Sirius is currently estimated at around 230 million years old and with a star its size, it is believed that its total life will reach 1 billion years.
Why does the star Sirius flash different colors?
But the star Sirius shifts through every color of the rainbow. That effect is thanks to the same turbulence that bends starlight slightly and makes stars look like they’re twinkling in the first place. These air fluctuations bend different colors of light by different amounts, giving Sirius its multi-hued appearance.

Why is the ‘disco ball’ falling in space?
And now that the “disco ball” is in space, students are going to help again by monitoring Starshine 3 as it falls …. at first slowly, then later with greater haste back to Earth. Starshine 3 is falling because the atmosphere is dragging it down. The satellite is orbiting 470 km above Earth in a region scientists call the thermosphere.
Are the red and blue stars constant in the sky?

What does it mean when a star blinks multiple colors?
Note: The witness may have seen a bright star. The apparent blinking multi-colors can be due to atmospheric particulates scattering light which can show up as multiple colors especially through binoculars. This light scattering occurs more in celestial objects lower on the horizon (as is the situation with this sighting).

And, when you look at an object low in the sky, you’re looking through more atmosphere than when the same object is overhead. The atmosphere splits or “refracts” the star’s light, just as a prism splits sunlight.
