Say hello to the Earth’s nearest exoplanet neighbour: Proxima Centauri b

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?

Explainer: How to find an exoplanet (part 2)

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. ESO/M. Kornmesser

Explainer: How to find an exoplanet (part 1)

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.

RIP E.T. – alien life on most exoplanets dies young

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.
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core. ESA/ATG Medialab

Earth’s magnetic heartbeat, a thinner past and new alien worlds

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…
Alpha Centauri is actually the outer star (bottom right) of The Pointers, which point to the Southern Cross. Y. Beletsky (LCO)/ESO

Is Alpha Centauri the right place to search for life elsewhere?

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. NASA, ESA, and Hubble Heritage Team (STScI/AURA, Acknowledgment: T. Do, A.Ghez (UCLA), V. Bajaj (STScI)

Hidden stars, baby planets and blowup spaceships

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…
