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.
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.
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.
All it took was a single email alert to send the world’s astronomers searching for the source of the latest gravitational wave detected.
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 gravitational wave itself is the least exciting part of the announcement from LIGO and Virgo. Observing this new source answers many longstanding questions.
International plan for a lunar space station may lag behind efforts by private companies.
New results from Italy and the US help us better estimate the position of the merging black holes that produced the gravitational waves.
Technology is driving a revolution in the way radio astronomers study the universe, and it could lead to new discoveries.
Cassini may be gone but the data it left behind could help reveal how long Saturn’s day is and how its magnetic field is generated.
Astronomy on the continent has been given a much needed boost with Ghana’s converted radio telescope between it and South Africa, to conduct scientific observations.
Despite not being able to see them, we know a fair bit about our exoplanet neighbours.
At a time in the sun’s cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal mass ejections. What effects will Earth feel?
How exactly do the stars twinkle in the night sky? As it turns out, the answer is full of hot air… and cold air.
Scientists used to believe that snowfall could never reach the ground.
For centuries, scientists have known when and where eclipses will be visible. They pack their bags, head for the line of totality and hope for the best – which doesn’t always happen.
Humanity is the real target for these recordings which continue to inspire us to better understand ourselves and our place in the cosmos.
Gravity waves recorded in the sun for the first time reveal some interesting facts.
Franklin advanced a scientific – not supernatural – understanding of astronomical events such as eclipses. His satirical character ‘Poor Richard’ mocked those who bought into astrological predictions.
