Stars are massive objects scattered across the night sky, capable of engulfing entire planetary systems.
Some stars are hundreds and thousands of light years away from Earth, while others are relatively close by cosmic standards.
Our journey starts with our own Sun, a typical yellow dwarf star.
We will explore nearby stars like Barnard's Star and Beetlejuice.
The journey will take us to massive supergiants, including CW Leonis and Stevenson 2-18, the largest known star in our galaxy.
What is the size of the Sun compared to other stars in the galaxy?
—The Sun is larger and brighter than 80% of all the stars in our galaxy.
What elements make up the Sun?
—The Sun is mainly composed of hydrogen and helium, with smaller amounts of other elements like carbon, oxygen, and nitrogen.
What is the purpose of the Parker Solar Probe?
—The Parker Solar Probe is designed to study the structure and dynamics of the Sun's magnetic fields, measure the energy flow emitted by the Sun, capture particles of solar wind, and observe wavelike processes in the Sun's corona.
What is Barnard's Star?
—Barnard's Star is a red dwarf star that is moving towards our solar system at a high speed. It will become our closest star in about 10,000 years.
What is the largest known star in our galaxy?
—The largest known star in our galaxy is Stevenson 2-18, a supergiant star capable of swallowing tens of millions of stars like our Sun.
