Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving 'forgotten' scientists due credit.

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.
By sharing a location with the SKA, HIRAX will be able to conduct science in “radio-clear” skies across its wide frequency range.
To better detect gravitational waves, we need to build the quietest and most isolated thing on Earth. And make sure we don't drop those 40kg mirrors.
The planets we can see in the sky were known to the ancient Greeks as 'wandering stars'. But they appeared much earlier in the stories and traditions of Australia's Indigenous people.

A podcast all about nothing. From the importance of doing nothing to the ill-effects of time spent in solitary confinement and what nothing means in space.
It's all about the strong gravitational field of the black hole.
The blood moon myths are many and varied, but, at the end of the day, it's just an eclipse.
All five five planets visible to the naked-eye are on show in the night skies over Australia, and a Blood Moon on the way too.
A detector buried under more than a mile of ice in Antarctica has detected a high-energy subatomic neutrino and traced it to its origin, a blazar – a gargantuan black hole more than a billion times more massive than the sun.
Astronomy is accessible to anyone with a view of the sky.
An astronomer suggests an idea to piggyback on the ambitious Breakthrough Starshot project that aims to send nano spacecraft to Alpha Centauri at a major fraction of the speed of light.
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.
The tilt of Earth's axis as it orbits the sun results in the seasonal changes.
The SKA global project could be a driver that contributes to South Africa' economic growth.
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
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.
A three-dimensional look and listen at a dark cloud in space sheds new light on the mystery of how our solar system formed billions of years ago.
Using AI to search for ET might help us find things we couldn't even imagine we should look for, but to succeed we also have think critically about how we create and use that technology.
