Scientists are excited about sending a microphone to Mars for the very first time.
Many images of planets have been manipulated. So have we seen their true colours? Not always, it turns out. But Jupiter's red spot really is red.
Earth is the only planet in our solar system with both plate tectonics and life. Is there a connection?
A look at some of the more obscure methods astronomers use to detect planets around other stars, in the second of a two-part series on finding world's elsewhere in the universe.
Astronomers have discovered more than 3,000 planets around other stars, so far. In the first of a two-part series we look at how they find world's elsewhere in the universe.
Why Planet Nine should be found in the next few years ... if it exists.
We take our understanding of the solar system for granted, but it took centuries to figure out. The original writings of Ptolemy, Copernicus, Galileo and others show how they sparked a revolution.
A US$100-million plan has been announced to send tiny probes out in space in search of life elsewhere in the universe. But are they looking in the right place?
The search for new objects, including new planets, in our solar system has turned up some interesting finds. There have been a few failures over the years too.
A new planet in our solar system? Let's get direct proof before we start naming it.
Scientists say they have evidence that the solar system has an extra planet, bigger than Earth and way beyond Pluto. So how come we never knew this before?
From the high-speed journey to Jupiter to solar eclipses, meteor showers and planetary alignments visible in the skies above -- add these space highlights to your 2016 calendar.
Recent Martian findings are just the latest discoveries of aurora on other planets, both in and out of our solar system.
Space scientists have a busy decade ahead with plans to visit Jupiter, Mars, Mercury and other interplanetary bodies all on the cards.
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
In the long lead-up to our ultimate flyby of Pluto, space science has reconfigured our notions of what it means to be a solar system, a planet, a world.
The New Horizons spacecraft is only hours away from its closest approach to Pluto. It's hoped the brief encounter will help answer many questions about the oddball member of our solar system.
Jupiter's moon Europa is one of the most enticing objects in our solar system, and a future NASA mission may help reveal whether it is a suitable for life.
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
Who gets to name the craters and features on our planets was once an ad hoc affair. But now the public can have a say with just days left to vote.
