Where is Jesus' body now? In Acts 1 we're told:

After he said this, he was taken up before their very eyes, and a cloud hid him from their sight. They were looking intently up into the sky as he was going, when suddenly two men dressed in white stood beside them. “Men of Galilee,” they said, “why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven.” Acts 1:9-11 (NIV)

It is not clear to me what the angels mean by Jesus being taken &quot;into heaven&quot;. Some Christians believe that Jesus must still have his physcal body, and therefore is present somewhere in our universe. Others interpret &quot;heaven&quot; to mean the spiritual realm, and therefore Jesus in some way transitioned out of our physical realm, although that leaves the question of what happened to his body.
How does Reformed Theology understand where Jesus went when he ascended, and what is their explanation for where Jesus' physical body is now?
St. Paul anticipated questions on the resurrected body of a person, on account of which he says at 1 Cor 15: 35-49:

But someone may ask, “How will the dead be raised? What kind of bodies will they have?”  What a foolish question! When you put a seed into the ground, it doesn’t grow into a plant unless it dies first.  And what you put in the ground is not the plant that will grow, but only a bare seed of wheat or whatever you are planting.  Then God gives it the new body he wants it to have. A different plant grows from each kind of seed.  Similarly there are different kinds of flesh—one kind for humans, another for animals, another for birds, and another for fish.
There are also bodies in the heavens and bodies on the earth. The glory of the heavenly bodies is different from the glory of the earthly bodies. The sun has one kind of glory, while the moon and stars each have another kind. And even the stars differ from each other in their glory.
It is the same way with the resurrection of the dead. Our earthly bodies are planted in the ground when we die, but they will be raised to live forever.  Our bodies are buried in brokenness, but they will be raised in glory. They are buried in weakness, but they will be raised in strength.  They are buried as natural human bodies, but they will be raised as spiritual bodies. For just as there are natural bodies, there are also spiritual bodies.

If the scripture says that Jesus was taken up into heaven, He is present in heaven in body. Of course, that body is something which transcends human comprehension, just as St. Paul was  trying to explain to the Corinthians.
