Schematic representation of the tilted accretion disk model. The black hole spin axis is assumed to be straight up and down in this illustration. The jet direction points almost perpendicular to the disk plane. The misalignment between the black hole spin axis and disk rotation axis triggers the precession of the disk and jet.

This Hubble image shows SDSS J103512.07+461412.2, a spiral galaxy some 23 million light-years away in the constellation of Ursa Major. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / R. Tully.

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.
