It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.

Astronomers have found the first observational evidence for a disc of material around a giant young planet at a distant star. It's a place they think moons can form.
Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.
The ancient question 'Are we alone?' has graduated from being a philosophical musing to a testable hypothesis. We should be prepared for an answer.
Exoplanet discovery can help us work out how the Earth will end its days.
Life could exist in another solar system in a different part our galaxy. Or in another galaxy far away. We don't have the perfect technology yet to study such far away places but we're still trying.
The new planet is believed to be orbiting Barnard's Star, a red dwarf that's not visible to the naked eye but one of the closest stars to our Solar System.
There are probably more than a million planets in the universe for every single grain of sand on Earth. That's a lot of planets. My guess is that there probably is life elsewhere in the Universe.
A moon has been spotted in a star system 4000 light years away – but its structure is confusing.
Anish Kapoor made “Cloud Gate”, a giant bean-shaped mirror in Chicago. Visitors play with the light in the city and its surroundings, where our future lays.
We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
Life could have evolved on exoplanets Kepler-452b and Kepler-62e, according to a new study.
Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
Images from New Horizons spacecraft provide more evidence about the surface of Pluto.
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.
When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase as Kepler retires.
There are plenty of astronomical things to watch out for this year beyond this week's lunar eclipse, including new Moon landings and a space station falling back to Earth.
Studying lunar eclipse could help us work out what's happening on exoplanets.
Google's artificial intelligence has been taught to look for planets around other stars. It's already making new discoveries that scientists have missed.
Having discovered an asteroid from outside the solar system for the first time, scientists are hoping there are more out there – illuminating the path to extrasolar worlds.
