In general, this\nclassification agrees with the location expected in IRAC-MIPS color-color\ndiagrams for these objects. We find that the evolved disk systems are mostly a\ncombination of objects with optically thick but non-flared disks, suggesting\ngrain growth and/or settling, and transition ...
GLIMPSE360 will map the remaining 187 degrees of the Galactic Plane that have not been previously observed with the Spitzer Space Telescope. Thus the survey will cover longitude l=65-265.5 degrees excluding l 102-109 and l 76-82. The latitude range will be 3.1 degrees, wider than the previo...

The location of the GRB hosts was determined by aligning the Spitzer images against images of the afterglow from the Swift UV/optical telescope (060223A and 060522) and the Gemini Multi-Object Spectrograph on the Gemini-north 8-m telescope (060510B). For the ...

The Spitzer Telescope launched 16 years ago, in August 2003. To celebrate its sweet 16, NASA has shared 16 of the most beautiful space images captured by the infrared telescope. In the image above, blue hues represent visible light, while red and green represent infrared light. ...
This image from NASA'S Spitzer Space Telescope shows the location and apparent size of the Perseus Molecular Cloud in the night sky. Located on the edge of the Perseus Constellation, the collection of gas and dust is about 1,000 light-years from Earth and about 500 light-years wide. Credit...
Astronomers using NASA's Spitzer Space Telescope have observed that planetary systems – dusty disks of asteroids, comets and possibly planets – are at least as abundant in twin-star systems as they are in those, like our own, with only one star. Since more than half of all stars are twi...
We present 5.2-37.2 渭m spectroscopy of the edge-on circumstellar disk CRBR 2422.8-3423 obtained using the Infrared Spectrograph (IRS) of the Spitzer Space Telescope . The IRS spectrum is combined with ground-based 3-5 渭m spectroscopy to obtain a complete inventory of solid-state material ...
