So scientists found a workaround. Instead of building one gigantic telescope, they placed smaller telescopes far apart and ...

Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in ...

A car length is about 15 feet. So if you’re traveling at 65 mph, and leave one car length for every 10 mph, you’d leave a ...

The “horizon” he points to isn’t a doorway to the divine, other scientists say. Yet, modern physics has been trying to answer questions once left to religion.

Some sci-fi movies take the genre extra seriously, using accurate technologies to ground their depiction of the future.

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by ...

It would be understandable if you stopped thinking as much about Pluto after it was “demoted” from being considered one of the nine planets sharing the Earth’s solar system to being classified as a ...
