Nancy Grace Roman Space Telescope The Nancy Grace Roman Space Telescope (hereafter, Roman) is NASA’s next astrophysics flagship mission. When fully operational in 2027, Roman will provide the astronomical community

Exoplanet Discovery Database Discovering an exoplanet doesn’t mean having one, definitive eureka moment. Instead, it requires multiple observations, sometimes from multiple observatories, and the scientific community coming together in agreement

Schematic diagram showing the three stages of cooling from Bondi radius delaminations. In (a), the planet forms a Bondi radius boundary layer of thickness ∆RB with a temperature contrast ∆TB

Binary collision-induced H2–He absorption coefficient, α, normalized by the hydrogen and helium gas densities, as function of frequency in the fundamental band, at 296 K. The parato-ortho distribution, is representative
