This Tuesday we went to the planetarium to see the life cycle of a star. We also learned about constellations. We learned about Orion, the Horse Head nebula, and the star Sirius. The life cycle of a star is: a nebula, then a main sequence star, then a red giant, then a planetary nebula, then white dwarf, and finally a black dwarf. That about sums it up for this week. If you get a chance I recommend the planetarium. Tucker.
