T-Rex (NGC 602) Nebulae Ripples tend to move slower

Ripples tend to move slower than dunes

This intense heat loss is likely a result of the fine dust on Phobos' surface

Its most prominent feature is the 6-mile crater Stickney

but are particularly evident as a carpet of dark tubes on the right

some of which started landslides that left dark trails marking the steep slopes of giant craters

T-Rex (NGC 602) Nebulae Ripples tend to move slowerThe Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans. Modern astronomers are also interested in studying the SMC (and its cousin,
