The American space agency NASA says a huge star explosion is expected to light up the night sky later this year. NASA describes it as a “once-in-a-lifetime” event.美国航天局NASA表示,预计今年晚些时候会有一次巨大的恒星爆炸,将照亮夜空。NASA将其描述为“一生一次”的事件。The event is known...
The supernova explosion is a very violent celestial event that usually occurs at the end of a star's life cycle. It releases so much energy which can even outshine entire galaxies for a short time. The "shock breakout" is the earliest electromagnetic radiation event following a supernova...
During the lifetime of our Milky Way galaxy, there have been something like 100 million supernova explosions, which have enriched the Galaxy with the oxygen we breathe, the iron in our cars, the calcium in our bones and the silicon in the rocks beneath our feet. These exploding stars also...

A supernova is a massive star explosion that occurs when a star burns through its fuel at the end of its lifespan, resulting in a brilliant burst of fiery plasma in vibrant colors radiating with the brightness of a hundred million suns. ...
On October 9, 2022, orbiting X-ray and γ-ray telescopes registered the most powerful explosion ever observed in the Universe—the GRB221009A γ-ray burst at a distance of 2.4 billion light years. The response of the Earth's ionosphere to this unique event was detected in the received ...
How to see the nova explosion The nova will appear in the constellation Corona Borealis, located between Hercules and Boötes.NASA The T CrB white dwarf is usually too dim to see from Earth with the naked eye. But at the peak of its explosion, it will ...
A nearby supernova (SN) explosion could have negatively influenced life on Earth, maybe even been responsible for mass extinctions. Mass extinction poses a significant extinction of numerous species on Earth, as recorded in the paleontologic, paleoclimat
They predict it will happen sometime between now and September 2024. The last nova happened in February 1946. "The way we know that it's going to happen soon is right before the last explosion in 1946, the system dimmed quite a bit, and that just happened," said Golay, who is ...
The meaning of SUPERNOVA is the explosion of a star in which the star may reach a maximum intrinsic luminosity one billion times that of the sun. Did you know?
