The core innovation lives in what SpectraEyes calls the Real-Time Dual-Screen Synchronization System. Rather than attempting to merge thermal and night vision into a single confused image, the optics route each feed to its own dedicated 1280×720 LCD screen inside the binocular housing.

We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.

Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.

For most of the twentieth century, airpower was one of the most costly components of military strength. Fighter jets, strategic bombers, and advanced missile systems necessitated massive financial investments, highly skilled personnel, and sophisticated logistical support networks. Only great military forces had the ability to sustain these capabilities.

The momentum enhancement factor for DART's impact was about two, meaning that the debris loss doubled the punch created by the spacecraft alone. The new study shows the impact ejected so much material from the binary system that it also changed the binary's orbital period around the Sun by 0.15 seconds.

The facility, known as Noctis-2, will include an optical array and potentially an infrared telescope. It will provide a "persistent stare capability" of the orbit used by geostationary satellites, broader monitoring of the skies and the ability to examine chosen objects, according to a preliminary market engagement notice published on 16 March.

Apple's satellite features were originally designed for emergencies, allowing iPhone users to contact emergency services when cellular and Wi-Fi coverage is unavailable. With recent versions of iOS, Apple has expanded those capabilities to include sending and receiving messages via satellite. This makes it possible to stay in touch with friends and family from remote locations where traditional networks do not reach, such as hiking trails, rural areas or offshore locations.

On February 28, ships navigating the Strait of Hormuz started appearing on tracking screens in places they couldn't possibly be. They appeared to be sitting on airport runways, parked on Iranian land, and clustered at nuclear power plants. More than 1,100 commercial vessels had their navigation systems scrambled in a single day following US-Israeli airstrikes on Iran, bringing a waterway that handles a fifth of the world's oil exports to a halt.

Wildfire prevention has traditionally relied on blunt tools, such as rigid inspection cycles and emergency power shutoffs. Now a new generation of technology start-ups is pitching a more targeted approach: using artificial intelligence to help utility companies decide what to inspectand where to intervenebefore a spark becomes a blaze. The stakes are rising. In 2025 more than 77,000 wildfires were reported in the U.S.significantly more than the past decade's averageand burned more than five million acres.

To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.

While humans have assembled a lot of weather data, flash floods are too short-lived and localized to be measured comprehensively, the way the temperature or even river flows are monitored over time. That data gap means that deep learning models, which are increasingly capable of forecasting the weather, aren't able to predict flash floods.

Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.

By the end of the year, Northwood, based in El Segundo, California, had shown the ability to build eight of these Portal arrays a month. And in January the company had deployed operational Portal antennas across two continents. These deployments, which comprise an area of 8 to 15 meters, have the equivalent capability of a 7-meter parabolic dish, said Griffin Cleverly, co-founder and chief technical officer of Northwood.

Can quantum physics enable better, cheaper, faster satellite photos? In a month or two, a startup will test a "quantum camera" for space-based imaging. If it works, it could slash the cost of missile defenses and give smaller NATO allies and partners spy-satellite capabilities that were once exclusive to major powers.

Our iron giant is a deep space radio telescope, with an antenna dish measuring forty-six metres across, the largest instrument of its kind in Canada. Starting in the 1960s, the Algonquin Radio Observatory performed a number of cutting-edge scientific projects, including joining SETI's early efforts, in the 1970s and 1980s, to find signatures of alien life-spectrum emissions from water molecules, artificial transmitter signals. No luck.

Earlier this week, the Sun unleashed a powerful X-class solar flare, a major burst of electromagnetically charged particles that lit up the Earth's night sky as they entered our planet's atmosphere. The effect was stunning: a dazzling display of auroras reaching as far as southern California. Forecasters that it was one of the largest solar storms in decades, making for a particularly unique opportunity to watch the show unfold.
