A telephoto snapshot of the almost full moon rising above a conspicuous skyscraper in New York city, taken on October 5, 2025. The 56 Leonard Street skyscraper, is also known as the Jenga Tower, as it indeed is reminiscent of a pile of stacked blocks of a Jenga game.

NGC 7380: The Wizard Nebula

Credit: Nevenka Blagovic Horvat & Miroslav Horvat

star.ucl.ac.uk/~apod/apod/ap25

Located only 8,000 light years away, the Wizard nebula, featured here, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star-forming region spans 100 about light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

Through a gravitational lens effect caused by a massive foreground cluster of galaxies (MACS J0138), multiple images of a perfectly aligned background galaxy (MRG-M0138) are created, including the supernova Encore it hosts. This image was captured by JWST in 2023.

[#MicroLIBS, successor to #ChemCam and #SuperCAM] Based on LIBS (Laser Induced Breakdown Spectroscopy) technology, this new instrument, designed to be carried on board a #drone, will enable the components of the Martian surface to be precisely characterized, thereby acquiring data that is essential for understanding the origin and evolution of many rocks, whether igneous or sedimentary.
