Living on Mars would probably suck — here's why Kelly and Zach Weinersmith join us to discuss their book A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through ..read more

Extracting high-order cosmological information in galaxy surveys with power spectra Baryon Acoustic Oscillations (BAO) are formed in the early universe and can be measured galaxy redshift survey to probe dark energy, but this feature is degraded with galaxy structure evolution. The authors propose a method that simultaneously use pre- and post-reconstruction power spectra to extract higher order information for surveys to constrain cosmological models ..read more

Long-baseline quantum sensor network as dark matter haloscope Nearly a century after dark matter was proposed, yet its nature remains elusive. Here, authors present their dark photon dark matter search results using two atomic magnetometer arrays 1700 km apart in large magnetic shields and offer the strongest terrestrial constraint in this mass range to date ..read more

Free-floating binary planets from ejections during close stellar encounters Simulated close encounters between planetary systems and other stars reveal that outer giant planets on wide orbits tend to be ejected, with a fraction of them forming bound pairs. This scenario would lead to a population of free-floating binary planets in dense stellar environments ..read more

High-resolution observations and numerical simulations provide insight into solar atmospheric heating What mechanisms power the heating of the solar atmosphere is a long-standing, complex question. Satellite and sounding-rocket observations, coupled with computer simulations, now support the idea that dissipation of electrical currents causes strong heating in the brightest parts of the solar chromosphere and corona ..read more
