There has been much excitement this week about the possibility of water -- and life -- on some newly discovered exoplanets. But we can look closer to home for evidence of ET.
An artist’s concept of what it could look like on the surface of one of the exoplanets of TRAPPIST-1.
Several of the newly-discovered exoplanets orbiting a small star appear to be locked in an intricate dance that hints at how such planetary systems can form.
Artist’s impression of what the view might be like from the surface of the exoplanet TRAPPIST-1f.
If there's life on one of the Earth's seven sisters, chances are it has spread to all of them.
Have we really discovered other “Earth-like” planets orbiting around other stars? Understanding what we do and do not know about exoplanets is the key to answering this question.

Over the last 20 years, advances in the field of exoplanet discovery have excited the imaginations of scientists and enthusiasts alike. But we're in position to know yet whether a planet is habitable.
The discovery of the year was the first detection of gravitational waves.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
Hi Juno, welcome to Jupiter.
From the discovery of gravitational waves, to the Pokémon Go phenomenon to the Census debacle, it's been a big year in science and technology.
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?

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.

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.

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.

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…
