Laboratory experiments provide a way to probe the widely accepted model behind seasonal changes on Mars’s surface, including the formation of “spiders,” “halos,” and “fried eggs.”

The galaxy Corvus A has no known neighbors within 3.3 million light-years and, curiously, exhibits ultraviolet emission indicative of star formation but appears to host no star-forming regions.

Using the largest filled-aperture radio telescope in the world, researchers have carefully analyzed a pulsar’s pulses to assess the gas and dust that lies between us and the pulsar.

Existing observations appear to be in agreement with a model involving a rapidly rotating massive neutron star that launches a jet and an equatorial outflow that remains hidden for several years.

How CUTE — a cubesat has generated a new near-ultraviolet spectrum of the hottest known exoplanet, providing results consistent with those for other ultrahot Jupiters.

Modeling finds that dense crusts on small bodies are resilient against the Rayleigh–Taylor instability, suggesting that such crusts are likely to be common in our solar system.
