet's Far Side

The seismometer placed on Mars by NASA's InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 Mars-quake. The pair are the first recorded ...

Why Venus Rotates, Slowly, Despite Sun's Powerful Grip

If not for the soupy, fast-moving atmosphere on Venus, Earth's sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the ...

Jupiter's Moon Has Splendid Dunes

Scientists have long wondered how Jupiter's innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like 'Dune.' Now, a research study has provided a new ...

Neptune Is Cooler Than We Thought: Study Reveals Unexpected Changes in Atmospheric Temperatures

New research has revealed how temperatures in Neptune's atmosphere have unexpectedly fluctuated over the past two ...

'Ears' for Rover Perseverance's Exploration of Mars

Scientists have built instruments to give humans eyes and a nose on Mars -- and now they are helping add ears as ...

Scientists Connect the Dots Between Galilean Moon, Auroral Emissions on Jupiter

On November 8, 2020, NASA's Juno spacecraft flew through an intense beam of electrons traveling from Ganymede, Jupiter's largest moon, to its auroral footprint on the gas giant. Scientists ...

'Prenatal' Protoplanet Upends Planet Formation Models

An international research team has discovered a new planet so young that it has yet to emerge from the womb of matter where it is forming. This is the youngest protoplanet discovered to date. ...
