Today we hear about some of the fascinating space research underway at Siding Spring Observatory – and how, despite gruelling hours and endless paperwork, astronomers retain their sense of wonder for the night sky.
‘The size, the grandeur, the peacefulness of being in the dark’: what it’s like to study space at Siding Spring Observatory.

Mysterious cosmic flashes known as gamma-ray bursts are caused by the death throes of massive stars.
Two lenses might be better than one.
There's really no reason you can't use binoculars to look into space – and in fact astronomers have been working on doing so for a long time.

For the first time scientists have located the home galaxy of a one-off fast radio burst. Here's how they did it – and what they learned about the galaxy.
Planets form from a disc of dust orbiting a star.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.

The first 60 satellites from Elon Musk's planned low orbit internet network have lit up the skies. But with more planned, astronomers say the satellites could ruin their work.

When you look up at the vastness of space you can see hundreds, thousands and even millions of years into the past.
Enjoying the planets lined up in a row.
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.

About 5 percent of all UFO sightings cannot be easily explained by weather or human technology. A physicist argues that there's compelling evidence to justify serious scientific study and that the skeptics should step aside – for the sake of humanity.
The things you can do with an amaterur telescope.
With a little bit of knowledge and a few pieces of equipment you too can look at the night sky and see it as a cosmologist does.

Astronomers have indirectly spotted some of the first stars in the universe by making their most distant detection of oxygen in a galaxy that existed just 500m years after the Big Bang.
An artist’s illustration of a black hole “eating” a star.
Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
TESS will soon be our eye in the sky.

How long before we find a planet just like our own?

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.
The Small Magellanic Cloud galaxy here seen in infrared light, but it looks different when viewed at other wavelengths.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.
An image by MeerKAT shows hydrogen gas in M83, a famous spiral galaxy.
A precursor to the Square Kilometre Array- the MeerKAT telescope - is being built right now and remarkable progress has been made in the last 12 months.
Map of all matter – most of which is invisible dark matter – between Earth and the edge of the observable universe.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.

Until the recent observation of merging neutron stars, how the heaviest elements come to be was a mystery. But their fingerprints are all over this cosmic collision.

A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of 'multi-messenger' observations.
