Climate from Space vs Galaxy Map

Satellites observing the Earth from space provide a clear picture of the health of our planet and the signs of climate change. This electronic book lets you take a closer look at the climate data being produced by the European Space Agency's Climate Change Initiative. Forty years of climate data are at your fingertips on interactive globes and maps. Use the data viewer to see how climate variables including ocean temperature, ice sheets, sea level, sea ice, carbon dioxide and soil moisture change through time. Play, pause, and step through the data; spin the world and zoom in; switch between globe and map views; compare one data set with another. Engaging and richly-illustrated text explains why measuring these parts of the Earth system is important for climate science, and describes what the climate data shows. Project scientists from across Europe explain their work in their own words in short video interviews. Features: • Interactive, animated globes with 17 key climate data sets • Scroll through time to see forty years of change • 130 illustrations, including satellite images, diagrams and animations • 14 interviews with project scientists • Over 16,000 words of text • 74 pages Requires: iPad 4th gen (2012), iPad mini 2 (2013), or later.

The galaxy map is an interactive map of the Milky Way galaxy, Andromeda and their satellite galaxies. Explore the Orion Arm's nebulae and supernovae from the comfort of your spaceship. Fly through the atmosphere of Mars and many other planets and you can even land on them. Discover the galaxy in a stunning three dimensional map based on NASA's artistic impression of the Milky Way galactic structure. Photos are taken by NASA spacecraft and ground based telescopes like Hubble Space Telescope, Chandra X-Ray, Herschel Space Observatory and the Spitzer Space Telescope. This interactive 3D map is excellent for teachers to use for instruction, and it is a great astronomy resource for students to explore the Milky Way galaxy and space as they learn more about the universe we live in. Available in over 100 languages! You can also From the outskirts of the galaxy, in the Norma-Outer spiral arm to the galactic center's supermassive black hole Sagittarius A*, discover a galaxy full of amazing facts. Notable structures included: the Pillars of Creation, Helix Nebula, the Engraved Hourglass Nebula, the Pleiades, the Orion Arm (where the solar system and the Earth are located) with its Orion belt. Check out neighboring dwarf galaxies such as Sagittarius and the Canis Major Overdensity, stellar streams as well as internal galactic components such as a variety of nebulae, star clusters or supernovae. Explore space and get a little closer to our wonderful universe with this awesome astronomy app! The Galaxy Map requires internet access to retrieve information from the wiki.
