Scientists have enhanced the resolution of NASA's James Webb Space Telescope using a new technique called aperture masking interferometry (AMI), which corrects optical and electronic distortions in the telescope's images, enabling clearer observations of stars, planets, and black hole jets from a million miles away.
New high-resolution ALMA images of Fomalhaut's debris disk reveal a decreasing eccentricity with distance from the star, suggesting the presence of an unseen planet shaping the disk's structure through gravitational influence, providing insights into planetary system evolution.
The JWST studied the nearby star Epsilon Eridani, detecting a faint signal that could be a planet but was inconclusive due to noise artifacts, and ruled out the presence of larger planets further out. The study also introduced a new observational technique called a 'three-roll' strategy, which could enhance JWST's ability to detect faint objects by 20-30%, advancing future exoplanet research.
