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.
An astronomer explains how. why and when eclipses happen, what scientists can learn from them, and what they would look like if you were standing on the Moon.
In five or seven billion years time, the Sun’s life will come to an end. And it will be really spectacular - if you’re watching from far enough away.
What caused the Big Bang is still a mystery. And that’s just one of the many unanswered questions, in spite of everything we do know about the birth of the Universe.
Astronomers in Puerto Rico have picked up signal from a faint star that’s not like anything they’ve seen before.
Efforts to reduce the gender gap and encourage more women in Australian astronomy have been rewarded this week.
Studying mysterious neutron stars could uncover the secrets of exotic physics – and a way to navigate the stars.
