Discovery Alert: ‘Baby’ Planet Photographed in a Ring around a Star for the First Time! 

The (Proto) Planet:  WISPIT 2b  The Discovery:  Researchers have discovered a young protoplanet called WISPIT 2b embedded in a ring-shaped gap in a disk encircling a young star. While theorists have thought that planets likely exist in these gaps (and possibly even create them), this is the first time that it has actually been observed. […]

NASA’s Webb Telescope Studies Moon-Forming Disk Around Massive Planet

NASA’s James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disk encircling a large exoplanet. The carbon-rich disk surrounding the world called CT Cha b, which is located 625 light-years away from Earth, is a possible construction yard for moons, although no moons are […]

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 Study: Celestial ‘Accident’ Sheds Light on Jupiter, Saturn Riddle

An unusual cosmic object is helping scientists better understand the chemistry hidden deep in Jupiter and Saturn’s atmospheres — and potentially those of exoplanets. Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, Saturn, and gas planets like them orbiting other stars? A new […]

Astronomers Map Stellar ‘Polka Dots’ Using NASA’s TESS, Kepler

Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess — […]

Webb Narrows Atmospheric Possibilities for Earth-sized Exoplanet TRAPPIST-1 d

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from NASA’s James Webb Space Telescope, […]

NASA Installs Key ‘Sunblock’ Shield on Roman Space Telescope

Technicians have successfully installed two sunshields onto NASA’s Nancy Grace Roman Space Telescope’s inner segment. Along with the observatory’s Solar Array Sun Shield and Deployable Aperture Cover, the panels (together called the Lower Instrument Sun Shade), will play a critical role in keeping Roman’s instruments cool and stable as the mission explores the infrared universe. […]

NASA’s Chandra Finds Baby Exoplanet is Shrinking

A star is unleashing a barrage of X-rays that is causing a closely-orbiting, young planet to wither away an astonishing rate, according to a new study using data from NASA’s Chandra X-ray Observatory and described in our latest press release. A team of researchers has determined that this planet will go from the size of Jupiter down to a small, barren world. […]
