Supernovae are fascinating because they are some of the most powerful and destructive events in the universe. They are the explosive deaths of massive stars and can release as much energy as the sun will produce over its entire lifetime in just a few seconds. They are also very rare, occurring only a few times in a galaxy per century.
The bright explosion of a supernova can outshine an entire galaxy for a short period of time, and the remnants of the explosion can be studied for many years afterward to learn more about the life and death of stars.
Astronomers detected two interstellar meteorites, and they’re unusually strong
According to NewScientist, the two meteorites coming from other solar systems that have been discovered so far are so unique that they made scientists think deeper about their possible origin. They have concluded that a supernova might be to blame for producing the meteorites.
Interstellar meteorites are cosmically cool space rocks that have traveled from other star systems and landed on Earth. These extraterrestrial travelers are the ultimate party crashers, showing up uninvited from the depths of the galaxy and making themselves at home on our planet.
But don’t worry, they’re not here to cause any trouble (at least not on purpose). In fact, these space rocks are actually pretty timid and shy, preferring to spend their time quietly plying the intergalactic seas, minding their own business.
Supernovae are also responsible for producing many of the heavier elements in the universe, such as iron, nickel, and cobalt. These elements are formed through a process called nuclear fusion, which occurs when the temperatures and pressures within the star are high enough to bring atomic nuclei close enough together to fuse. When a star goes supernova, the explosion and shockwaves create even higher temperatures and pressures, allowing for the formation of even heavier elements.
In other words, we weren’t here if stars never go ‘boom.’
