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.

Di Indonesia bagian barat, gerhana bulan dimulai Sabtu dinihari pukul 01.24 WIB dan berakhir pada 05.19 WIB. Terlama sepanjang abad ke-21.
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.
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.
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 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.
The Cassini space probe discovered several new moons on its mission to Saturn, and revealed fresh views of the moons we already knew about.
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?
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…
We’ve just passed another winter solstice. Wednesday June 21 was the shortest day of the year. I live in Melbourne, so we had just 9 hours and 32 minutes of daylight, and it was dark and grey, so we certainly…
Australia’s new partnership with the European Southern Observatory will give our astronomers access to much bigger telescopes.
On Thursday evening, May 4, we’ll get our second chance to see the Moon pass directly in front of the bright star Regulus. From across Australia, the star will appear to blink out of view before emerging…
People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
The ABC is encouraging us all to get out and observe the sky with their exciting Stargazing Live series to air April 4-6 with Professor Brian Cox and involving many astronomers across Australia. Here’s…
A group of astronomers are trying to reclassify Pluto as full ‘planet’. But there are good reasons to leave our classification system alone, and this doesn’t mean Pluto is any less interesting.
Across Australia, on the evening of February 11/12, the Full Moon will travel directly in front of the bright star Regulus. For about an hour, the star will be hidden from view as the Moon passes by. This…
2017 is looking to be a spectacular year for meteor showers. So here’s what to look out for in both the northern and southern skies.
A beautiful full moon will grace our skies on Monday November 14 this year. Full moons always rise around sunset, so look for it towards the east during evening twilight. Every month, occasionally even…
Look west in the evening sky and Venus is almost impossible to miss, shining with a brilliant steady light. In fact, it is so bright it’s often mistaken for a plane. On the evening of Friday October 28…
Last Friday, September 30, the European Space Agency’s (ESA) Rosetta mission, which explored the Comet 67P/Churyumov-Gerasimenko, reached its final conclusion and was heralded a resounding success. The…
Astronomers have found an Earth-like planet orbiting our nearest neighbour, the red dwarf star Proxima Centauri. So any chance that planet may be habitable?
A fantastic lineup of planets has been visible over the past few weeks. Glance upwards just after sunset and all five bright planets – Mercury, Venus, Mars, Jupiter and Saturn – the only planets that can…
The Earth has one steadfast companion – the moon has been locked in orbit around the Earth since its violent formation more than four billion years ago. However, Earth’s gravity can also tug on small nearby…
