Observations by NASA's Spitzer Space Telescope have revealed wild atmospheric changes on a well studied exoplanet -- changes that could be driven by extreme volcanic activity.
Astronomers have taken a census of distant spiral galaxies to help us understand what our Milky Way may have looked like in the distant past, also providing us with an invaluable look at the evolution of our own solar system.
For the first time, astronomers have combined the observational power of a ground-based survey with a space telescope to measure the distance to a stellar-mass object that was detected through a chance microlensing event.
NASA's Spitzer Space Telescope, which views the cosmos in infrared light, has taken a fresh look at the beautiful Flame Nebula, revealing some fascinating features that would otherwise remain invisible.
Scientists believe they have spotted a rocky planet in the making around a young, sun-like star 1,200 light years away in the constellation Vela.
No matter how advances a hypothetical extraterrestrial civilization becomes, they will still generate a heat signature that we may be able to detect. Continue reading →
NASA's Spitzer Space Telescope has uncovered the darkest cloud of interstellar dust and gas ever seen; it is so dense that even background infrared radiation is blocked, casting an ominous interstellar shadow. Continue reading →
NASA's Spitzer Space Telescope has helped solve an infrared mystery surrounding baby star systems that has puzzled astronomers since the 1980s. Continue reading →
