NASA defines a black hole as ““an astronomical object with a gravitational force so strong that nothing, not even light, can escape it.”. And, in the last hours, the Spitzer space telescopecommanded by the space agency, showed some shocking images where dust currents are observed heading to the heart of the Andromeda galaxy. As expected, it had a strong impact on both researchers and fans of this topic.
“Images captured by the telescope show streams of dust thousands of light years long flowing towards the black hole supermassive in the heart of the Andromeda galaxy“, explained, in technical terms, the NASA page regarding such a discovery that may modify future actions for research of the same nature.
Along the same lines, the US agency detailed: “These currents help explain how black holes, billions of times the mass of the sun, feed as they gobble up gas and dust. The material heats up before falling, creating a light show brighter than a galaxy full of stars”. To account for the magnitude of this object, NASA described this “supermassive” black hole as a “silent devourer of the universe.”
In turn, within a host of particularities that encompass this phenomenon, black holes themselves do not emit light despite their incredible size. “The little light they emit does not vary significantly in brightness and this suggests that they are consuming a small but constant stream of food.”said NASA in this regard.
Detected by matter (gas, dust and stars) surrounding it, astronomers can detect these supermassive black holes because a “accretion disk around it” which manifests itself in a kind of enormous vortex that spirals towards this object.
Within the same theme, NASA, at the beginning of May, showed with a virtual simulator what it would be like to fall into a black hole to gauge the public about these issues. With the help of a computer Discover in it Climate Simulation CenterGoddard scientists created an “adventurous” camera and gave details of the entire process.
“Destiny is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located in the center of our galaxy, the Milky Way. To simplify the complex calculations, the black hole does not rotate,” NASA explained in this regard.
“A flat, swirling cloud of hot, bright gas called an accretion disk surrounds the black hole and serves as a visual reference during the fall. The same goes for bright structures called photon rings, which form closer to the black hole from light that has orbited it one or more times“added the space agency about this experience that could have been possible thanks to constant advances in technology.
