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 starfield is shown with constellations annotated. The band of our
      Milky Way galaxy runs diagonally from the upper left to the lower
   right. Just above the image center is a faint dot that is annotated in
   yellow -- V462 LUPI, a nova that was visible with the unaided eye last
     week and is currently still visible with binoculars. Please see the
                 explanation for more detailed information.

   Explanation: If you know where to look, you can see a thermonuclear
   explosion from a white dwarf star. Possibly two. Such explosions are
   known as [5]novas and the detonations are currently faintly visible
   with the unaided eye in [6]Earth's southern hemisphere -- but are more
   easily seen with binoculars. [7]Pictured, Nova Lupi 2025 (V462 Lupi)
   was captured toward the southern constellation of the Wolf ([8]Lupus)
   last week near the central plane of our Milky Way galaxy. [9]Nova Lupi
   2025 was originally discovered on June 12 and peaked in brightness
   about a week later. Similarly, [10]Nova Velorum 2025, toward the
   southern constellation of the Ship Sails ([11]Vela), was discovered on
   June 25 and peaked a few days later. A [12]nova somewhere in our Galaxy
   becomes briefly visible to the unaided eye only every year or two, so
   it is quite unusual to have [13]two novas visible simultaneously.
   Meanwhile, [14]humanity awaits even a different nova: [15]T Coronae
   Borealis, which should become visible in northern skies and is expected
   to become even brighter.
