Precision measurement under impact—when the balance itself becomes the object of measurement
How do you take measurements using one of the most sensitive scales in the world? Researchers at TU Wien have demonstrated ...
A new study published in Nature Astronomy describes the most luminous object ever observed by astronomers. It is a black hole with a mass of 17 billion Suns, swallowing a greater amount of mass than ...
Although mass is the most important property of stars, it has proved very hard to measure for the lowest mass objects in the universe. Thanks to a powerful new camera, a very rare, low-mass companion ...
