Powerful black holes might grow up in bustling galactic neighborhoods

An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.

How old is the universe exactly? A new theory suggests that it’s been around for twice as long as believed

A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.

India’s Chandrayaan-3 landed on the south pole of the Moon − a space policy expert explains what this means for India and the global race to the Moon

India became the first country to land near the south pole of the Moon, a notoriously difficult achievement that also marks them as the fourth country to land on the Moon.

Caroline Herschel was England’s first female professional astronomer, but still lacks name recognition two centuries later

Astronomer Caroline Herschel’s work discovering and cataloging astronomical objects in the 18th century is still used in the field today, but she didn’t always get her due credit.

Researchers dig deep underground in hopes of finally observing dark matter

To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.

Measuring helium in distant galaxies may give physicists insight into why the universe exists

The way particles interacted while the universe was forming seconds after the Big Bang could explain why the universe exists the way it does – a physicist explains matter-antimatter asymmetry.
SETI has been listening for markers that may indicate alien life – but is doing so ethical? Donald Giannati via Unsplash

First contact with aliens could end in colonization and genocide if we don’t learn from history

Three Indigenous studies scholars draw from colonial histories and explain why listening for alien life can have ethical ramifications.
