What the new Gravitational Waves discovery means for the future of Astronomy

Washington Post - In August, for the first time ever, scientists witnessed the electromagnetic lightning and gravitational gusts from the stormy collision of two neutron stars in a distant galaxy. The cosmic cataclysm created a “kilonova” — a phenomenon that had never been seen before — and the observations by both traditional telescopes and gravitational wave detectors heralded a new era for science. In the years to come, astrophysicists will use two “messengers” to understand the universe: electromagnetism and gravity.

Something similar happened in radio wavelengths: The first radio signal from the jet didn't arrive on Earth until 16 days after the gravitational wave detection, according to Texas Tech University astronomer Alessandra Corsi, and it could linger in the sky for years.
