When the Sun, Earth and moon are in alignment, what effect does it have on the tide?
The tide is larger than normal(spring tide) because the gravitational forces of the Sun and Moon pull in the same direction

How is a star born?
Stars start out in giant clouds of dust called nebulae. Gravity forces the dust to bunch together. As more and more dust bunches up, gravity gets stronger and it starts to get hot and becomes a protostar. Once the center gets hot enough, nuclear fusion will begin and a young star is born
