This Hubble image of the dynamic blue-green planet Neptune reveals a huge dark storm (top center) and the emergence of a smaller dark spot nearby (top right). The giant vortex, which is wider than the Atlantic Ocean, was traveling south toward certain doom by atmospheric forces at the equator when it suddenly made a U-turn and began drifting back northward. Hubble’s Wide Field Camera 3 (WFC3) captured this visible-light image on January 7, 2020, the same time a slightly smaller dark spot mysteriously appeared nearby. That spot then vanished a few months later. The smaller feature may have been a piece of the giant storm that broke off as the larger vortex approached the equator. The large storm is the fourth transient dark spot Hubble has observed since 1993. NASA’s Voyager 2 spacecraft first imaged two dark features in Neptune’s southern hemisphere in 1989 as Voyager flew by the distant planet. Those storms had disappeared by the time Hubble looked at Neptune in 1994. However, Hubble detected two new dark spots in the planet’s northern hemisphere in 1994 and 1996.

This Hubble images shows Caldwell 45, a spiral galaxy located 59 million light-years away in the constellation Boötes. Also known as NGC 5248, this galaxy is notable for the ring structure around its nucleus. These nuclear rings are characterized by hot spots of starburst activity. Caldwell 45 was discovered by astronomer William Herschel in 1784. The galaxy has an apparent magnitude of 10 and can be spotted using a small telescope, though it won’t appear very bright. A larger telescope is needed to make out the galaxy’s spiral arms. The best time of year to observe Caldwell 45 is during the northern hemisphere’s spring and the southern hemisphere’s autumn. This stunning image of Caldwell 45 is a composite of observations made by Hubble’s Wide Field Camera 3 (WFC3) and Wide Field and Planetary Camera 2 (WFPC2) in visible, infrared, and ultraviolet light. It captures the glowing red clouds where new stars are forming, scattered along the galaxy’s winding arms. These observations of Caldwell 45 were made to help astronomers learn more about gas in the galaxy’s starburst regions, as well as to better understand the structure of its nuclear rings.
