NASA's New Catalog Reveals 126 Newly Discovered Planets

n a groundbreaking revelation, NASA has unveiled a comprehensive catalog showcasing 126 recently discovered planets orbiting distant stars. This catalog, a collaborative effort by a global team of scientists in partnership with the Keck Observatory in Hawaii, sheds light on the diverse array of exoplanets beyond our solar system, ranging from enigmatic worlds in extreme conditions to potentially habitable planets.

Utilizing data from NASA's Transiting Exoplanet Survey Satellite (TESS), researchers meticulously examined these celestial bodies, delving into their characteristics and behaviors. The findings, now published in The Astrophysical Journal Supplement, mark a significant leap forward in our understanding of exoplanetary systems.

Over a span of three years, the team meticulously curated the catalog, analyzing a staggering 13,000 radial velocity (RV) measurements to determine the masses of 120 confirmed planets and 6 potential candidates situated in the northern hemisphere of Earth.

While these distant planets remain invisible to the naked eye, their presence is discernible through the subtle gravitational tug they exert on their host stars. This gravitational interplay induces a detectable "wobble" in the stars, causing their light to subtly shift in color as they move closer or farther away from Earth-bound telescopes.

By scrutinizing these radial velocity variations, astronomers can glean crucial insights into the composition and dynamics of these distant exoplanetary systems. The rhythmic dance of the host star, influenced by its unseen companions, enables scientists to infer the existence of exoplanets and accurately gauge their masses, unraveling the mysteries of these distant worlds.
