When we talk about the greenhouse effect (as opposed to global warming), we rarely mention the fact that most of it is not caused by carbon dioxide. But as a greenhouse gas, water vapor contributes 70% of the insulation that keeps solar energy in our atmosphere at the right temperature for life. Although it is… Read More »
NASA/ESA Allegation: The largest reservoir of water in space is equivalent to 140 trillion times the water in Earth’s oceans. Evaluation: Rating: True They are known to be extremely active and luminous beings in space. quasars. With almost a million quasars One in particular, identified by astronomers as of August 2023, is said to host… Read More »

Astronomers using the Hubble Space Telescope have discovered that the atmosphere of a relatively small planet outside the solar system is rich in water vapor. But don’t plan a holiday to this destination just yet. The planet’s surface is hot enough to melt lead, meaning it is a steamy world unsuitable for life as we… Read More »
Using advanced computer simulations, scientists have shown how easily a runaway greenhouse effect can turn a habitable planet into a hellish world uninhabitable. “Not only does this research have implications for our understanding of extrasolar planets,”outer planets,” but also provides insight into the human-caused climate crisis on Earth. The team, consisting of astronomers from the… Read More »
