Understanding how and why star formation turns off in massive galaxies is a major challenge for studies of galaxy evolution. Many theoretical explanations have been proposed, but a definitive consensus is yet to be reached.
The next-generation observatory Lynx will provide an unprecedented X-ray view of the otherwise invisible Universe, directly observing the dawn of supermassive black holes, revealing the drivers of galaxy formation, tracing stellar activity including effects on planet habitability, and transforming our knowledge of the endpoints of stellar evolution.
LUVOIR is a concept for a powerful, flexible space observatory to enable the first survey for exoplanets most similar to the Earth, search for signs of life in our Solar System and beyond, and revolutionize astrophysics in the twenty-first century.
The Habitable Exoplanet Observatory (HabEx) is a conceptual space-based 4-m telescope with the means to image and characterize potentially habitable planets orbiting Sun-like stars, and with ultraviolet to near-infrared imaging and spectroscopic capabilities suited to general observatory science.
The Origins Space Telescope, one of four large Mission Concept Studies sponsored by NASA for review in the 2020 US Astrophysics Decadal Survey, will open unprecedented discovery space in the infrared, unveiling our cosmic origins.
The 2020 US Decadal Survey for Astrophysics is almost here — but in these years of flat cash and major mission delays, how much can we afford to dream?
The Development in Africa with Radio Astronomy (DARA) project, a joint venture between the UK, South Africa and African partner nations, aims to provide development, education, training and careers advice to Africans through radio astronomy and related technical disciplines.
The HESS array in Namibia waits for a split-second flash of blue light — Cherenkov radiation — that signals an atmospheric shower of charged particles caused by cosmic rays, explains Director Mathieu de Naurois.
