Not all planets are lucky enough to live in a neighborhood like our Solar System – some are doomed to roam the cosmos alone.

Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science fiction. Measuring the mass of such a small planet based ...

If you want to determine your mass, it's pretty easy. Just step on a scale and look at the number it gives you. That number tells you the gravitational pull of Earth upon you, so if you feel the ...

A team of MIT researchers has described a new method for finding the mass of exoplanets by studying the spectra of light passing through the planet's atmosphere. Because a planet's mass can tell us a ...

1. Arxiv – A LEGO Watt Balance: An apparatus to demonstrate the definition of mass based on the new SI National Institute of Standards and Technology (NIST) researchers have designed and built a watt ...

Astronomers report the exciting discovery of a new way to measure the mass of supermassive black holes in galaxies. By measuring the speed with which carbon monoxide molecules orbit around such black ...

A new type of thin-film acoustic-wave resonator that is capable of simultaneously measuring mass as well as temperature has been unveiled by an international team of researchers. It allows users to ...

The group's coupled microcantilevers measure mass on the cellular and subcellular scale by using self-excited oscillation, a process in which the feedback of an oscillating body controls the phase of ...

Researchers at MIT and Dana-Farber Cancer Institute have developed a new way to determine whether individual patients will respond to a specific cancer drug or not. This kind of test could help ...

I have a challenge for you. It is sort of like the Car Talk Puzzler except that there isn't one correct answer. So, a while ago I was looking at this super bounce ball. It was my kid's toy, so I just ...
