Multi-band spectra of the Fermi LAT source to the south of SNR W28. The red squares in the GeV regime are the LAT data, where the red and black errors on the flux are statistical and systematic, respectively. The radio emission (Handa et al. 1987; Gómez et al. 1991) is modeled by synchrotron radiation, while the gamma-ray emission is modeled by different combinations of π0-decay (long-dashed curve), bremsstrahlung (dashed curve), and IC scattering (dotted curve). The sum of the three components is shown as a solid curve. Details of the models are described in the text.

This is one segment of an infrared portrait of dust and stars radiating in the inner Milky Way. More than 800,000 frames from NASA's Spitzer Space Telescope were stitched together to create the full image, capturing more than 50 percent of our entire galaxy.

 

As inhabitants of a flat galactic disk, Earth and its solar system have an edge-on view of their host galaxy, like looking at a glass dish from its edge. From our perspective, most of the galaxy is condensed into a blurry narrow band of light that stretches completely around the sky, also known as the galactic plane.

 

This segment extends through the constellations Scutum and Serpens Cauda. While most of these features are unseen in visible light due to foreground dust, the relatively nearby Eagle Nebula is easily seen in both visible and infrared light (upper left).

 

The swaths of green represent organic molecules, called polycyclic aromatic hydrocarbons, which are illuminated by light from nearby star formation, while the thermal emission, or heat, from warm dust is rendered in red. Star-forming regions appear as swirls of red and yellow, where the warm dust overlaps with the glowing organic molecules. The blue specks sprinkled throughout the photograph are Milky Way stars.

 

This survey segment spans galactic longitudes of 16.5 to 24.8 degrees and is centered at a galactic latitude of 0 degrees. It covers about two vertical degrees of the galactic plane.

 

This is a three-color composite that shows infrared observations from two Spitzer instruments. Blue represents 3.6-micron light and green shows light of 8 microns, both captured by Spitzer's infrared array camera. Red is 24-micron light detected by Spitzer's multiband imaging photometer. This combines observations from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) and MIPSGAL projects.

I Think there must be at least one amateur radio operator here too. That's quite a beam and multiband dipole.
