Age dependence of the occurrence and architecture of ultra-short-period planet systems - Nature Astronomy
Observational evidence shows that the occurrence of ultra-short-period planets increases with age and their system architecture evolves on billion-year timescales, providing new constraints on the for...

Evidence for a Catastrophically Disrupted Open Cluster
Of the many discoveries uncovered by the Gaia astrometric mission, some of the most exciting are related to nearby dispersed stellar structures. We analyze one such structure in the Milky Way disk, OC...

Is There a Black Hole Hiding in the Inner Solar System?
Mercury’s perplexing orbit led to the prediction of a new inner planet, Vulcan. Einstein’s general relativity removed the need for such a body, but today’s paper pursues a wild idea - does Vulcan exis...

This afternoon's view of the sun in H-Alpha. Prefer to invert these images as it tends to bring out more detail for me. A huge prominence and lots of other surface detail #astronomy #astrophotography #photography #sun #solar #h-alpha #space #deepspace #astro

Near-circular orbits for planets with Earth-like sizes and instellations around M and K dwarf stars - Nature Astronomy
Measurements of the orbital eccentricities of exoplanets with similar sizes and irradiation as Earth show that these worlds further resemble Earth with near-circular orbits, removing a potential barrier to life.

A nearby dark molecular cloud in the Local Bubble revealed via H2 fluorescence - Nature Astronomy
Eos is a newly discovered molecular cloud sitting just 94 pc from the Sun. It was detected through the far-UV emission of its molecular hydrogen, having been missed in conventional molecular gas surveys due to a low abundance of common gas tracers.
