Lengthened to the size of a tennis court, the five-layer sunshield of NASA's fully assembled James Webb Space Telescope successfully completed a final series of large-scale deployment and tensioning tests. This milestone puts the observatory one step closer to its launch in 2021. "This is one of Webb's biggest accomplishments in 2020," said Alphonso Stewart, Webb deployment systems lead fo

A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the universe is expanding. "We studied signals that came from various sources, for example recently observed mergers of neutron stars," said Ingo Tews, a theorist in Nuclear

An international team of researchers has identified over 109,000 previously unrecognized impact craters on the moon using machine learning methods. The study, led by researchers from Jilin University, was published in the journal Nature Communications. Impact craters are the most prominent lunar surface feature and occupy most of the moon's surface. With traditional automatic identif

It took fifteen years of imaging and nearly three years of stitching the pieces together to create the largest image ever made, the 8-trillion-pixel mosaic of Mars' surface. Now, the first study to utilize the image in its entirety provides unprecedented insight into the ancient river systems that once covered the expansive plains in the planet's southern hemisphere. These three billion-year-old
