Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy ...

For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise ...

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 ...

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 ...

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 ...

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 ...

Click anywhere on this site, and you’ll likely run into a measurement in terms of light-years, solar masses, astronomical units, or arcminutes. These units are unique to astronomy, and all can be ...

Researchers jointly developed an originative radio receiver DESHIMA (Deep Spectroscopic High-redshift Mapper) and successfully obtained the first spectra and images with it. Combining the ability to ...

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 ...

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 ...

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 ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets ...
