Springer 587-709-3976 Author John Stephen Hicks has updated his seminal book Building a Roll-Off Roof or Dome Observatory; A Complete Guide for Design and Construction, Second Edition (paperback: $34.99; ebook: $19.99). Hicks discusses each aspect of backyard observatory design and construction to help you decide which type suits your needs best. Important considerations including structural variations, placement, and zoning and bylaw requirements common to most states and municipalities are discussed at length. Step-by-step directions and detailed diagrams are included for each phase of construction. 248 pages, ISBN 978-1-4939-3010-4. SkyandTelescope.com's New Product Showcase is a reader service featuring innovative equipment and software of interest to amateur astronomers. The descriptions are based largely on information supplied by the manufacturers or distributors. Sky & Telescope assumes no responsibility for the accuracy of vendors statements.

Would float in a bathtubNASA/ESA/G. Bacon (STScI) By Shannon HallA star’s heat goes deep. For the first time, we have spotted a “hot Jupiter” that has expanded thanks to its swelling host star – an observation that could settle a 15-year-old debate. Hot Jupiters – gas giant exoplanets that orbit scorchingly close to their stars – are inexplicably puffy. “We see these planets that are the sizes of stars without being anywhere near the mass of those stars,” says Sam Grunblatt at the University of Hawaii. HAT-P-1b, for example, contains half the mass of Jupiter yet is 20 per cent larger in radius. This gives it such a low density that it would float in a bathtub. For more than a decade, we have been trying to explain how these planetary puffballs grow so large. The dozen or so different scenarios we have come up with all fall into two broad categories: either the star’s heat keeps the planet from cooling and therefore contracting, or it somehow penetrates the planet’s deep interior, causing it to expand. Heat is gone One way to test this would be to nudge an older planet – one whose initial heat is long gone – ...

Imagine how Rosetta's descent might look if you were an observer at Comet 67P/C-G! This new animation visualises the final stages of Rosetta's descent to Comet 67P/Churyumov–Gerasimenko on 30 September 2016. The sequence is speeded up to show the relative motion of Rosetta and the rotating comet below. Earlier today, Rosetta completed a small manoeuvre as planned that puts it on the start of a 16 x 23 km orbit needed in preparation for the collision manoeuvre on 29 September. Recap the final trajectories in the below animation:
