Mini-Jet Found Near Milky Way’s Supermassive Black Hole

The video discusses a supermassive black hole in the Milky Way, over 4 million times the mass of the sun, which shows signs of past activity through jets and radiation. NASA's Hubble Space Telescope has provided evidence of these jets interacting with hydrogen clouds, creating expanding bubbles. Historical outbursts have been powerful enough to illuminate distant gas structures like the Magellanic stream. Future activity could result in a spectacular display.

What evidence suggests that the supermassive black hole is not dormant?

• The size of the black hole

• The color of the hydrogen cloud

• The presence of a blowtorch-like jet

• The black hole's mass compared to the sun

What happens when the black hole 'hiccups'?

• It absorbs all nearby stars

• It stops emitting radiation

• It emits narrow beams or jets

• It changes its spin axis

How far do the expanding bubbles created by the jet extend?

• 100 light years

• 500 light years

• 1000 light years

• 2000 light years

What did Hubble observe in galaxy NGC 1068?

• A similar jet scenario as in the Milky Way

• A dormant black hole

• A supernova explosion

• A new star formation

What is the Magellanic stream?

• A new galaxy

• A stream of stars

• A glowing gaseous structure

• A black hole remnant
