Random Riddle: From Icy Realms

I came long ago, from icy realms far;
I may have seen the newborn Superstar.
Giants reached out to grab me, as they say;
I turned aside, and there my pathway lay.

England’s King, in me a dark omen saw;
People watched me in horror, fear, and awe.
And as the frightened folk did weep and wail,
I calmly left and then did turn my tail.

A pope banished me for my sins, ’tis said;
My travels in the Talmud can be read.
And sometimes I throw fire from the sky.
Now, reading this, can you say what am I?
