Observational astronomy is a division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models. It is the practice and study of observing celestial objects with the use of telescopes and other astronomical instruments.

Galileo Galilei turned a telescope to the heavens and recorded what he saw. Since that time, observational astronomy has made steady advances with each improvement in a variety astronomical instruments and related methods. — Wikipedia

    on February 22, 2019 at 12:08 pm

    An international research team including astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has combined radio telescopes from five continents to prove the existence of a narrow stream of material, a so-called jet, emerging from the only gravitational wave event involving two neutron stars ever observed. With its high sensitivity and excellent performance, the 100-meter radio telescope in Effelsberg played an important role in the observations. […]

    A new astronomical spectrograph built by a Penn State-led team of scientists provides the highest precision measurements to date of infrared signals from nearby stars, allowing astronomers to detect planets capable of having liquid water on their surfaces that orbit cool stars outside our solar system. The Habitable Zone Planet Finder (HPF) allows precise measurement of a star's radial velocity, measured by the subtle change in the color of the star's spectra as it is tugged by an orbiting […]

  • In colliding galaxies, a pipsqueak shines bright
    on February 20, 2019 at 8:21 pm

    In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using observations from NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission shows that a much smaller object is competing with the two behemoths.
