In an effort to bring its vast distances down to Earth, we've shrunk the solar system to the size of a football field.
How Big Is the Solar System?
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
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
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.

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.

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
The forecast for the next solar cycle says it will be the weakest of the last 200 years.
Solar Activity Forecast for Next Decade Favorable for Exploration
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.
