Title: What is the purpose of the script like RETURN PUSHDATA(36)(...)

What is the purpose of the script like RETURN PUSHDATA(36)(...)

The example is in here:
https://www.blockchain.com/btc/tx/63910fdfa84db96bd1f28fead4c32f97388d5368c10059d035aac3c5f72fcdc0



Actually, there are two outputs
DUP HASH160 PUSHDATA(20)[78ce48f88c94df3762da89dc8498205373a8ce6f] EQUALVERIFY CHECKSIG
and
RETURN PUSHDATA(36)[aa21a9ed9463ee420b10cbad1d997bfa132a89dc9ba3de04e7233e6e6954f1bc339ebb1a]



The strange point is the first output has 12.77303443 BTC, the second is 0 BTC.



There are two questions about this transaction.

1) How the coinbase could have more than 12.5 BTC?

2) What is the purpose of the RETURN PUSHDATA(36)(...), actually, in theory, this output can never be consumed by anyone, becuase there is no OP_CHECKSIG or similar OP at the end to return true in the Script stack.
