Regex to get all character to the right of first space?

Question

I am trying to craft a regular expression that will match all characters after (but not including) the first space in a string.

Input text:

foo bar b

You don't need look behind.

my $str = 'now is the time';
# Non-greedily match up to the first space, and then get everything after in a group.
$str =~ /^.*? +(.+)/; 
my $right_of_space = $1; # Keep what is in the group in parens
print "[$right_of_space]\n";
