Thanks to data from a magnified, multiply imaged supernova, a team led by University of Minnesota Twin Cities researchers has successfully used a first-of-its-kind technique to measure the expansion rate of the Universe. Their data provide insight into a longstanding debate in the field and could help scientists more accurately determine the Universe's age and better understand the cosmos. ESO telescope reveals hidden views of vast stellar nurseries
Friday, 12 May 2023 02:56 Write a comment
Using ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in thick clouds of dust. Thanks to these observations, astronomers have a unique tool with which to decipher the complex puzzle of s Space Force commercial office to open new facility in Virginia

What if Titan Dragonfly had a fusion engine?
Thursday, 11 May 2023 17:32 Write a comment
In a little over four years, NASA's Dragonfly mission will launch into space and begin its long journey towards Titan, Saturn's largest moon. As part of the New Frontiers program, this quadcopter will explore Titan's atmosphere, surface, and methane lakes for possible indications of life (aka. biosignatures).
This will commence in 2034, with a science phase lasting for three years and three and a half months. The robotic explorer will rely on a nuclear battery—a Multi-Mission Radioisotope Thermal Generator (MMRTG)—to ensure its longevity.
But what if Dragonfly were equipped with a next-generation fusion power system? In a recent mission study paper, a team of researchers from Princeton Satellite Systems demonstrated how a direct fusion drive (DFD) could greatly enhance a mission to Titan. This New Jersey-based aerospace company is developing fusion systems that rely on the Princeton Field-Reversed Configuration (PFRC).
This research could lead to compact fusion reactors that could lead to rapid transits, longer-duration missions, and miniature nuclear reactors here on Earth.
