Hace 1 día · In summary, stars are formed through fascinating stages, starting from a nebula and ending as stabilization. Each stage plays a crucial role in the star’s development and eventual fate. By understanding these stages, we gain insight into the life cycle of stars and the incredible processes that shape our universe.
Hace 4 días · A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the progenitor, either collapses to a neutron star or black hole, or is completely destroyed to form a diffuse nebula.

Hace 4 días · A visible light image of the Andromeda Galaxy. Messier 32 is to the left of the galactic nucleus and Messier 110 is at the bottom right. The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224.
Hace 2 días · The nova will appear in the constellation Corona Borealis, or “northern crown,” which is located between the Hercules and Boötes constellations. This part of the sky should be visible from most places on Earth except for the far south, close to Antarctica. The nova won’t look like an explosion, but like a new star that wasn’t there before.
Hace 2 días · For the Sun, four thermal pulses are predicted before it completely loses its outer envelope and starts to make a planetary nebula. By the end of that phase—lasting approximately 500,000 years—the Sun will only have about half of its current mass. [citation needed] The post-asymptotic-giant-branch evolution is even faster.
