After 49 Years in Deep Space, Voyager 1 Goes Quiet on One More Front
Somewhere past the edge of our solar system, a spacecraft the size of a small car hurtles through interstellar space at more than 51,000 miles per hour. Built in an era before personal computers, assembled by hand, and launched before most people alive today were born, Voyager 1 has kept going longer than almost anyone…
Scientists Discover Darkness Moves Faster Than Light
For decades, one idea has stood unchallenged in popular science: nothing travels faster than the speed of light. It is a statement repeated in classrooms, documentaries, and everyday conversations as a kind of universal truth. The number itself, 299,792,458 meters per second, has come to represent a boundary that nature simply does not cross. But…
What Artemis astronauts might experience after just 10 days in space
The journey to the Moon is often presented as one of humanity’s greatest achievements, something that blends cutting-edge technology with an almost dreamlike sense of exploration. But as the Artemis II crew prepare to return to Earth after more than a week in space, the focus begins to shift away from the mission itself and…
How a 27-Year-Old Rewrote the Story of the Universe Section
Adam Riess helped build one of the most important scientific theories of the last century. His measurements changed how physicists understand the cosmos, earned him a Nobel Prize in Physics, and shaped the story humanity tells itself about how everything ends. Now he wants to tear that story apart. At 55, Riess sits in his…
NASA’s Voyager Spacecraft Discovered a ‘Wall of Fire’ at the Edge of Our Solar System
In 1977, NASA launched two spacecraft on a mission that would outlast every prediction. Voyager 1 and Voyager 2 left Earth to study the outer planets, but their journey never stopped. Decades later, Voyager 1 had traveled farther than any human-made object in history, drifting through regions of space no instrument had ever sampled. And…
New Study Shows Chickpeas Can Grow In Moon Soil Like Conditions
Humanity has spent decades imagining what life beyond Earth might look like. Space agencies have designed rockets capable of traveling farther than ever before, engineers have developed habitats that could support astronauts in extreme environments, and scientists continue to explore how humans might one day live on the Moon or even Mars. Yet one basic…
Astronomers Say Asteroid 2024 YR4 Could Trigger the Most Energetic Lunar Impact Ever Recorded
Astronomers are rarely given the luxury of time when it comes to cosmic events. Most asteroid impacts happen without warning, either burning up in Earth’s atmosphere or striking distant worlds long before humans had the tools to notice. That is why Asteroid 2024 YR4 has generated such intense scientific interest. It is not because the…
Why Space Is Freezing Cold Even Though the Sun Is Incredibly Hot
Look up at the Sun on a clear day and it feels almost impossible to believe that anything touched by its light could be cold. The Sun burns at millions of degrees at its core and pours staggering amounts of energy into the solar system every second. That energy crosses millions of kilometers of space…
Why the Universe Has Not Introduced Us to Aliens
For more than half a century, humanity has stared into the night sky with a single, unsettling question echoing through science, philosophy, and imagination alike. If the universe is so vast, so old, and so full of stars, why does it appear so quiet? Every new telescope, every upgraded radio array, and every planetary discovery…
Radio Waves Meant for Submarines Created an Invisible Shield in Space
Humanity has a habit of changing the planet in ways no one expects. We see it in rising sea levels and vanishing glaciers. We saw it when the DART mission knocked an asteroid off course, proving our species could move celestial bodies. Yet some of our most profound impacts happen without any intention at all,…
