Astronauts Splash down on Earth after a Space Station Medical Evacuation

Satellites Tech, Space & Environment /

Four astronauts evacuated from the International Space Station (ISS) safely returned to Earth after a “serious” medical issue cut their mission short by a month. The crew’s captain, NASA astronaut Mike Fincke, was the first to leave the spacecraft, smiling and wobbling slightly before lying on a gurney as part of standard procedures. NASA’s Zena […]

Rainbow Around Nearby Dead Star Puzzles Scientists

Aerospace, Space & Environment /

A small piece of a dead star, located just 731 light-years away, has left astronomers puzzled with a dazzling phenomenon: a bright, glowing bow shock. While such a feature might not be unusual in other cases, the white dwarf RXJ0528+2838 shows no apparent mechanism to explain the colorful nebula encircling it. Quiet Star Shocks Astronomers

First Wobbling Black Hole Jet Found in a Disk Galaxy

Aerospace, Space & Environment /

Using the W. M. Keck Observatory astronomers in Hawaiʻi discovered the largest stream of superheated gas from a nearby galaxy, showing a supermassive black hole can affect its galaxy far beyond the core. The discovery highlights galaxy VV 340a, where massive gas streams extend up to 20,000 light-years—farther than ever recorded. The study, led by

NASA Enables Mars Rover to Navigate on Its Own

Aerospace, Space & Environment /

Think self-driving cars are impressive? Imagine a rover navigating a planet more than 100 million miles away. On Wednesday, NASA revealed that its Mars Perseverance rover had achieved an extraordinary display of endurance and autonomy. Over the span of four hours and 24 minutes, the rover traveled 1,350.7 feet—roughly a quarter mile—the longest distance any

Battery Charging Fuels Lithium Recycling Breakthrough

Reusability, Space & Environment /

Lithium may not be the fictional “Spice” from Dune, but this shiny, highly reactive metal is just as crucial in the real world. Its exceptional ability to store electricity makes it indispensable for moving away from fossil fuels and toward a cleaner, low-carbon economy powered by renewable energy. Today, about 87% of global lithium is

Researchers Determine How Much Faster Time Moves on Mars

Planetary Science, Space & Environment /

A study by two physicists at the U.S. National Institute of Standards and Technology (NIST) found that, on average, clocks on Mars run about 477 microseconds faster per day than those on Earth. Although this time difference remains extremely small, it can significantly impact efforts to synchronize clocks precisely between Earth, the Moon, and Mars.
