exoplanets

NASA's upcoming Nancy Grace Roman Space Telescope will feature the first space-based active coronagraph with deformable mirrors, enabling direct imaging of exoplanets similar to Jupiter and potentially paving the way for detecting Earth-like worlds.

A new study presents the TESS All-Sky Rotation Survey (TARS), the largest catalog of stellar rotation periods to date, covering over one million stars within about 1,600 light-years of the Sun, using data from the TESS satellite.

The Euclid space telescope captured the largest and most detailed visible-light image of the Milky Way's galactic bulge, showing over 60 million stars and aiding exoplanet discovery via gravitational microlensing.

ThousandWorlds is a benchmark dataset for machine-learning emulation of exoplanet climates, containing approximately 1800 simulations from five global climate models. Gaussian process methods outperform deep learning baselines in this low-data, multi-simulator regression task.

NASA announces that the Nancy Grace Roman Space Telescope will launch soon to investigate potential life in the Milky Way, and invites the public to send their names on the mission.

Scientists used a machine learning algorithm to analyze TESS data, identifying over 10,000 new exoplanet candidates, potentially tripling the known count. One candidate was confirmed as a hot Jupiter, validating the method.
