Sending man to the moon and back is one of humanity's greatest achievements. Sadly, despite massive advances in space technology, this feat has't been repeated since the Apollo 17 mission more than 45 years ago. Today I discovered why not.

NASA want to find themselves some new planets and with ol' faithful Kepler on its last legs, they're sending the Transiting Exoplanet Survey Satellite (TESS) up into the great dark on the back of one of Elon Musk's SpaceX Falcon 9 rockets. This is the first mission to do so, so it's a big deal!

Flat Earthers, in addition to believing the world is flat, also believe that every single image of earth taken from space has been photoshopped. And honest to Christ, looking at this new photo of Saturn, I'm starting to wonder myself.

Last night, NASA's multi-billion dollar Cassini–Huygens spacecraft crashed into Saturn. It was a spectacular end to a 20-year mission that has provided invaluable information abut the ringed planet and its moons. Here's what you need to know, along with a stream to the live event.

There's a total solar eclipse happening on August 21, 2017. Unfortunately, the Moon's unabashed Sun-blocking power will only be visible from the continental US and will only be visible in other countries as a partial eclipse. Fortunately, these streams mean you can enjoy the full extent of this celestial event from Australia.

Eating bread in space is a surprisingly dangerous undertaking: the free-floating crumbs could cause someone to choke, lodge themselves in someone's eye, or worst of all, cause a fire if it gets into the electrical panel. That's why most astronauts have to eat the less appealing alternative -- the tortilla.

NASA's Armstrong Flight Research Center is currently in the process of uploading hundreds of extremely rare films to YouTube. And I'd advise you to stop reading if you want to get anything done tonight.

If you're on the US East Coast and see some odd-coloured clouds in the sky today, it's probably science's fault.

NASA has just released it's 2017-2018 software catalogue, which includes hundreds of free, royalty-free applications for a wide variety of uses.

Seven planets orbiting a single star have been discovered 40 light years away from Earth. According to NASA, all of them could support the presence of liquid water (and possibly living organisms). Read on to find out more.

In a few hours, NASA will reveal a new discovery it has made "beyond our solar system" relating to a certain exoplanet. For space buffs, this is pretty exciting stuff. Click here to watch NASA's news announcement live.

NASA has launched its popular space exploration app for all you couch cosmonauts out there who own an Apple TV. The free app has everything from high-res images of space to videos on-demand, and provides a live stream of NASA TV.

NASA is preparing to cause a "large fire" inside a Cygnus resupply vessel to test the affects of fire inside a spaceship in microgravity. Here's how and when to watch this volatile event live in Australia.

In a little under an hour, US astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko will attempt to land the Soyuz TMA-18M spacecraft after 11 months in orbit. This basically involves steering a fiery metal can from 400km in the sky towards Earth at speeds of 27,360km per hour. You can watch NASA's livestream in Australia right here. We've also highlighted the estimated times for key events during the landing.

There are a number of names that most people associate with the momentous 1969 Moon landing -- Neil Armstrong, Buzz Aldrin, even Stanley Kubrick for dedicated conspiracy theorists -- but Margaret Hamilton is not usually among them. Yet this pioneering woman was the lead developer for Apollo's flight software in the days when working mothers were rare -- let alone female computer scientists.

How do you go about hunting for life on another planet elsewhere in our galaxy? A useful starting point is to imagine looking from afar for signs of life on Earth. In a telescope like those we have on Earth, those aliens would likely just see the Earth and sun merged together into a single pale yellow dot.
