Question

Two identical stars are moving in a circular orbit around one another with an orbital separation of 2 AU. The system lies
200 light-years from Earth. If we happen to view the orbit head-on, how large a telescope would we need to resolve the
stars, assuming diffraction-limited optics at a wavelength of 2 μm?

You observe two randomly chosen stars 10,000 lightyears from Earth. One is in the disk of the Milky Way, the other in a direction perpendicular out of the disk. Compare the likely luminosity, doppler shift, metallicity, age, and color of these two stars.
The angular size of the black hole at the center of M87 is about 10microarcseconds, or 2.8 x 10-9 degrees. Ignoring atmospheric seeing, whatwould be the diameter (in meters) required for a single telescope to resolve an image of this black hole in the near-infrared (wavelength = 1 micrometer)?

The images above show real X ray data of the Cassiopeia A supernova remnant and a spectrum extracted from that data--you can see several emission lines including the silicon line near 6.6 angstroms (0.66 nm). If the emission line created by silicon normally has a wavelength of 0.6648 nm (nanometers), but is measured in the spectrum to have a wavelength of 0.6599 nm, how fast is the gas moving?
