Odd bursts, shifting expansion rates, and oversized early galaxies are pushing astronomers to refine physics, not rewrite it, ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening. Two of our best ways of measuring the cosmic expansion rate, the ...

Space scientists have shown off an incredible image of a “space egg.” NASA said Tuesday the Hubble Space Telescope has revealed a dramatic interplay of light and shadow in what’s called the Egg Nebula ...

Levon Pogosian receives funding from the Natural Sciences and Engineering Research Council of Canada. The work described in this article was enabled in part by support provided by the BC DRI Group and ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

Galaxy merger Arp-Madore 417-391 is on display in this new image captured by the Hubble Space Telescope's Advanced Camera for Surveys (ACS). The merger is about 670 million light-years away from Earth ...

On April 24, 1990, humanity launched a scientific revolution. I mean “launched” literally: on that date the space shuttle Discovery roared into the sky with the Hubble Space Telescope nestled in its ...

The universe is so vast, and the difficulty of discovering all that there is out in the cosmos is so great, that one might as well count all the grains of sand in the Sahara. But now, with the help of ...

What we know so far: Stars, like all living organisms, age according to predictable physical laws – or so astronomers once thought. Yet scattered throughout the Milky Way's oldest star clusters are ...
