Lights that seemed to be stars in a formation of a triangle dimming out slowly one after the other.

i was taking the garbage out tonight and like i usually do after taking the garbage out to look up at the dusk sky to make a few prayers & to think to myself for about 10 min. i noticed what i thought to be stars as i was thinking/praying i noticed one of the lights to dim out slowly about 1/2 second then the next light dim out again within about 1/2 second then the third do the same, in a formation as what i could make out to be a triangle of three stars two at the top of formation and the one at the bottom making it out to be an upside down triangle from my point of view. after that happened i noticed what i could make out to be possibly a sattelite going quite fast in the direction where the dimming lights were, they looked relatively the same from eye vision but i know satelites travel some what fast & usually in a different direction from what i notice from looking up at the sky in our backyard.  I was amazed, and loved what i saw, still unsure what it could be.  My hopes are infact alien beings visiting us. <3
