The Space Telescope Science Institute is the Science Operations Center for Webb, Hubble, and the upcoming Roman space telescopes, & Mission Operations Center for Webb. We help humanity explore the universe with advanced space telescopes and data archive.
Flying through Dulles Airport near D.C.? If you’re taking the Metro, expect to be awed by almost 40 recently installed images from #NASAWebb, paired with more than 30 from the ever-active Hubble, on your way to the main terminal: https://bit.ly/4qPfl7m #wmata 🔭 🧪

In 2023, #NASAWebb observed a spectacular light show on Jupiter, the largest planet in our solar system. The planet’s auroras are hundreds of times brighter and more energetic than Earth’s. Credit: NASA, ESA, CSA, J. Nichols (University of Leicester), M. Zamani (ESA/Webb). 🔭 🧪

#NASAWebb 🤝 Rocky exoplanets
With Webb, astronomers have found that several rocky worlds around red dwarf stars have no atmospheres. This is fostering new questions about these distant, habitable-zone worlds, and Webb is helping astronomers investigate.

Before #NASAWebb, it had been 30+ years since astronomers looked closely at Neptune. With Webb, scientists imaged the planet’s auroras and studied its atmosphere, including unexpectedly finding a significant drop in temperature—all at a distance.

Black holes galore! That’s what astronomers discovered when #NASAWebb peered into the distant cosmos. These smaller, fainter black holes are more similar to the one in our own galaxy. With Webb, scientists can study the black hole-galaxy relationship over time.

#NASAWebb is clearing up some mysteries about star formation thanks to its infrared capabilities—ideal for seeing the coolest, dimmest stars. ✨ Building on Hubble’s look at the Flame Nebula, Webb revealed new details, including the region’s low mass objects. 🔭 🧪

With #NASAWebb’s infrared sensitivity, astronomers can parse exoplanet atmospheres in great detail, leading to new insights. For example, Webb’s detection of carbon dioxide in system HR 8799’s planets suggests these worlds formed similarly to Jupiter and Saturn. 🔭 🧪
