Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at birth or, more often, long after they have settled into adulthood. There is an information gap about what happens in the middle.
Some solid materials can cool down or heat up when pressure is applied or released. This behavior enables cooling and heating technologies that do not rely on climate-damaging refrigerant gases. In practice, however, a major obstacle remains: many materials behave differently during heating and cooling, which makes their response difficult to use reliably in real devices. In a study published in the journal Communications Materials, researchers investigate a solid material known for its exceptionally large cooling/heating response (thermal response) under pressure and ask a simple question: can this response be made more reliable? They show that a very small change in composition leads to a clear improvement and use neutron experiments to explain why this improvement occurs.
Richard Dean Bird, who fatally shot Christian County deputies Gabriel Ramirez and Michael Hislope, had a lengthy criminal history, including a history of shooting at police
NASA said Friday it’s adding an extra moon mission by Artemis astronauts before attempting a high-risk lunar landing with a crew.
Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it with a base surface to manufacture small, heat-resistant objects.
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 Earthly contaminants that humans might shed.
Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include so-called spatial light modulators (SLMs), systems that dynamically adjust the position of a light wave within its cycle (i.e., phase), as well as its amplitude or direction across several pixels.
Huron Township officers picked up a pursuit of a woman, believed to be armed, who called in threats to 911, tried to run over officers and ram cruisers, and fled into a landfill
The suspect was initially charged with felony assault on a police officer; the DA’s office charged him with harassment and obstruction of government administration, both misdemeanors
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 rays, jets, streams, and filaments.
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. An onboard camera captured a video of the spring popping out of its container as the spacecraft passed over the Pacific Ocean in low-Earth orbit.
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.
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 parts of new planets.
Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn’t as easy. It requires peeling through layers of particle accelerator data to shed light on protons, neutrons and the subatomic processes at play.
