NASA Science Faces an “Extinction-Level Event” with Trump Draft Budget Proposal
The initial draft of President Donald Trump’s budget request proposes devastating cuts to NASA’s science research, future space missions, and field centers.
A Super Speedy Star May Be Streaking Through Our Galaxy
Astronomers suggest the star is towing along an exoplanet. The system could be traveling fast enough to escape the Milky Way.
Magnetic Meteorites May Explain How the Solar System Assembled
Faint magnetic properties in primitive asteroid fragments suggest an early magnetic field strong enough to shepherd the growth of the outer planets.
Planetary Perturbations May Strengthen Gaia
Large-scale disruptions to life may ultimately increase ecological complexity over geologic timescales, though the risk of extinction always looms.
Small Stars Produce Mighty UV Flares
Stronger-than-expected ultraviolet flares could either provide exoplanets the sparks of life or prevent them from having life at all.
All Eyes on Jupiter
Astronomers hope amateur enthusiasts will help them monitor Jovian weather.
Anemic Stars Don’t Host Super-Earths
Planetary systems need the right stuff to make planets, and some stars just don’t have it.
Britney Schmidt: Following the Ice
An Earth and planetary scientist is most at home in cold places that mimic the worlds of the outer solar system.
