From Earth spinning on its axis and orbiting the Sun to it precessing like a top, lots of factors affect which stars you can see in the sky.
Which way is ‘down’ has a different answer depending on where you are on Earth, in the solar system, in our galaxy and beyond.
Mars may have been hospitable to life early in its history.
Or perhaps there was no star at all.
The only Australian hardware on board the legendary telescope is starting to fulfil its duties.
In the 30 years since the discovery of 51 Pegasi b, more than 6,000 planets outside our Solar System have been catalogued. Two modern-day explorers explain how.
The largest telescope in space has been trained on a rocky exoplanet.
Could tiny stars a fraction the size of our solar system’s Sun have habitable planets orbiting them? A new study says it’s possible.
Mars isn’t a bright, fire-engine red, but the iron oxide in its rocks makes it appear redder than other planets, especially from afar.
The biggest planets hogged a lot of the raw materials and were fully formed first.
As the night sky became polluted with light from electrified cities, people built planetariums. Today, they’re more impressive than ever.
The Earth started as a mixture of gas and dust around the Sun and grew as it collided with asteroids and dust particles.
The exoplanet K2-18b could harbor a massive ocean, but scientists will need to study the planet more to see if it’s really likely to host life.
The number of known moons in our Solar System has been rising for centuries, but astronomers say it has probably peaked – for now.
A full moon, low on the horizon, tinted red – it’s a sight not to be missed.
At the very beginning of its history, Earth was dry. How did it become a blue planet? A new theory could provide an answer.
According to astronomers, there are approximately 200 billion trillion stars in our observable universe — chances are, there’s life out there somewhere.
In 2025 we will see Saturn’s rings ‘disappear’, the Moon turning red, meteor showers and more.
Astronomers have detected possible signs of gases released by volcanic activity.
