NASA recently released a ‘star-studded’ view of the Milky Way galaxy.
The image was captured when NASA/ESA’s Hubble Space Telescope pointed its cameras towards the constellation of Sagittarius.
Blue stars can be seen scattered across the frame, set against a distant backdrop of red-hued cosmic companions.
According to NASA, the colour of a star can reveal many of its secrets. Shades of red indicate a star much cooler than the sun, so either at the end of its life, or much less massive. These lower-mass stars are called red dwarfs and are thought to be the most common type of star in the Milky Way.
Similarly, brilliant blue hues indicate hot, young, or massive stars, many times the mass of the sun.
“A star’s mass decides its fate; more massive stars burn brightly over a short lifespan,
and die young after only tens of millions of years. Stars like the sun typically have more
sedentary lifestyles and live longer, burning for approximately ten billion years. Smaller
stars, on the other hand, live life in the slow lane and are predicted to exist for trillions
of years, well beyond the current age of the universe, NASA wrote in a release.
