The Spiderweb Galaxy - which spans some 3 times the diameter of our Milky Way - is forming inside a cluster of protogalaxies, in a dense soup of molecular gas.
The moon passed Venus Friday evening, but there's more to come. Wonderful photos here! Thanks to all who submitted. Keep watching this post for more photos.
The moon is sandwiched between very bright Venus and fainter, reddish Mars this evening. Watch for them in the sunset direction, shortly after the sun goes down.
Asteroid 2015 TC25 is small enough to be straddled by a person, reminiscent of the iconic bomb-riding scene in the movie Dr. Strangelove. It swept between us and the moon a year ago.
Did you see the very young waxing crescent moon on November 30? It'll be easier to see on December 1, low in the west after sunset, below a very bright object ... Venus!
These strange galaxies have 1,000 times fewer stars than the Milky Way, yet occupy a large space. Astronomers used an advanced computer simulation to show that supernova explosions helped create them.
In a recent study, when researchers asked children to draw a scientist, the children most often depicted a bald, middle-aged man in a white coat. More study results here.
The International Astronomical Union - which has given itself responsibility to name and define things in space - has now joined the rest of us in recognizing traditional star names.
Deborah Byrd (asteroid 3505 Byrd) helps edit EarthSky.org and is a frequent host of EarthSky videos. Deborah created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Prior to that, she had worked for the University of Texas McDonald Observatory since 1976, and created and produced their Star Date radio series. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named in her honor in 1990, a Public Service Award from the National Science Board in 2003, and the Education Prize from the American Astronomical Society in 2020. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
