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.

This is a near-infrared image from the ground-based VISTA VVV Survey. It shows the Milky Way's galactic bulge, with the location of the Nancy Grace Roman Space Telescope's Galactic Bulge Time Domain Survey superimposed over the regions the Hubble surveyed with its instruments. The Hubble's survey was completed in order to give astronomers a leg up in understanding and interpreting the Roman's results.

NASA’s Roman Space Telescope Is Ahead of Schedule as Hubble Prepares the Ground

NASA’s Roman Space Telescope is reportedly ahead of schedule and under budget, with a September launch target.
Its 15-month Galactic Bulge Time Domain Survey will repeatedly monitor a dense region of the Milky Way for exoplanets and other hard-to-see objects.
Hubble has already surveyed overlapping fields to help astronomers interpret Roman’s future observations.

After Ten Years and 70,000 Targets, a Major UCLA SETI Search Reports No Confirmed Technosignatures

A UCLA team used the Green Bank Telescope for ten years to survey more than 70,000 stars and planetary systems.
The search produced 100 million candidate signals, all of which were traced to human-made interference.
The resulting upper limit suggests fewer than one in 16,000 nearby stars hosts a detectable transmitter of this kind.

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.

A New Solar Telescope at Paranal Is Being Built to Help Exoplanet Hunters Subtract a Star’s Noise

PoET has begun observations at ESO’s Paranal site in Chile.
The telescope studies the Sun to help astronomers model stellar noise in exoplanet data.
Its work supports the search for rocky Earth-like planets around Sun-like stars.

Canada’s proposed POET microsatellite would target Earth-sized worlds around ultracool stars

Canada’s proposed POET mission would focus on Earth-sized planets around small, cool stars.
A 20-centimeter telescope would observe in near-UV, visible and near-infrared bands.
The mission builds on prior Canadian microsatellite programs MOST and NEOSSat.

This artist's illustration shows a young, Sun-like star and an orbiting planet. The young star is emitting powerful x-rays that are eroding the planet's atmosphere. This atmospheric stripping likely dooms planets like this from ever being habitable. Image Credit: NASA/SAO/CXC/M. Weiss

Young Sun-Like Stars May Be Less Destructive to Planet Atmospheres Than Expected

A new study suggests young solar-mass stars may soften and dim in X-rays earlier than expected.
The result could mean less atmospheric stripping for some orbiting planets.
That shift may strengthen the scientific case for targeting Sun-like stars in habitability studies.

Astronomers Watch a Tilted Planetary System Drift Out of View in Real Time

Researchers studied three planets orbiting the F-type star TOI-201 about 371 light-years away.
Transit times and orbital angles appear to be changing in ways observable on human timescales.
The team estimates the planets could stop transiting from Earth’s perspective in about 200 years.

JWST Looked for a Moon Around Two Habitable-Zone Worlds and Ran Into Stellar Noise

JWST improved orbital and radius measurements for TOI-700 d and e.
Researchers estimate a moon signal would be about 20 ppm, but stellar red noise reached roughly 46 ppm.
The non-detection does not rule out moons; it shows the star masked the sought-after signal.

JWST Maps TRAPPIST-1b and 1c as Bare Rocky Worlds With Extreme Day-Night Contrasts

Webb observed TRAPPIST-1b and 1c continuously for 60 hours in infrared light.
Researchers created the first temperature maps of Earth-sized exoplanets around another star.
Both planets show extreme day-night temperature differences, implying little or no atmosphere.
The result helps clarify what kinds of red-dwarf planets may be able to retain atmospheres.

The images of Trumpler 3 and NGC 2353 are open clusters that contains hundreds of young stars that are gravitationally bound together because they formed from the same gas cloud. In this composite image of the clusters, X-rays from Chandra (purple) have been combined with an optical image from the PanSTARRS telescope in Hawaii (red, green, and blue). The stars look like fuzzy dots of different sizes dotting the darkness of space.

NASA Study Suggests Young Sun-Like Stars Calm Down Faster Than Expected

NASA says young Sun-like stars are dimmer in X-rays than previously thought.
The study examined eight clusters aged 45 million to 750 million years.
Lower-than-expected X-ray output could improve prospects for life on orbiting planets.

Stellar Flares Could Broaden the Search for Habitable Worlds Around Small Stars

Exoplanet habitability searches have traditionally emphasized sun-like G-type stars.
The candidate report highlights low-mass K-type and M-type stars.
The reported finding says stellar flares may expand habitable zones around small stars.
