From this March, DS owners in Japan will be able to navigate the night skies, thanks to astronomy magazine publisher Astroarts. Hoshizora Navi (Starry Sky Navigator) was first revealed in March 2008, but now an official site has opened, rich with details.

Apparently, the software comes packed with star charts containing 9,300 stars, the sun, planets, the moon, various constellations, and assorted meteor groups. Also, budding astronomers will be able to view the night sky at any point between 1900 and 2099, and even stargaze from several viewing locations across the globe. To help you differentiate between your Apastron and your Aphelion, there's an onboard astronomical dictionary of more than 400 terms.

But allow us to remind you of the best bit: the Hoshizora Navi cartridge will come with a built-in positional sensor, meaning that as your DS moves, so does the view on your screen, to match your own! It's undoubtedly very clever, even though the tech has clearly pushed the price sky-high -- Hoshizora Navi goes on sale on March 26 for ¥8,190 (around $90)!
