  In 1997, van Hamme developed $p-$adic analogs, for primes $p$, of several
series which relate hypergeometric series to values of the gamma function,
originally studied by Ramanujan. These analogs relate truncated sums of
hypergeometric series to values of the $p-$adic gamma function, and are called
Ramanujan type supercongruences. In all, van Hamme conjectured 13 such
formulas, three of which were proved by van Hamme himself, and five others have
been proved recently using a wide range of methods. Here, we explore four of
the remaining five van Hamme supercongruences, revisit some of the proved ones,
and provide some extensions.
