Space research never stops and it seems neither do the surprises. On ABC Breakfast News I covered some huge results from the last few weeks. Be still my beating (magnetic) heart Earth’s magnetic field…
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?
We don’t need to look for Earth-like planets exclusively around Sun-like stars. Tiny, dim TRAPPIST-1 has only 11 percent the diameter of the Sun and is much redder.
Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
There are technological ways to hide a planet from intergalactic detection – as well as ways to signal that we’re just sitting here, eager for contact.
Aboriginal people have been using the stars to help remember routes between distant locations, and these routes are still alive in our highway networks today.
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.
Each fortnight I get the amazing opportunity to speak about my top stories in space on ABC Breakfast News TV but for those of you who hate early mornings I wanted to make sure you got to hear of these…
After last summer’s Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here’s some of what scientists have learned so far from that rich, slow cache.
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.
As the list of known planets beyond our solar system grows, the search for their moons is intensifying. One reason: they might hold the key to finding life elsewhere in the universe.
