This NASA/ESA Hubble Space Telescope image released Nov. 5, 2026, provides a lesson in galactic history. The sparkling collection of stars is named Messier 30 (M30) after the French astronomer, Charles Messier, who cataloged M30 and other diffuse objects that might be mistaken for comets in the early telescopes of Messier’s time. M30 lies about 27,500 light-years away in the constellation Capricornus.

Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: It is time to say goodbye to NASA‘s Neil Gehrels Swift Observatory. After nearly 22 years of service, the satellite re-entered Earth’s atmosphere on November 4 at 7:39 EST over the North Sumatra region of Indonesia. The featured image is a mosaic created in 2018 using the first one million images captured by the satellite’s Ultraviolet/Optical Telescope. Swift had a combination of instruments, including an X-ray telescope and a gamma-ray telescope, that worked together to enable humanity to study, in unprecedented detail, the fastest and most energetic explosions in the universe. The most recent solar maximum accelerated the decay of the satellite’s orbit. An innovative mission to rescue Swift by boosting its orbit was not successful. Swift burned on reentry like a shooting star, but the impressive data acquired by the telescope over its mission will continue to bring light to the mysteries of the cosmos for years to come. May it keep inspiring new missions to boldly go into space, explore new data and seek out new science.
Tomorrow’s picture: what’s next?

Tens of millions of years ago, the San Juan River in what is now southern Utah shared some characteristics with today’s Mississippi River. In a bygone geologic era, the San Juan flowed across a relatively flat plain that formed in an ancient marine environment. Unencumbered by rugged terrain, the river was free to take a long, meandering path on its gradual journey downslope.
But this part of the San Juan changed when geologic forces pushed the Colorado Plateau upward. Some experts think that within the later stages of this “still-enigmatic” history, starting around 20 million years ago, the plateau’s rise elevated the San Juan’s headwaters, which increased the river’s gradient and sped its flow. With that, the water’s erosive power intensified, and the river started carving its winding path deeper and deeper through 300-million-year-old rock.
Today, on its westward path to Lake Powell, the San Juan River flows through an impressive series of entrenched meanders, also known as “goosenecks.” An astronaut aboard the International Space Station photographed the stark desert topography on October 6, 2026.
In Utah’s Goosenecks State Park, the river runs through a canyon 1,000 feet (300 meters) deep. In places, it nearly loops back on itself, making horseshoe-shaped bends. One section is so curvy that the river travels 5.5 miles (8.9 kilometers) between two points that are only 1.3 miles (2.1 kilometers) apart as the crow—nay, goose—flies.
While the goosenecks are an unusual geologic wonder to behold by day, the area’s dark skies are a spectacle by night. Goosenecks State Park’s remote, high-desert location and 360-degree views of the sky helped earn it an International Dark Sky Park designation in 2021. According to DarkSky International, features such as the Double Cluster in Perseus and the Messier 24 star cloud in the Sagittarius spiral arm of the Milky Way are visible to the unaided eye from the park. In November 2026, dark skies offer the chance to view several meteor showers, with the Northern Taurids, Southern Taurids, and Leonids reaching their peaks throughout the month.
Astronaut photograph ISS075-E-188830 was acquired on October 6, 2026, with a Nikon Z9 digital camera using a focal length of 400 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 75 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Photo by Bob Wick (BLM), via Flickr. Story by Lindsey Doermann.

City lights from the Midwestern United States to the East Coast sparkle across the landscape a couple of hours before sunrise on Oct. 18, 2026. Major urban areas visible in the photograph include Chicago, Illinois; Detroit, Michigan; and the New York metropolitan region. The International Space Station was orbiting 259 miles above Earth when this photograph was taken.
