The top .gov websites by PageRank are the US agencies that other sites quote most: health and science agencies like the NIH and the CDC, consumer agencies like the FTC, and large state sites.
Only US government bodies can use .gov, so every domain here is official.

Why health agencies lead the top .gov websites
Health, science and news websites link to government data all the time: research, statistics, safety advice. Each of those links counts, so the agencies that publish the most useful data rise to the top.
Pages like these are also a good source when you write: linking to official data makes your own article more trustworthy for readers.

Frequently asked questions
Who can use a .gov domain?
Only US federal, state, local and tribal government bodies. Other countries use endings like .gov.uk or .go.id.
Can I get a backlink from a .gov site?
Only by being useful to them, for example as a cited resource. Buying a .gov link is not possible in an honest way.
Why is a state website so high?
Big state portals link out to thousands of local pages and get linked back by news sites, schools and businesses.
