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 ...

In this video, a flat earther named CC launches into one of his most unhinged rants yet — insisting that Alpha Centauri is ...

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 ...

A NASA parallax experiment involving New Horizons shows the probe now sees some stars in slightly different positions than we do on Earth, revealing just how far the spacecraft is from home. You can ...

NASA's New Horizons spacecraft, which yielded the first close-up photos of Pluto, has managed to snap photos of an "alien sky" more than 4.3 billion miles from Earth. The craft took images of nearby ...

Over the years, as I've enjoyed sharing my love of astronomy with you, I’ve rattled off the distances to many stars and galaxies. Except for within our solar system, trying to express those distances ...

THE Observatory of Yale College has acquired a deservedly high reputation for the zeal with which the staff has prosecuted the inquiry into stellar parallax and the standard of accuracy consistently ...

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 ...

If you’re lost somewhere on the earth, you can use GPS or public landmarks to find your way back. Navigation in the vastness of space isn’t so easy, however — especially if you’re on a spacecraft ...

SOME years ago Dr. Chase, of the Yale University Observatory, communicated to the Astronomical and Astrophysical Society of America the results of a survey which he had carried out, in collaboration ...
