This image shows what astronomers think is one of the coldest brown dwarfs discovered so far (red dot in middle of frame). The object, called SDWFS J143524.44+335334.6, is one of 14 such brown dwarfs found by NASA's Spitzer Space Telescope using infrared light. Follow-up observations are required to nail down this 'failed' star's temperature, but rough estimates put this particular object at about 700 Kelvin (800 degrees Fahrenheit). In this image, infrared light with a wavelength of 3.6 microns is color-coded blue; 4.5-micron light is red.

Kepler's Supernova Remnant: A View from Spitzer Space Telescope. This Spitzer false-colour image is a composite of data from the 24 micron channel of Spitzer's multiband imaging photometer (red), and three channels of its infrared array camera: 8 micron (yellow), 5.6 micron (blue), and 4.8 micron (green). Stars are most prominent in the two shorter wavelengths, causing them to show up as turquoise.

These images are some of the first to be taken during Spitzer's warm mission -- a new phase that began after the telescope, which operated for more than five-and-a-half years, ran out of liquid coolant. The pictures were snapped with the two infrared channels that still work at Spitzer's still-quite-chilly temperature of 30 Kelvin (about minus 406 Fahrenheit). The two infrared channels are part of Spitzer's infrared array camera: 3.6-micron light is blue and 4.5-micron light is orange. The main picture shows a cloud, known as DR22, bursting with new stars in the Cygnus region of the sky.

Fig. 123.—Belascaris marginata: male; C, female, natural size. A, head, enlarged; B, Toxascaris limbata (Toxascaris marginata). Ascaridse (p. 229).— The body is firm and whitish or pale red in color. The cephalic wings are long, narrow, and somewhat lanceolate. The spicules of the male are not quite equal. Length of female, 6.5-10 cm. (2 1/2-4 inches); male, 4-6 cm. (1 1/2- 2 3/8 inches).
