WorldWide Telescope (WWT) was a research project to visualize astronomical and other 3D data developed by Microsoft. The software is released to third parties to develop it further.
Users can navigate through the starry sky as seen from the Earth, explore its objects, travel across the solar system, and tour the universe in three dimensions. The database ranges from satellite images providing a detailed view of Earth to the solar system to the cosmic microwave background. Use WWT to visualize Earth‘s surface in marvellous 3D detail with its physical features, or in a cartographic mode. Fly over the trough faults and craters of Mars, or explore the maria and highlands of the Moon. As a strong point, WWT allows the positionally accurate integration of sky photographs taken through professional telescopes.
The application is integrated in powerdome and can be controlled with the ShowManager und powerdome Control. Start a tour with just a click in the Web interface.
WWT for multichannel projection
Although in principle it can be played on domes with multichannel projection systems, WWT has made it into few planetariums so far. This is on account of the software’s structure, which lacks some mechanisms that are essential for visually appealing multichannel performance. Also, it is flawed in many places. To make WWT really useful for planetariums, ZEISS has spared no effort to revise the software. The modified version – called “WorldWideTelescope for powerdome” – can now be used with our multichannel projection systems.
Cluster and desktop versions for powerdome
“WorldWide Telescope for powerdome” is available in two versions: a cluster version for presentations on the planetarium dome, and a desk-top version for free use.
It is in the nature of an open-source software to have bugs. The use of WWT for multichannel fulldome systems is governed by special requirements, which the freely available original version satisfies but insufficiently. ZEISS has made many corrections, optimizations and adaptations to the software to enable fairly smooth multichannel performance. Using this version is subject to license.
The desk-top version has the same scope of functions and is freely available (for download, see the margin column). Use this version to prepare live presentations and create tours you can later present in the planetarium with the cluster version. Give high-school students and hobby astronomers the possibility to develop shows with WWT off-line and to present them on the planetarium dome.
Modes for specific presentations
Get Mars or the Moon to the center of the image, and navigate closely to its surface. Load one of the photographic panoramas and transport your viewers to extraterrestrial landscapes. Let WWT for powerdome take you to planets or their natural satellites, observe the shadows of Jupiter’s moons, and find out where the majority of asteroids are located in the solar system.
Tours and dome renderer
The new powerdome release comes with an updated set of deep-sky objects including all Messier objects. We are grateful for the tremendous help of the Laupheim Planetarium under the guidance of Werner Kiesle to incorporate images which appear consistent with how the objects look best to the eyes of planetarium experts and visitors. Even more, Thomas Thuchan of the Laupheim Planetarium Association contributed 27 of his own excellent photographs of Messier objects to the new deep-sky catalog. All objects are permanently aligned to the star field. You can easily zoom into any of the objects using fingertip control in the powerdome control web interface. The objects can be presented as they would appear to the naked eye or they can also be excluded from the star field.
galaxies are about 50 million light-years distant, but M64 lies a mere 17 million light-years away.
My first sighting of noctilucent clouds this season, on the night of June 23/24, 2017 at 12:45 am in a display that lasted about an hour before the lighting angles from the Sun dropped and failed to light the clouds. This was from southern Alberta at a latitude of 51° N, with a 135mm telephoto lens 4 seconds at f/2 and ISO 800. Capella is the bright star at right of centre. Through the display a faint green aurora danced behind the clouds.
