Scientists Report a ‘Flash’ Occurred When Two Black Holes Collided

Even people who are not deep into science are familiar with the fact that black holes do not produce light and, instead, they do the opposite – black holes have such a strong gravitational field, that even light particles cannot escape it. However, observatories and laboratories around the world recently caught a flash of light coming from the most unlikely place – the collision of two small black holes. 

One of the first observatories to have caught a glimpse of the event is the Zwicky Transient Facility. But how did they know what caused this? Weeks before this, the Earth’s gravitational wave detectors in other laboratories revealed that two massive objects had collided at such a scale that they sent ripples throughout space. Upon further analysis, it was discovered that both events came from a nearly identical region of the sky, and many scientists now share the opinion that the two events might be related.

Danien Stern, a renowned astrophysicist in the California-based NASA Jet Propulsion Laboratory, stated that ‘There’s a lot we can learn about these two merging black holes and the environment they were in based on this signal that they sort of inadvertently created.‘
