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.

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.

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?
Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy.

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…
Planets orbiting a red dwarf, much like Krypton’s star Rao.
It could be orbiting LHS 2520.
An artist’s illustration of Kappa Ceti whose stellar winds are 50 times stronger than our sun’s. Any Earth-like planet would need a magnetic field to protect its atmosphere if it was to stand a chance of hosting life.
In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.
If you’re looking for life, you’d do well to look for some moons.
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.

The search for new objects, including new planets, in our solar system has turned up some interesting finds. There have been a few failures over the years too.
Artist’s depiction of the newly discovered Jupiter-like planet orbiting the star HD 32963.
Jupiter had a big influence on how our solar system's planets formed. New research – led by a high school student – tried to nail down how rare Jupiter analogs really are in other planetary systems.
Could this ever happen between close planetary neighbours?
New research gives a clue about what happens when there are two habitable worlds in the same solar system.
