We can learn a lot about climate change from Venus, our sister planet. Venus currently has a surface temperature of 450℃ (the temperature of an oven’s self-cleaning cycle) and an atmosphere dominated by carbon dioxide (96%) with a density 90 times that of Earth’s. Venus is a very strange place, totally uninhabitable, except perhaps in the clouds some 60 kilometers up where the recent discovery of phosphine may suggest floating microbial life. But the surface is totally inhospitable. However, Venus once likely had an Earth-like climate. According to recent climate modelling, for much of its history Venus had surface temperatures…

When the Hubble Space Telescope set its sights toward the binary star system HD 106906, astronomers found a world that could resemble the long-sought Planet X. For the first time, astronomers are able to view a massive Jupiter-like world orbiting far from its parent star. The planet is visible orbiting at a distance beyond the debris field surrounding the stellar furnace. Such a world would resemble the hypothesized Planet X, thought by some astronomers to orbit beyond Neptune in our own solar system. The planetary disk in the HD 106906 system is similar, in some ways, to the Kuiper Belt in…
