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 ...

Parallax is the observed displacement of an object caused by the change of the observer's point of view. In astronomy, it is an irreplaceable tool for calculating distances of far away stars. When you ...

Add articles to your saved list and come back to them any time. 'How far away is it?" This is usually the first question that people ask when looking at a star through one of the Sydney Observatory's ...

This is a classic example of parallax (although this is fake parallax). You can create another example of parallax yourself. Hold you thumb out straight in front of your face at arms length. Now close ...

Using NASA’s Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away — 10 times farther than previously possible. Astronomers have developed ...

A wide open space (It could be your backyard or a park.) Two Hula-Hoops (Alternatively, you could use two flat rocks or bricks that you can sit on.) A yardstick or meterstick (Use one that has clear ...

For this study, astronomers listened to the 'music' of millions of stars -- some of them 15,000 light-years away.(Pixabay) For long, measuring the exact distance to celestial objects has been an ...

We’re putting the far side of the galaxy on the map. The most precise measurement yet of an object on the far side of the galaxy’s centre is paving the way for a definitive map of the other side of ...
