The Sun is incredibly dynamic — something that's difficult to convey properly in the pages of a book or magazine. If you watch a major solar flare through a telescope, it will often change from one minute to the next. Time-lapse movies compress the time scale, allowing you to see this motion directly. In...
Due to the vast distances separating deep-sky objects from Earth, few show obvious changes on scales shorter than a human lifetime. But there are exceptions. When stars explode or flair, their energy and/or cast-off material can create changes visible thousands of light-years away. For instance, the star V838 Monocerotis flared in 2002. The flash...
In the article "Moving Pictures" from SkyWatch 2012, Lorenzo Comolli and Alessandro Gambaro explain in detail how to create time-lapse movies of the sky and other night scenes with a digital camera. Some of the authors' best videos are available on their website (click on AstroVideos in the left margin). Time-lapse skyscape videos have...
Planets change greatly in appearance over time frames ranging from hours to months. That's both due to superficial effects — rotation revealing different sides of a globe — and fundamental changes on a planet's surface or in its atmosphere. A number of amateur astrophotographers have stitched their own images together to create movies showing...
