Spin through a 360-degree view of the stars in the Ursa Major constellation! 🔭 youtube.com/shorts/Us6Mc1H…

Dr. Julia Roman-Duval delivers a talk on how the Habitable Worlds Observatory's anticipated ultraviolet capabilities will help astronomers understand the cosmic build-up of dust in the universe. Dr. Roman-Duval is the Hubble mission office head at STScI in Baltimore. #HWO2025

STScI's Jason Tumlinson spoke this morning about seeking our origins in the universe with the Habitable Worlds Observatory. Scientists from around the world gathered in Washington, D.C., to discuss the search for signs of life on planets orbiting other stars. #HWO2025

The Habitable Worlds Observatory would be the first telescope designed specifically to search for signs of life on planets orbiting other stars. More about the planned observatory: go.nasa.gov/HWO #HWO2025

This animation shows an intermediate-mass black hole capturing and gravitationally shredding a star. youtube.com/watch?v=V7SlqD…

The Hubble and Chandra space observatories have uncovered an elusive type of black hole hidden in the outskirts of a galaxy. Weighing less that 1 million solar masses, it is a missing link in black hole evolution between small and supermassive black holes: bit.ly/3TNAEqw

This dreamy, foam-like scene is a portion of the Horsehead Nebula imaged by #NASAWebb in 2023. Webb shows some of the “mane,” which is composed of dusty silicates and soot-like molecules, in great detail: bit.ly/3HBSwBM

🐾 An image of the Cat's Paw Nebula by #NASAWebb was released this month. This visualization explores a subset of toe bean-reminiscent structures within a section of the nebula, a massive, local star-forming region located about 4,000 light-years away. youtube.com/shorts/q7nSure…

🪐 Use these ViewSpace Interactives to spy newly forming stars hidden inside giant clouds of gas and dust, search for pulsars in the remains of exploded stars, witness the effects of galaxy collisions, and more. viewspace.org

TOMORROW: Don’t miss out on this opportunity to speak with the real scientists who work on Webb, this Saturday, July 19, at the Maryland Science Center in Baltimore. 🔭 🧪

Hubble’s exquisite sensitivity and resolution were instrumental in uncovering the secrets of NGC 346’s star formation. Research shows the stars are spiraling toward the center of the cluster due to a stream of gas from outside the cluster. Credit: NASA, ESA.

The largest photomosaic of the Andromeda galaxy, assembled from Hubble observations, took more than 10 years of data collecting and was created from more than 600 snapshots! ➡️ And it's available for download in really large sizes: go.nasa.gov/44Uvyhc

This #NASAWebb view of dark cloud L1527 is a reminder to trust the process. ⏳ At the “neck” of the “hourglass” is a hidden protostar—a star in the making. Webb captures the varying thickness of dust, the molecular hydrogen filaments, and more: bit.ly/4n0SuUs

📢 Have questions about the Nancy Grace Roman Space Telescope? You can ask our speakers Dr. Kristen McQuinn and Robyn Sanderson in advance! We will address them during tonight's Deep Space Discussion! Leave your questions in the chat area of the YouTube page.

TONIGHT, 7 p.m. ET: #NASARoman is NASA’s next large strategic mission. STScI's Dr. Kristen McQuinn will tell us how Roman is set to chart the depths of space and time and forge the path towards Earth 2.0. youtube.com/live/2NpN8aejy…

Zoom through space to the Cat’s Paw Nebula. This video continues to a section of the Cat’s Paw, which gradually transitions to the stunning image captured by #NASAWebb in near-infrared light. youtu.be/pERNACvXRRw

NEWS: We may be witnessing the formation of a new supermassive black hole. #NASAWebb shows the Infinity Galaxy has a growing black hole between two galactic nuclei. It may have formed there through direct collapse of a gas cloud: webbtelescope.pub/4nQlWwI
