A composite image of one night watching the Orionids meteor shower.
A big year ahead for some of the meteor showers this year. Here's your 2020 guide on when and where to look to catch nature's fireworks.
The Moon passes in front of the Sun during this eclipse at Lake Bolac, Victoria, April 29, 2014.
On December 26 a solar eclipse will be visible from northern Australia, southern Asia and parts of the Middle East.
A grassland earless dragon at Jerrabomberra, NSW, November 1991. The search is now on for this species’ Victorian cousin.
The Victorian grassland earless dragon may well be the first lizard species driven to extinction on Australia's mainland. But conservationists aren't ready to declare it dead just yet.
The 2018 Geminids meteor shower recorded over two very cold hours on the slope of Mount Lütispitz, Switzerland.
Moonlight will spoil some of the big meteor showers this year, but still plenty of others to see. So here's your guide on when and where to look to catch nature's fireworks.

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.
The Derwent River Sea Star was only documented for 25 years before its extinction.

It's quite hard to tell when a sea creature is extinct – there's always hope it will turn up somewhere.
An artist’s impression of the path of star S2 as it passes very close to the supermassive black hole at the centre of the Milky Way. The very strong gravitational field causes the colour of the star to shift slightly to the red. (Size and colour exaggerated for clarity.)
Astronomers traced a single star as it passed close to the black hole at the centre of our galaxy, and detected the telltale signature of Einstein’s gravity in action.
Bulan “berdarah” pada 31 Januari 2018. Kesempatan kedua kita untuk melihat gerhana bulan tahun ini akan terjadi pada 28 Juli.
Di Indonesia bagian barat, gerhana bulan dimulai Sabtu dinihari pukul 01.24 WIB dan berakhir pada 05.19 WIB. Terlama sepanjang abad ke-21.
The Blood Moon from January 31, 2018. Our second chance to see an eclipsed Moon this year is coming up on July 28.
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.

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.
Changing colours of the Moon during a total lunar eclipse, Mt Buffalo National Park, June 16, 2011.
There is plenty of excitement about the lunar eclipse this week, but don't believe all you read and hear about this wonderful astronomical event.

Your guide to some of the best meteor showers for 2018. Where to look and when in both the northern and southern skies to catch nature's fireworks.
Sunrise over Brisbane.
A solar day is a measure of how long it takes the Earth to rotate from one noon to the next, and today's summer solstice also happens to be the longest solar day of the year.
The pygmy right whale,
Caperea marginata, at sea.
Fossils of a whale thought to be found only in southern waters have been discovered at two sites in the northern hemisphere.
Cassini makes the first radio occultation of Saturn’s rings producing this simulated image with green for particles smaller than 5cm and purple where particles are larger.
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.
A Cassini portrait of five of Saturn’s moons. 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.

The Cassini space probe discovered several new moons on its mission to Saturn, and revealed fresh views of the moons we already knew about.
An illustration of Cassini diving between Saturn and the planet’s innermost ring.
With only days to go before NASA's Cassini space probe ends its two-decade mission to explore Saturn, what has it revealed about the ringed planet, the second largest in our solar system?
Father and son, together the magnificent gas giants contain 90% of the mass of all objects orbiting the Sun.
Look towards north after sunset and the two gas giant planets, Jupiter and Saturn, can be seen among the stars. Jupiter is named for the Roman king of the gods and its great size allows it to shine with…
The famous “faceless fish”, which garnered worldwide headlines when it was collected by the expedition.
Surveying the bottom of the ocean turns out to be far from easy. But there was something wonderful about seeing animals we have only read about in old books.
