Tantalising evidence has been uncovered for a mysterious. Earth-sized planets are difficult to detect and until recently, with discoveries from the Kepler space telescope, only a handful had been found (NASA.
The protostar stage, on the far left of this image, can be some 2000 times larger than our Sun. Kepler telescope glimpses population of free-floating planets.
This image is illustrative the ages, sizes, and colours are approximate (not to scale). By studying HIP 102152, we can get a glimpse of what the future holds for our Sun. The Sun is 4.6 billion years old and 18 Sco is 2.9 billion years old, while the oldest solar twin is some 8.2 billion years old - the oldest solar twin ever identified. Marked on the lower timeline are where our Sun and solar twins 18 Sco and HIP 102152 are in this life cycle. After spending the majority of its life in this stage, the star's core begins to gradually heat up, the star expands and becomes redder until it transforms into a red giant.įollowing this stage, the star will push its outer layers into the surrounding space to form an object known as a planetary nebula, while the core of the star itself will cool into a small, dense remnant called a white dwarf star.
