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 ...

Don't miss the big stories. Like us on Facebook. Astronomers quickly become used to dealing with huge numbers. For example, in any one lecture, I might declare that the sun emits some 400 billion ...

Gaia, through parallax measurement and other readings, gives the closest look at the Milky Way Galaxy to date.

Because they are densely covered in dust, the regions in which stars are formed are particularly difficult to study. Now there is an impressive map.

Astrometry at centimeter wavelengths using Very Long Baseline Interferometry is approaching accuracies of ∼1 μas for the angle between a target and a calibrator source separated by ≲1° on the sky. The ...

A reader from Jackson, Mo., asks, "How do astronomers know the distances to the various objects they talk about?" The answer is that astronomers use a "boot strap" process to determine distances over ...

For most of us, the countless bright spots in the nighttime sky all seem to be stars. But in fact, some of those spots are actually planets, or distant suns, or even entire galaxies located billions ...
