05.26.10 - NASA's Spitzer Space Telescope and radio telescopes are probing the structure of our Milky Way galaxy.
05.20.10 - Our sun may be an only child, but most of the stars in the galaxy are actually twins. The sibling stars circle around each other at varying distances, bound by the hands of gravity.
05.11.10 - In a recent deep excavation, courtesy of NASA's Spitzer Space Telescope, astronomers unearthed what may be the most distant, primitive cluster of galaxies ever found.
04.21.10 - NASA's Spitzer Space Telescope has discovered something odd about a distant planet -- it lacks methane, an ingredient common to many of the planets in our solar system.
04.01.10 - Astronomers have their eyes on a hot group of young stars, watching their every move like the paparazzi.
03.29.10 - A new image from NASA's Chandra and Spitzer space telescopes shows the dusty remains of a collapsed star. The dust is flying past and engulfing a nearby family of stars.
03.17.10 - Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known.
02.09.10 - Artwork inspired by NASA's Spitzer Space Telescope is making an appearance at this year's Winter Olympics in Vancouver, British Columbia.
01.06.10 - Most searches for planets around other stars, also known as exoplanets, focus on sun-like stars.
01.05.10 - NASA's Spitzer Space Telescope has captured an action-packed picture of the nearby Small Magellanic Cloud, a small galaxy that looks like a wispy cloud when seen from Earth.
01.05.10 - For almost two centuries, humans have looked up at a bright star called Epsilon Aurigae and watched with their own eyes as it seemed to disappear into the night sky, slowly fading before coming back to life again.
12.03.09 - The world's largest image of our Milky Way galaxy, taken by NASA's Spitzer Space Telescope, went on display this week at the Adler Planetarium in Chicago.
11.23.09 - NASA's Spitzer Space Telescope has contributed to the discovery of the youngest brown dwarf ever observed -- a finding that, if confirmed, may solve an astronomical mystery about how these cosmic misfits are formed.
11.10.09 - A never-before-seen view of the turbulent heart of our Milky Way galaxy is being unveiled by NASA today. This event will commemorate the 400 years since Galileo first turned his telescope to the heavens in 1609.
11.04.09 - NASA's Spitzer Space Telescope has found a young star with evidence of the same orbital hyperactivity that our planets had before they found their way to the stable orbits they circle in today.
10.20.09 - Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, advancing astronomers toward the goal of being able to characterize planets where life could exist.
10.06.09 - NASA's Spitzer Space Telescope has discovered an enormous ring around Saturn -- by far the largest of the giant planet's many rings.
09.23.09 - Astronomers have witnessed odd behavior around a young star. Something, perhaps another star or a planet, appears to be pushing a clump of planet-forming material around.
08.12.09 - A new study from two of NASA's Great Observatories provides fresh insight into how some stars are born, along with a beautiful new image of a stellar nursery in our Milky Way galaxy.
08.10.09 - NASA's Spitzer Space Telescope has found evidence of a high-speed collision between two burgeoning planets around a young star.
