Yes, deliberate messages have been sent into space. The first one was sent in 1974. It’s now almost 46 light-years out from earth.
Other nations, such as China and Russia, may be actively sending messages as well. China now has the biggest radio telescope in the world. It went online in 2018 and can send signals as well as receive.
Of course, we’ve been sending unintentional signals for over 100 years. Aliens may be able to detect them but they’re too weak to decipher. Even at Alpha Centauri they become too weak.
The Arecibo message may be detectable at 100 light years, however. Humans now have the ability to send decipherable messages out to about 400 light years.
