Whenever we look at the sky, we wonder about the vastness of our universe. Even scientists have no idea about its full extent of its complexities. But they have estimated that there are about one hundred billion galaxies, and there are 100 billion stars in each of them. And, it’s so large that there are black holes that dwarf our sun by factors of billions, there are nebulae like as lyman-alpha blobs that are known as some of the largest objects in our universe. Well, the sheer vastness of it including undiscovered planets, mysterious moons, strange phenomena are almost incomprehensible to the human mind. So, our assignment help experts have provided this list to give you some interesting perspectives on our scientific measurement of stellar phenomena.
The largest known star
In 2012, it was discovered that the UT Scuti is the most massive star in the solar system, which is present in the constellation Scutum. Its radius is about 1.88*109 km. It has been estimated that it is about 5 billion times the volume of our sun. We can say that our sun would appear as a peanut when compared to this star. It is a variable star which means its temperature and brightness changes from time to time. Well, it tough to explore it further as it is 9600 light years away from our solar system.
Lowest temperature possible-The absolute zero
We all know that the lowest possible absolute zero is the lowest possible temperature which is equivalent to 0 Kelvin, an SI unit of temperature. Attaining this temperature is impossible. But recently, scientists have discovered that a boomerang nebula (a dying star) that is emitting the coldest gases ever recorded. And, they have assumed that its temperature is about -273 degree Celsius.
The largest moon in our solar system
There are eight planets in the solar system, and each of them has their satellites. Earlier it was thought that the largest moon in our solar system is that of our Saturn. But a few years ago, it was discovered that Ganymede, i.e., the moon of Jupiter is the largest one. Its diameter is 5,151 km.
Potentially habitable planets outside the solar system
In 2017, NASA discovered seven exoplanets that might have the ability to sustain life like earth. This system of seven planets named Trappist 1 is too close to each other. It is located 40 light years from earth. Interestingly, scientists earlier supposed that the Proxima Centauri could also support life potentially. But, later after analyzing its solar winds’ speed, it was found to be dead.
How many moons do our neighbors have?
You might be surprised to know that the number of moons of the planets present in the solar system depends on their distance from the sun. Mercury and Venus have no moon because they are too close to the sun. Mars has two- Phobos and Deimos. Jupiter has the highest number of them, i.e., 69 and Saturn has 62 that have complex orbits. The largest moon of Saturn is Titan, and the smallest one is Mimas. Uranus and Neptune have 27 and 13 satellites respectively. Neptune’s one moon is equivalent to the size of the planet Pluto itself.
These were some interesting but less known facts about our universe. If you found them interesting feel free share them with your folks. Well, there are a lot more than you can explore about the external space by going through the books and journals published by various universities around the world.
