Tardigrades, commonly known as water bears, may be better suited by a new name: Tardiguardians of the Galaxy. Unlike the fictional ragtag team of unenthusiastic heroes, the microscopic animals are providing real insight into how humans could adapt extraterrestrial resources to support space exploration, as well as whether such resources could help protect against the […] For over 50 years, the Landsat program has provided the longest continuous satellite record of Earth’s land surface from space. Landsat 9, launched in 2021, is the latest mission in this remarkable legacy—building on decades of Earth observation with upgraded technology, including enhanced radiometric resolution, improved signal-to-noise performance, and polar night thermal imaging. Go to […] With a simple motion, a jack-in-the-box-like spring designed at NASA’s Jet Propulsion Laboratory showed the potential of additive manufacturing, also known as 3D printing, to cut costs and complexity for futuristic space antennas. Called JPL Additive Compliant Canister (JACC), the spring deployed on the small commercial spacecraft Proteus Space’s Mercury One on Feb. 3, 2026. […] This striking image from the science camera on ESA’s Jupiter Icy Moons Explorer (Juice) shows interstellar comet 3I/ATLAS spewing dust and gas. The tiny nucleus of the comet (not visible) is surrounded by a bright halo of gas known as the coma. A long tail stretches away from the comet, and we see hints of […] Yale junior Donglin Wu leads a new study showing that some of the biggest stars in the universe shed some of the smallest dust particles. It’s fitting that Wu’s first major scientific journal article as lead author focuses on stardust—tiny solid grains that form from stellar winds, drift into interstellar space, and may eventually become […] Some of the universe’s most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front plows into its surrounding environment. In new research accepted for publication in The Astrophysical Journal, we have discovered what may be the clearest […] Thanks to Fink, a software package created by two CNRS engineers, it is now possible to track millions of transient celestial phenomena observed in the sky by the Vera C. Rubin Observatory in Chile, in real time and with unprecedented precision. Minutes after each image is taken, Fink receives, processes, enriches, and cross-references the data […] NGC 941 is located approximately 55 million light-years away in the constellation Cetus. This faint galaxy is classified as an intermediate spiral, exhibiting characteristics between a barred spiral with a central bar and an unbarred spiral. Go to Source When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact constantly shifting. Satellites, asteroids and interstellar objects pass by. Stars not only shine brightly, they can suddenly burst with energy or explode in bright supernovae. Go to Source […] When we look up at the night sky and see a satellite glide past, we might not consider climate change or the ozone layer. Space may feel separate from the environmental systems that sustain life on Earth. But increasingly, the way we build, launch and dispose of satellites is starting to change that. Go to […] Russian astronomers from Moscow State University have performed photometric, polarimetric, and spectroscopic observations of a young star designated IRAS 21204+4913. Results of the new observations, which were published February 16 on the arXiv preprint server, reveal the eruptive behavior of this star and shed more light on its nature. Go to Source […] Researchers from the Department of Earth Sciences, University of Oxford, have resolved a long-standing debate about the strength of the moon’s magnetic field. For decades, scientists have argued about whether the moon had a strong or weak magnetic field during its early history (3.5–4 billion years ago). Now a new analysis, published in Nature Geoscience, […] Dining on the moon or Mars might seem like a fantasy reserved for science fiction, but researchers are investigating how it could become a reality. Their efforts to recycle plant and human waste into a fertilizer material—turning the barren surfaces of the moon and Mars into fertile fields that might be suitable for extraterrestrial agriculture—are […] Thinking about food systems in deep space likely brings to mind something like The Martian where an astronaut is scratching barely enough food to survive out of potatoes grown in Martian regolith. Or perhaps a fancy hydroponic system on an interplanetary transport ship, with artificial lighting and all the associated technological wizardry. But a new […] Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the […] |
