For 1st time, astronomers measure mass and distance of a rogue planet
Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy ...
We live in a world defined by inches, feet and miles (or centimeters, meters and kilometers, if you prefer), and it’s not difficult for most of us to comprehend sizes and distances given in these ...

How astronomers measure distance without travelling anywhere
It’s a bit mind-bending to realise that everything we know about the scale of the universe comes from people stuck […] ...
Extra stellar systems are so far away from our own that we couldn’t even hope of developing a tape measure long enough to determine how far away they really are. On the other hand, astronomers can ...
Pasadena, CA -- Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement ...
A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and ...
NASA's Hubble Space Telescope spotted a blazing heat from a bright, lonely spiral galaxy called UGC 9391. But even though it lacks a companion, it serves as a guiding light for every astronomer who is ...
THE distance of the sun from the earth or, speaking more correctly—for the distance is, of course, variable—the semi-major axis of the earth's orbit, is the most important constant in astronomy. It ...
