Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
Out there in space there is no air.

Out there in space there is no air. If you took your helmet off, all the air you need to breathe would whoosh out.
TESS will soon be our eye in the sky.

When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase as Kepler retires.
The ISS sees us on Earth, but look up at night and you may see it, too.
A couple thousand satellites are orbiting Earth right now. Under the right conditions, your naked eye can spot these human-made objects in the night sky.
China’s Tiangong-1 space station is due to hit Earth, and Australia is in the crash landing zone.
Cindy Zhi/The Conversation
China's Tiangong-1 space station is hurtling around Earth out of control and about to come crashing down. It's just one of thousands of pieces of space junk left orbiting our planet.
Falcon Heavy’s first payload will be a Tesla Roadster, set to become the world’s fastest car following its launch into a heliocentric orbit.
SpaceX's Falcon Heavy could propel two fully loaded city buses more than 50 times the height of Mount Everest at 32 times the cruising speed of a Boeing 747.
time of moonrise and moonset and the shape of the Moon change throughout the month.

When and where you see the Moon in the daytime depends on what phase it is in.
Rocket Lab successfully launched its Electron rocket from the company’s complex on the Māhia Peninsula in New Zealand.
There are plenty of astronomical things to watch out for this year beyond this week's lunar eclipse, including new Moon landings and a space station falling back to Earth.
As long as clouds don’t get in the way, the view should be spectacular.
A bunch of uncommon things all happening at the same time mean this full moon will have some special attributes.
The comet 67P/Churyumov-Gerasimenko, seen up close.
Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.
A statue of Konstantin Tsiolkovsky in Moscow, Russia.
In the early 20th century a Russian scientist – regarded as the father of rocketry – made some novel predictions on where we would be in space in the 21st century. So how accurate was he?

Scientists looking for signs of alien life from the mystery object passing through our Solar system say they've found nothing "so far".
Twinkle, twinkle, little star…
The precious metal is literally extra-terrestrial, produced in the heart of the stars. How and under what conditions? Scientists know more thanks to a double astrophysical observation.
The first piece of the International Space Station was launched in 1998.
The students of class 3F at Ferny Grove State School want to know how they get oxygen into the International Space Station.
A new trajectory means the mission to uncover core facts about the asteroid belt will happen sooner than planned.
We’ve only travelled into space in the last century, but humanity’s desire to reach the moon is far from recent.
Three new reports examine Australia’s existing space capabilities, set them in the light of international developments, and identify growth areas and models for Australia to pursue.
Space is becoming cheaper, more attractive to investors and increasingly important in our data-rich economy. It's time Australia mapped a path forward.
Nothing to stop high energy weapons being deployed in orbit around Earth.
Australia is playing a major role in developing legal guidelines that would govern how any war in space is played out. The authors of MILAMOS hope the manual is never actually required.
