Answer 1

ANSWER: num 1 is black hole

Answer 2

Black holes, the remnants of massive stars, mark the dramatic end after a supernova. Main sequence stars, like our Sun, enjoy a stable phase fusing hydrogen. Neutron stars form from high-mass stars, while low-mass stars yield planetary nebulae and white dwarfs. Star-forming regions birth new stars, showcasing the diverse cosmic journey.

Letter J represents a black hole, which is the final stage of a very massive star that collapses under its own gravity after a supernova explosion.

Letters B and D represent stars on the main sequence, which is the longest and most stable phase of a star’s life, where it fuses hydrogen into helium in its core.

Letter L represents a neutron star, which is the dense remnant of a high mass star that has exploded as a supernova and compressed its core into a ball of neutrons.

Letter I represents a white dwarf, which is the hot and dim core of a low mass star that has shed its outer layers as a planetary nebula and no longer undergoes fusion.

Letter D represents a low mass star, which is a star that has less than about 8 times the mass of the sun and follows a different evolutionary path than a high mass star.

Letter C represents a planetary nebula, which is a cloud of gas and dust that is ejected from a low mass star as it becomes a white dwarf.

Letter M represents a star forming region of space, which is a dense and cold area of interstellar gas and dust where new stars are born.

Letter H represents a planetary nebula, which is the same as letter C.
