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

    Circle the date November 21st on your calendar, when a brief but potentially spectacular meteor storm might light up the night. The post Intense Meteor Outburst Expected from the Alpha Monocerotids appeared first on Sky & Telescope.

  • Capturing the Transit of Mercury
    by The Editors of Sky & Telescope on November 12, 2019 at 7:35 pm

    Though clouds blocked the sky for many yesterday, those with a clear view had the chance to see tiny Mercury cross the face of the Sun. The post Capturing the Transit of Mercury appeared first on Sky & Telescope.

  • Don’t Miss Monday’s Rare Transit of Mercury
    by Bob King on November 6, 2019 at 4:49 pm

    On Monday, November 11th, Mercury will pass directly in front of the Sun and look a tiny black dot silhouetted against the brilliant solar disk. The event, called a transit, occurs approximately 13 times a century. The post Don’t Miss Monday’s Rare Transit of Mercury appeared first on Sky & Telescope.

  • Central mysteries of solar physics
    on November 16, 2019 at 12:03 am

    Scientists have shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

    Researchers are first to combine 3D climate modeling with atmospheric chemistry to explore the habitability of planets around M dwarf stars, which comprise about 70% of the total galactic population.

  • Black hole mergers: Cooking with gas
    on November 13, 2019 at 8:31 pm

    Gravitational wave detectors are finding black hole mergers in the universe at the rate of one per week. If these mergers occur in empty space, researchers cannot see associated light that is needed to determine where they happened. However, a new study suggests that researchers might finally be able to see light from black hole mergers if the collisions happen in the presence of gas.

    Twenty-four years ago, Swiss astronomers Michel Mayor and Didier Queloz discovered the first planet orbiting a sun-like star outside our solar system—a milestone recognised by this year's Nobel prize in physics. Today we know of thousands more 'exoplanets," and researchers are now trying to understand when and how they form.

    Gravitational wave detectors are finding black hole mergers in the universe at the rate of one per week. If these mergers occur in empty space, researchers cannot see associated light that is needed to determine where they happened. However, a new study in The Astrophysical Journal Letters, led by scientists at the American Museum of Natural History and the City University of New York (CUNY), suggests that researchers might finally be able to see light from black hole mergers if the collisions […]

    Is Earth the only habitable planet in the universe or are there more worlds somewhere out there that are capable of supporting life? And if there are, what might they look like? In a bid to answer these fundamental questions, scientists are searching space for exoplanets: distant worlds that orbit other stars outside our solar system.
