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.
Hydrogen is the most common element (around 90% of the universe's atoms are hydrogen). However, in order for stars to form, there must be enough hydrogen present in an interstellar cloud fragment for nuclear fusion to start - too little mass and you end up with a brown dwarf, sometimes called a failed star.
