What is an extraterrestrial sky?
Q: What is an extraterrestrial sky?
A: An extraterrestrial sky is a view of outer space from the surface of a planet (or related body in space) other than Earth.
Q: Which extraterrestrial sky has been directly observed and photographed by astronauts?
A: The only extraterrestrial sky that has been directly observed and photographed by astronauts is that of the Moon.
Q: How do extraterrestrial skies vary?
A: Extraterrestrial skies seem to vary because of a number of reasons, such as the atmosphere's density and chemical composition which can contribute to differences in color, opacity (including haze) and the presence of clouds. Astronomical objects may also be visible and can include natural satellites, rings, star systems and nebulas and other planetary system bodies.
Q: Can we simulate an appearance for skies that have not been directly or indirectly observed?
A: Yes, their appearance can be simulated based on known factors, such as the position of astronomical objects relative to the surface and atmospheric composition.
Q: What are some examples of astronomical objects that may be visible in an extraterrestrial sky?
A: Astronomical objects that may be visible in an extraterrestrial sky can include natural satellites, rings, star systems and nebulas and other planetary system bodies.
Q: Are there any planets besides Earth where we have seen photographs taken from its surface?
A: Yes, photographs have been taken from the surface of Venus, Mars and Titan by space probes designed to land on those surfaces.
