Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
The now defunct Infrared Astronomical Telescope was one of the satellites involved in the near-collision.
Two defunct satellites passed within metres of one another, prompting renewed focus on the dangers of space debris. But with many satellites treated as military secrets, how do we track the hazards?
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.

Three hours north-east of Parkes lies a remote astronomical research facility, unpolluted by city lights, where researchers are trying to unlock some of the biggest questions about our Universe.
Finally dragged out of the shadows.

The Swift Observatory passed a milestone: 1 million snapshots of the universe. These exquisite and revealing pictures have captured the births and deaths of stars, gravitational waves and comets.

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 number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people's imagination?

Astronomers were looking forward to the first high-res X-ray spectra from space, and all they would tell us about the cosmos. But unknown disaster seems to have befallen the Japanese satellite.
An artist’s impression of the ASTRO-H telescope.
The universe looks very different with X-ray vision, revealing some of the most energetic interactions in our galaxy. Japan's new Hitomi telescope will help us see these wonders.
Bigger but not better than Hubble. The James Webb’s primary mirror.
It's urgent that we turn our attention to a high definition space telescope that will allow us to directly image exoplanets.
Bye, Earth telescopes! You will never reach my level.
Ground-based telescopes are getting bigger and better while still being cheaper than space telescopes. But the vital scientific contributions made by Hubble demonstrates why we need both.
