The European Space Agency successfully tested a solar-sail-type device to speed up the deorbit time for a used cubesat carrier in Earth orbit. The so-called breaking sail, the Drag ATincrease WDrbiting System (ADEO) was deployed from an ION satellite carrier in late December 2022. Engineers estimate the sail will reduce the time it takes for …

Oddity Discovered on Saturn’s Moon Enceladus Scientists have made a surprising discovery on Saturn’s small ice-covered moon, Enceladus. A soft, feather-like substance was detected in the icy crust of the celestial body. A soft, feather-like substance was detected in the icy crust of the celestial body. Researchers say these are snow-like particles. SURFACE COVERED WITH …
IBM and NASA’s Marshall Space Flight Center today announce a collaboration to use IBM’s artificial intelligence (AI) technology to discover new insights in NASA’s massive trove of Earth and geospatial science data. Tea joint work will apply AI foundation model technology to NASA’s Earth-observing satellite data for the first time. Foundation models are types of …

The late Stephen Hawking once said that we should all remember to look up at the stars and not down at our feet. It admittedly takes a lot of imagination and perhaps even some faith to remember that as big as our world is, we really are just a grain of sand on the stellar …

Kathleen Bertrem of VRT’s archives mentioned in late December 2022 that finding this historic material was like “looking for a needle in a haystack” due to the company misclassifying its extensive files. Nevertheless, the television channel found among its archives the tape of an interview in French that producer Jerome Verhaeghe conducted with Lemaitre on …

A newly released image from NASA’s James Webb Space Telescope shows a crowded field of galaxies and stars, with a distant spiral galaxy standing out in stunning detail. The large galaxy that sits at the bottom of the image, LEDA 2046648, is so clear in the James Webb Space Telescope (JWST or Webb) image that …

Paleontologist Matt Friedman was surprised to discover a remarkably detailed 319-million-year-old fish brain fossil while testing out micro-CT scans for a broader project. “It had all these features, and I said to myself, ‘Is this really a brain that I’m looking at?’” says Friedman from University of Michigan. “So, I zoomed in on that region …
