Giant Impact: making the moon
It began… where it always begins — out there — in the vastness of space. What would it look like, that void of empty nothingness? So early on in the sound of creation, indescribable things all around. Not yet planets, not yet moons. Not yet defined. A titanic mass of rock. Different. Ugly and melancholic.…

The nearest solar system to ours has an Earth-sized planet…
Already there’s an artist’s impression of the newly discovered ‘Alpha Centauri B a’ Yes—you read right. Alpha Centauri has a planet, and it is roughly the size of Earth. And at just 4.37 light years distance, it is theoretically reachable (with a whole lot of space travel development!) despite the frustrating limitations put on us…

Citizen Scientists Discover Four-Star Planet with NASA Kepler
The discovery of planets continues to expand beyond the domain of professional astronomers. A joint effort of amateur astronomers and scientists has led to the first reported case of a planet orbiting a double-star that, in turn, is orbited by a second distant pair of stars. Aided by volunteer citizen scientists using the Planethunters.org website,…

What an Astronaut’s Camera Sees from ISS
When astronauts head to the International Space Station (ISS), Dr. Justin Wilkinson, the chief geoscientist at NASA, asks them to snap pictures of various geographical locations. From this vantage point 250 miles above the planet’s surface, he learns many things — for example, he tells Slate, “there are a lot more examples of a geographical phenomenon called an inland delta…

Hubble goes to the eXtreme to assemble the deepest ever view of the Universe
Like photographers assembling a portfolio of their best shots, astronomers have assembled a new, improved portrait of our deepest-ever view of the Universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining ten years of NASA/ESA Hubble Space Telescope observations taken of a patch of sky within the original Hubble Ultra…

A long time ago in a galaxy far, far away
Feast your eyes on this image… The tiny object in that inset may not look like much. A blurry smudge of red pixels. Not nearly as dramatic as the stunning bouquet of galaxies all around it. But in astronomy, not everything is quite so straightforward. That small red smudge is probably the most exciting thing…

Science or fringe science? Removing the ‘giggle factor’ from Near Earth Object impacts
On June 30, 7.17am in a remote, sparsely inhabited area in Siberia, Russia, near the Podkamennaya Tunguska River, occurred an event of enormous devastation. An asteroid or comet estimated to be 40-50 meters in diameter, exploded at low altitude with an energy almost 200 times that of the atom bomb dropped on Hiroshima. Trees where…

Alien encounters and the man from Grenada
The month of August indeed belonged to the tiny rover that could — Curiosity. We were all hooked right from the landing and until those first images of the red planet were beamed back. Not even Will.i.am could spoil it for us. We revelled in everything in between, from the missed high-fives, peanuts, Neil deGrasse Tyson’s conversation with the rover,…

Kepler Astronomers Find First Planetary System Around a Binary Star
NASA’s Kepler mission has found the first multi-planet solar system orbiting a binary star, characterized in large part by University of Texas at Austin astronomers using two telescopes at the university’s McDonald Observatory in West Texas. The finding, which proves that whole planetary systems can form in a disk around a binary star, is published…

Neil Armstrong’s speech in Sydney 24 August 2011
UPDATE: Regrettably, the CPA engaged lawyers to threaten me with everything they could think of if I didn’t pull the recording (below). So pull it I have. Please feel free to pass on any feelings about this to them. At least for the time it was available, about 500 people got to hear the great man’s words. All…
