Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

    [2]The center of the Orion Nebula is seen in infrared light as imaged
   by the James Webb Space Telescope. In the center is the Trapezium Star
    Cluster. The main image is in near infrared light, while the rollover
     image is in mid-infrared light. Please see the explanation for more
                            detailed information.

   Explanation: The Great Nebula in Orion has hidden stars. To the unaided
   eye in visible light, it appears as a small [10]fuzzy patch in the
   [11]constellation of Orion. But [12]this image was taken by the
   [13]Webb Space Telescope in a representative-color composite of red and
   very near [14]infrared light. It confirms with [15]impressive detail
   that the [16]Orion Nebula is a busy neighborhood of young stars, hot
   gas, and dark dust. The [17]rollover image shows the same image in
   representative colors further into the [18]near infrared. The power
   behind much of the [19]Orion Nebula (M42) is the [20]Trapezium - a
   cluster of bright stars near the nebula's center. The diffuse and
   [21]filamentary glow surrounding the bright stars is mostly heated
   interstellar [22]dust. Detailed inspection of these images shows an
   [23]unexpectedly large number of Jupiter-Mass Binary Objects
   ([24]JuMBOs), pairs of Jupiter-mass objects which might give a clue to
   how [25]stars are forming. The whole [26]Orion Nebula cloud complex,
   which includes the [27]Horsehead Nebula, will slowly disperse over the
   next few million years.
