Abundant but Ambiguous: Understanding the Atmospheres of Sub-Neptunes with JWST
Sub-Neptunes may be the most abundant planet type in the galaxy, but they are not yet well understood. A recent study uses JWST to characterize the atmosphere of the sub-Neptune GJ 3090b to aid in the study of these planets.
Introducing exoALMA: a survey of 15 large, bright protoplanetary disks that has revealed gas structures that point to potential planet formation.
Astrobites reports on a curious cluster of stars moving together near Sgr A*. Is it a stellar coincidence, or a sign of a hidden black hole?
Some neutron stars might arise from the collapse of a white dwarf. Simulations show that this transformation is likely accompanied by a burst of element creation.
Could tidal disruption events, which happen when a star gets too close to a black hole, explain the unusual properties of little red dot galaxies?
Astrobites reports on potential formation mechanisms for hot Neptunes, the rarest type of sub-Neptune exoplanets.
The 1,000-foot-wide Arecibo Telescope discovered nearly 60 binary or triple asteroid systems. 2020 BX12 was the final binary asteroid discovered with Arecibo before the telescope collapsed in 2020.
How do globular clusters, some of the universe’s oldest objects, originate? Recent simulations of early universe star formation provide potential pathways for their formation and how JWST might be able to spot their high-redshift progenitors.
New JWST observations provide a richly detailed look at the jets from young stars still shrouded in dusty disks.
