The artificial light emitted from Proxima B may be detectable with the James Webb Space Telescope

Such as

This is because JWST can see the narrow band light that can point towards the LED, because the planet’s atmosphere can be distinguished. In this way, researchers can use tools in the observatory to determine how much energy is being transmitted on the planet, and then calculate the light curves to see if they match those of the LED light source. To reach the conclusion of artificial light detection, Loeb used the JWST Exposure Time Calculator, which allows astronomers to predict what might be detected over a period of time based on preset settings, even before the observatory launch. It enabled the team to determine the probability of detecting different flux values ​​and those values ​​at a wavelength that corresponds to the levels of artificial light expected from a civilization living in perpetual darkness. The team says: “Proxima b is intertwined with the tides and if it has a permanent side of day and night, civilization can illuminate the night side with mirrors that are launched into orbit or placed at strategic points.” “In this case, the bright lights on the permanent night side should be very strong, and thus there is a greater chance of detection by JWST,” he continues. In addition to this:We discovered that JWST would be able to demonstrate artificial lighting for standard LEDs 500 times stronger than those currently on Earth, and for artificial lighting with an intensity comparable to that on Earth.” He.

In recent research from The Ohio State University, which also looked at JWST’s capabilities in relation to biometrics, the research team found that JWST in 60 hours could reveal a possible sign of life on exoplanets. Ammonia can be detected around gaseous dwarf planets after only a few revolutions. The Ohio team revealed results Research During the APS Meeting April 2021. Sources: ScienceDaily, Phys.org
