Irregular dwarf galaxy Sextans A, 4.5 million light-years away, forms stars in a gumdrop-shaped area just 5,000 light-years wide. Despite its small size, it's part of the local group of galaxies including the Milky Way and Andromeda.

Irregular Dwarf Galaxy Sextans A

Grand spiral galaxies often seem to get all the attention, flaunting young, bright, blue star clusters and pinkish star forming regions along graceful, symmetric spiral arms. But small galaxies form stars too, like irregular dwarf galaxy Sextans A. Its young star clusters and star forming regions are gathered into a gumdrop-shaped region a mere 5,000 light-years across. Seen toward the navigational constellation Sextans, the small galaxy lies some 4.5 million light-years distant. That puts it near the outskirts of the local group of galaxies, that includes the large, massive spirals Andromeda and our own Milky Way. Brighter Milky Way foreground stars appear spiky and yellowish in this colorful telescopic view of Sextans A.

A Geo-Storm Level 2 is in effect this evening. Even Columbus OH is showing levels of 12% of viewing ability. If you are in dark skies above this region and near the great lakes take a few long exposure photos with your cell phone with cameras pointed North. You may get some views!

erm... am I the only one who sees a ghostly profile rather than teacup here?!

A Hubble Space Telescope image of the Teacup Galaxy, featuring a bright white core surrounded by swirling, faint blue gas. A vivid green, glowing ring of gas appears , shaped like a loop, is in the center left of the image. The surrounding space is dotted with distant galaxies and stars.

"A mere decade ago, astronomers knew of just 62 #moons around #Saturn. Today the ringed #planet boasts a staggering 274 official satellites. That’s more than any other world in the solar system—and far too many for most people to keep track of. Astronomer Edward Ashton is no exception, even though he has helped to discover 192 of them—he thinks that’s the total, anyway, after pausing to do some mental math."
