Astronomy Picture of the Day

Explanation: As spring approaches for northern skygazers Comet 12P/Pons-Brooks is growing brighter. Currently visible with small telescopes and binoculars the Halley-type comet could reach naked eye visibility in the coming weeks. Seen despite a foggy atmosphere, the comet's green coma and long tail hover near the horizon, in this well-composed deep night skyscape from Revuca, Slovakia recorded on March 5. In the sky above the Halley-type comet, the Andromeda (right) and Triangulum galaxies flank bright star Mirach, beta star of the constellation Andromeda. The two spiral galaxies are members of our local galaxy group and over 2.5 million light-years distant. Comet Pons-Brooks is a periodic visitor to the inner Solar System and less than 14 light-minutes away. Reaching its perihelion on April 21, this comet should be visible in the sky during the April 8 total solar eclipse.
