< Liquids/Liquid objects | Astronomy

Liquid-object astronomy is a lecture and an article about a specific type of astronomical object and the techniques needed to observe it.

The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids. Credit: José Manuel Suárez.

6 Why is much of the surface of Mars covered with red iron oxide dust when the rocks that compose much of its surface are blue or violet?

Mars has been systematically bombarded with small iron-nickel meteorites or micrometeorites that oxidize in its atmosphere
Mars has been frequently bombarded with hematite containing micrometeorites
asteroid impacts on Mars may have forced iron from near its core into the atmosphere and onto the surface as hematite dust that oxidized
Mars is like Earth in surface hematite composition, but Earth has much more water
precipitation from iron-rich water
