TOMORROW (Sept. 17, 7 p.m. ET): STScI's Dr. Néstor Espinoza will explore some of the most exciting findings #NASAWebb is unveiling about the atmospheres of distant exoplanets. 🔭 🧪 youtube.com/live/i466qvWBQ…

This Hubble image shows interacting galaxies AM 1054-325. The clusters of stars born from the galaxy merger appear like a string of pearls. Formations like these were common in the early universe. Credit: NASA, ESA, STScI, Jayanne English (University of Manitoba). 🔭 🧪

A nearby, burned-out star is eating a fragment of a Pluto-like object. Only Hubble could identify that this is taking place with its unique ultraviolet vision: bit.ly/4mZk6sx 🔭 🧪

See the size of two protostellar jets imaged by #NASAWebb. The first is an large jet located in Sh2-284. The outflows from the massive protostar are 8 light-years long. In comparison, a jet the nearby region of Rho Ophiuchi is one light-year long. Credit: NASA/ESA/CSA/STScI

Let’s explore two different views of a spiral galaxy. When it comes to NGC 628, #Hubble and #NASAWebb’s images show a contrast between hot stars in visible light, and cool stars and dust in infrared light: bit.ly/42XwnGj 🔭 🧪

This zoom-in video shows the location of the young star cluster Pismis 24 on the sky, where it transitions to the stunning image captured by #NASAWebb. Credit: Alyssa Pagan (STScI), NASA, ESA CSA, STScI. 🔭 🧪

Did you miss last week's Deep Space Dialogues with STScI's Nestor Espinoza, as he chatted about atmospheres of distant exoplanets? Watch it now and learn about how #NASAWebb is dramatically changing our understanding of planetary systems in the cosmos youtube.com/live/i466qvWBQ…

STScI staff took part in this year’s “Astronomy Festival on the National Mall” on Saturday, Sept. 20, in Washington, D.C. They answered questions about new astronomical discoveries by the James Webb Space Telescope and careers in science. Credit: STScI

This visualization of the Scorpius constellation in three dimensions reveals how the stars in the sky become distorted when viewed from a new perspective. youtu.be/Wk0A0HHd568

The Sagittarius B2 star-forming region in the center of our Milky Way looks dramatically different when seen in the near-infrared (more stars) versus mid-infrared (more gas and cosmic dust) light captured by #NASAWebb: bit.ly/48pUVLe 🔭 🧪

This galaxy has a megamaser! It acts like an astronomical laser, with “beams” of microwaves (not visible light) sent out by the bright yellow nuclei. Hubble observed the galaxy, IRAS 16399-0937, in 2016. It's 370 million light-years away. 🔭 🧪 Credit: ESA, NASA; Judy Schmidt.

Take us out to the ballgame! Recently, Space Telescope Science staff took a break from looking at the stars to look at the Baltimore Orioles at play. Project manager Yong Taing was invited onto the field to represent the large group as a “Heavy Hitter.” Credit: STScI.

#NASAWebb provides high-resolution details of Herbig-Haro 49/50—an outflow from a nearby still-forming star and background galaxies. Webb reveals the fuzzy object at the tip of the outflow in the Spitzer image is actually a distant spiral galaxy: webbtelescope.org/contents/media…

STScI's Alyssa Pagan says that there is a methodology for dealing with the electromagnetic spectrum: “In terms of assigning color, we generally do some standard chromatic ordering because it has the most scientific value and meaning in it.” spie.org/news/photonics…
