This week’s image is from NASA’s Astronomy Picture of the Day. It is a composite image from the James Webb Space Telescope (JWST) and the Hubble Space Telescope showing Messier 64 (M64), which is a spiral galaxy about 17 million light-years away.

Here is a little more information from NASA explaining what you are seeing here:

Sometimes where Hubble finds darkness, Webb sees light. An example is today’s composite images of Messier 64 (M64), a nearby spiral galaxy of many names. The dark band of dust partially blocking its bright core earned it the moniker “the Black Eye Galaxy.” Webb’s Mid-InfraRed Instrument (MIRI) sees that dust, shown in red, as it absorbs and re-emits light from surrounding newborn stars. These young stars are embedded in pink star-forming regions in the secondary Hubble-only image. M64’s inner and outer gas regions counter-rotate, creating regions of increased star formation where the two gas “currents” meet and compress. A merger between M64 and a smaller galaxy was likely the cause of the opposing motion of the outer gas. Spiral galaxies were once thought to have peaceful histories. M64 was key evidence that spiral galaxies, including the Milky Way, can and do experience mergers. Webb’s view of M64 will tell astronomers about the structure, motion, and composition of the galaxy’s dust and add context to the galaxy’s merger history and evolution.

The image above shows the Jodrell Bank Lovell Radio Telescope located in England. The Brits plan to shut this telescope down in 2028 as part of budget cuts.

First commissioned in 1957, parts of the telescope came from the World War 1 decommissioned battleships HMS Revenge and HMS Royal Sovereign. In 2019, the telescope was awarded UNESCO World Heritage Site status.

The BBC noted that the Jodrell Bank Lovell Radio Telescope was the only facility in the Western World able to track Sputnik in 1957. Among many other accomplishments, it was also instrumental in confirming the existence of pulsars as well as proving Einstein’s theory of relativity.

Talk about eerie. This week’s image is from the NASA/European Space Agency’s (ESA) Hubble Space telescope. The ghostly image shows nebula LHA 120-N44, or N44, which is about 160,000 light-years away. It is within the Large Magellanic Cloud that orbits our galaxy.

Here is more from NASA describing what you are seeing:

N44 is dominated by two features: a vast central void and a shell of dense, dusty gas. The central void is a ‘superbubble’ spanning roughly 210 by 140 light-years across. The glittering stars at the center of the void are responsible for its creation; through their powerful stellar winds and explosive supernovae, these stars expelled much of the gas from which they were born.

When the stars of N44’s central star cluster swept away this gas, the expelled gas compressed and formed a shell around the superbubble. New stars are forming in this compressed gas shell, making N44 an interesting target for astronomers who are using the nebula to study how stars form in this environment. Their goal is to understand how long it takes from the collapse of cold gas clouds into dense knots to the moment nuclear fusion ignites in the heart of a newborn star.

This week’s images of 16 galaxies are from a variety of NASA telescopes. The galaxies are generally sorted into three types – spiral, elliptical, and irregular. For example, the Milky Way galaxy is a spiral galaxy, whereas Centaurus A (Cen A above) is a giant elliptical galaxy and NGC 1569 (also above) is a compact dwarf irregular galaxy.

Earlier this week, NASA released the image above showing the crater created by a SpaceX Falcon 9 rocket’s upper stage. The upper stage was part of an earlier SpaceX mission from January 2025 that launched the Firefly Blue Ghost 1 mission. This lunar image was captured by NASA’s Lunar Reconnaissance Orbiter between August 11 and 12.

NASA explained the complex process needed to locate the new crater:

Finding the impact site took global coordination among experts and hobbyists. Independent astronomers first identified the rocket’s trajectory using publicly available data. NASA’s Center for Near Earth Object Studies, which tracks natural objects that could pose hazards to Earth for the agency’s Planetary Defense program, used this opportunity to test and validate tools and techniques for predicting impacts.

Based at NASA’s Jet Propulsion Laboratory in Southern California, the center incrementally refined the trajectory until identifying the location of impact, which it provided to the Republic of Korea for their Korea Pathfinder Lunar Orbiter (Danuri) team. The team used the high-resolution LUTI camera on Danuri a few hours later to image the crater, finding the prediction was accurate to about 0.6 miles.

After capturing images of the crater, the Danuri mission sent coordinates to NASA’s LRO team to help refine their follow-up imaging sequence. Comparing their new crater images with the pre-impact images, the LRO team updated the crater center coordinates: 19.4759°N, 266.7138°E, 511 meters elevation.
