A Solar System–Sized Experiment: New Proposal for Precision Cosmology and More
To measure vast distances with tiny uncertainties, astronomers need to think outside the box. A new study proposes an ambitious mission that could revolutionize our understanding of cosmology, dark matter, and more.
JWST has revealed an intriguing new group of galaxies with flat, extended, red disks that might be the precursors to today’s massive galaxies.
Astrobites reports on an extra protoplanet that might be lurking in the dust around a nearby star.
In 2020, astronomers spotted curious color changes and other new behavior from the first known blazar.
Can a model in which the solar system forms in a dense, filamentary gas cloud explain the radioactive atoms found in meteorites?
A survey of 45 nearby galaxies may help researchers interpret ultraviolet emission from galaxies in the early universe.
Serendipitous Supernovae
In an era of industrial-scale surveys of the night sky, sometimes unrelated projects happen to spot the same short-lived event with different tools. A new article published in The Astrophysical Journal describes a recent handful of these happy overlaps.
Upcoming missions to Venus will seek trace amounts of sulfur-containing molecules that can help us study the planet’s sulfuric acid clouds and search for active volcanoes.
Giving Stars a Brake
Astrobites reports on how stellar rotation is slowed by stellar winds via magnetic braking, with a special focus on stars cooler than the Sun.
