I am using the builtin DATEPART function to retrieve month, day and year from a date so I can pass it to the DATENAME function: Now that I have Month, Day, Year values individually, I pass it to my DATENAME to get the Weekname of the date I want: This returns an incorrect Day Name.
Leaving Main Life Sequence. When a massive star has expended all of its core hydrogen, this means that the gravitational forces pushing inward will overcome the fusion forces which had been pushing outward. The outer layers of the star will then compact inwards.
In the beginning of life of a star the star is entirely made up of Hydrogen. But as Hydrogen gains energy(kinetic), it fuses together to make Helium. Now, the Helium also combines to form other elements like Lithium, Carbon, Magnesium and so on, but once it reaches the Iron stage, it begins to die(as iron is most stable in nucleons vs binding energy graph).
