Radiation astronomy/Lensings

This image shows a cluster of yellow galaxies near the middle of the photograph. Credit: STScl/NASA.

The image at right shows several blue, loop-shaped objects that are multiple images of the same galaxy, duplicated by the gravitational lens effect of the cluster of yellow galaxies near the middle of the photograph. The lens is produced by the cluster's gravitational field that bends light to magnify and distort the image of a more distant object.

Hypotheses

Main article: Hypotheses

1. The use of satellites should provide ten times the information as sounding rockets or balloons.

A control group for a radiation satellite would contain

1. a radiation astronomy telescope,
2. a two-way communication system,
3. a positional locator,
4. an orientation propulsion system, and
5. power supplies and energy sources for all components.

A control group for radiation astronomy satellites may include an ideal or rigorously stable orbit so that the satellite observes the radiation at or to a much higher resolution than an Earth-based ground-level observatory is capable of.
