And this is how it looks

As you can see in the code of reference, each word starts with capital letter however, thats is not how it looks in the PDF. So how can I fix it ?

The unsrtnat bibliography style practices what's known as (English) sentence style while typesetting the contents of title fields: Only the very first letter of the entire field preserves capitalization; everything else gets converted to lowercase unless it's protected from BibTeX's gaze by getting encased in curly braces. Thus, do be sure to encase words such as Magellanic, Hubble, Atacama, DR4, and CDM in curly braces. — Mico, Oct 20 '20 at 17:40
I guess it depends on what you mean by "an easier way". IMNSHO, if you choose to use a bibliography style that employs sentence style, you shouldn't willy-nilly override that setting. However, if you absolutely cannot stand sentence style and are willing to incur the disdain (or even wrath) of the editorial staff of the journal(s) to which you submit your paper(s), simply encase the title field in double curly braces. E.g., title={{The Atacama Cosmology Telescope: DR4 Maps and Cosmological Parameters}},. I still think that sentence style is cool... — Mico, Oct 20 '20 at 19:02
