The "habitable zone" of a planet usually concerns its distance from the star such that it can support liquid water. But what if the star fries the surface with intense stellar winds?
The headlines for some scientific news stories might leave philosophers of science wagging their heads. Few, though, are the reporters willing to call something really dumb, or at least questionable—especially if it appears to support evolution.
Hydrogen cyanide is one of the most reactive and toxic molecules we know, but astrobiologists view it with almost alchemical qualities for the origin of life.
The press and TV treat presumed scenarios like a "snowball Earth" as historic facts. A look at how the sausage is made, however, shows little empirical meat and mostly filler in a process characterized by tweaking, picking, and constant debate.
Origin-of-life researchers assume that intelligently-designed experiments in the lab can inform them about the emergence of life without design – in short, that design proves non-design.
Like Enceladus, Saturn's moon Titan shows multiple signs of being far less than 4.5 billion years old – yet the press releases are strangely silent about the implications.
Planetary scientists have figured out that the geysers of Enceladus vary during its orbit, but seem oddly silent about the question of how long the little moon could remain so active.
Another epic photo of Earth from space was taken on July 19 of Earth from Saturn by Cassini, and released on July 22. From Mercury, the MESSENGER spacecraft also portrayed Earth as a small dot.
