NASA’s Pandora Satellite, CubeSats to Explore Exoplanets, Beyond

Editor’s Note, Jan. 11, 2026: NASA’s Pandora and the NASA-sponsored BlackCAT and SPARCS missions lifted off at 8:44 a.m. EST (5:44 a.m. PST) Sunday, Jan. 11. A new NASA spacecraft called Pandora is awaiting launch ahead of its journey to study the atmospheres of exoplanets, or worlds beyond our solar system, and their stars. Along […]

NASA’s TESS Spacecraft Triples Size of Pleiades Star Cluster

Astronomers have revolutionized our understanding of a collection of stars in the northern sky called the Pleiades. They used data from NASA’s TESS (Transiting Exoplanet Survey Satellite) and other observatories as NASA explores the secrets of the universe for the benefit of all, from the Moon to Mars and beyond.

NASA’s Tally of Planets Outside Our Solar System Reaches 6,000

The milestone highlights the accelerating rate of discoveries, just over three decades since the first exoplanets were found. The official number of exoplanets — planets outside our solar system — tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no […]

NASA Citizen Scientists Find New Eclipsing Binary Stars

When two stars orbit one another in such a way that one blocks the other’s light each time it swings around, that’s an eclipsing binary. A new paper from NASA’s Eclipsing Binary Patrol citizen science project presents more than 10,000 of these rare pairs – 10,001 to be precise. These objects will help future researchers study […]

Discovery Alert: A Rare Glimpse of a Newborn Planet

The Discovery A huge planet with a long name – IRAS 04125+2902 b – is really just a baby: only 3 million years old. And because such infant worlds are usually hidden inside obscuring disks of debris, it is the youngest planet so far discovered using the dominant method of planet detection. Key Facts The […]

The Discovery A planet that could resemble a smaller version of our own Neptune orbits one of two Sun-like stars that also orbit each other. The planet dwells in the “habitable zone,” with a potentially moderate temperature, and poses a challenge to prevailing ideas of planet formation. Key Facts Astronomers once imagined that our solar […]
