To celebrate the 21st anniversary of the Hubble Space Telescope's deployment into space, astronomers at the Space Telescope Science Institute in Baltimore, Md., pointed Hubble's eye at an especially photogenic pair of interacting galaxies called Arp 273. The larger of the spiral galaxies, known as UGC 1810, has a disk that is distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. This image is a composite of Hubble Wide Field Camera 3 data taken on December 17, 2010, with three separate filters that allow a broad range of wavelengths covering the ultraviolet, blue, and red portions of the spectrum.

This image of Galveston was taken on Nov. 23, 2022, from the International Space Station as it orbited 224 miles above Earth. While President Abraham Lincoln issued the Emancipation Proclamation in 1863, word that enslaved people were free did not reach Galveston until well into 1865. When Union troops arrived that year to share the news, spontaneous celebrations broke out in African American churches, homes, and other gathering places. As years passed, the picnics, barbecues, parades, and other celebrations that sprang up to commemorate June 19th became more formalized as freed men and women purchased land, or “emancipation grounds,” to hold annual Juneteenth celebrations.

This NASA/ESA Hubble Space Telescope image features the globular cluster NGC 2005. It’s not an unusual globular cluster in and of itself, but it is a peculiarity when compared to its surroundings. NGC 2005 is located about 750 light-years from the heart of the Large Magellanic Cloud (LMC), which is the Milky Way’s largest satellite galaxy some 162,000 light-years from Earth.
