Scientists spotted an incredibly old star breathing its dying breath

August 5th, 2019

Age is a relative thing. With our finite (and relatively short) lifespans, humans tend to think of anything older than 100 years as being “really old,” but when talking about astronomy, a century (or even a million years) is a drop in the bucket. So, when astronomers say they’ve discovered an incredibly old star, you …

Hubble captured gorgeous snapshot of a massive distant galaxy

Thanks to the nature of light and the fact that it can only move so fast, peering at objects far away means that astronomers can effectively look back in time. Well, “can” is a bit of an understatement since they’re quite literally forced to see things as they were, based on how far away the …

Astronomers discover massive ring of gas circling our black hole

June 6th, 2019

The center of the Milky Way galaxy is somewhere you wouldn’t want to be. We have it pretty easy here on Earth, orbiting our star and staying out of everyone’s way, but deep within the heart of our galaxy, a monster lurks. It’s a supermassive black hole known as Sagittarius A* (that’s pronounced “A star”, …

Astronomers spot one of the oldest stars ever

November 5th, 2018

Our Solar System is incredibly old by human standards. The Sun, sitting in the center, is thought to be just over 4.6 billion years old, which is an almost unfathomable amount of time to you and I. But it’s actually not all that impressive when it comes to stars. A new survey of one particular …
