Supernovas
Both ways of this can result in a supernova.
What is star death
The sun can expand and affect these planets.
What is inner planets and earth
The supernova blast traveling at roughly 5% of light speed could destroy Earth in less than this time.
What is 3 hours
Supernovas are the most powerful and impressive events in the universe.
What is the universe
The closest star to Earth is not likely to explode in this way in the near future.
What is a supernova
Supernovas release amounts of this kind of radiation.
What are X-rays and gamma rays
What phase of the Sun expands enough to engulf the inner planets?
What is the red giant phase
A supernova in our galaxy would cause mass extinction on Earth by destroying this
What is the ozone layer
Supernovas are hard to observe from Earth because they can be this far away.
What is very far
In about 5 billion years the sun will enter this phase
What is the red giant phase
Stars of this size can become supernovas.
What is massive
The Sun’s explosion could vaporize the planet’s surface after it arrives.
What is radiation
The energy from a supernova could arrive before the shockwave in this many minutes.
What is 8 mintues
Supernovas outshine galaxies for a short period, making them this event.
What is bright
If a star exploded close by, life on Earth could be destroyed in this timeframe
What is hours
What would be destroyed if the closet star were to explode in a supernova?
What is the entire solar system
What would happen if the sun were to explode
What is the whole solar system would be dystroyed
A supernova in our galaxy could cause a a crazy amount of extinction on Earth by destroying this.
What is ozone layer
Supernovas can be difficult to observe from Earth because they can be this far away. (hint: think of distance)
What is very far
The Sun’s explosion is not likely to happen because it is not this.(hint: think of size)
What is not big or massive enough
