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, June 24 – July 2
    by Alan MacRobert on June 24, 2022 at 9:12 am

    The crescent Moon returns to the evening, crossing Leo. The five-planet lineup continues at dawn; catch it while you still can. And for skywatchers at northern latitudes, we're entering noctilucent cloud season. The post This Week's Sky at a Glance, June 24 – July 2 appeared first on Sky & Telescope.

  • Solar System Gets its Ducks in a Row
    by Bob King on June 20, 2022 at 12:00 pm

    We'll have not one but many opportunities to enjoy a rare lineup of the bright planets over the next few weeks. Amazingly, they'll be aligned in order of their distance from the Sun. The post Solar System Gets its Ducks in a Row appeared first on Sky & Telescope.

  • This Week's Sky at a Glance, June 17 – 25
    by Alan MacRobert on June 17, 2022 at 9:07 am

    The five naked-eye planets form a diagonal line in the dawn this week — in order of their distance from the Sun, no less. And the waning Moon visits each one in turn, day by day. The post This Week's Sky at a Glance, June 17 – 25 appeared first on Sky & Telescope.

    by Alan MacRobert on June 10, 2022 at 9:09 am

    The waxing gibbous Moon shines with Spica, then occults Delta Scorpii. Meanwhile, all seven planets other than Earth are forming into a diagonal line across the east to southeast at dawn. The post This Week's Sky at a Glance, June 10 – 18 appeared first on Sky & Telescope.

    on June 22, 2022 at 2:14 pm

    A team has used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a 'gap' in the various wavelengths used to observe this icy water world. The team's near-global UV maps show concentrations of sulfur dioxide on Europa's trailing side.

    Astronomers identify a new class of stellar system. They're not quite galaxies and only exist in isolation.

  • Watching the death of a rare giant star
    on June 16, 2022 at 6:43 pm

    Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. By tracing molecular emissions in the outflows around the red hypergiant star VY Canis Majoris, astronomers obtained the first detailed map of the star's envelope, which sheds light on the mechanisms involved in the final stages of extreme supergiant star.

    on June 16, 2022 at 1:13 am

    The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind -- known as a white dwarf -- is sucking in debris from both the system's inner and outer reaches, astronomers report.

    In the American Wild West, high noon was a time for duels and showdowns. When it comes to the history of the universe, cosmic noon featured fireworks of a different sort. Some 2 to 3 billion years after the big bang most galaxies went through a growth spurt, forming stars at a rate hundreds of times higher than we see in our own galaxy, the Milky Way, today. When it launches by May 2027, NASA's Nancy Grace Roman Space Telescope promises to bring new insights into the heyday of star formation.

  • Image: Hubble captures a galactic menagerie

    on June 24, 2022 at 3:16 pm

    The supermassive black hole (SMBH) at our galaxy's core, Sagittarius A*, is modest in size with only 4.15 million solar-masses. The Event Horizon Telescope (EHT) recently released a dramatic submillimeter image of it as seen illuminated by its glowing environment. Many galaxies have nuclear SMBHs that are a thousand times bigger, for example the nucleus of M87, whose image was taken by the EHT in 2020. But SagA* is relatively close to us, only about twenty-five thousand light-years, and its […]

    When asteroid 2019 OK suddenly appeared barreling toward Earth on July 25, 2019, Luisa Fernanda Zambrano-Marin and the team at the Arecibo Observatory in Puerto Rico jumped into action.

  • The star that survived a supernova
    on June 23, 2022 at 7:33 pm

    A supernova is the catastrophic explosion of a star. Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind. At least that's what models and observations suggested.
