We really need the whole community working together if we want to make investments in these missions that are churning out exoplanet candidates, said Aurora Casselli, the deputy science lead for the NASA exoplanet archive at IPAC. A big part of what we do at XI is build tools that help the community go out and turn candidate planets into confirmed planets. The rate of exoplanet discoveries has increased in recent years. The database reached 500 exoplanets in just two years. This trend seems likely to continue. Casselli and her colleagues anticipate receiving thousands of additional exoplanet candidates from the ESA or the European Space Agency Gaia mission, which will be through a technique called astrometry and NASA's upcoming Nancy Grace Roman Space Telescope, which will discover thousands of new exoplanets primarily through a technique called gravitational microlensing. Future exoplanets. At NASA, the future of exoplanet science will emphasize finding rocky planets similar to Earth and studying their exoplanet biosignatures. Any characteristic, element, molecule, substance, or feature that can be used as evidence of past or present. NASA's James Webb Space Telescope has already analyzed the chemistry of overworldings, and has been studying the chemistry of over 100 exoplanet atmospheres. But studying the atmospheres of planets the size and temperature of Earth will require new technology. Specifically, scientists need better tools to block the glare of the star. In the case of an Earth-like planet, the glare would be significant. The Sun is about 10 billion times brighter, which would be more than enough to drown out our home planet's light if viewed by a distant observer.
