Back when Henk Hoekstra started his PhD, atmosphere turbulence and optical imperfections prevented us from accurately observing dark matter. He tells us why Euclid is a game changer.

Astrophysicist Jacco van Loon joins us on The Conversation’s Curious Kids podcast.
The Netflix series ‘3 Body Problem’ is based on Liu Cixin’s scifi novel that follows what happens to the alien residents of a planet that orbits two stars.
Tau neutrinos are notoriously difficult to spot in detectors like IceCube. But researchers have managed to isolate 7 candidates.
When astronomers focused on the galaxy NGC 4383, they didn’t expect the data to be so spectacular. This is the first detailed map of gas flowing from this galaxy as stars burst within.
Where specialized algorithms fail to classify star-borne pulses, human volunteers with just a little training can step in.
Astronomers caught the bizarre ‘awakening’ of an incredibly rare magnetic star.
Some ancient texts record what were likely dying stars, faintly visible from Earth. If close enough, these events can disturb telescopes and even damage the ozone layer.
The largest study yet of ‘twin stars’ shows planetary orbits may be less stable than we thought.
Eclipses have inspired myths, predictions and scientific discoveries. The total solar eclipse occurring on April 8 provides a once-in-a-lifetime opportunity to engage with science and the cosmos.
With the help of a magnifying glass 4 million lightyears wide, astronomers may have solved the riddle of what burned away the hydrogen fog that pervaded the early universe.
The black hole J0529-4351 is 500 trillion times brighter than the Sun.
Orbital resonance is kind of like musical harmony, but systems that display it are far more rare than songs with harmonic melodies.
The astronomical community has thrived and world-class astronomical facilities have been established in South Africa.
You might hate winter, but at least you know what to expect every year. Other planets have wobbly axes that lead to wild, unpredictable seasons.
The nature of dark energy remains one of the biggest puzzles in cosmology.
Pictures of black holes have a white outline around them when photographed, due to one of black holes’ unique and key features.
Sound needs matter to propagate, so the vast vacuum of space is not just empty − it’s silent.
With an evidence-based strategy and careful evaluation, gender parity in science is achievable.
The universe is expanding faster than physicists would expect. To figure out what processes underlie this fast expansion rate, some researchers are first trying to rule out what processes can’t.
