NASA's Spitzer Space Telescope is a space-based infrared observatory, part of NASA's Great Observatories program (which also includes Hubble, Chandra, and Compton). These podcasts offer information about the science discoveries, astronomy, and more.
Its life Jim, but not as we know it, well at least the building blocks of life. A new study from NASA's Spitzer Space Telescope hints that planets around stars cooler than our sun might possess a different mix of potentially life-forming chemicals.
Young city dwellers on Earth aren't the only ones rushing to suburbia to start families. New observations from NASA's Spitzer Space Telescope suggest that galaxies also prefer to breed stars in the cosmic suburbs.
New observations from NASA's Spitzer Space Telescope suggest that moons like Earth's -- that formed out of tremendous collisions -- are uncommon in the universe, arising at most in only 5 to 10 percent of planetary systems.
Once thought to be the stuff of science fiction, double sunsets may be much more common in the universe than previously believed. Dr. David Trilling discusses the Spitzer Space Telescope's recent results.
Using the Spitzer Space Telescope, astronomers have for the first time discovered what the atmosphere is like on planets outside our solar system! Drs. Sara Seager and David Charbonneau discuss this groundbreaking technique with Robert Hurt.
Hubble's ''Pillars of Creation'' within the Eagle Nebula is one of the most famous astronomical images of all time. But new Spitzer observations by Nicolas Flagey have led to a surprising discovery: they may soon become ''Pillars of Destruction.''
Astronomers have long scrutinized the vast and layered clouds of the Orion nebula, an industrious star-making factory visible to the naked eye in the sword of the famous hunter constellation. Yet, Orion is still full of secrets.
Years before Spitzer was launched into space, the entire mission was cancelled! Dr. George Rieke discusses the incredible story of what brought it back from the dead, and how that information is influencing new infrared telescopes being developed today.
Spitzer has found a supernova remnant that no other telescope has seen. Dr. Patrick Morris discusses his team's discovery of this shy object which can't be detected in visible or even most bands of infrared light.
Are solar systems like our own common in the universe, or is ours an oddball? Dr. Lynne Hillenbrand discusses her work on a project designed to answer this question, and what they have discovered so far.
A supernova may be the ultimate end of a star's life, but this may not be the story's end. Recent Spitzer results hint at new planetary systems arising from the ashes of the old. Dr. Deepto Chakrabarty and Zhongxiang Wang discuss their startling discovery.
Michelle Thaller speaks with Dr. George Helou about a striking new image of Galaxy M82, the discovery of mysterious organic dust clouds around the galaxy, and what they may reveal about the origin of organic material in our own galaxy.
Robert Hurt speaks with Dr. Dean Hines by phone about the discovery of an asteroid belt similar to our own around a very young star, and what that might mean for the abundance of planets in the galaxy.
Observations of our sister galaxy Andromeda reveal a new side to this Milky Way neighbor. Dr. Karl Gordon and Dr. George Rieke discuss Spitzer's fantastically detailed map of its dusty skeleton, previously hidden behind its veil of stars.
Dr. Lin Yan discusses her recent discovery of polycyclic aromatic hydrocarbons (or PAHs) in galaxies when our universe was one-fourth of its current age of about 14 billion years -- long before astronomers previously thought organic compounds could have formed.
