A New Look at Mars’ Eerie, Ultraviolet Nighttime Glow

Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of the planet's sky: a soft glow created by chemical reactions occurring tens of miles above the surface.

Global Magnetic Field of the Solar Corona Measured for the First Time

An international team of solar physicists, including academics from Northumbria University, in Newcastle upon Tyne, has recently measured the global magnetic field of the outer most layer of the Sun’s atmosphere, the solar corona, for the first time.

NASA Data Helps Uncover Our Solar System’s Shape

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions.

Ammonia Sparks Unexpected, Exotic Lightning on Jupiter

NASA's Juno spacecraft - orbiting and closely observing the planet Jupiter - has unexpectedly discovered lightning in the planet's upper atmosphere, according to a multi-institutional study led by the NASA/Jet Propulsion Laboratory (JPL), which includes two Cornell University researchers.

Lava Tubes on Mars and Moon Wide Enough to Host Planetary Bases

The international journal Earth-Science Reviews published a paper offering an overview of the lava tubes (pyroducts) on Earth, eventually providing an estimate of the (greater) size of their lunar and Martian counterparts.

Early Mars Was Covered in Ice Sheets, Not Flowing Rivers

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously though.

Researchers Explain the Origins of Stony-Iron Meteorites

Pallasites are stony-iron meteorites, and are known for their unusual, visually attractive structures. However, to date, their origins have been hotly disputed.

Scientists Contribute to Study Exploring Magnetization Preserved for Billions of Years in Meteorite Samples

X-ray experiments at Lawrence Berkeley National Laboratory (Berkeley Lab) played a key role in resolving the origin of rare, odd meteorites that have puzzled scientists since their discovery a half-century ago.

Asteroid Shower on the Earth-Moon System 800 Million Years Ago Revealed by Lunar Craters

A research team led by Osaka University investigated the formation ages of 59 lunar craters with a diameter of approximately 20 km using the Terrain Camera (TC) onboard the lunar orbiter spacecraft Kaguya.

The Venus ‘Ring of Fire’

Years ago, planetary researchers discovered unusual circular structures on the surface of Venus when observing high-resolution images from NASA's Magellan mission.

The Lion’s Roar: New Telescope Spots Superflare in Leo

A new telescope in Okayama, Japan observed a superflare on a star in the constellation Leo to better understand how superflares on the Sun can affect technology and life on Earth.

Dying Stars Breathe Life into Earth

As dying stars take their final few breaths of life, they gently sprinkle their ashes into the cosmos through the magnificent planetary nebulae.
