Eta Space, a new space company dedicated to developing advanced cryogenic systems for the modern space and energy age, is celebrating its three-year anniversary in June with milestones scheduled for several key projects. Eta Space is developing LOXSAT, a 135 kg demonstration satellite designed to test critical cryogenic fluid management (CFM) technologies...

Vacuum technologies have advanced the field of cryogenics, allowing researchers to push the frontiers of what we know and businesses to apply that knowledge and drive innovation across a wide range of industries. The intersection of vacuum and cryogenic sciences is a demanding one. Pressure and temperature requirements create a...

Recently, NIRISS, one of NASA’s James Webb Space Telescope’s four primary scientific instruments concluded its postlaunch preparations and was declared ready for science. Now a second of Webb’s four primary scientific instruments, known as the Mid-Infrared Instrument (MIRI), has also concluded its postlaunch preparations and is now ready for science. MIRI’s coronagraphic imaging...

Theoretical physics is full of weird and wonderful concepts: wormholes, quantum foam and multiverses, just to name a few. The problem is that while such things easily emerge from theorists’ equations, they are practically impossible to create and test in a laboratory setting. But for one such “untestable” theory, an...

NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far. Webb’s First Deep Field is galaxy cluster SMACS 0723, and it is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared.  Webb’s image is approximately...

Researchers at the Max-Planck Institute for Nuclear Physics in Germany and the Columbia Astrophysics Laboratory have recently carried out an experiment aimed at measuring the rate of quantum transitions caused by collisions between molecules and electrons. Their findings, published in Physical Review Letters, offer the first experimental evidence of this rate, which had...
