Exoplanets are planets orbiting stars beyond our own solar system. This app allows you to explore all discovered exoplanets, their measured physical properties, their location in the night sky, and their host stars. An interactive model shows you the entire observable universe, all the way from the surface of the Earth to the cosmic microwave background. This app has been developed by a professional astronomer. Main features: * Interactive visualizations and animations. * Physical properties of all detected exoplanets and their host stars, updated on a daily basis. * Stunning 3D model of our Milky Way showing the location of all known exoplanets. You can zoom into any planetary system, explore how the night sky and the constellations look from the surface of other planets, or zoom out and see other local galaxies and galaxy clusters as well as the cosmic microwave background. * Visualizations of exoplanet orbits and the habitable zone. * Choose between the Open Exoplanet Catalogue, the NASA Exoplanet Archive, and the Extrasolar Planet Encyclopedia (exoplanet.eu). * Push notifications are sent out whenever a new planet is discovered. * Augmented reality sky map: point the phone towards the sky to find an exoplanet! * Interactive multi-touch correlation plots. * Solar System planets, major moons, and asteroids are included. * Explore S-Stars orbiting the black hole at the Galactic Center of our Milky Way * Background information about exoplanets and detection methods. * Full support of planets in binary, triple, quadruple systems and orphan planets. * Real-time ray tracing on the GPU.

"AGILE: from Black Holes to the Earth" AGILE is a satellite of the Italian Space Agency (ASI) dedicated to unveiling the most exciting mysteries of our Universe. Black holes, neutron stars, stellar explosions, very far galaxies from deep space and other exotic cosmic sources emit very energetic radiation (gamma-rays) that AGILE is able to detect in orbit. Launched in 2007, the satellite is currently observing the Universe with many surprises and crucial discoveries. AGILE contributes also to the study of the Earth having detected hundreds of "terrestrial gamma-ray flashes" associated with lighnting in energetic thunderstorms. Their impact for the environment is under study. Thus, AGILE reaches the frontiers of our knowledge for both the remote cosmos and our planet Earth, a very important synergy for our society. The AGILE project is the result of the collaboration between ASI, the Italian Institute of Astrophysics (INAF), and the Italian Institute of Nuclear Physics (INFN). Several Italian universities participate in the program (Rome-1, Rome-2, Trieste, Pavia), as well as space companies including CGS, Oerlikon-Contraves, Thales-Alenia Space (ex Laben), Galileo Avionica, and Mipot. This APP presents an overview of the AGILE exciting results: it is a window for exploring the most energetic phenomena of our Universe. Developed by Nicolò Parmiggiani (Università di Modena e Reggio) in collaboration with INAF/IASF Bologna the AGILE App features different tabs: 1) NEWS: the most important news related to the AGILE space mission. 2) GALLERY: a collection of videos of the main discoveries, of photos of the satellite construction and launch campaign, and of maps showing the gamma-ray universe as seen by AGILE. 3) TOP: the most important scientific discoveries. 4) MORE: including the following sections: 4.1) Position: AGILE location in orbit (displayed in real-time). 4.2) ATEL/GCN: the complete list of the AGILE Astronomical Telegrams and GCN Circulars. 4.3) AT reserved section.

Verdict

The call

The clearest difference is in-app purchases: AGILEScience at none against Exoplanet's 7. AGILEScience also leads on review sentiment (100% vs 91%) and iOS requirement (8.0 vs 13.0). Exoplanet's advantage is update cadence (every 2 weeks vs every 3 months) and device support (4 vs 2). On price and ads there is nothing between them.
