public.nrao.edu
The NRAO Public site is the public-facing hub of the National Radio Astronomy Observatory, offering educational resources, news, outreach materials, and visitor information about radio astronomy and its facilities (VLA, GBT, VLBA).
ALMA Science Portal
Operational hub for the Atacama Large Millimeter/submillimeter Array: technical handbooks, proposal preparation tools, sensitivity calculators, CASA reduction guides, and the public science archive. Users learn how millimetre interferometric observations are proposed, calibrated, and retrieved for their own analysis.
HEASARC
NASA's archive for high-energy astrophysics, holding data from Chandra, XMM-Newton, Swift, Fermi, NuSTAR and earlier missions alongside HEASoft analysis software, catalogue browsers and tutorials. Provides the route from mission catalogue to reduced X-ray or gamma-ray spectra.
Essential Radio Astronomy
Graduate textbook built from the NRAO summer school course, covering radiation fundamentals, antennas, receivers, interferometry, synchrotron and free-free emission, pulsars, and spectral lines. Readers finish able to work quantitatively with radio telescope sensitivity and source physics.
Chandra X-ray Observatory
Official site of NASA's Chandra X-ray Observatory, run by the Chandra X-ray Center, with mission background, explained science results, image archives and educational material. It shows how X-ray observations reveal black holes, supernova remnants, galaxy clusters and other high-energy phenomena.
