The two images (above) that appeared in the news story “New star found near Sol” show the star’s proper motion, not its parallax. Proper motion is the apparent movement of a star across the sky year ...

No, but it was considered. The reason parallax measurements weren’t taken with Voyager or any other interplanetary spacecraft is simply that astronomers can do better from the ground or with dedicated ...

NASA's New Horizons deep-space probe has, for the first time, returned images to Earth that showed stellar parallax, or how the positions of stars shift when seen from two different places. This could ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Hurtling through interstellar space 4.3 billion miles from home ...

Queen guitarist (and astrophysicist) Brian May, a member of the New Horizons science team, uses his patented OWL viewer to check out the stereo images of Proxima Centauri that he created by combining ...

It isn't easy to measure the distance of stars. We can't travel to them, counting the miles as we go, nor can we simply say that brighter stars are closer and dimmer ones more distant. Instead, we ...

Try this experiment: extend your thumb at arm’s length and close one eye at a time. Your thumb will seem to ‘jump’ between two positions as you switch the eye that is closed. That jump is known as ...

A new method of measuring the distances between stars enables astronomers to climb the 'cosmic ladder' and understand the processes at work in the outer reaches of the galaxy. Astronomers from the ...

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 yet another novel way to use the ...

Astronomers have developed a new way of measuring cosmic distances by listening to the frequencies of "music" played by vibrating stars that collectively act as a vast orchestra of different cosmic ...
