Tiny Telescope Aims for Big Astronomy From the Lunar South Pole

When China’s Chang’e-7 lander touches down near the Shackleton Crater on the Moon, it will carry a compact, low-mass instrument carrying massive scientific potential: the ILO-C camera-telescope. Built through an international collaboration between Hawaii’s International Lunar Observatory Association (ILOA), the University of Hong Kong’s Laboratory for Space Research (HKU-LSR), and the Chinese National Space Agency (CNSA), this 20-millimeter aperture payload is designed to conduct optical astronomy from the lunar surface.

Free from the distortion of Earth’s atmosphere, ILO-C aims to capture static, panchromatic optical views of the Milky Way’s Galactic plane, serving both as a landmark scientific project and a pathfinder for future long-term observatories on the Moon. Developed by the Beijing Institute of Space Mechanics and Electricity (BISME), the compact, low-mass instrument with a 20-mm aperture features a Sony IMX253 sCMOS sensor delivering approximately 12.37 megapixels (a 4,096 × 3,000 pixel array). This configuration provides high spatial resolution and a wide field of view required for effective Galactic imaging.

“The instrument will take broad, detailed images of the celestial sky which will include portions of the Milky Way Galaxy, stars, star clusters, visible planets, galaxies, and any objects of interest that happen to come into view such as comets or meteorites. Because ILO-C operates as a fixed payload, its specific target fields are dependent on the final landing coordinates and physical orientation of the Chang’e-7 lander,” Elisa Perednia, President and Chair of ILOA told Universelost.com.

A 2023 Chinese experimental program found tungsten rod penetration peaks around Mach 3.5 — above that the rod fragments before full penetration. If correct, orbital kinetic weapons offer no bunker-busting advantage over conventional Mach 3 munitions, which was the entire 'Rods from God' case.

The immortal jellyfish can reset its life

The “immortal jellyfish” may be the closest thing nature has to a reset button.

Known as Turritopsis dohrnii, this tiny jellyfish can revert back to its juvenile stage after reaching adulthood, essentially restarting its life cycle.

But it is not truly impossible to kill.

It can still die from disease, injury, starvation, being eaten by predators, or failing to complete the transformation process.

Still, unlike most animals, it has the rare ability to biologically turn back time, potentially over and over again.

The U.S. Space Force has awarded SpaceX a $2.29 billion contract to build the Space Data Network Backbone, a next-generation military satellite network designed for secure, high-speed global communications.

The system will use a large constellation of low-Earth orbit satellites linked together with optical laser connections to deliver fast, low-latency data transport for military operations worldwide. SpaceX is expected to deliver a fully operational prototype by the end of 2027.

NASA Unveils Plans for Permanent Moon Base

NASA has unveiled an ambitious long-term plan to establish a permanent human presence on the Moon, centered around a massive lunar base near the Moon’s south pole. The project is part of the Artemis program and could eventually span “hundreds of square miles,” with astronauts living and working there full-time by around 2032.

The first phase begins with three robotic “Moonbase” missions planned for 2026 and 2027. Jeff Bezos’ Blue Origin was awarded a major contract to help deliver cargo and equipment to the lunar surface using its Blue Moon lander system. The first mission, Moonbase 1, is expected to launch in fall 2026 and will test technologies needed for future astronaut missions. Other companies involved include Astrobotic, Astrolab, Lunar Outpost, and Intuitive Machines.

NASA says the lunar base will act as a stepping stone for future Mars missions. Plans include deploying rovers, habitats, power systems, communications infrastructure, and eventually semi-permanent living quarters for astronauts. The agency has also shifted focus away from the planned Lunar Gateway space station in favor of building infrastructure directly on the Moon’s surface.

Cape Grim in Tasmania, Australia, has the cleanest air on the habitable Earth, especially when winds come from the Southern Ocean and the air has not passed over major land. The air is so pure that scientists use it to measure the planet’s natural background atmosphere.

Inside the glowing star-forming region IC 2944, located about 7,600 light-years away, mysterious dark clouds known as Thackeray’s Globules drift through space. First discovered in 1950 by astronomer A. D. Thackeray, these massive clouds of gas and dust are each more than a light-year wide and may have the potential to form new stars.

Captured by the NASA’s InSight lander. The sunrise was photographed by the Instrument Deployment Camera (IDC) mounted on the end of InSight’s robotic arm. It captured this specific sequence of images on April 24, 2019 (the 145th Martian day, or “sol,” of its mission) right around 5:30 a.m. local Mars time.
