A powerful explosion of a star Crossword Clue

The crossword clue "A powerful explosion of a star" with the answer "SUPERNOVA" refers to a spectacular astronomical event that occurs when a star undergoes a catastrophic explosion.

This phenomenon marks the end of a star's lifecycle, typically happening in massive stars that have exhausted their nuclear fuel. During a supernova, the star's outer layers are expelled into space, and the core collapses, resulting in an incredibly bright and energetic burst of light and radiation

The crossword clue "A powerful explosion of a star" with the answer "NOVA" refers to a type of stellar explosion that occurs on the surface of a white dwarf star in a binary system.

When a white dwarf accumulates a critical amount of matter from its companion star, a thermonuclear explosion can happen, causing a sudden and dramatic increase in brightness.

The crossword clue "A powerful explosion of a star" with the answer "CATASTROPHIC EXPLOSION" refers to the intense and dramatic end event of a star’s life cycle. This type of explosion is most commonly associated with a supernova, which is a stellar explosion that occurs when a star reaches the end of its life cycle.

In a supernova, the star’s core collapses under its own gravity, leading to a massive explosion that can outshine an entire galaxy for a short period. The term "catastrophic explosion" captures the immense energy and destructive force involved in these cosmic events, which can result in the creation of neutron stars or black holes, as well as dispersal of heavy elements into space.

The crossword clue "A powerful explosion of a star" with the answer "STARBURST" refers to a sudden and intense outburst of energy from a star. In astronomy, a "starburst" typically describes a phenomenon where a star undergoes a rapid and vigorous increase in brightness and energy output, often due to an underlying event such as a stellar explosion or the formation of new stars.

While not as specific as terms like "supernova," which denotes a precise type of stellar explosion, "starburst" can be used more broadly to describe the dramatic, energetic releases observed in various stellar phenomena.
