Eclipse

When a planet, moon or other body enters the shadow of another. Therefore a solar eclipse is technically not an eclipse at all but an occultation of the Sun (see Occultation), or an eclipse of the Earth.

Herbig-Haro object

These are hot bright patches of gas in space where the impact of fast moving gas (probably from young stellar jets) on the surrounding medium creates a glowing bow shock.

Zodiac

Constellations that the Sun, Moon and major planets appear to pass through as the Earth moves along its orbit.
