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.

Pic of the Week: Galactic Gems

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.

This week’s image is from the U.S. National Science Foundation’s (NSF) National Solar Observatory (NSO). It shows the highest resolution image ever captured of the Sun’s surface. The image was captured by the Inouye Solar Telescope located in Maui, Hawaii.

Here is more from the NSF about this image:

Using the world’s most powerful solar telescope, the NSF Daniel K. Inouye Solar Telescope near the summit of Maui’s Haleakalā, combined with computer simulations, an international team of scientists from the NSO, NSF NCAR High Altitude Observatory (HAO), and the Max Planck Institute for Solar System Research (MPS) found the signature of Kelvin-Helmholtz instability (KHI), tiny swirling patterns like small whirlpools, on the Sun’s surface. Researchers suggest that KHI might be a key reason why the Sun’s outer atmosphere gets so hot, and why magnetic energy builds up and moves around on the Sun. Magnetic energy fuels solar flares and eruptions—the kind of solar activity that can send bursts of energy toward Earth and affect satellites, power grids, and other technology. The discovery opens a new window into the fundamental physics of the Sun and other stars while underscoring the unmatched capabilities of the Inouye Solar Telescope.
