Never-Before-Seen Molecule: Webb Reveals a “Hot Saturn” Exoplanet Atmosphere
New Webb Space Telescope observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet — sulfur dioxide — among other details….

An analysis of more than two decades’ worth of supernova explosions convincingly boosts modern cosmological theories and reinvigorates efforts to answer fundamental questions. A powerful…
A small star was ripped to shreds in October 2018 when it wandered too close to a black hole in a galaxy located 665 million…
A new technique has been developed by astronomers to identify small planets hidden in protoplanetary disks. According to astronomers and astrophysicists, planets are born in…
Astronomers frequently observe carbon monoxide (CO) in planetary nurseries. Because the compound is ultra-bright and extremely common in protoplanetary disks — regions of dust and…
Over 5,000 exoplanets have been detected to date, with more than 90% of them found by using the transit or radial velocity techniques. Of the…
Shining only ~300 million years after the Big Bang, it may be home to the oldest stars in the universe, or a supermassive black hole….
The Solar System has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class as contains Eris, Sedna, Quaoar, Ceres, and…
The U.S. Extremely Large Telescope Program, which includes the Giant Magellan Telescope, was ranked mission critical by the 2020 Decadal Survey on Astronomy and Astrophysics….
Star formation in the Milky Way primarily occurs in long, dense filaments of gas and dust that stretch along the spiral arms. Dubbed “bones” because…
In January 1999, scientists observed mysterious motions within a solar flare. Unlike typical flares that showed bright energy erupting outwards from the Sun, this solar…
The Earth sits in a 1,000-light-year-wide void surrounded by thousands of young stars — but how did those stars form? In a paper appearing today…
Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA’s Chandra X-ray Observatory. This unusual set of features…
Infrared dark clouds (IRDCs) are dark patches of cold dust and gas seen in the sky against the bright diffuse infrared glow of warm dust…
One of the characteristic features of modern cosmology is its description of how galaxies evolve: via a hierarchical process of colliding and merging with other…
Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment. They are common:…
An instrument made by scientists and engineers at the Center for Astrophysics has helped verify that — for the first time in history — a…
The Transiting Exoplanet Survey Satellite, TESS, was launched in 2018 with the goal of discovering small planets around the Sun’s nearest neighbor stars. TESS has…
