Elon Musk is not a fan of NASA Acting Administrator Sean Duffy. The SpaceX founder and CEO has hammered Duffy repeatedly on social media over the past few days, calling
Some think it’s a no brainer: Scattering microscopic particles of sulfur into Earth’s atmosphere would reduce the amount of sunlight that reaches the ground, thereby cooling the planet. Indeed, this
Schematic representation of the relationship between criteria, “arguments,” and false positive/negative potential within the Life Detection Knowledge Base (LDKB). Knowledge sourced from peer-reviewed publications is represented in the LDKB in
Every superhero — or antihero — needs a sidekick. And it turns out that Beetlejuice Betelgeuse does indeed have one! The red supergiant star found in the constellation Orion has
The time evolution of the stellar spectra occulted by the planet as a function of orbital phase, in the wavelength range 5882–5902 Å, which includes the sodium doublet. The positions
