NASA Webb Finds Young Sun-Like Star Forging, Spewing Common Crystals
Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper Belt and Oort Cloud. Now, looking outside our solar system, NASA’s James Webb Space Telescope has returned the first conclusive evidence that links how those conditions are…

NASA Helps Connect Astronomers and Community Colleges Across the Nation
The NASA Community College Network (NCCN) and the American Astronomical Society (AAS) have teamed up to provide an exciting and impactful program that brings top astronomy researchers into the classrooms of community colleges around the United States. The Harlow Shapley Visiting Lectureship Program, named for astronomer Harlow Shapley (1885-1972), has a history dating back to the 1950s, when it provided…

Astronomers Catch Unprecedented Features at Brink of Active Black Hole
International teams of astronomers monitoring a supermassive black hole in the heart of a distant galaxy have detected features never seen before using data from NASA missions and other facilities. The features include the launch of a plasma jet moving at nearly one-third the speed of light and unusual, rapid X-ray fluctuations likely arising from near the very edge of…

Astronomers Find Early Fast-Feeding Black Hole Using NASA Telescopes
A rapidly feeding black hole at the center of a dwarf galaxy in the early universe, shown in this artist’s concept, may hold important clues to the evolution of supermassive black holes in general. Using data from NASA’s James Webb Space Telescope and Chandra X-ray Observatory, a team of astronomers discovered this low-mass supermassive black hole just 1.5 billion years after the…

420 Years Ago: Astronomer Johannes Kepler Observes a Supernova
In October 1604, a new star appeared in the sky, puzzling astronomers of the day. First observed on Oct. 9, German astronomer Johannes Kepler (1571-1630) began his observations on Oct. 17 and tracked the new star for over a year. During that time, it brightened to magnitude -2.5, outshining Jupiter, and for several weeks remained visible in the daytime. Publication…

NASA Astronomer Sees Power in Community, Works to Build More
Science is often portrayed as a solitary affair, where discoveries are made by lone geniuses toiling in isolation. But Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says solving problems with the people around her is one of the best parts of her job. “Oh, man, working with people is all I do!” said…
