Then another sign appeared in heaven: and behold, a great red dragon having seven heads and ten horns, and on his heads were seven diadems.
Revelation 12:1 And a great sign appeared in heaven: a woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars.

Revelation 12:3 Then another sign appeared in heaven: and behold, a great red dragon having seven heads and ten horns, and on his heads were seven diadems.
Revelation 12:4 And his tail swept away a third of the stars of heaven and threw them to the earth. And the dragon stood before the woman who was about to give birth, so that when she gave birth he might devour her child.
Revelation 12:5 And she gave birth to a son, a male child, who is to rule all the nations with a rod of iron; and her child was caught up to God and to His throne.
The verse centers on "another", "sign", "appeared", "heaven", "behold", "great", "dragon", and "having". It is saying that the verse draws attention to "another" and "sign", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "And she was with child and she..." into verse 4's "And his tail swept away a third...", so "another" and "sign" belong inside that flow. In Revelation context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "another" and "sign" with trust shaped by these words, not by a vague optimism outside the passage.
