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. Our galaxy's center region is producing gamma rays, but astronomers are still debating whether pulsars or dark matter are the source. Three recent studies tackle the debate head-on.

  2. From its dynamic atmosphere to its hidden depths, the Juno spacecraft has Jupiter as never before — surprising NASA scientists with unexpected complexity.

    The post Juno: Surprises in First Science Results appeared first on Sky & Telescope.

  3. ASKAP, the Australian Square Kilometre Array Pathfinder has only had a 3.4-day pilot survey and has already found a fast radio burst!

  10. Want to take your eclipse-photography experience to the next level? Get tips on advanced techniques from Fred Espenak, a.k.a. "Mr. Eclipse," during S&T's live webinar on Tuesday, May 23rd. There are now just three months to go until August 21st's total eclipse of the Sun. And, like me, you're probably wondering how much time and energy to devote to capturing the very best images of the eclipse that you can. […]
