For the first time scientists have located the home galaxy of a one-off fast radio burst. Here’s how they did it – and what they learned about the galaxy.
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.
The first 60 satellites from Elon Musk’s planned low orbit internet network have lit up the skies. But with more planned, astronomers say the satellites could ruin their work.

About 5 percent of all UFO sightings cannot be easily explained by weather or human technology. A physicist argues that there’s compelling evidence to justify serious scientific study and that the skeptics should step aside – for the sake of humanity.
Astronomers have indirectly spotted some of the first stars in the universe by making their most distant detection of oxygen in a galaxy that existed just 500m years after the Big Bang.

Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
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.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.
A precursor to the Square Kilometre Array- the MeerKAT telescope - is being built right now and remarkable progress has been made in the last 12 months.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
Until the recent observation of merging neutron stars, how the heaviest elements come to be was a mystery. But their fingerprints are all over this cosmic collision.
A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of ‘multi-messenger’ observations.
We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.
