Spitzer reveals ancient galaxies’ frenzied starmaking

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…

An infrared atlas of interacting galaxies

An infrared atlas of interacting galaxies

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

Spitzer brings 360-degree zoomable view of our galaxy

Spitzer brings 360-degree zoomable view of our galaxy

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

Spitzer space telescope observations reveal unusual infant binary star

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

Spitzer improves measurement of Universe’s expansion rate

Spitzer improves measurement of Universe’s expansion rate

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

Spitzer telescope finds evidence for an exoplanet smaller than Earth

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

Brown dwarfs discovered?

Brown dwarfs discovered?

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:
