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

Celestial News & Events – Sky & Telescope The essential guide to astronomy

  • This Week's Sky at a Glance, May 20 – 28
    by Alan MacRobert on May 20, 2022 at 8:44 am

    The advancing spring sends Vega high and Capella low. The Coma Berenices cluster glitters shyly way up, big and dim. Glance up anytime to check on changing Beta Lyrae. And now in the dawn, Jupiter aligns with Mars. The post This Week's Sky at a Glance, May 20 – 28 appeared first on Sky & Telescope.

    by Alan MacRobert on May 13, 2022 at 9:02 am

    The Moon becomes totally eclipsed, Corvus eyes Spica, Draco eyes Vega, and the last star of the rising Summer Triangle clears the horizon. The post This Week's Sky at a Glance, May 13 – 21 appeared first on Sky & Telescope.

    by Alan MacRobert on May 6, 2022 at 9:07 am

    The Moon aligns with Pollux and Castor – but how precisely for you? Three zero-magnitude stars form a far-flung spring triad. And with Libra and Bootes up, the two oldest things you will ever see await your binoculars or scope. The post This Week's Sky at a Glance, May 6 – 14 appeared first on Sky & Telescope.

    by Alan MacRobert on April 29, 2022 at 8:51 am

    Mercury passes the Pleiades at dusk. Jupiter passes Venus in the dawn as Mars and Saturn watch. And can you name the three brightest stars of these spring nights? Hint: They're all magnitude zero. The post This Week's Sky at a Glance, April 29 – May 6 appeared first on Sky & Telescope.

    on May 23, 2022 at 3:55 pm

    Nearly half of Sun-size stars are binary. According to new research, planetary systems around binary stars may be very different from those around single stars. This points to new targets in the search for extraterrestrial life forms.

    on May 18, 2022 at 3:33 pm

    A unique new instrument, coupled with a powerful telescope and a little help from nature, has given researchers the ability to peer into galactic nurseries at the heart of the young universe.

    on May 12, 2022 at 1:42 pm

    Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies.

  • Explosion on a white dwarf observed
    on May 12, 2022 at 1:26 pm

    When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super hot explosion and produce a fireball of X-ray radiation. A research team has now been able to observe such an explosion of X-ray light for the very first time.

  • Astronomers find 'gold standard' star in Milky Way
    on May 10, 2022 at 7:14 pm

    In our sun's neighborhood of the Milky Way Galaxy is a relatively bright star, and in it, astronomers have been able to identify the widest range of elements in a star beyond our solar system yet.

    As NASA's James Webb Space Telescope moves through the final phases of commissioning its science instruments, we have also begun working on technical operations of the observatory. While the telescope moves through space, it will constantly find distant stars and galaxies and point at them with extreme precision to acquire images and spectra. However, we also plan to observe planets and their satellites, asteroids, and comets in our solar system, which move across the background stars of our […]

  • The sun as you've never seen it before
    on May 19, 2022 at 1:03 pm

    Powerful flares, breathtaking views across the solar poles, and a curious solar "hedgehog" are among the haul of spectacular images, movies and data returned by Solar Orbiter from its first close approach to the sun. Although the analysis of the new dataset has only just started, it is already clear that the ESA-led mission is providing the most extraordinary insights into the sun's magnetic behavior and the way this shapes space weather.

    on May 16, 2022 at 9:27 pm

    Imagine walking through a dense, hazy fog in the middle of the night, seeing patches of light from cars and towns shimmering in the distance. It's nearly impossible to tell if the lights are deep in the fog or beyond it. Astronomers trying to find young stars face a similar problem: the light from stars they're hunting is shimmering through great big regions of hazy gas and dust in space, called molecular clouds.

    on May 16, 2022 at 4:30 pm

    This week, the world got its first-ever look at Sagittarius A*, the supermassive black hole in the center of our galaxy. The image of a hazy golden ring of superheated gas and bending light was captured by the Event Horizon Telescope, a network of eight radio observatories scattered across the globe.
