Cataloging asteroids is tricky because they are faint and they don't stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived Hubble images to snag a largely unseen population of smaller asteroids in their tracks. (1/6)
#WomenAstronomersDay: Celebrate the lives of space pioneers Nancy Grace Roman and Vera Rubin! Dr. Roman was NASA’s first Chief of Astronomy. Dr. Rubin found evidence for dark matter. Both worked tirelessly for the advancement of women in science. Credit: STScI.
Happy first anniversary, #NASAWebb! One year after beginning science operations, Webb is celebrating with a highly detailed image of the closest star-forming region to Earth. Peer deeper in the cloud: https://webbtelescope.pub/3JUoBTA
The *original* ringed planet reigns supreme with #NASAWebb.
#Saturn appears dark in this image because methane gas absorbs almost all the sunlight falling on the atmosphere at this infrared wavelength. But its iconic rings are brilliantly bright: https://webbtelescope.pub/44nXE2p
#Orion is one of the most recognizable constellations in the night sky. But the two-dimensional representation gives the impression that the stars are all at the same distance.
This scientific visualization addresses both of these issues by viewing the Orion constellation from a three-dimensional perspective. The true space distribution of the constellation as well as how stellar brightness changes with viewing position are revealed by circling around the stars.
The first #NASAWebb results from TRAPPIST-1 are in! Measurements of mid-infrared light from TRAPPIST-1 b indicate that the rocky Earth-sized planet is hot enough to bake pizza and is probably devoid of atmosphere. What does this mean? ➡️ https://webbtelescope.pub/3nlCcLc #space#astronomy#JWST#Trappist1b
#NASAWebb confirmed its first exoplanet! Classified as LHS 475 b, the planet is rocky and almost precisely the same size as Earth. It’s only 41 light-years away and whips around its star in just two days. Does it have an atmosphere? #AAS241#JWSThttps://webbtelescope.pub/3QsE6V6
The moment we’ll never forget: watching #NASAWebb head off into the universe, successfully performing its very first operation—the deployment of the solar array that powers the rest of its mission. 🤩 Credit: NASA/ESA/CSA. #WebbLaunchAnniversary#STScI#JWST
