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.
