English: Image of the reflection nebula IRAS 12116-6001. This cloud of interstellar
dust cannot be seen directly in visible
light, but WISE’s detectors observed the nebula at
infrared wavelengths. The bright
bluestar on the right side of the image is the variable star Epsilon Crucis. The colours used in this image represent specific wavelengths of infrared light. The blue colour of Epsilon Crucis represents light emitted at 3.4 and 4.6 microns. The
green-coloured star seen beside Epsilon Crucis is emitting light at 12 microns. This star is IRAS 12194-6007, a
carbon star that is near the end of its life-cycle. Since the infrared wavelengths emitted by this star are longer than those from Epsilon Crucis, it is cooler. The green and red colours seen in the reflection nebula represent 12- and 22-micron light coming from the nebula’s dust grains warmed by nearby stars.
Name: IRAS12116-6001; Epsilon Crucis. Type: Nebula > Reflection; Star > Variable. Distance: 229 light-years (Epsilon Crucis). Temperature: 4148 Kelvin (Epsilon Crucis). Age: 100,00 years
Mass: Approximately 1.42 times more massive than the Sun (Epsilon Crucis). Magnitude:+3.59 (Epsilon Crucis). Position of object (J2000): RA= 12h 14m 21.383s; Dec=-60° 18’ 07.63” (IRAS 12116-6001). RA=12h 21m 21.6193s; Dec=-60° 24’ 04.128” (Epsilon Crucis). Constellation: Crux
Field of View: 1.56 x 1.56 degrees. Orientation: North is 140.68 degrees left of vertical. Color Mapping: Blue=3.4 microns; Cyan=4.6 microns; Green=12 microns; Red=22 microns.
