Exploring both ends of the pulsar spectrum, researchers have discovered a millisecond pulsar and two long-period pulsars, including the slowest-spinning pulsar discovered so far.

Nearly all — 99.6% — of the 72,964 unobscured quasar candidates in a new catalog of the southern sky have never been previously identified as such via spectroscopy.

Using JWST transit observations, researchers have determined that a low-density “super-puff” exoplanet is rotating slower than expected based on certain theories of these planets’ origins.

Scattering of photons in Earth’s atmosphere makes it challenging to assess balloon-borne gamma-ray observations, and modeling shows that scattering is especially impactful for lower energies.

Laboratory studies suggest that crystals of halite — the mineral form of sodium chloride and an unrefined version of table salt — may be the best way to preserve and transport potential Martian microbial life.

Inferred yields of oxygen and iron from core-collapse supernovae agree with expectations for a model in which many stars that are lighter than 40 solar masses implode rather than explode.
