A new catalog provides a wealth of data from 140 fast radio bursts, updating or providing for the first time the polarization, raw voltage, and localization information for these bursts.
The discovery of a Milky Way star with iron abundance three orders of magnitude lower than our Sun’s iron abundance may prompt a reevaluation of how metal-poor globular cluster stars can be.
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.
