Truth is out there.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
All about the atmosphere.
Atmospheric changes on exoplanets could hold clues to our own environmental problems.
The idea that there’s a moral imperative for humans to expand beyond Earth is echoed by influential proponents of space exploration.
Technology had enabled humans to explore the deep sea, the Earth's poles, and outer space. But we shouldn't forget historical lessons about frontiers in the process of traversing them.
An artist’s impression shows the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to our solar system.
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?
Artist’s impression of the surface of the planet Proxima b, orbiting Proxima Centauri.
Scientists have finally found an Earth-like planet we may actually be able to visit.
The ruddy hue of our moon in a total lunar eclipse.
The red hue of the moon during a total lunar eclipse gives astronomers at cue on how to find out more about the planets being discovered around other stars.
An artist’s impression of the polar orbit of WASP-79b.
More than three thousand planets have been found orbiting other stars in our galaxy. The challenge now is to find out more about these planets.
An artist’s impression of Juno above Jupiter’s pole.
Juno’s visit to Jupiter promises to pick up on many of the unsolved mysteries that still remain in understanding of the Jovian system.
Some of the Earth’s fault lines between tectonic plates in the East Asia region.
Earth is the only planet in our solar system with both plate tectonics and life. Is there a connection?
An artists’s impression of how common planets are around the stars in the Milky Way.
A look at some of the more obscure methods astronomers use to detect planets around other stars, in the second of a two-part series on finding world's elsewhere in the universe.
In the Exoplanet Era, we are learning that planets abound in the cosmos.
Astronomers have discovered more than 3,000 planets around other stars, so far. In the first of a two-part series we look at how they find world's elsewhere in the universe.
Artist’s rendition of one of the billions of rocky exoplanets in our galaxy.
Did life once exist on its surface?
Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.
An artist’s impression of a transiting Jupiter-mass exoplanet around a star slightly more massive than the sun.
Many of the new planets found in other star systems have some extraordinary orbital behavior. So what's going on?
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core.
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…
An artist’s concept of select planetary discoveries made to date by NASA’s Kepler space telescope.
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?
kepler all planets may.
The increasingly rapid pace of exoplanet discoveries must mean it is only a matter of time until astronomers find another Earth.
Imagined view from the surface of one of the newly discovered planets, with ultracool dwarf star TRAPPIST-1 in the background.
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.
A laser could hide – or broadcast – our existence.
European Southern Observatory
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.
The plan to use lasers to send mini-spaceships to the stars.
It's an ambitious plan to send a micro-spaceship to our stellar neighbour but is this possible with today's technology or even technology in the near future?
Alpha Centauri is actually the outer star (bottom right) of The Pointers, which point to the Southern Cross.

A US$100-million plan has been announced to send tiny probes out in space in search of life elsewhere in the universe. But are they looking in the right place?
