Have you ever wondered how astronomers measure the distance to other objects in the universe? How do they make claims that this nebula is 1,500 light years distance or that galaxy is 2.5 million light ...

A way of estimating more accurate distances to the thousands of so-called 'planetary nebulae' dispersed across our Galaxy has just been announced by a team of three astronomers. A way of estimating ...

Astronomers directly measured the distance to a region on the far side of our Milky Way Galaxy, past the Galaxy's center. Bill Saxton, NRAO/AUI/NSF; Robert Hurt, NASA Using a 180-year-old technique ...

In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax—setting the first scale of the universe. Astronomers from the U ...

Good news, everyone! We’re not intergalactic hicks after all! Turns out that our solar system is located in a large spiral branch called the Local Arm, a prominent feature of the Milky Way galaxy. Top ...

Astronomers have accurately measured the distance from Earth to a black hole for the first time. Without needing to rely on mathematical models the astronomers came up with a distance of 7800 light ...

Scientists using NASA’s Hubble Space Telescope have for the first time precisely measured the distance to one of the oldest objects in the universe, a 13.4 billion-year-old cluster of stars born ...

A way of estimating more accurate distances to the thousands of so-called "planetary nebulae" dispersed across our Galaxy has just been announced by a team of three astronomers based at the University ...
