Gas-phase C/O ratio as a function of distance to the star for the two different values of the stellar mass (M∗ = 1, 0.1 M⊙) and three values of the

Evolution of the number of planets in one system averaged over 20 runs, ⟨Np⟩. The horizontal axes are the time normalized by the Kepler period of the innermost planet in

Illustration of the various probabilities discussed. The variable x may refer to any of the physical constants α, β, γ etc., with the others integrated over. The dashed lines indicate

Lander prototype during field tests at Matanuska Glacier, Alaska (Credit: NASA/JPL-Caltech) Europa, a moon of Jupiter, is a high-priority target for space exploration because of its potential to harbor life.

The architectures of the systems with both small planets and cold Jupiters considered in this work and ordered according to increasing semi-major axis of the innermost planet (from bottom to

Face-on view of the circumplanetary habitable zone of HD 114386 b assuming an Earth analog moon on e = 0.05 orbit around the planet. The axes represent the distance from

The early universe and its expansion. Credit: NASA’s Goddard Space Flight Center Conceptual Image Lab We demonstrate that dark matter interactions can profoundly influence stellar nucleosynthesis in the early universe

Deep-sea dive activity, 1958–2024. (A) Deep-sea dive activity has been concentrated in a small number of locations, particularly (B) Monterey Bay, USA; (C) Hawai’i, USA; (D) Suruga and Sagami Bays,
