A deep look back to the early universe by NASA's Spitzer Space Telescope has revealed a surprisingly rowdy bunch of galaxies. Within a large galaxy sample, Spitzer witnessed around 15% of galaxies undergoing bouts of extreme starmaking, called starbursts. The…
Most galaxies, including our own Milky Way, have been influenced by an interaction with another galaxy at some time in their past. Interactions between galaxies can trigger an increase in star-formation activity as well an increased level of activity around the nuclear
Touring the Milky Way now is as easy as clicking a button with new zoomable, 360-degree mosaic. The star-studded panorama of our galaxy is constructed from more than 2 million infrared snapshots taken over the past 10 years by NASA's Spitzer Space
NASA's Hubble, Spitzer and Chandra space telescopes are teaming up to look deeper into the universe than ever before. With a boost from natural "zoom lenses" found in space, they should be able to uncover galaxies that are as much as 100 times
NASA’s Spitzer space telescope observed a rare phenomenon – an infant binary star behind a dense disk and envelope of dust 950 light-years away from Earth flashes at regular intervals. NASA report published on February 7, 2013 says such phenomenon has been observed
NASA’s Spitzer space telescope’s latest achievement is most precise measurement of universe’s expansion rate, also known as Hubble constant. As per JPL’s press release, it improves by a factor of 3 on a similar, seminal study from the Hubble telescope and brings the
Astronomers using NASA’s Spitzer Space Telescope have detected what they believe is a planet two-thirds the size of Earth. The exoplanet candidate, called UCF-1.01, is located a mere 33 light-years away, making it possibly the nearest world to our solar system that is
Kevin Luhman of Pennsylvania State University in University Park and colleagues have used NASA's infrared Spitzer Space Telescope to detect the glow of what appears to be a brown dwarf at just 30 °C (Astrophysical Journal Letters, DOI:
