that of Jupiter, classifying it as a “super‑Jupiter.” Initial hints of the planet emerged from NASA’s Transiting Exoplanet Survey Satellite (TESS), and an international team led by researchers at Queen’s University Belfast spent several years gathering...

A newly introduced open source Python toolkit named exoVetter aims to standardize how astronomers validate exoplanet transit signals across massive datasets. The search for distant worlds beyond our solar system has entered a high-volume era, driven by...

Scientists used a novel technique on NASA data to uncover a previously hidden planet, revealing a world once thought out of reach. NASA’s TESS (Transiting Exoplanet Survey Satellite) has identified a distant exoplanet hidden in its archive by...

planetary companions, unveiling a potential gas giant in the process. By analyzing data from NASA’s Transiting Exoplanet Survey Satellite (TESS), researchers investigated the behavior of Delta Scuti stars, which oscillate with a regularity that acts as...

an elongated orbit before tidal interactions eventually force it to stabilize. Data gathered by NASA’s Transiting Exoplanet Survey Satellite (TESS) between 2019 and 2024 allowed researchers to map the shifting geometry of the planet’s transit. Their...

The planet, which measures about 2.55 times the radius of Earth, was initially detected by NASA’s Transiting Exoplanet Survey Satellite (TESS). By monitoring the subtle periodic dimming of a host star, researchers identified the candidate before...

WASP-17b, WASP-19b, HAT-P-1b and HD 209458b. (CREDIT: UCLA) The Physics of a Disappearing World NASA’s Transiting Exoplanet Survey Satellite (TESS) identified the system by monitoring periodic drops in light as the planet crossed the face of its star....

4​σ. (CREDIT: Max Kroft et al, arXiv) Detecting an Anomaly The candidate was first spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS), which monitors stars for the subtle brightness dips caused by passing planets. To confirm the planet’s...

The team, publishing their results in The Astrophysical Journal Letters, merged measurements from NASA’s Transiting Exoplanet Survey Satellite (TESS), the high‑precision NEID spectrograph, and additional facilities capable of tracking minute shifts in...

Astronomers have discovered a rare exoplanet orbiting in the opposite direction of its host star, challenging everything we know about planetary formation. Astronomers have uncovered a celestial oddity that defies the standard models of planetary...

between planets and stars are born. The companion, designated HIP 61637 b, was first flagged by NASA’s Transiting Exoplanet Survey Satellite (TESS) and later examined in a study posted on arXiv. Its well‑determined mass, orbital characteristics, stellar...

unexpected.” The Case for a Reborn World The team’s evidence is further bolstered by data from NASA’s Transiting Exoplanet Survey Satellite (TESS). Observations revealed a subtle, periodic brightness oscillation every 4.399 days. This cycle, which has...

an Orbital Irregularity The unusual nature of the planet first emerged through data from NASA’s Transiting Exoplanet Survey Satellite (TESS). By monitoring dips in stellar brightness, scientists identified the planet’s rapid two-day orbital period....
