NASA’s Webb Reveals Black Hole That Formed Before Its Galaxy

[IMG: Space telescope image showing hundreds of bright objects of different size, color, and shape on the black background of space. Colors range from white to deep red. Shapes include elliptical, spiral, dot-like, dash-like, and arcuate. Many of the large objects near the center of the image are fuzzy white, with bright white cores. Many smaller objects scattered throughout the image are pink to red. Three objects in the central part of the image are called out with small white boxes: A box labeled “C” at about 12 o’clock; one labeled “B” at 3 o’clock; and a box labeled “A” at 4 o’clock.]

Hubble Survey Sets Up Roman’s Future Look Near Milky Way’s Center

[IMG: An observation (labeled “VISTA V V V Survey, Near-infrared) of the Milky Way’s center pointing toward its supermassive black hole, which is labeled Sagittarius A* (pronounced “A star”). At 7 o’clock from center is a small region, outlined with 5 fields of view from the Nancy Grace Roman Space Telescope that are stacked together in a horizontal rectangle. This region is about a third of the image in length and a fifth of the image in width. Within that same region are diagonal lines that alternate between orange and blue. A legend at the bottom left shows two Hubble instruments. One of them, marked with an orange diamond, is labeled “W F C 3 / U V I S.” The other, marked with a blue diamond, is labeled “A C S / W F C.” The background is a field of stars, gas, and dust that appear grey, except the center third that runs from the left to the right of the frame, which is composed of brown filaments of dust and gas. The tiny region surrounding Sagittarius A star appears orange.]

[H1] Who We Are

[IMG: Space image]

[H2]
History and Timeline

We are the Space Telescope Science Institute in Baltimore, Maryland, operated by the Association of Universities for Research in Astronomy. We help humanity explore the universe with advanced space telescopes and ever-growing data archives.
Established in 1981, we have helped guide the most famous observatory in history, the Hubble Space Telescope.  Since its launch in 1990, we have performed the science operations for Hubble. We also lead the science and mission operations for the James Webb Space Telescope (JWST), which launched on December 25, 2021. We will perform parts of the science operations for the Nancy Grace Roman Space Telescope, in formulation for launch in late 2026, and we are partners on several other NASA missions. Our staff conducts world-class scientific research; our Barbara A. Mikulski Archive for Space Telescopes (MAST) curates and disseminates data from over 20 astronomical missions; and we bring science to the world through internationally recognized news, education, and public outreach programs.

[H3]

[H1] What We Do

[IMG: The tip of the wing of the Small Magellanic Cloud galaxy]

STScI continues to expand the frontiers of space astronomy.
We use our scientific and technical expertise to realize operational efficiencies among the Hubble, Webb, and Roman missions. Our teams develop science synergies that enable complementary observing programs using these facilities. We aim to excel in the science operations of NASA’s current and future astrophysical flagship missions, and we provide open access to high-quality, multi-mission archival data. We work with the astronomy community to optimize our current strategies and plan for future missions.

[H3]
Hubble Space Telescope
We are the science operations center for the Hubble Space Telescope, which launched on April 24, 1990. Our work spans the lifecycle of a scientific proposal for Hubble observations, helping to turn great science ideas into great science. We also share discoveries through various outreach endeavors and archive the mission data for future research.

[IMG: Illustration of Hubble Space Telescope]

[H3]
James Webb Space Telescope
As the science and mission operations center for the James Webb Space Telescope, which launched on December 25, 2021, STScI develops and maintains software for the observatory as well as for astronomers. We operate and maintain the observatory as well as solicit proposals to use the telescope, schedule observations, provide calibrated scientific data, and curate a data archive that is open to astronomers and the public.

[IMG: Illustration of the James Webb Telescope]

[H3]
Nancy Grace Roman Space Telescope
STScI is the science operations center for the Nancy Grace Roman Space Telescope, planned to launch no later than May 2027. This mission will revolutionize our understanding of dark energy, extra-solar planets, and astrophysics. STScI will schedule and archive all Roman observations, calibrating and producing pipeline-reduced data products for the Wide Field Instrument.

[IMG: Illustration of the Nancy Grace Roman Space Telescope]

[H3]
Barbara A. Mikulski Archive for Space Telescopes (MAST)
We build advanced systems for our high-value astronomical data holdings to maximize the scientific impact of world-class telescopes. The archive focuses on the optical, ultraviolet, and near-infrared, and hosts data from over 20-plus space missions missions, including Webb, Hubble, TESS, Kepler, and the upcoming Roman, and more than 10 ground-based surveys, past and present.

[IMG: MAST logo with composite image shows a ghostly ring of dark matter in the galaxy cluster Cl 0024+17 in the background]

[H3]
Habitable Worlds Observatory
The Habitable Worlds Observatory (HWO) is the next NASA flagship astrophysics mission that will follow the Nancy Grace Roman Space Telescope. HWO will be a large ultraviolet/optical/infrared space telescope engineered to identify habitable, Earth-like planets around nearby sun-like stars, in addition to conducting ground-breaking investigations across the full range of astrophysical science.

[H3]
User Committees
STScI supports user committees for its missions that serve as a key interface between the operating agencies (NASA/ESA/CSA) and the worldwide user community. The committees meet on a regular basis, typically twice a year, and provide feedback to STScI and the mission senior project scientists on all aspects of observatory operations.

[IMG: Two observations of a portion of the galaxy NGC 628 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is roughly centered and the galaxy’s arms appear to rotate counterclockwise. The spiraling filamentary structure looks somewhat like a cross section of a nautilus shell. In Webb’s image, the spiny spiral arms are composed of many filaments in shades of orange, with prominent dark gray or black “bubbles,” and there is a blue haze near the core. In Hubble’s image, the spiral arms are a mix of bright blue star clusters, pink star forming areas and dark brown dust lanes, and the core is a pale yellow.]
