Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our system. This discovery paves the way for future atmospheric studies to better understand these types of planets.

SAN ANTONIO — March 13, 2025 —Just hours after touching down on the surface of the Moon on March 2 aboard Firefly Aerospace’s Blue Ghost 1 lander, the Southwest Research Institute-led Lunar Magnetotelluric Sounder (LMS) was activated and deployed its five sensors to study the Moon’s interior by measuring electric and magnetic fields. The LMS instrument is the first extraterrestrial application of magnetotellurics.

WASHINGTON, D.C. — The U.S. Naval Research Laboratory (NRL), in partnership with NASA’s Marshall Space Flight Center (MSFC), has developed StarBurst, a small satellite (SmallSat) instrument for NASA's StarBurst Multimessenger Pioneer mission, which will detect the emission of short gamma-ray bursts (GRBs), a key electromagnetic (EM) signature that will contribute to the understanding of neutron star (NS) mergers.

Astronomers from the Max Planck Institute for Astronomy have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million spectra from ESA’s Gaia mission, results from the LAMOST spectral survey, and machine learning. Dust makes distant astronomical objects appear more reddish and dimmer than they really are, so the new map will be an important tool for astronomers to make sense of their observations.  The study has also revealed unusual properties of cosmic dust that will lead to further research.
