For 57 years, the Arecibo Observatory’s 1,000-foot dish sat sunk into a Puerto Rican valley listening to the sky, and in December 2020, after cables holding its 900-ton instrument platform snapped one by one, the entire structure gave way and crashed straight through the reflector below.

For 57 years, the Arecibo Observatory’s 1,000-foot dish sat sunk into a Puerto Rican valley listening to the sky, and in December 2020, after cables holding its 900-ton instrument platform snapped one by one, the entire structure gave way and crashed straight through the reflector below.

Ángel Vázquez, director of telescope operations at the observatory, was standing outside the control room on the morning of December 1, 2020 when he heard a loud bang. He looked up in time to see the rest happen. A 900-ton instrument platform, suspended 500 feet above the dish on a handful of steel cables, broke … Read more

Introducing: The New Space-Tested SC02C, a Mechanical Chronograph by Konstantin Chaykin

Mechanical watches have accompanied astronauts and cosmonauts into space for decades, but few contemporary watches can claim to have been developed specifically around the demands of extravehicular activity, like Konstantin Chaykin’s new SC02C. Born from the manufacturer’s collaboration with Roscosmos, the Russian space agency, the chronograph has been tested during four spacewalks and is now … Read more

An 18-year-old high school senior from Pasadena wrote machine-learning code to comb 200 billion entries of raw infrared sky data, sorted what came back, and in 2025 found 1.5 million new potential objects

An 18-year-old high school senior from Pasadena wrote machine-learning code to comb 200 billion entries of raw infrared sky data, sorted what came back, and in 2025 found 1.5 million new potential objects

Let’s start with the figure that makes the rest of the story difficult to imagine: 200 billion. That’s about the number of rows of data a machine learning program created by a Pasadena high school student had to process. Each row is a moment when a retired NASA telescope captured a flash of infrared light … Read more

A Billion Tons of Ice Are Hiding Under Utah, Study Finds : ScienceAlert

A Billion Tons of Ice Are Hiding Under Utah, Study Finds : ScienceAlert

When we imagine glaciers, it’s easy to imagine vast expanses of white ice glistening under the sky. But not all glaciers take that shape. The world is covered by a different type, called rock glaciers: landforms in mountainous regions where masses of ice and rock coexist, hidden beneath a hard surface of rock and boulders. … Read more

‘There is no conflict between quantum physics and gravity’: Physicists prove Einstein’s equivalence principle holds true at quantum scales

'There is no conflict between quantum physics and gravity': Physicists prove Einstein's equivalence principle holds true at quantum scales

For the first time, physicists have measured the small quantum shift that an object acquires as it falls through Earth’s gravity, an effect of Einstein’s relativity that was predicted nearly a century ago but never observed. The researchers placed ultracold rubidium atoms in a superposition, a quantum state in which a single particle takes two … Read more

‘It was very surreal,’ UNC Asheville researchers make a discovery in drug-resistant staph

ASHEVILLE, N.C. (WLOS) — What began as an undergraduate research project at the University of North Carolina at Asheville resulted in a discovery that earned the team recognition in an accredited peer-reviewed journal. ‘It was very surreal’: UNC Asheville researchers make discovery in drug-resistant staph. (WLOS) The team discovered a weakness in a protein that … Read more

Scientists Bent Graphene Almost as Sharply as Atoms Allow and Something Strange Happened

Scientists Bent Graphene Almost as Sharply as Atoms Allow and Something Strange Happened

In 2008, two physicists proposed that something strange should happen when graphene bends almost as much as the atoms allow. They argued that the curvature could unbalance the electrons, producing electrical polarization solely from the shape. If they were right, that meant that a wonder material (graphene has amazing strength, conductivity, flexibility and lightness) could … Read more

The Pixel Watch-exclusive weather app is getting a handy upgrade

Rita El Khoury / Android AuthorityAdd Android Authority on Google: TL;DR A new update to Pixel Weather for Wear OS introduces three new complications. Pixel Watch owners can now add air quality, pollen, and precipitation index complications to their watch face. Some third-party Wear OS weather apps already offer some of these complications for Pixel … Read more

The BepiColombo mission draws closer to Mercury

CAPE CANAVERAL, Fla. (AP) — Two Mercury-bound spacecraft left their mothership behind Thursday and headed for the home stretch of their nearly decade-long journey to the solar system’s smallest and closest planet to the Sun. The linked European and Japanese spacecraft separated as planned from their cruise, but controllers had to wait an anxious two … Read more
