How and why do Jupiter-sized exoplanets orbit so close to their stars, also called short-period exoplanets? This is what a recent study presented at the AA | Space

Dual spacecraft capture both hemispheres of interstellar comet 3I/ATLAS at once
The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft and NASA’s Europa Clipper made unique observations of interstellar comet 3I/ATLAS in late 2025. SwRI leads the UVS instruments on both spacecraft, simultaneously imaging both hemispheres of the comet and detecting the comet’s ultraviolet emissions.
Only the third recognized interstellar object, 3I/ATLAS, entered our solar system in July of 2025.
“As the comet passed between Juice and Europa Clipper, we were able to informally coordinate observations between the two spacecraft,” said Dr. Kurt Retherford, the principal investigator of Juice-UVS and Europa-UVS. “Crucially, we observed hydrogen, oxygen and carbon emissions. These elements are produced when gases escaping the comet’s nucleus break apart into atoms when exposed to sunlight.”
NASA’s Psyche Spacecraft Is About To Fly Shockingly Close to Mars
NASA’s Psyche spacecraft is using a daring close flyby of Mars to slingshot toward one of the solar system’s strangest asteroids.

Resilient quantum sensor monitors Earth’s magnetic field from space for 10 months
From navigation to solar weather forecasting, many different areas of research require space-based sensors to measure Earth’s magnetic field as accurately as possible at any given moment. So far, however, existing sensors have consistently struggled with effects including drift, interference from the spacecraft itself, and the harsh conditions of orbit.
Through new research published in Physical Review Applied, Yarne Beerden and colleagues at Hasselt University in Belgium have developed a diamond-based quantum sensor which could offer a promising solution to these problems.
More Star Wars-like worlds emerge as 27 planet candidates with two suns discovered
There’s so little we know about circumbinary planets—planets that orbit two stars instead of one—that they can feel like the stuff of fantasy. And for good reason: to date, we’ve only confirmed the existence of 18 circumbinary planets, compared to the more than 6000 planets we know about in single star systems.
