December 11 Galaxy Orbits in Local Supercluster by:

Astronomers chart galaxy orbits in Local Supercluster "For the first time, we are not only visualizing the detailed structure of our Local Supercluster of galaxies, but we are also seeing how the structure developed over the history of the universe." Find the Geminid meteors' radiant point     The radiant point for this week's Geminid meteor shower - possibly 2017's most spectacular meteor shower - is in the east in mid-evening or overhead by about 2 a.m. Don't miss the Geminids in 2017 Because the meteors' parent object - 3200 Phaethon - is nearby, the 2017 Geminid meteor shower might be awesome! Peak mornings December 13 and 14. All the illions from Cosmos, in order Why? Because we love Carl Sagan. Tonight … Can you see stars' different colors? Late December is the perfect time for noticing the colors of the stars. Our sky chart can help guide your eye.

Find the Geminid meteors' radiant point     If you gaze along a railroad track, you see the illusion of parallel tracks converging in the distance. Like railroad tracks, meteors enter Earth's atmosphere on parallel paths, and they appear to converge at a single point on our sky's dome. This is the shower's radiant point.

Shining sea and sky "When phytoplankton come near the beach, you can see this amazing scene. There is light in the sea and sky," said Mohammad Rouhbakhsh of Iran, who captured this image on December 1. Submit your photo to EarthSky here!
