When we look at Earth from space, we see a blue, watery world. It is no coincidence that three quarters of the surface is covered by oceans. Water is very common in the universe and is essential for lives. But life needs water in the form of liquid, not ice, and not vapor and ...

"They will offer the entire science community the chance to investigate a planet we haven't been to in more than 30 years." He added: "We hope these missions will further our understanding of how Earth evolved and why it's currently habitable when oth...
Is Ceres habitable? Where was the Kuiper belt discovered? How was the planet Pluto discovered? Where was the planet Mercury discovered? Was Neptune the first planet to be discovered? When was Ursa Major discovered? When was Pluto demoted to a minor planet? How was Halley's Comet discovered?

Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth's climate warm and habitable. Without this process, Earth could not sustain life. However, the "man-made greenhouse effect" has now become a big problem. When people produce huge ...
But Blue Origin has not publicly announced the specific launch date and time, only that is nearing the first launch of New Glenn after a succesful first stage hot-fire test on Dec. 27 at its pad, Space Launch Complex 36, in Cape Canaveral. The mission will be ambitious, test...
"We're very hopeful that the national community in 2020 will fund one of these things and go forward," said Karl Stapelfeldt, the chief scientist of NASA's exoplanet science program. The aim is not only to be able to look at Earth-like planets around nearby stars, he said, but to st...
Not bad for a bunch of evolved primates, but it raises an interesting question. Could we even reach Type I? After all, we can't capture all the sunlight that reaches Earth and still have a habitable planet. This question is studied in a paper recently posted to Arxiv. The paper looks...
