TESS Survey Uncovers 27 New Circumbinary Planet Candidates

Researchers examined 1,590 eclipsing binary stars in TESS data.
The team used apsidal precession to identify 27 new circumbinary planet candidates.
Further confirmation will likely require follow-up methods such as radial velocity measurements.

Researchers Identify 27 New Candidate Worlds Orbiting Two Stars

A UNSW team says it found 27 candidate circumbinary planets using NASA TESS data.
The search relies on apsidal precession, tracking changes in eclipsing binary stars rather than only direct transits.
The result suggests planets orbiting two stars may be more common than current catalogs indicate.

NASA’s Planet-Hunting TESS Reveals Dazzling Night Sky

NASA’s TESS Publishes Its Most Complete Night-Sky Mosaic Yet

NASA’s new TESS mosaic combines 96 sky sectors observed from 2018 to 2025.
The image marks 679 confirmed exoplanets and 5,165 candidates identified by the mission.
The release underscores how TESS has turned exoplanet hunting into a large-scale sky survey.

Astronomers Report More Than 11,000 Exoplanet Candidates in a Single Machine-Learning Sweep

A preprint reports 11,554 exoplanet candidates found in TESS data.
The search analyzed light curves from 83,717,159 stars using machine learning.
The candidates are not yet confirmed and the study has not been peer reviewed.

This artist's illustration shows the gas giant TOI-5205 b orbiting its M-dwarf (red dwarf) star. Astronomers expect to find massive gas giants around more massive stars than this, so this arrangement is a puzzle. It's not the only gas giant around a low-mass star, and collectively, they challenge astronomers' understanding of planet formation. Image Credit: Katherine Cain, Carnegie Science.

A Giant Planet Around a Tiny Star Is Testing Theories of How Worlds Form

TOI-5205b is a roughly Jupiter-mass planet orbiting a low-mass M-dwarf every 1.6 days.
Its size and host-star mass strain standard disk-scaling expectations in planet formation theory.
Researchers are now studying similar systems with JWST through the GEMS program.

This artist's illustration shows an Ultra-Short Period planet orbiting its star. This type of exoplanet takes less than one Earth day to orbit its star. Some scientists think these exoplanets are the remaining rocky cores of once much larger gas giants whose atmospheres have been stripped away by their stars. Image Credit: NASA, ESA, and A.

AI sifts TESS observations and helps validate more than 100 new exoplanets

Researchers used the RAVEN machine-learning pipeline on TESS data covering more than 2 million stars.
The study reports over 100 newly validated exoplanets and more than 2,000 vetted candidates.
The work highlights how AI can help manage false positives and extract more science from large survey archives.
