Venus will reach its highest altitude in the morning sky on Aug. 1 while shining close to Jupiter in the ‘hand’ of the constellation Orion. Stargazers in the U.S. will
Technicians have successfully installed two sunshields onto NASA’s Nancy Grace Roman Space Telescope’s inner segment. Along with the observatory’s Solar Array Sun Shield and Deployable Aperture Cover, the panels (together
A visualization of the spectral coverage and (cumulative) on-target integration times. See Table 2 for more information on the spectral settings. The background grayscale shows a representative composite spectrum of
Eccentricity of inner super-Earth vs. the semimajor axis ratio between the outer cold Jupiter and the inner super-Earth from observations, with the color of the symbol showing the semimajor axis
Time series of atmospheric temperature and He column density for the observation day January 26, 2023. Blue and gray points represent the 20x binned and unbinned best-fit planetary parameters obtained
Stars are born in clouds of dust and gas, and around them, planets slowly begin to take shape. Astronomers have long theorized how planets form from these swirling discs, but
Captain Kirk always had a reputation as a ladies’ man. Throughout the Enterprise’s famous five-year mission, he frequently set phasers to love, punctuating the important business of boldly going with
