Is There Potential for Life on Europa? We Asked a NASA Expert: Episode 52

That’s a great question. And it’s a question that NASA will seek to answer with the Europa Clipper spacecraft. Europa is a moon of Jupiter. It’s about the same size as Earth’s Moon, but its surface looks very different. The surface of Europa is covered with a layer of ice, and below that ice, we […]

NASA: New Study on Why Mars is Red Supports Potentially Habitable Past

A new international study partially funded by NASA on how Mars got its iconic red color adds to evidence that Mars had a cool but wet and potentially habitable climate in its ancient past. The current atmosphere of Mars is too cold and thin to support liquid water, an essential ingredient for life, on its […]

How Long Does it Take to Get to the Moon… Mars… Jupiter? We Asked a NASA Expert: Episode 51

So how long does it take to get from Earth to the Moon, to Mars or to Jupiter? As with most things in life, the answer is: it depends.

What You Need To Know About the March 2025 Total Lunar Eclipse

The Moon will pass into Earth’s shadow and appear to turn red on the night of March 13 or early in the morning on March 14, depending on time zone. Here’s what you need to know about the total lunar eclipse. What is a lunar eclipse? A lunar eclipse occurs when the Sun, Earth, and Moon align […]

NASA Juno Mission Spots Most Powerful Volcanic Activity on Io to Date

Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme. Scientists with NASA’s Juno mission have discovered a volcanic hot spot in the southern hemisphere of Jupiter’s moon Io. The hot spot is not only larger than Earth’s Lake Superior, but […]

NASA’s Webb Reveals Smallest Asteroids Yet Found in Main Asteroid Belt

NASA’s powerful James Webb Space Telescope includes asteroids on its list of objects studied and secrets revealed.  A team led by researchers at the Massachusetts Institute of Technology (MIT) in Cambridge repurposed Webb’s observations of a distant star to reveal a population of small asteroids — smaller than astronomers had ever detected orbiting

NASA Researchers Discover More Dark Comets

These celestial objects look like asteroids but act like comets now come in two flavors. The first dark comet — a celestial object that looks like an asteroid but moves through space like a comet — was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce […]
