8 Cool Destinations That Future Mars Tourists Could Explore

Mars is a planet of vast contrasts — huge volcanoes, deep canyons, and craters that may or may not host running water. It will be an amazing location for future tourists to explore, once we put the first Red Planet colonies into motion. The landing sites for these future missions will likely need to be flat plains for safety and practical reasons, but perhaps they could land within a few days’ drive of some more interesting geology. Here are some locations that future Martians could visit.


Betelgeuse’s mysterious ‘Great Dimming’ may have been triggered by a wandering black hole

In late 2019, the star Betelgeuse dimmed by about 60%. While it’s impossible to say with certainty exactly what caused it, new research suggests that a wandering companion may have played a role. By swinging close to the giant star, the interloper may have raised a tidal bulge, causing the surface of Betelgeuse to dim. While this scenario can’t explain the full amount of dimming observed, it may have triggered other effects on the star that made the problem worse, researchers propose in a new paper.


Missing planets twice Earth’s size may point to migrating worlds

Exoplanets can come in a variety of sizes and masses. If you were to plot on a graph how many planets of each size astronomers have discovered, you’d find two peaks: one at 1.4 times Earth’s radius, and another at 2.4 times Earth’s radius. Between them is a dip or valley, at around 1.8 times the radius of Earth, signifying the relative scarcity of planets of that size.
