New spacecraft techniques propose using CubeSats, laser rangefinding, and precise Doppler measurements to determine the mass ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

The energy transition requires not only the development of new technologies, but also their reliable and economical operation. For many years, the Institute of Solar Research has been developing ...

Thin films are two-dimensional (2D) material layers deposited on a bulk substrate, possessing a thickness of a few nanometers to impart properties that cannot be realized by base materials. The unique ...

Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface. That is important because a star’s ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Large contractors are putting a new standard for productivity measurement to the test in the hope of producing better project process controls. The new standard, which was adopted last fall as ASTM ...

Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...

A recent study found that the more accurate methods for analyzing hydrogen consumption are the feed-total liquid product (TLP) H-content analysis and chemical analysis methods. These comparable ...
