Measure all the light in the world by sending a new instrument into space


Following a mission a few days ago to measure all the light emitted by the universe throughout history, a new instrument was sent into space for a short time.

According to News i and quoted by New Atlas, In this project, Cyber-2 (CIBER-2) scans the infrared light rays of celestial bodies to look for stray stars hidden among galaxies.

Using patterns of infrared light can be used to locate galaxies, examining these lights gives astronomers information about how stars and other objects are distributed in space.

On Sunday, June 6, Cyber-2 made its first of five scheduled flights. The device was launched on NASA’s Black Brant IX rocket from New Mexico and soared to an altitude of 300 kilometers and returned to Earth after 10 minutes.

During its journey, Cyber-2 scans and scans part of the sky for eight times the full moon, measuring infrared radiation at six wavelengths so that scientists can analyze them and obtain information about stars and other celestial bodies. Bring.

This mission will help you find answers to some basic questions. Most of the stars are thought to be inside galaxies, but data from the Spitzer Space Telescope show that there is more light in space based on the number of galaxies we know.

Two explanations for this are provided by two different groups. One group says the light is from the first stars and black holes ever formed, and that the “cyber” mission provides evidence of stars wandering outside the galaxy. Cyber-2 can help solve this problem by examining the sky because it can examine the sky at different wavelengths that Spitzer and mainstream cyber cannot. For example, the first stars and black holes in the universe may be immersed in a mist of hydrogen that can affect the color spectrum of their light, but new stars do not pass through hydrogen so they have different light.

Cyber-2 has four more flights in the next five years, and its data will help design future telescopes.

The SPHEREx Space Observatory will also go into space in 2024 to study 102 wavelengths in two years.
