Bright light travels across sky, dims, and flys into space.My 3 friends and I were hanging out around our firepit around 10:30 at night. We noticed a bright light in the sky, brighter than a plane. We didn’t see if the light just appeared or was traveling across horizon, but when we noticed it was really bright, just above the tree line in our backyard.The object was traveling in a southward direction across the sky, faster than a plane, and the light was getting brighter then suddenly dimmed and got dimmer and dimmer and finally disappeared out in space. What ever it was, this thing definitely left our atmosphere and went into space. The whole thing lasted around 3 minutes.
