Gravity field near earth at 1,2 and A the curvature of the Earth is negligible at this scale, and the gravity force lines can be approximated as being parallel and pointing straight down to the center of the Earth. (Credit: SA 3.0)
Field lines drawn for a point mass using 24 field lines. The gravitational field can be represented using field lines. These run in the direction that a mass would be accelerated in initially. The object will not necessarily fall along the field lines, but the acceleration will always be in the direction of the field lines. The closer the field lines are together, the denser the gravitational field.(credit: SA 3.0)

An artist’s view of how quasars and BOAs work together to measure the expansion of the universe. Light from distant quasars is absorbed by gas, which is imprinted with a pattern of BOAs from the early universe.

The Kuiper belt is a region beyond Neptune that is full of comets, asteroids and other debris. It circles the solar system and has always been a little bit of a mystery as it is so far away and hard to explore.(Credit: Chris Dann)
