# FLIP software detects exoplanet in JWST archive data missed by standard processing

The imaging tool retrieved a known planet that conventional telescope workflows failed to resolve.

FLIP software has successfully detected exoplanet 51 Eri b in two year old archived JWST data, where standard processing methods could not resolve the object.[^1]

Phys.org reports the tool improves JWST faint object detection sensitivity by between 2 and 15 times relative to standard methods.[^2]

Rather than using reference star subtraction, FLIP works by modelling the physical instabilities of the JWST instrument to simulate and remove residual glare from host stars, according to Scientific American.[^3]

Rodrigo Ferrer-Chavez, an astronomer at Northwestern University, led development of the FLIP software. The work was published in Nature.[^4]

This result suggests there may be additional exoplanets already captured in existing JWST archive data that have not yet been identified.
