Contour plots to approximate vshift for different offsets in ephemeris. The top three panels of the figure use fixed Kp values of 100 km s−1 , 150 km s−1 ,
Chile’s Atacama Desert is the driest non-polar desert on Earth — and a ready analog for Mars’ rugged, arid terrain. Credit: NASA/JPL-Caltech Larger image The Atacama Desert, one of the
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
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

A new study published in July 2025 tackles one of science’s most profound mysteries—how did life first emerge from nonliving matter on early Earth? Using cutting edge mathematical approaches, researcher
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
