Stephen Hawking inspired people with his work on black holes and other mysteries of the universe. Many were quick to pay tribute to the theoretical physicist who died today in the UK, aged 76.

Hawking’s most famous book, A Brief History of Time, sold 10 million copies and was translated into 40 languages, skyrocketing to the top of the bestseller lists in the US and UK.
Strangely behaving galaxies force scientists to rethink whether the universe really is uniform.
Cosmologists who were hoping to be the next Einstein have had to bin their theories.
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.
Astronomers have finally confirmed the source of the latest detected gravitational waves was the collission of a pair of neutron stars, what they’d been searching for all along.
Efforts to see the afterglow from a neutron star merger were nearly thwarted by bad weather and a cyber attack on an Australian telescope.
The first reliable measure of the 3D shape of galaxies and their rotation helps to shed light on their history.
We still can’t see the dark matter thought to make up about a quarter of the universe, but at least now we have a map of its structure.
Many scientists say there’s no purpose to life – but a theoretical study suggests there could be.
Is dark energy just an illusion, as is often suggested? To resolve the dilemma, interpreting the basic principles of general relativity in a complex Universe may need a rethink.
The idea that we live in a ‘multiverse’ made up of an infinite number of parallel universes has long been considered a possibility.
A new book explores some of the big questions of why the universe exists and why it seems fine-tuned for life.
We continue to search for intelligent life elsewhere in the universe. But if we find ET there are those who question whether we should make contact or not.
New research out this month has led to speculation that the acceleration of the expanding universe might not be real after all. So what’s really going on?
A new telescope aims to figure out what became of the universe’s original atoms once the first stars began to shine.
What’s particularly exciting about “first light” images from South Africa’s MeerKAT radio telescope is that they prove Africa is a rising star in the world of astronomy.
The universe is expanding faster than expected, but we don’t know what’s driving it. Here are a few of the possible explanations, from dark energy to a modification of general relativity.
It’s all relative – why scientists understand time in a completely different way.
The detection of gravitational waves is the final confirmation of Einstein’s theory of general relativity, and opens up a new window into the cosmos.
