'Seeing' black holes with the naked eye

more »
All you need is a 20 cm telescope to observe a nearby, active black hole. An international research team reports that the activity of black holes can be observed as visible light during outbursts, and that flickering light emerging from gases surrounding black holes is a direct indicator of this. New results indicate that optical rays and not just X-rays provide reliable observational data for black hole activity.
