The Sun is currently in its main-sequence phase, fusing hydrogen into helium in its core. This is the longest and most stable phase of a star's life.

Meanwhile, thought Id revive my science posting again.
Today I wanna talk about 55 Cancri! Its a binary system consisting of star A (Copernicus), a K0IV–V type mainsequence subgiant, and star B (no prpoper name afaik), a M4.5V type mainsequence red dwarf

Zeidler and collaborators found the first brown dwarf candidates outside of the Milky Way. Brown dwarfs are objects that are less massive than stars but more massive than planets.

Two-pannel illustration from a scientific paper, showing a black and white, inverted JWST image of the area around the star cluster NGC 602. Circled are the control field in blue, an area to the left of the cluster, and the cluster region in black, an area centered on the main star cluster. Plotted on top are the spatial distribution of the Pre-Mainsequence (PMS) stars and candidate Brown Dwarfs (cBDs, upper panel), and the candidate Young Stellar Objects (cYSOs, lower panel). The PMS stars and the cBDs follow the same spatial distribution, concentrated in the cluster region and trailing off to the left. The cYSOs are mainly located on the gas and dust ridges surrounding the cluster. A scale bar marks 35 arcseconds or 10 parsecs, which is about 1/8 of the width of the image.

The "main sequence" on the Hertzsprung-Russell diagram represents the stage of a star's life where it is primarily fusing hydrogen into helium in its core. #MainSequence #HertzsprungRussellDiagram #HydrogenFusion

M55: Color Magnitude Diagram

Color-Magnitude Diagram (CMD) of globular cluster M55. Each dot represents a star, its color indicating temperature (red=cool, blue=hot), and position showing brightness and color index (B-V). The diagram reveals distinct stellar populations: main sequence, red giant branch, and blue giants, illustrating stellar evolution and cluster age.
