NASA Telescope Idea Could Spot Vegetation on Distant Exoplanets
NASA states it could detect “surface features” and even “hints of habitability” on distant planets.
NASA is financing research for a conceptual telescope called a “solar gravitational lens” (SGL) that can allow us to observe remote exoplanets at a fantastic resolution– a futuristic endeavor that might assist discovery at last if we are alone in the universe.
The project got Phase I and II funding under the NASA Innovative Advanced Concepts (NIAC) program, an incubator for substantially futuristic and otherworldly concepts.
The concept is to “directly image a habitable Earth-like exoplanet within our stellar neighborhood,” according to a description of the project. Over six months of monitoring, we might get a resolution of around 25 km, “sufficient to see surface attributes and indicators of habitability.”
NASA’s telescope imaging
A NASA image going along with the announcement reveals an artist’s rendition of images the telescope might get– revealing greenery on the surface of a distant planet.
Albert Einstein first predicted 84 years ago that beams of light skirting the edges of the Sun merge into a lens at around 550 astronomical units (approximately 82 billion kilometers) away.
Slava Turyshev, a physicist at NASA’s Jet Propulsion Laboratory and lead author of a related study uploaded to the preprint archive arXiv in February, suggests the phenomenon can permit us to obtain noticeably detailed photos of distant Earth-like planets.
“In the strong interference region of the SGL, this light is substantially intensified, forming the Einstein ring around the Sun, representing a distorted image of the prolonged source,” reads the paper.
An image included in the NASA announcement also shows Turyshev’s representation of what an exoplanet close-up can resemble utilizing an SGL.
There is a significant difficulty we would undoubtedly have to overcome. We would certainly have to carry a “meter-class telescope with a solar coronagraph” to a phenomenal distance from the Sun. For perspective, Voyager I is presently only around 123 astronomical units away from Earth has actually gotten to the edges of the solar system in 2012– the furthest we have ever before sent out man-made things.
Turyshev suggests that a “swarm architecture for smallsats” with solar sails for power could fly out along the SGL to observe “multiple planets/moons to keep expenses reduced and usefulness as high as feasible of an exosolar system” at the same time.
