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]A picture of the unusual galaxy M82 is on the left, while the center
    is expanding and shown in a JWST image on the right. Many red-glowing
    filaments eminate out from the plane of the spiral galaxy. Please see
               the explanation for more detailed information.

   Explanation: Something strange happened to this galaxy, but what? Known
   as the [9]Cigar Galaxy and cataloged as [10]M82, red glowing gas and
   dust are being cast out from the center. Although this [11]starburst
   galaxy was surely stirred up by a recent pass near its [12]neighbor,
   large spiral galaxy [13]M81, this doesn't fully explain the source of
   the red-glowing outwardly expanding gas and [14]dust. Evidence
   indicates that this material is being driven out by the combined
   emerging [15]particle winds of many stars, together creating a
   [16]galactic superwind. In the [17]featured images, a [18]Hubble Space
   Telescope image in [19]visible light is shown on the left, while a
   [20]James Webb Space Telescope image of the central region in
   [21]infrared light is shown on the right. [22]Detailed inspection of
   the [23]new Webb image shows, unexpectedly, that this red-glowing dust
   is associated with [24]hot plasma. [25]Research into the nature of
   [26]this strange nearby galaxy will surely continue.
