‘Unprecedented’ Topo Maps of the Moon

Data from the Lunar Reconnaissance Orbiter’s Lunar Orbiter Laser Altimeter (LOLA) is leading to “the most precise and complete map to date of the moon’s complex, heavily cratered landscape,” NASA said last week. The new LOLA maps are more…  •  Continue reading this entry.

Eclipse Maps

There are an awful lot of maps showing the path of solar eclipses. These maps are vital to eclipse chasers, who spend vast sums travelling to places where they can see one, and those slightly less insane who nevertheless…  •  Continue reading this entry.

The Known Universe

The Known Universe, a short film from the American Museum of Natural History, “shows the known universe as mapped through astronomical observations,” zooming out from the Himalayas to the Cosmic Microwave Background and back in again. Via Christian Junk….  •  Continue reading this entry.

New Maps of Pluto Show Seasonal Changes

NASA has released new maps of Pluto, taken by the Hubble Space Telescope’s Advanced Camera for Surveys. Even through the Hubble, everyone’s favourite Kuiper Belt Object is only a handful of pixels across, and the Hubble can only make…  •  Continue reading this entry.

Martian DTMs

High-resolution digital terrain models (DTMs) of the Martian surface, created from stereo images taken by the HiRISE camera aboard the Mars Reconnaissance Orbiter. The upshot is an extremely detailed topographic/terrain map of the Martian surface — think the Terrain…  •  Continue reading this entry.

A New Map of Mercury

Planetary Maps

I frequently post entries about mapping the other planets and moons in our solar system not just because I’m nuts about astronomy (though I am), but also because this is where maps of new places are coming from. Our own…  •  Continue reading this entry.

Mapping Triton

Triton, the largest moon of Neptune, was visited for the first and only time on August 25 and 26, 1989, when Voyager 2 hurtled past it. Since then, any maps of that moon were based on images taken from…  •  Continue reading this entry.
