Measuring the distribution of energy at infrared wavelengths in nearby galaxy M31 demonstrates how supernovae heat their local environments and allows for estimation of how much dust is destroyed in the blast.
During its five-year cruise to the Jupiter system, the Juno spacecraft observed 80 coronal mass ejections, allowing astronomers to assess how these explosions’ magnetic fields evolve as they travel.
The position, shape, and metallicity of a newly discovered, 2,000-light-year-long star-forming region indicate that the structure is most likely a tidal dwarf galaxy beginning to form.
The first neural network designed to classify supernovae based on their light curves is able to identify the supernova type with 75% accuracy on the night of the initial alert and with 89% accuracy 50 days later.
Applying the new technique of data-driven retrieval to previously collected spectra, astronomers determine the most likely parameters for the atmosphere of a brown dwarf: cloud-free and poor in metals like iron.
An analysis of craters on the second largest moon of Saturn suggests that the moon is not fully differentiated and its craters were likely altered by heating events after the impacts that created them.
