Best-fit model to an empirical transmission spectrum of the cloudless Earth in units of scale height, H (adapted from (40)). Different colors indicate the contributions from various molecules. Despite its
Major steps in the disk detection process on two cubes: (far left) an unaltered cube; (center left) edge pixels identified using Canny edge detection – some pixels along terrain boundaries
Schematic of the layered systems: CO2 deposited on (a) bare gold (Au), (b) water ice on gold, (c) a silicate film on gold, and (d) ice on a silicate film
Envelope H2O mass fraction as a function of semi-major axis. The same dataset as in Figure 1 is shown. The left panel shows planets that predominantly formed inside the water
The 134Xe/132Xe versus 136Xe/132Xe diagram showing the composition of Tatahouine (#13349) and Shalka (#6766 C) measured at different heating steps, including those of Michel & Eugster (1994) and Eugster &
During this upcoming week, skywatchers across most of the U.S. and southern Canada will get an opportunity to view the two largest space vehicles now in orbit around the Earth
Not one, but two exploding stars are currently visible to the naked eye in the southern night sky, a cosmic coincidence that’s “exceedingly rare” and may soon vanish from view
Astronomers have teamed up with citizen scientists to discover a brand-new exploding star that’s greedily feeding on a stellar companion. The newly observed binary system features a cataclysmic variable star,
