Oct 11, 2023 · Only in the last two decades, with powerful new telescopes, cameras, and computers, have we finally achieved the precision necessary to measure the spectra of exoplanets. The first spectrum of an exoplanet, published in 2002 , was taken using the Hubble Space Telescope and showed evidence of vaporized sodium in the atmosphere of the exoplanet HD 209458 b.
Will we know life when we see it? The James Webb Space Telescope, launched in 2021, could get the first glimpses: the mix of gases in the atmospheres of Earth-sized exoplanets. Webb, or a similar spacecraft in the future, could pick up signs of an atmosphere like our own – oxygen, carbon dioxide, methane. A strong indication of possible life.
Apr 27, 2021 · The push and pull comes from orbiting planets, and the detection method is known as the radial velocity technique. And the next generation of space telescopes will bring a sea change in the planet search: measuring the atmospheres of the planets themselves. “So far, we’ve confirmed more than 4,000 exoplanets,” said Mario Perez, the chief ...
Sep 11, 2023 · This suggests the telescope should be able to detect life or alien civilizations on exoplanets within 40 light-years of Earth. But the team believes JWST could possibly detect signs of ...
Feb 24, 2024 · Potential Biosignatures on Exoplanets. The study found that for a pair of these nearby worlds, Proxima Centauri b and GJ 887 b, these telescopes are highly adept at detecting the presence of potential biosignatures. Of the two, findings show that only for Proxima Centauri b would the machines be able to detect carbon dioxide if it were present.

Jun 20, 2023 · Our space telescopes might detect a mixture of gases in its atmosphere that resembles our own. Computer models would offer predictions about the planet’s life-bearing potential. Experts would debate whether the evidence made a strong case for the presence of life, or try to find still more evidence to support such a groundbreaking interpretation.
