                        Astronomy Picture of the Day

    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.

    The buildings of a city are seen past a dark waterway. Over the city
   are some dark clouds and above that, blue sky. In the blue sky, partly
      obscured by some of the clouds, is a comet with a very long tail,
       running from the middle to the top of the frame. Please see the
                 explanation for more detailed information.

   Explanation: What's that in the sky? Above the city, above most clouds,
   far in the distance: it's a comet. Pictured, the impressive tail of
   Comet C/2024 G3 (ATLAS) was imaged from Bras+¡lia, Brazil four days ago.
   Last week the evolving comet rounded the Sun well inside the orbit of
   planet Mercury, going so close there was early concern that it might
   break up -- and recent evidence that it really did. At one point near
   perihelion, Comet ATLAS was so bright that sightings were even reported
   during the day -- over the bright sky near the Sun -- by careful
   observers. Over the past few days, Comet ATLAS has developed a long
   tail that has been partly visible with unaided eyes after sunset, most
   notably in Earth's southern hemisphere.
