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？

New subsurface imaging and rock samples suggest that Silverpit Crater formed from an impact that occurred roughly 45 million years ago.
This Star Stripped Off Its Layers Long Before Exploding
A star 2 billion light-years away apparently shed most of its outer layers before exploding, providing new insights into stellar structure—and new mysteries for astronomers to solve.
Hayabusa2’s Final Target is 3 Times Smaller Than We Thought
It also spins twice as fast as previous estimates suggested. A spacecraft touchdown will be challenging, but not impossible.
Are There Metal Volcanoes on Asteroids?
Upcoming NASA observations may reveal whether ferrovolcanism shaped 16 Psyche’s metallic surface and hidden interior.
Tilted Planet System? Maybe It Was Born That Way
New observations could shed light on the degree to which misalignment in a planet-forming disk contributes to skewed planetary orbits.
