Earth isn’t the only planet to go through ice ages. A handful have hit our home planet in the last 2.5 billion years, with the most recent – which peaked
Photometric 2-minute cadence PDCSAP time series of TIC 4897275 (HD 85426) in TESS sectors 21 (top panel) and 48 (bottom panel) are shown in grey, with 30-minute binned data overlaid
Primary (circles, ≤ 2 mas) and reserve (triangles, 5 mas) candidate reference stars plotted in ecliptic coordinates in epoch J2027 and equinox 2027 with colors indicating rankings. The CVZs are
The 13.6 − 17.7 µm range of the GM Aur spectrum. The continuum-subtracted JWST-MIRI data (black, top panel) is overlaid with the total modeled emission (red, top panel) from molecules
A figure illustrating the sensitivity of a carbon rich stellar outflow with a MCMC sampler varying reaction rates of the entire network. — astro-ph.GA Since the first observations of interstellar
Climatology of diurnal pressure variation (dP/dt) in units of Pa h⁻¹. High-frequency signals (with periods shorter than 3,700 s) were removed from the original time series prior to differentiation. Sunrise
A vantage point on “Vera Rubin Ridge” provided NASA’s Curiosity Mars rover this detailed look back over the area where it began its mission inside Gale Crater, plus more-distant features
Global distribution of the four major nonwater species in Europa’s surface ice with reaction rate coefficients scaled down by a factor of 10. (a) H2SO4. (b) SO2. (c) H2O2. (d)
This artist’s impression shows a coronal mass ejection (CME) around another star. We see these eruptions coming often from the Sun. During a CME, massive amounts of material are flung
