All spinning objects, from carousels to planets, generate centripetal force. If a planet rotates too fast, that force can pull it apart. Before that happens, the planet will experience “flattening,” or bulging around its midsection, as seen in this animated illustration of a brown dwarf, Jupiter, and Saturn.
Two massive black holes are locked in a dance at the center of the OJ 287 galaxy. The larger black hole is surrounded by disk of gas; it is also orbited by a smaller black hole that collides with the disk, producing a flare brighter than 1 trillion stars.
How do scientists turn data from NASA’s Spitzer Space Telescope into the incredible images we see? It's not as simple as just snapping a picture of the universe.
NASA's Spitzer Space Telescope’s mission concluded on Jan. 30, 2020, at the agency's Jet Propulsion Laboratory in Pasadena, California.
The Spitzer Space Telescope has been observing the universe in infrared light for over 16 years. As the mission comes to a close, we’ll take a look at some of the amazing highlights and the lasting legacy of this incredible observatory.
After 16 years of amazing infrared discoveries throughout the cosmos, NASA’s Spitzer Space Telescope mission is coming to an end
What is infrared light and how do we use it to study the universe? Infrared radiation, or infrared light, is a type of energy that we humans can't see but can feel as heat.
Initially scheduled for a 2.5-year primary mission, NASA's Spitzer Space Telescope has gone far beyond its expected lifetime -- and is still going strong after 15 years.
The Spitzer Space Telescope is one of NASA’s Great Observatories, designed to observe the universe in infrared light. Launched in 2003 with an expected lifetime of five years, Spitzer has succeeded beyond our wildest expectations. This talk will cover engineering feats and technical challenges, as well as recent science highlights. These include science Spitzer was not designed to do, such as the discovery and characterization of seven rocky, potentially habitable planets in the nearby TRAPPIST-1 system.
Get ready to gaze at galaxies through your telescope. Then compare your views to those taken in infrared by the Spitzer Space Telescope.
NASA's Spitzer Space Telescope has uncovered clues about the atmospheres of two planets beyond our solar system. The new finding is a stepping stone to eventually studying signs of life on other worlds. It represents a significant step toward being able to detect possible life on rocky planets beyond our solar system.
