Telescope Tag-Team Discovers Galactic Cluster’s Bizarre Secrets

Towards the center of our Milky Way Galaxy, in the constellation Sagittarius,
astronomers have discovered 10 monstrous neutron stars. Astronomers already knew
that 39 pulsars call Terzan 5 home. With the teamwork of the U.S. National
Science Foundation Green Bank Telescope (NSF GBT) and the South African Radio
Astronomy Observatory’s MeerKAT Telescope, ten more have been added to the
count.

#RADIOIMAGEOFTHEWEEK




WHAT ARE EMISSION LINES?

Inside a spectrometer, a beam of white light (typical incandescent light bulb,
sunlight, etc.) is broken into its actual wavelengths, what we call colors.
Radio waves, if we could see them like this, would glow way off the chart to the
left. Infrared light would be glowing next to the red, between radio and white
visible light.

The National Radio Astronomy Observatory is a facility of the National Science
Foundation operated under cooperative agreement by Associated Universities, Inc.
Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities
for use by the international scientific community. NRAO telescopes are open to
all astronomers regardless of institutional or national affiliation. Observing
time on NRAO telescopes is available on a competitive basis to qualified
scientists after evaluation of research proposals on the basis of scientific
merit, the capability of the instruments to do the work, and the availability of
the telescope during the requested time. NRAO also provides both formal and
informal programs in education and public outreach for teachers, students, the
general public, and the media. The National Science Foundation (NSF) is an
independent federal agency created by Congress in 1950 "to promote the progress
of science; to advance the national health, prosperity, and welfare; to secure
the national defense..." AUI collaborates with the scientific community and
research sponsors to plan, build, and operate cutting-edge facilities. We
cultivate excellence, deliver value, enhance education, and engage the public.
