Simulations predict that the Roman Space Telescope will discover 33 ± 9 young exoplanets in a one-month survey, expanding our understanding of the properties of planets around very young stars.

Though Type Ic supernovae are classified in part by the lack of helium lines in their spectra, recent modeling of a near-infrared supernova spectrum suggests that helium is present but undetectable in the optical.

Researchers present the first high-resolution multi-wavelength observations of a triple-nucleus merger, showing one black hole with mass of order 100 million solar masses and two with evidence of tidal disruption.

Using the SHAllow RADar split-chirp technique, researchers showed how orbital radar loss estimates could be used to map the composition of Mars’s volcanics on a global scale.

Analysis of JWST and Hubble Space Telescope observations of the galaxy “Eridu” suggests that the galaxy formed within 300 million years of the Big Bang and was quenched by a redshift of z ~ 10.

The combination of data and binary neutron star merger simulations shows that the source of GRB 230307A is unlikely to be a globular cluster; a disk origin is possible but requires finely tuned conditions.
