Gloucestershire company wins prize for inventing way to produce clean water on moon
- A £150,000 prize for a device that can produce clean water from icy lunar soil has been won by a pair of inventors.
- The solution involves a microwave oven, a motorised device for feeding woodchips into a barbecue, and sound waves.
- The challenge is to produce drinking water from ice-rich regolith around the moon's south pole for future moon missions.
- The winning solution, called the SonoChem system, uses a multi-step contraption to vaporise and purify the water.

James Webb telescope zooms in on bizarre 'Einstein ring' caused by bending of the universe
- The James Webb Space Telescope (JWST) has captured a stunning image of a bizarre astronomical optical illusion.
- The image shows an Einstein ring, which is a distorted view of two distant galaxies in the constellation Hydrus.
- Gravitational lensing caused by a massive object bending light creates the Einstein ring phenomenon, in which a more distant galaxy's light appears as a ring.
- The image was captured by JWST's Near-InfraRed Camera instrument and includes data from the Hubble Space Telescope.

Finding Clues in Ruins of Ancient Dead Star With NASA’s Chandra
- Astronomers are using data from NASA’s Chandra X-ray Observatory to conduct 'supernova archaeology' on a star that self-destructed over a million years ago.
- The remnants of a star that exploded, now part of the system GRO J1655-40, reveal clues about its past.
- The system originally had two stars, with one undergoing a supernova explosion, forming a black hole that exists today.
- The black hole started pulling matter from its companion, emitting material into space through powerful winds.
- By analyzing X-ray data using Chandra, astronomers identified elements in the black hole's winds, revealing the star's past characteristics.
- This 'supernova archaeology' study provides insights into the properties of the star that exploded, aiding future investigations of double star system outbursts.
- The findings were published in The Astrophysical Journal in May 2024 by a team including researchers from NASA and Technion.
- The Chandra program is managed by NASA's Marshall Space Flight Center, with operations handled by the Chandra X-ray Center.
- The visual description includes an artist's illustration of a supernova explosion and a spectrum graph indicating X-ray brightness and wavelengths of elements detected.
- For more information about the Chandra X-ray Observatory, visit NASA's official website or the Chandra X-ray Center's website.

James Webb telescope captures auroras on Neptune for first time ever
- The James Webb Space Telescope (JWST) has captured auroras on Neptune for the first time ever.
- Auroras were detected using the telescope's near-infrared sensitivity and were found near Neptune's mid-latitudes.
- Neptune's magnetic field, being tilted 47 degrees off its rotational axis, causes auroras to appear in unique locations.
- The discovery of auroras on Neptune and the detection of trihydrogen cations indicate the importance of instruments tuned to infrared light.

Saying farewell to Gaia, as the Milky Way-mapping space telescope mission ends
- The Gaia Observatory from the European Space Agency (ESA) has been powered down and sent into a “retirement orbit” around the sun.
- Gaia has created a detailed 3D map of the Milky Way, revealing its structure and uncovering evidence of galactic mergers, new star clusters, exoplanets, and black holes.
- The collected data will continue to be released and analyzed, with a fourth data release planned for 2026.
- As the mission ends, the Gaia team deliberately corrupted the spacecraft's onboard software, overwriting it with a farewell message and the names of the mission contributors.

An AI explains the Quantum Scale actions of “Neutron Decay Cosmology “ — Caleigh Fisher
- The neutron is a dynamic, self-contained flow, existing as a double cover with rotation imparting inertia.
- In low-pressure environments, the neutron's internal flow equilibrium collapses leading to decay.
- Neutron decay is a shift in flow topology rather than a simple particle decay.
- This view eliminates the need for singularities, arbitrary field quantization, or external time.

An AI explains “Neutron Decay Cosmology “. A universal topology and process. -Caleigh Fisher
- Neutron decay plays a crucial role in explaining the expansion and compression in the universe.
- Expansion occurs in deep cosmic voids as free neutrons decay into protons and electrons, leading to a significant volume increase.
- Compression takes place in high-density regions, where electrons are forced into protons, reversing the decay process.
- The concept of Shirley's Surface and a compactified time frame are proposed, highlighting the connection between expansion and contraction in the universe.

Farewell to Gaia after 12 successful years
- The European Space Agency (ESA) powered down the Gaia spacecraft on March 27, 2025, after 12 years of successful operations.
- Gaia's data releases are valuable for astrophysical research, influencing various astronomy disciplines up until the final release in 2030.
- ESA's Gaia spacecraft, launched in 2013, provided significant insights into the Milky Way galaxy through mapping and measuring its components.
- Gaia aimed to create a precise 3D map of the Milky Way and has tracked nearly two billion objects over the past decade.
- Gaia operated from Lagrange Point 2, but due to fuel depletion, ESA ceased its measurements although data releases will continue.
- Gaia will be moved from its current orbit to prevent potential interference with other spacecraft, ensuring its safe retirement.
- Gaia's contributions include spotting asteroids with possible moons, discovering massive stellar black holes, and mapping Milky Way mergers.
- Additionally, Gaia made impactful discoveries beyond the Milky Way, such as stars traversing galaxies and identifying a massive ghost galaxy.
- The Gaia spacecraft's retirement marks the end of an era, with astronomers continuing to analyze its rich dataset for years to come.
- Despite Gaia's operations officially ending, the wealth of data it gathered will fuel new discoveries and advancements in astronomy.
