NASA’s UAP Study Team Releases Its Final Report

The NASA UAP independent study team recommends that NASA plays a prominent role in the whole-of-government effort to understand UAP by leveraging its extensive expertise to contribute to a comprehensive, evidence-based approach that is rooted in the scientific method. The team members specifically recommend that NASA utilize its existing and planned Earth-observing assets to probe the local environmental conditions associated with UAP that are initially detected by other means. In so doing, NASA can directly probe whether certain environmental factors are coincident with known UAP. They further recommend that NASA explore enhancing collaborations with the U.S. commercial remote-sensing industry, which offer powerful constellations of high-resolution Earth-observing satellites.

This Hubble image shows NGC 3156, a large lenticular galaxy some 73 million light-years away in the constellation of Sextans. The color image includes optical and near-infrared observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) instruments. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This image of SNR 1987A was taken with Webb’s Near-Infrared Camera. At the center, material ejected from the supernova forms a keyhole shape. Just to its left and right are faint crescents newly discovered by Webb. Beyond them an equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots. Exterior to that is diffuse emission and two faint outer rings. Image credit: NASA / ESA / CSA / M. Matsuura, Cardiff University / R.

Plasma is constantly streaming away from the Sun, forming the solar wind. A likely source of this plasma is coronal holes, regions of the Sun’s corona with magnetic field lines that open outward. Chitta et al. observed a coronal hole in the extreme ultraviolet using the ESA/NASA Solar Orbiter spacecraft and identified several types of small-scale jets within it. Large numbers of jets occurred during the observation, but each one lasted only a few dozen seconds. The authors calculated that the jets provide enough energy and plasma to supply a large fraction of the solar wind, at least during quiet periods.
