Baltimore City Public Schools alumni carry a universe-sized impact. Decades before contemporary engineers took the reins to operate cutting-edge observatories, City Schools trailblazers were pioneering technologies and shaping critical NASA missions. https://t.co/jmtJW5hIa3 5.5K views · 20 likes · 4 reposts · 0 replies Open on X →

On Tuesday, September 22, Dr. Emily Rickman (European Space Agency and Space Telescope Science Institute) will chat about #NASARoman's coronagraph instrument, which will help scientists continue their dive into the unknown of imaging alien worlds. https://t.co/fg9hEGa0E8 9.6K views · 45 likes · 9 reposts · 3 replies Open on X →

Scientists call this region the Extreme Outer Galaxy due to its location at the edge of our Milky Way. It contains two massive molecular clouds from which clusters of stars are actively forming, as captured in this #NASAWebb image: https://t.co/BiJBsbaKMZ https://t.co/VIVwST7PER
A star-forming region. At center right is a compact star cluster composed of luminous red, blue, and white points of light. Faint jets with clumpy, diffuse material extend in various directions from the bright cluster. Above and to the right is a smaller cluster of stars. Translucent red wisps of material stretch across the scene. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin disks.

STScI scientists are members of the collaboration that has been awarded the 2027 Berkeley Prize for their work with the UNCOVER project. This #NASAWebb program revealed “little red dots” are dusty black holes in the early universe: https://t.co/pXH45vZ2ad https://t.co/kvcy7Z7bdC
A crowded galaxy field on a black background, with one large star dominating just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many others are red or orange. Even without zooming in, different galaxy shapes are detectable, like spirals, ovals, and arcs.

Hubble has observed many Messier catalog items over 35+ years, including the Orion Nebula, the Omega Nebula, globular star cluster Messier 75, and galaxy Messier 109. Scroll through Hubble’s Messier images, and find your favorite: https://t.co/G8MuLavcm7 🔭 https://t.co/XO4MGqSjWI
Messier 42: A vibrant and colorful image of the Orion Nebula, showcasing swirling clouds of gas and dust in hues of purple, pink, and orange, dotted with bright stars. The nebula is set against a dark cosmic background.
Messier 17: The Omega Nebula features a dense field of stars and interstellar dust clouds. The image showcases vibrant blues, with bright stars scattered throughout the nebula.
Messier 75: A densely packed star cluster, known as Messier 75 (M75), fills the image. The center radiates brightly with numerous stars, surrounded by a halo of smaller, glimmering stars. The background is black.
Messier 109: A large spiral galaxy with a bright core surrounded by swirling dust and stars. The image depicts various shades of blue, illustrating large dust lanes and bright groups of stars.

@SpaceTelescope Shadow is off-centre a bit, Looks like the collimation screws need to be adjusted. Hopefully you don’t need to send an astronaut with a screwdriver! 164 views · 1 likes · 0 reposts · 0 replies Open on X →

#NASARoman activated the Wide Field Instrument—a 300-megapixel infrared camera that will allow it to explore wide swaths of the cosmos. This test image captures the very first photons of starlight to reach the instrument—taken as performance assessment: https://t.co/PcJoaUJa2b ht
At the top, a grid of 21 panels shows a series of blue images with tiny neon green and yellow circles. A larger image highlights a section of the grid with circular patterns, and an inset presents a detailed star-like diffraction pattern. The colors consist of blue, green, and yellow.

This starry view of the nearby star-forming region IC 348 sits just 1,000 light-years away in the constellation Perseus. Cold clouds of molecular hydrogen gas collapse to form new stars, creating glowing, sculpted scenes like this one. (1/5) 🧵 https://t.co/P9Qo5psWFc
A star-forming region. The left two thirds is blanketed in thick clouds of green and yellow gas and dust that form swirling patterns. Some of the gas is spread into thin, thread-like wisps. The right third shows a black background speckled with stars and multi-colored dots that are distant galaxies. Bright stars are scattered throughout the clouds, with the densest cluster situated in the center. Each is crowned with six long spikes and two shorter spikes created by the optics of the telescope’s mirrors. In the upper right, a couple of hidden stars blast out long, glowing jets of material that glow in blue.

NEW: One of the largest #NASAWebb images released to date reveals a sweeping view of nearby star forming region IC 348, spanning a whopping 31,000 by 38,000 pixels! Look closely, there’s something to discover in every corner of this stellar nursery: https://t.co/LdCQfu8pyp https:

@SpaceTelescope If Webb’s early black holes / little red dots feel too soon: milder dark-matter ripples + a still-hot CMB can force gas to collapse straight into a black hole — before starlight. 1 views · 0 likes · 0 reposts · 0 replies Open on X →
