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…

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…

Watch a replay of the launch first stage: The SpaceX Falcon 9 rocket roared off the launch pad at 11:35am Canberra time, boosting the robotic Dragon capsule into a three-day chase of…

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…

Weekly Science Picks
It’s been an interesting week for science news, and I’ve been lucky enough to be asked to give this week’s science picks! This made me spend a little while sipping contemplatively on a cup of vanilla iced coffee and wondering where to even start… The articles I’ve selected are, of course, slanted towards my own…

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…

Weekly Science Picks
“La rentrée!” Paris — first week of September. It’s when the city reignites again, everyone comes back from holiday and gets back to work, and — more importantly — kids go back to school. In celebration of “le bon retour” my first pick comes from right here on Australian Science. Kelly Burnes’ musings on the…

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,…

The whole Earth-side of the Moon should be protected forever
Earlier this year, the New York Times had an interesting piece about museums seeking to protect small areas of the Moon around the Apollo landing sites. And a good thing too: “…the next generation of people visiting the moon might carelessly obliterate the site of one of humanity’s greatest accomplishments.” More recently, NASA has released draft guidelines around protecting…

Mysterious Mars
Mars is full of secrets and mysteries. The classic definition of a desert world, our planet’s arid sibling is a parched wilderness of dunes and planetwide dust storms. With a thin carbon dioxide atmosphere and only 38% the gravitational pull of Earth, there are a lot of puzzles about this cold and frosty little planet,…

Radio quiet, please!
Originally conceived over 20 years ago, there’s a project being undertaken by scientists and engineers across the whole world to help us all better understand the mysteries of the galaxy and the very beginnings of the Universe. It’s estimated to be completed by around 2024,costing $1.85 billion AUS (€1.5 billion). Once completed, it’s set to…
