Which technological advance has helped scientists to search for life in other star systems?

Scientists are developing techniques to detect signatures from space in their search for alien life.

The Very Large Array (VLA) telescope, at the National Radio Astronomy Observatory (NARO) site in Socorro, New Mexico, will be used to constantly seek evidence of technosignatures.

Hope this helps

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
