Michio Kaku is professor of theoretical physics at City College New York. He is a best-selling author and TV presenter. Two of his most recent programs were shown on BBC Four and his latest book Physics of the Impossible (Allan Lane) is on sale now. Astronomy Now's Kulvinder Singh Chadha talks to the man who dreams about the impossible.
This 132-page special edition features the ultimate observing guide for 2009, a review of all the biggest news stories of 2008, in depth articles covering all aspects of astronomy and space missions for 2009, previews of International Year of Astronomy events and much, much more. 
A 100-page special edition from the creators of Astronomy Now magazine, The Grand Tour of the Universe takes readers from one end of the Universe to the other and, in doing so, asks the question "just how big is the Universe?"
This special publication features the photography of British astro-imager Nik Szymanek and covers a range of photographic methods from basic to advanced. Beautiful pictures of the night sky can be obtained with a simple camera and tripod before tackling more difficult projects, such as guided astrophotography through the telescope and CCD imaging.
Astronomy Now presents
this 100-page, full-colour guide to the 68 constellations visible from the British
Isles by Neil Bone, the respected amateur astronomer and writer.
Astronomy Now is pleased to announce the publication of Exploring Mars. The very best images of Mars taken by orbiting spacecraft and NASA's Spirit and Opportunity rovers fill up the 98 glossy pages of this special edition!
