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.
Higher Concentration of Metal in Moon’s Craters Provides New Insights to its Origin
Life on Earth would not be possible without the Moon; it keeps our planet's axis of rotation stable, which controls seasons and regulates our climate.
Scientist Find Multiple Planet System Orbiting Gliese 887
The nearest exoplanets to us provide the best opportunities for detailed study, including searching for evidence of life outside the Solar System.
The second-most distant quasar ever discovered now has a Hawaiian name
Astronomers have discovered the second-most distant quasar ever found using three Maunakea Observatories in Hawai'i: W. M. Keck Observatory, the international Gemini Observatory, a Program of NSF's NOIRLab, and the University of Hawai'i-owned United Kingdom Infrared Telescope (UKIRT).
Discovering an exoplanet the size of Neptune
An exoplanet the size of Neptune has been discovered around the young star AU Microscopii, thanks in part to the work of Jonathan Gagné, a former iREx Banting postdoctoral researcher who is now a scientific advisor at the Rio Tinto Alcan Planetarium.
A Blue Spark to Shine on the Origin of the Universe
Why is our Universe made of matter? Why does everything exist as we know it? These questions are linked to one of the most important unsolved problems in particle physics.
Study Suggests Pluto Started Out With Liquid Oceans
A new study suggests that Pluto and other large Kuiper belt objects started out with liquid oceans which have been slowly freezing over time.
Scientists provide new explanation for the far side of the Moon’s strange asymmetry
The Earth‐Moon system's history remains mysterious. Scientists believe the two formed when a Mars‐sized body collided with the proto‐Earth.
Scientists carry out first space-based measurement of neutron lifetime
Scientists have found a way of measuring neutron lifetime from space for the first time - a discovery that could teach us more about the early universe.
