Early in her career, Nancy Grace Roman ignored those who advised her not to become a scientist because of her gender.Credit: NASA/Science Photo Library Astronomers have a new tool for peering into the Universe to probe dark matter, dark energy and exoplanets. The Nancy Grace Roman Space Telescope, launched on 30 August, is the first

The kine algorithm is a static or dynamic image reconstruction algorithm for interferometric data. It is a forward imaging method, based on a neural field representation43 of the brightness distribution of the source. In this section, we describe our methodology, starting with a general overview of VLBI measurements followed by an explanation of the kine
