Sky & Telescope July 2016Mysteries Revealed: Juno at Jupiter, Aquila's Nebulae, and Fast Radio Bursts

Jupiter greets us with a familiar, friendly face at the telescope at night, but it hides secrets inside — and this July, NASA's Juno spacecraft will arrive at the king of planets to reveal those mysteries from its unique vantage point. Mysterious fast radio bursts have secrets to reveal, too. Once relegated to the scientific fringe, a multitude of discoveries  have put these enigmatic flashes of radio waves back under the spotlight — read the issue to see what we know. And there are no secrets deeper than those of the sky: look into Aquila's absorption nebulae this summer with a guide from Richard P. Wilds. Plus, get tips on the astrophotography software DeepSkyStacker, watch the planets all night long, and take the Pluto challenge.
