A new study details the similarities and differences between the spectra of ultra-hot Jupiters, which orbit extremely closely to the host stars, and brown dwarfs scorched by the high-energy radiation of a white dwarf.

Using new machine learning methods to combat the high false-positive rate encountered when searching for objects in crowded stellar fields, researchers have discovered 239 trans-Neptunian objects.

Astronomers have cataloged and characterized 583 X-ray winds from active galactic nuclei: the powerful accreting supermassive black holes at the centers of galaxies.

A new method helps researchers study light echoes: the late-arriving light from an astrophysical object that has been scattered off dust in the object’s vicinity.

The first radial-velocity search of the disk around a directly imaged substellar companion found no satellites, but future instruments will be more than an order of magnitude more sensitive to these objects.

For the first time, researchers have measured from cosmological simulations a parameter relevant to fluctuations in the density of baryonic matter in the early universe.
