Piping it to cut -f 1 will give only the ami name :)

Might want to limit that to the Ubuntu Cloud account. Can also use sort_by in the query to get the most recent.

aws ec2 describe-images \
    --owners 099720109477 \
    --filters Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-* \
    --query 'sort_by(Images,&CreationDate)[-1].ImageId'
