On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun. NASA/SDO, AIA

Why we need to get back to Venus

This hot, acidic neighbor with its surface veiled in thick clouds hasn’t benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.

Curious Kids: does the Sun spin as well as the planets?

Yes, the Sun absolutely spins. In fact, everything in the universe spins. Some things spin faster than the Sun, some are slower and some things spin ‘backwards’.

How we found a white dwarf – a stellar corpse – by accident

Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.

Curious Kids: Are there living things on different galaxies?

There are probably more than a million planets in the universe for every single grain of sand on Earth. That’s a lot of planets. My guess is that there probably is life elsewhere in the Universe.

Curious Kids: Is there anything hotter than the Sun?

There are lots of places where it’s much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.

A Goblin could guide us to a mystery planet thought to exist in the Solar system

Whether you call it Planet X or Planet Nine, talk of another planet lurking in our Solar system won’t go away. So what does the discovery of a new object – nicknamed “The Goblin” – add to the debate?

Five in a row - the planets align in the night sky

The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.

I’ve Always Wondered: How do we know what lies at the heart of Pluto?

Pluto has a density between that of rock and ice – so that immediately suggests the dwarf planet is made of a mix of both. But how do we know?

Curious Kids: Where are all the other galaxies hidden?

We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.

It’s a busy night sky this July, so make sure you look up

All five five planets visible to the naked-eye are on show in the night skies over Australia, and a Blood Moon on the way too.

Goodbye Kepler, hello TESS: Passing the baton in the search for distant planets

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.
