Dark Clouds in Rosette Nebula

A tiny portion of the Rosette Nebula. Very dark gray material shaped like a triangle or shark fin extends from just below top left all the way down to the lower right corner and back up toward the top right.

This is a Hubble Space Telescope photo of a small portion of the Rosette Nebula, a huge star-forming region spanning 100 light-years across and located 5,200 light-years away. Hubble zooms into a small portion of the nebula that is only 4 light-years across (the approximate distance between our Sun and the neighboring Alpha Centauri star system.) Dark clouds of hydrogen gas laced with dust are silhouetted across the image. The clouds are being eroded and shaped by the seething radiation from the cluster of larger stars in the center of the nebula (NGC 2440). An embedded star seen at the tip of a dark cloud in the upper right portion of the image is launching jets of plasma that are crashing into the cold cloud around it. The resulting shock wave is causing a red glow. The colors come from the presence of hydrogen, oxygen, and nitrogen.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    06:33:45
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    +04:59:54
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Monoceros
  • Distance
    DistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
    5,200 light-years
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Image is about 2.7 arcmin across (about 4 light-years)

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

These images were acquired by the WFC3 Instrument on the Hubble Space Telescope. The color results from assigning different hues (colors) to a monochromatic (grayscale) image. In this case, the assigned colors are: Blue: F438W+F502N, Green: F555W+F656N, Red: F814W+F658N

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
