Today, we know them to be not stars being born but stars in their death throes, and we call the event a supernova. (The earliest record of a possible supernova appears in a prehistoric rock carving from Kashmir, but no one knows what the carver called the event, if anything.) ...
If a very nearby star goes supernova, it can genetically alter or possibly even destroy life on Earth. Even a fairly distant one often leaves visible wreckage that makes us telescopically gawk at what very much resembles a disastrous event. On top of all that, the most common supernovae...
A supernova is the explosion that spells the end of a star's life cycle. As the star fades, the unstable core collapses in on itself and the result is...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer ...
Further study has shown that the supernova had some unusual properties. "Our observations and modeling show this to be a rather unusual event, to be better understood in terms of an object lying at the boundary between normal supernovae and gamma-ray bursts," Paolo Mazzali, an Italian ...
supernova would be spewed out in the form of neutrinos, which would vaporize everything on Earth before the shockwaves of the explosion even reach the planet. Fortunately, we'll never have to worry about such an event because the sun is not going to explode. Not now, not later, not ...
A mutually exclusive event is one wherein two events cannot happen at the same time (e.g. getting heads and tails in a single coin toss), a mutually inclusive event allows both events to occur in a single trial (e.g. drawing a card that is a spade and dr
Meaning "northern crown" in Latin, Corona Borealis is a semicircle of mostly dim stars that wouldn't catch your eye on most nights, but in 2025, it's set to become the center of attention for stargazers across the Northern Hemisphere in what could be the brightest nova event of a life...
(about 100 billion light years) by using further “standard candles” than Cepheids, most notably Type Ia supernovae (which are bright enough and predictable enough to be usable out to about 10 billion light years), the Tully-Fisher relation between the luminosity of a galaxy and its ...
A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun. As these stars burn the fuel...
What is the main source in the universe for the origin of hydrogen? a. primordial nucleosynthesis b. fusion in cores of low mass stars c. fusion in cores of high mass stars d. slow neutron capture in high mass stars e. rapid neutron capture in supernovae ...
