WebThe Black Hole at the centre of Messier 87. Image from the EHT Consortium/ESO. Black holes are very strange objects. They are made during supernova explosions. These take place when very massive stars come to the end of their lives. After the supernova, anything left of the star is squashed and compacted into an incredibly small, dense object. Web29 okt. 2024 · Einstein’s theory of gravity says that when you squeeze it into a small enough region of space—with a size known as the Schwarzschild radius, RS ( M )—the object becomes a qualitatively new kind of beast, a black hole. A black hole is a clump of matter so dense that even light cannot escape its surface, or event horizon.

WebScientists think that black holes are created in places where matter gets extremely dense (where a huge amount of material is crammed into an extremely small space). This can happen in the centers of large galaxies or when a giant star collapses and shrinks during the final phases of its life. WebBlack holes can be surrounded by rings of gas and dust, called accretion disks, that emit light across many wavelengths, including X-rays. A supermassive black hole’s intense … WebFormed of three spacecraft flying in a triangular formation, LISA will help us explore the fundamental nature of gravity and black holes. Although XMM-Newton, Integral, Athena and Lisa are ESA’s most dedicated black hole missions, other missions are also contributing in big ways. phosphat funktion
