The Super-Massive Black Hole At Our Galaxy's Centre Is Great At Killing Stars

We don’t have to worry about the gigantic black hole at the centre of the Milky Way Galaxy — the scale of its machinations take place over millions of years. There is no doubt however that it is a powerful entity, one NASA recently discovered has the ability to snuff out entire stars with a blast of X-ray “wind”.

A New Type Of Dyson Sphere May Be Nearly Impossible To Detect

Over fifty years ago, physicist Freeman Dyson proposed an awesome, if slightly insane, idea: That an advanced alien civilisation might construct a massive, energy-harvesting sphere around its star, and bunk up inside.

We Is Here! Relive The Last Moon Mission In Its Entirety

If you are fond of the Apollo project, then you’ll love this site Ben Feist has been building for years — which is now online in its very early alpha stage. is a highly addictive, interactive, real-time exploration of the entire Apollo 17 Mission, based upon official NASA footage and the transcription of radio transmissions.

Why The Length Of Saturn's Day Is So Hard To Measure 

The length of a planet’s day seems like such a simple number, a basic piece of information that should accompany any solar system diagram. But probes flying past Saturn have turned up oddly conflicting numbers.

50 Years Ago, NASA Astronauts Smuggled A Sandwich Into Space

On March 23, 1965, astronaut John Young reached into his pocket and offered his crewmate Gus Grissom a corned beef sandwich. It was in the middle of the Gemini 3 mission, and let’s be clear, they were in space. It was a silly little prank but one that, man, really pissed off Congress.

Hubble Gives Us A Wide-Angle View Of An Entire Galaxy

The Hubble telescope is probably best known for its incredible close-up images of everything from star formation to Jupiter’s shrinking spots. But my favourite Hubble pics are always the sweeping, broad views of galaxies — and its latest is a real beauty.

Why This Astronaut Thinks NASA Can Save Humanity From Extinction

Astronaut Daniel T. Barry thinks NASA’s mission to Mars is humanity’s most important endeavour yet, for reasons including the birth of Captain Kirk. We talked to him about what it’s like to explore the Final Frontier.

The Solar Eclipse In 22 Stellar Photos

This morning, a total solar eclipse was visible from the Faeroe Islands and Svalbard, Norway, and a partial solar eclipse from many parts of Europe, Northern Africa and Northern Asia. These stellar photos shows the astronomical event that darkened the skies.

Behold, The Stellar Explosion That Spawned Up To 7000 Earths

Exploding stars are always a sight to behold, but not all supernovae are created equal: Some, for instance, may give birth to thousands of Earth-like worlds.

This Is What Europe's Solar Eclipse Looked Like From Space

This morning Europe was lucky enough to enjoy a solar eclipse — though only those in the Faroe Islands and Svalbard, Norway, were theoretically able to see a full occlusion. This wonderful view from space, though, we can all appreciate.
