Calculations show that routine tidal disruption of stars by the supermassive black hole at the galactic center can provide enough cumulative energy to form and maintain large-scale structures like the Fermi Bubbles.

35 dippers — young stellar objects that exhibit episodic dimming — are found within one year’s worth of Transiting Exoplanet Survey Satellite (TESS) full-frame images using a convolutional neural network.

New ALMA observations of a nearly edge-on disk reveal an interesting case where both a star (from the environment and the disk) and a planet (from the disk) are growing in tandem.

New modeling suggests that volcanoes are unlikely to produce methane fluxes comparable to biological fluxes, indicating that atmospheric methane with carbon dioxide can be used as a biosignature.

New observations of CQ 4479, a cold quasar at z ~ 0.405, reveal a starburst galaxy with a young stellar population, a high gas mass fraction, and an early-stage AGN that doesn’t yet dominate the far-infrared emission.

New analysis suggests that 90% of near-Earth asteroids and 93% of potentially hazardous asteroids are detectable within the next 50 years using an an I52-class or Subaru-class telescope.
