When you head outdoors tonight, take Sky & Telescope's podcast with you for a guided tour to the night sky. Learn what constellations are visible, find out where and when you'll see the planets, and catch each month's celestial highlights, from meteor showers to eclipses.
  1. A new study explores the impacts of stars that age past the main sequence and evolve into red giants on the planets orbiting around them by looking at the orbits of gas giants closely circling evolved stars.

    The post When Giant Planets Orbit Evolved Stars appeared first on Sky & Telescope.

  2. Catch up on this week in astronomy news with a trio of images: a pair of near-Earth asteroid twins, ground-based views that beat Hubble's, and the tumultuous galactic center.

    The post 60-Second Astro News: Must-See Images of the Week appeared first on Sky & Telescope.

  3. Over the past 18 months, astronomers have painstakingly tracked a dozen tiny moons that they found circling the giant planet Jupiter.

  4. Comet PanSTARRS (C/2017 S3) has erupted again! Now bright enough to see in binoculars, it might become a naked-eye object if it survives until perihelion.

    The post PanSTARRS Comet, Rocked by Outburst, Goes Green appeared first on Sky & Telescope.

  5. On the night of July 27, 2018, the longest total lunar eclipse for the next 105 years will be visible across parts of Europe, Africa, Asia and Australia. Six months later, on January 20, 2019, there will be the 'Great American' lunar eclipse, where totality is visible across all 50 states.

  7. There’s no hiding — changes in Earth’s atmosphere over the seasons are a dead giveaway to the fact that Earth hosts life. Now a new study explores whether we might use atmospheric seasonality like Earth’s to detect life on other planets. Looking for Change Most of the searches for life beyond our planet focus on identifying static biosignatures, like the presence of methane or large amounts of oxygen in an […]

  9. Hanging dramatically in the west during twilight next Sunday evening (July 15, 2018) will be a bright “star” and crescent: Venus and the Moon. The cosmic couple will be quite the eye-catcher if your sky is clear.
