I've researched about this topic online and I could only find one Christian website so far that affirms this belief.
https://www.bible.ca/d-Jesus-body-now.htm
Does anybody else know if a particular Christian denomination believes this way too? Personally, it makes sense, logically, that Jesus doesn't have a physical body because human bodies freeze in space without a suit. Colossians 1:15 also explicitly states that the Son is the image of the invisible God.
Jehovah’s Witnesses believe that the body of Jesus was disposed of by Jehovah God, dissolved into its constituent elements or atoms, and what came out of the tomb was a spirit creature.
JESUS’ FLESHLEY BODY DISSOLVED: What happened to the perfect fleshly body of Jesus after his death? Was it preserved so that in time men will look upon it in worship? or does Jesus still have this fleshly body in the heavens, “spiritualized” so that it can be seen and worshiped? Neither. The Scriptures answer: It was disposed of by Jehovah God, dissolved into its constituent elements or atoms... Moses’ body returned to the dust by process of decay, as all human bodies do, but not so in Jesus’ case, for it is written: “For thou wilt not leave my soul to Sheol; neither wilt thou suffer thy holy one to see corruption.” (Ps. 16:10, AS; Acts 2:31) So God caused Jesus’ body to disappear, but not corrupt, meaning that it was dissolved, disintegrated back into the elements from which all human bodies are made.—John 20:1-13.
JESUS RESURRECTED WITH SPIRIT ORGANISM: The resurrected Jesus was given a spirit body: “He being put to death in the flesh, but being made alive in the spirit.” (1 Pet. 3:18, NW)
The article goes on say that the bodies that Jesus appeared in after his resurrection were materialized bodies. The article concludes that those who refuse to recognize the signs of Jesus’ invisible presence because of looking for his coming in a body of flesh are mistaken.

Hence Jehovah God the Father, who has life-giving power in himself, raised his Son from the dead on the third day to immortal life in heaven, in the spirit realm. ... When Jesus ascended to heaven forty days after his resurrection from the dead, he did not take the sacrificed human body to heaven with him—an impossibility!—but took with him the value of his sacrificed perfect human life, in order to present this to the heavenly Father in behalf of mankind.

Here is a quotation from a more recent Watchtower article:
The apostles knew that Jesus’ resurrection was different from the resurrections that preceded it. People who were brought back to life earlier came back with physical bodies and eventually died again. Jesus was resurrected with a spirit body that was imperishable. (Read Acts 13:34.) Peter wrote that Jesus “was put to death in the flesh but made alive in the spirit.” Moreover, “he is at God’s right hand, for he went to heaven, and angels and authorities and powers were made subject to him.” (1 Pet. 3:18-22) The previous resurrections were both marvelous and miraculous, but none compared to this supreme miracle.

With regard to the return of Christ Jesus, Jehovah’s Witnesses believe he will be invisible:
In what form does Christ return? He was resurrected as an invisible spirit person. (1 Peter 3:18) Then, he went to heaven and sat at God’s right hand. (Psalm 110:1) Much later, Jesus was brought before Jehovah God, “the Ancient of Days,” who granted Jesus power to rule over mankind. So Jesus returns, not as a human, but as an invisible King.

Jehovah’s Witnesses believe that after Jesus resurrection he materialised before his disciples to look like a human (even eating and drinking with them), but when he ascended into heaven, he was a spirit. Therefore they say Jesus does not have a physical body right now. Furthermore, when Jesus returns, they say it will not be in bodily form, but he will be an invisible spirit.
Please be aware that I am merely presenting the official view of Jehovah’s Witnesses.
