A coronagraph captured this sublime image of the Moon crossing the Sun’s path. Studying the Sun is crucial for monitoring space weather, as events like coronal mass ejections (CMEs) can disrupt satellites, power grids, and GPS navigation. And yet this scientific research can create beautiful art. Recently, the National Oceanic and Atmospheric Administration (NOAA) captured something magnificent on one of …

There are more than 12,000 active satellites circling Earth at the moment, a growing figure that has nearly doubled in less than three years. This recent boom in the satellite industry has been a major headache for astronomers, with bright satellites appearing as streaks in telescope images of the universe and tarnishing views of the night skies. A new paper …

To study the sun, scientists use a specialized telescope called a coronagraph. This instrument mimics a solar eclipse by using a occulting disk to block out the sun’s bright light. By doing this, astronomers can study the fainter solar atmosphere, the sun’s corona, that’s hard to see when viewing the entire sun. However, recently, a coronagraph used by the National …

SpaceX launched a new Earth-observation satellite along with several smaller spacecraft from California on Tuesday (Aug. 26). A Falcon 9 rocket carrying Luxembourg’s National Advanced Optical System (NAOS) spacecraft lifted off on Tuesday at 2:53 p.m. EDT (1853 GMT or 11:53 a.m. PDT local) from Space Launch Complex 4 East at Vandenberg Space Force Base. In addition to NAOS, which …

“The ultimate test of climate projections is to compare them with what has played out…” says earth sciences professor Torbjörn Törnqvist, lead author on a new study published in the open-access journal Earth’s Future (published by the American Geophysical Union). But after “decades of observations,” he says his researchers “were quite amazed how good those early projections were, especially when …

Satellite data, as revealed in a 2025 study published in Earth’s Future, confirms that sea levels are rising faster than expected, validating decades-old climate projections. Since the 1990s, satellites have provided precise measurements, showing an accelerating rise that underscores the growing risks for coastal areas. This data supports early climate models, proving that our understanding of sea-level rise was more …

The Pixel 10 series might’ve been unveiled two days ago, but we’re still learning about some of Google’s latest features. Today’s announcement comes hand-in-hand with WhatsApp, as the two companies are bringing voice and video calls over satellite as an initial exclusive. The Made By Google account on Twitter was the first to announce the news, followed quickly by a …

In a high-resolution satellite image taken by NASA’s Landsat 8 on May 3, 2016, a series of dark, swirling shapes appeared in the clouds above Heard Island, a remote volcanic island in the Southern Ocean. Located roughly 1,000 kilometers north of Antarctica, this uninhabited landmass became the center of attention after the release of the image revealed what looked like …

Yesterday during its big launch event Google unveiled the Pixel Watch 4 alongside the Pixel 10, Pixel 10 Pro, Pixel 10 Pro XL, and Pixel 10 Pro Fold. The watch is powered by Qualcomm’s newly announced Snapdragon W5 Gen 2 chipset, and one of the perks of this chip is its support for Narrowband Non-Terrestrial Network, aka satellite connectivity. So …
