Capturing the shadow of Saturn’s moon Titan from right here on Earth

Titan is more than a billion kilometres from our Sun but occasionally it's shadow can be seen here on Earth, with the right technology. That's what scientists gathered in Western Australia to observe.

The latest from Juno as Jupiter appears bright in the night sky

Now's a great time to see Jupiter as it's about to be the closest to Earth for some time. Time too to catch up with the latest on the Juno mission, exploring the largest planet in our Solar System.

We’ve found an exo-planet with an extraordinarily eccentric orbit

A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.
It’s a bird… It’s a plane… No, it’s an object from another solar system! Astronomers have been scrambling to identify a mysterious object passing through our solar system at a speed of about 160,000 km/h. This NASA file image shows a simulation of asteroids passing the earth. (Handout)

How scientists discovered our first interstellar mystery visitor

Astronomers have detected what is believed to be the first interstellar object ever seen passing through our solar system.

The beauty and mystery of Saturn’s rings revealed by the Cassini mission

The Cassini space probe took us up close and through the beautiful rings of Saturn. It captured some amazing images, and even the sound of the rings during its mission.

Janus (179km across) is on the far left, Pandora (81km across) orbits between the A ring and the thin F ring, Enceladus (504km across) is centre, Rhea (1,528km), is bisected by the right edge of the image and the smaller moon Mimas (396km) is seen beyond Rhea also on the right side of the image.

What Cassini’s mission revealed about Saturn’s known and newly discovered moons

The Cassini space probe discovered several new moons on its mission to Saturn, and revealed fresh views of the moons we already knew about.

The PLATO mission: an investigation of planetary systems

While we on Earth are familiar with our own star, the Sun, the European Space Agency's PLATO mission will explore solar systems similar to ours as well as those that are more exotic.
