Wormwood in the Bible 
Although the word wormwood appears several times in the Old Testament, translated from the Hebrew term לענה (la'anah), its only clear reference as a named entity occurs in the New Testament, in the book of Revelation: "The third angel blew his trumpet, and a great star fell from heaven, blazing like a torch, and it fell on a third of the rivers and on the springs of water. The name of the star is Wormwood. A third of the waters became wormwood, and many died from the water, because it was made bitter." (Revelation 8:10–11, New Revised Standard Version).
Interpretations of Revelation 8:10 
Certain commentators have held that this "great star" represents one of several important figures in political or ecclesiastical history, while other Bible dictionaries and commentaries view the term as a reference to a celestial being. A Dictionary of The Holy Bible states, "the star called Wormwood seems to denote a mighty prince, or power of the air, the instrument, in its fall."
Historist interpretations 
Various religious groups and figures, including Seventh-day Adventists and the theologians Matthew Henry and John Gill, regard the verses of Revelation 8 as symbolic references to past events in human history. In the case of Wormwood, some historist interpreters believe that this figure represents the army of the Huns as led by king Attila, pointing to chronological consistencies between the timeline of prophecy they have accepted and the history of the Huns' campaign in Europe. Others point to Arius, the emperor Constantine, Origen or the ascetic monk Pelagius, who denied the doctrine of Original sin.
Futurist interpretations 
Various scientific scenarios have been theorized on the effects of an asteroid or comet's collision with Earth. An applicable scenario theorizes a chemical change in the atmosphere due to "heat shock" during entry and/or impact of a large asteroid or comet, reacting oxygen and nitrogen in the atmosphere to produce nitric-acid rain. Acid rain from the heat shock of a large comet or asteroid's impact with Earth is believed by some to fit the Biblical description of the bitterness produced by the Wormwood Star upon a third of the Earth's potable water.
Gerardus D. Bouw, Ph. D. in his white paper "Wormwood" theorizes that since the term wormwood refers to a bitter or poisonous plant, specifically "apsinthos, that is, absinthe wormwood" in Revelations 8:11 and that a star falling would likely be a asteroid or comet ... the most reasonable scenario being a comet, since they could have a chemical makeup that would make the waters bitter and poisonous and would have to break up by some means, "in order to fall on deep sources of water and rivers, the object cannot be in one piece when it arrives in the atmosphere."
Alternative interpretations 
A number of Bible scholars consider the term Wormwood to be a purely symbolic representation of the bitterness that will fill the earth during troubled times, noting that the plant for which Wormwood is named, Artemisia absinthium, or Mugwort, Artemisia vulgaris, is a known Biblical metaphor for things that are unpalatably bitter. One interesting theory is that nuclear weaponry could be called wormwood. For example: Ukrainian synonymy 'wormwood'. They do poison the water where they are detonated, thus explaining the correlation. Some even point to the Chernobyl disaster as a possible fulfillment of this prophecy, as the name Chernobyl is said to translate to "wormwood."

- The city is named after the Ukrainian word for mugwort or wormwood (Artemisia vulgaris), which is чорнобиль "chornobyl". The word is a combination of the words chornyi (чорний, black) and byllia (билля, grass blades or stalks), hence it literally means black grass or black stalks. That may signify burnt grass, perhaps prior to cultivation.
