NASA Offers New Understanding of Black Holes

According to NASA, something very exciting that is going on this month is the NuSTAR probe. This probe has an ultra fast telescope that can detect black holes in a way which has been helpful in calculating their size.

A black hole is a mysterious entity that absorbs energy, and contains it. This energy can be any type of matter, from stars to light. The gravitational force is so strong that nothing can escape it. Sometimes, though, black holes eject a form of matter called plasma. These jets of hot gas radiate light and form two bright columns on black hole’s axis of rotation. This plasma is called an acceleration disk. How this is able to get enough energy to radiate light has been debated for centuries.

The amount of brightness a black hole emits through its jet is a sign of the amount of x-rays it is giving off. The x-rays originate from material very close to the center of the black hole. Strong magnetic fields propel the matter in a jet. The resulting particles collide at near light-speed, and this radiation can be detected by the ultra fast telescope.

This can be made into a theory, relating black hole sizes and their jets. This can contribute to scientists’ understanding of supermassive black holes. A supermassive black hole named BL Lacertae, is about 200 times the mass of our sun. The jets of this can be seen as proportionate to the prior smaller black holes and their jets.

Hopefully, we will be able to have a deeper understanding of these mysterious black holes and have a unifying theory for the size of the black-hole and their jet stream power.
