Mission engineers confirmed at about 2:30 p.m. PST (5:30 p.m. EST) Thursday the spacecraft was placed in safe mode, ceasing all science operations.
Spitzer Space Telescope Ends Mission of Astronomical Discovery
Spitzer, designed to reveal the far, cold and dusty side of the universe, made discoveries its designers never even imagined, including a previously unseen ring of Saturn.
10 Things Spitzer Taught Us About Our Solar System
One of NASA's four Great Observatories, Spitzer launched on Aug. 25, 2003, and has studied the cosmos in infrared light. Its breathtaking images have revealed the beauty of the infrared universe.
NASA Says Goodbye to One of Agency's Great Observatories
Engineers did not have exoplanet science in mind when they designed the Spitzer Space Telescope in the 1990s, but thanks solid engineering, Spitzer’s observational powers were used far beyond original expectations.
10 Things Spitzer Taught Us About Exoplanets
An emerging idea, bolstered by three decades of science, is that there are "Goldilocks stars" — not too hot, not too cool, and above all, not too violent to host life-friendly planets.
Goldilocks Stars Are Best Places to Look for Life
This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror.
NASA Visualization Shows a Black Hole's Warped World
Scientists are working with powerful space telescopes to track down specific types of black holes that may hold clues to the formation of the universe.
Black Hole Seeds Missing in Cosmic Garden
The discovery of a dizzying variety of planets and planetary systems is prompting a wholesale re-evaluation of what it takes for a planet to be habitable.
Oceans, Beaches, Cosmic Shorelines: Our Changing Views of Habitable Planets
After nearly 16 years of exploring the cosmos in infrared light, NASA's Spitzer Space Telescope will be switched off permanently on Jan. 30, 2020.
How NASA's Spitzer Has Stayed Alive for So Long
To hunt for exoplanets, the flowerlike shade would need to stay aligned with a space telescope over vast distances. Recent work demonstrates how that's possible.
Starshade Would Take Formation Flying to Extremes
In this large celestial mosaic taken by NASA's Spitzer Space Telescope, there's a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust.

Astronomers have crossed an important threshold in revealing a discrepancy between key techniques for measuring the universe's expansion rate. New theories may be needed to explain the forces that have shaped the cosmos.
Mystery of the Universe's Expansion Rate Widens With New Hubble Data
A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes.
Black Hole Image Makes History; NASA Telescopes Coordinated Observations
From precision GPS to batteries for one of the world’s first commercial all-electric airplanes, NASA technology turns up in nearly every corner of modern life.
