Space Radiation Can Produce Some Organic Molecules Detected on Icy Moons
As missions prepare to visit ocean worlds like Enceladus and Europa, new findings show scientists must first learn to distinguish between radiation-made organics and those born in a subsurface sea.
Zircon Crystals Could Reveal Earth’s Path Among the Stars
Researchers found signs of melting in zircon crystals in the crust that correspond to our planet’s journey through the galaxy’s spiral arms.
Magnetic “Switchback” Detected near Earth for First Time
Until recently, this type of zigzag shape—formed by energetic rearrangement of magnetic field lines—had been seen only near the Sun.
Planets Might Form When Dust “Wobbles” in Just the Right Way
A liquid metal experiment has shown how magnetic rotational instability might allow dust to pool together in disks around young stars to form new worlds.
Scientists May Have Finally Detected a Solid Inner Core on Mars
Seismic clues from NASA’s InSight mission suggest that Mars hides a solid inner core, and raise new questions about why the planet’s magnetic field disappeared.
Small Satellites, Big Futures
Programs that teach students to design, build, and launch tiny satellites are helping to inspire the next generation of space scientists and engineers.
Squaring Up in Space
CubeSats emerge as the little spacecraft that could.
New Evidence for a Wobbly Venus?
The orientation of wind-blown impact deposits on Venus is not consistent with modeled wind directions, suggesting Venus’s rotation axis may have changed.
微生物能在地球大气中繁衍生息吗？还是仅能勉强存活？
一种自下而上的建模方法让科学家得以更深入地了解大气中的微生物群落。
Trio of Space Weather Satellites Take Flight
