Are you looking for a different place to visit this summer? Why not take a magical trip to an Earth-size planet beyond our solar system with NASA's Planet Travel Center?
We live in a universe full of planets outside our solar system. Unluckily, even the nearest of those planets are light-years away, so sending spaceships and humans to these attracting worlds remains a distant dream. But on NASA's Planet Exploration website, you can start a journey on an imagined globe of a new world through 360-degree visualization(可视化). As you land onto each globe's ground, you'll discover amazing views, like the blood-red sky of TRAPPIST-1d, or stand on a moon of the huge planet Kepler-16b, which appears larger than either of the planet's two suns. The view from each planet's ground is an artist's impression based on the limited information that is reachable; no real photos of these planets exist.
The newest planet with such 360-degree visualization is Kepler-186f, an Earth-size planet rounding a star much cooler and redder than the Sun. “Kepler-186f is also so distant, and it is till now impossible to recognize their atmospheres—if they exist at all—or characterize their atmospheric qualities,” said Martin Still, scientist for NASA's newest space-based planet-hunting program, wondering people's reaction to their creation. “Though with such challenges unsettled, using the NASA visualization tool, you can see how the existence and disappearing of an atmosphere would change the view of the sky from the planet's ground.” Still added.
Aaron, head of Planet Travel Center, points out that their present and future schedules of the globe visualization will find the nearest planets to our solar system and characterize their atmospheres, bridging the gap between our imagination and what's really out there. In the near future, all the 360-degree visualizations are viewable on desktop and mobile devices, like smartphones, allowing all readers a wonderful enjoyment from the possibilities of a new world.
