the Sun, is the solar system.

The word solar, originates from the latin word Sol, which refers to the sun. The Sun alone contains 99.8% of the total mass in the Solar System. And most of the remaining 0.2% comprises of Jupiter. That just goes to show how insignificant we are! One day, the Sun will consume Earth itself. Fret not! The day that happens will be about 7.5 billion years away. The Sun is classified as a yellow dwarf star, which sounds pretty cute. Some estimates for stars similar to the Sun in the Milky Way galaxy alone are as high as 7 billion. If this number is correct, there could be over one trillion stars that are roughly the same as our Sun in the universe.

Twinkle, twinkle, little star, How I wonder what you are. Up above the world so high, Like a diamond in the sky. 🌟 The final stages of a star’s life allow us a glimpse into the future of our own solar system. This image from our Hubble Space Telescope shows what’s left of a star 10,000 light-years from Earth.

A star like our Sun will, at the end of its life, transform into a red giant. The core of the star will eventually collapse in on itself, ejecting the surface layers outward. After that, all that remains of the star is what we see here: glowing outer layers surrounding a white dwarf star. In just a few thousand years they will have dissipated, and all that will be left to see is the dimly glowing white dwarf. More on this image, here.

Say hello to globular cluster 47 Tucanae 👋

This glittery spray of ancient stars is about 16,700 light-years away from Earth toward the constellation Tucana. Globular clusters like this one are isolated star cities, home to hundreds of thousands of stars that are held together by their mutual gravity. And like the fast pace of cities, there’s plenty of action in these stellar metropolises. The stars are in constant motion, orbiting around the cluster’s center.

Past observations have shown that the heavyweight stars tend to crowd into the “downtown” core area, while lightweight stars reside in the less populated suburbs. But as heavyweight stars age, they rapidly lose mass, cool down and shut off their nuclear furnaces. After the purge, only the stars’ bright, superhot cores – called white dwarfs – remain. This weight loss program causes the now lighter-weight white dwarfs to be nudged out of the downtown area through gravitational interactions with heftier stars.

Until these Hubble observations, astronomers had never seen the dynamic conveyor belt in action. The Hubble results reveal young white dwarfs amid their leisurely 40-million-year exodus from the bustling center of the cluster.
