Many people have been unable to travel due to the pandemic, or even take a ‘staycation’. This August, we encourage you to slow down, look after your mental health, and let these stunning photographs transport you to a different place.
After five years of construction, the Large High Altitude Air Shower Observatory is nearing completion, but already returning exciting results on the origin of cosmic rays, explains Principal Investigator Zhen Cao.
The missing baryon problem may now be resolved, but the exact location and physical properties of the diffuse component remains unclear. This problem could be tractable, but requires a combination of new galaxy redshift surveys and new X-ray and radio facilities.
Identifying the sources of high-energy cosmic neutrinos has been a challenge. Considering frequentist and Bayesian arguments, as well as the special conditions found in neutrino astronomy, we discuss whether to believe current 3σ observations.
After years of relative neglect, Venus is enjoying renewed interest, with several missions bound to reach it in the next decade. Many questions about its nature still need to be answered, including regarding the highly debated presence of phosphine.
The Keck Planet Imager and Characterizer develops the Keck II telescope’s adaptive optics and instrument systems to enable infrared imaging and spectroscopy of gas giant exoplanets, explains Principal Investigator Dimitri Mawet.
That the interstellar object 1I/2017 U1 (‘Oumuamua) could be an extraterrestrial artefact is an unorthodox hypothesis. From a philosophical perspective, however, the structure of the underlying argument for the hypothesis is flawed.
