Latest Space Finding: Jets in our Supermassive Black Hole

Do not mistake these jets as a type of plane that we can see flying through Earth’s skies. In this case, the term “jet” refers to high-energy particles that can be found in space. Categorized under a branch of scientific study, called particle physics, these jets are believed to be produced when materials that were originally falling towards a black hole are redirected outwards. In fact, this amazing occurrence plays an important role in transporting energy and regulating the rate of new star formations.

Why is finding a jet so important to scientists? It helps them determine the direction of the black hole’s spin axis, which allows them to make more accurate assumptions about the growth and history of the black hole. Since the study found that the black hole is pointing to the same direction as the Milky Way, astronomers are able to insinuate that gas and dust have migrated steadily into the black over instead of colliding with large galaxies.

Since the activity of the giant black hole has been relatively low over the past few hundred years, the jets surrounding appears to be weak. However, scientists speculate that the jet may brighten dramatically when the black hole starts consuming material more actively.

The Mystery of a Mega Black Hole Explosion

Have you and your blaster been keeping up with the latest space happenings? Scientists from the University of Sydney found that two million years ago, a gigantic black hole exploded at the center of our galaxy. The eruption was 100 million times more powerful than it is today, and it lit up a cloud that was 200,000 light years away. Those are some impressive numbers!

The evidence to support this astonishing finding comes from the Magellanic Stream, which is a strand of hydrogen gas that follows behind our galaxy’s neighboring galaxies, which are simply called the Large and Small Magellanic Clouds. The researchers have been noticing a peculiar glow shining from the Magellanic Stream, and realized that this glow is a record of the massive outburst of energy when the black hole exploded at the heart of our galaxy many years ago.

The area that envelops all the galaxy’s black holes is called Sagittarius A*, which emits all sorts of radiations. Flickers of flares will appear when small clouds of gas fall onto the hot disk matter that swirls around the black hole. Scientists knew that the galaxy’s stars cannot produce enough ultraviolet that caused the glow they found in the Magellanic Stream, therefore, it can only be explained by the black hole theory.

These black holes can switch on and off within a million years, and the researchers are quite certain that this sort of colossal explosion will happen again in the future.
