Artificial intelligence helps improve NASA's eyes on the Sun

A group of researchers is using artificial intelligence techniques to calibrate some of NASA's images of the Sun, helping improve the data that scientists use for solar research. The new technique was published in the journal ...

Reducing errors in X-ray photoelectron spectroscopy

X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It was developed in the 1960s and is accepted as a standard method in materials science. Researchers at Linköping University, ...

5 hidden gems are riding aboard NASA's Perseverance rover

More than halfway to the Red Planet, NASA's Perseverance Mars rover isn't just shuttling sophisticated science instruments and tubes to be filled with Earth-bound rock samples. It's carrying symbols, mottos, and objects that ...

Drones help calibrate radio telescope at Brookhaven Lab

Cosmologists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are experimenting with a prototype radio telescope, called the Baryon Mapping Experiment (BMX). Built at the Lab in 2017, the prototype ...

Image: ESA's Juice model cast in gold for antenna tests

In a decade's time, an exciting new visitor will enter the Jovian system: ESA's Jupiter Icy Moons Explorer, or Juice. As its name suggests, the mission will explore Jupiter and three of its largest moons—Ganymede, Callisto ...

Calibration

Calibration is a comparison between measurements – one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.

The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated.
