What’s the Difference Between a Rocket and Space Plane? Amazing Hand-Drawn Animations Explain It All

You gotta love Earth’s atmosphere. It basically makes life (as we know it) possible on our planet by providing warmth and air to breathe, as well as protecting us from nasty space things like radiation and smaller asteroids. But for studying space (i.e., astronomy) or coming back to Earth from space, the atmosphere is a […]

When helium behaves like a black hole

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space — is also true for cold helium atoms that can be studied in laboratories. This finding may be a step toward a long-sought quantum theory of gravity and new advances in quantum computing. …

Astronomers hazard a ride in a ‘drifting carousel’ to understand pulsating stars

What sounds like a stomach-turning ride at an amusement park might hold the key to unraveling the mysterious mechanism that causes beams of radio waves to shoot out from pulsars — super-magnetic rotating stars in our galaxy. …

Does Mars have rings? Not right now, but maybe one day

Researchers have developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon. …

Less radiation in inner Van Allen belt than previously believed

The inner Van Allen belt has less radiation than previously believed, according to a recent study. Observations from NASA’s Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation. …
