Mentions of total solar eclipses in ancient history help researchers pinpoint precise dates of notable events.
When the Moon blocks the Sun during an eclipse, utility suppliers have to pull power from the grid to make up for gaps in solar energy.
If we need to use forensic techniques in space, we’ll need to understand how things behave differently in microgravity.
The next generation of spacesuit needs to do more than simply protect an astronaut from the vacuum of space.
The discovery raises big questions about widely accepted models of galaxy formation.
The mission provided details about how to deflect an asteroid should one threaten Earth in future.
We know particles from spacecrafts are in the stratosphere. But what this means for the ozone layer or the climate is still unknown.
The extreme object could tell us more about the environment around black holes.
Can astronauts spend prolonged time in close quarters millions of miles from Earth without killing each other?
The capability for attacking satellites in space using cyber technology is advancing fast
Destroying satellites in space can lead to cascades that are hard to predict.
Russia isn’t likely to put nuclear missiles in space, but their reported anti-satellite weapon is just as alarming. An expert on nuclear strategy explains.
The observation could fill in gaps in our knowledge about planet formation.
Megaconstellations of satellites are hindering the most powerful tool for space exploration: telescopes.
Spaceplanes seemed out of favour when the shuttle was retired in 2011; they now seem to be making a comeback.
Projects under NASA’s CLPS program – including the Odysseus lander that made it to the lunar surface – will probe unexplored questions about the universe’s formation.
While NASA rovers on the surface of Mars look for hints of life, researchers back on Earth are studying ‘echoes of life’ from ancient basins – hoping that the two sites might be similar.
Mars has been a popular destination since space exploration began – and there are plenty of people who’d love to go there.
As space travel and lunar exploration becomes a near-future reality, we should consider the impact of human activities on the lunar environment.
