Whether you’re a casual fan or a spaceflight enthusiast, see how well you know one of the companies pushing the boundaries of commercial space travel.

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, strengthening the mysterious Hubble tension. This mismatch could point to new physics rather…

The COVID-19 pandemic prompted a nationwide conversation in the U.S. about how much people trust scientists and trained medical professionals. But for some communities, distrust has been the norm.

Researchers have developed a method to detect the destruction of buildings using freely available satellite radar imagery. Daniel Racek and colleagues’ algorithm analyzes publicly available Sentinel-1 synthetic aperture radar images from the European Space Agency to identify destroyed buildings in…

A sudden X-ray flare from a supermassive black hole in galaxy NGC 3783 triggered ultra-fast winds racing outward at a fifth the speed of light—an event never witnessed before. Using XMM-Newton and XRISM, astronomers caught the blast unfold in real…

The image shows a good example of the phenomenon called airglow.

University of Phoenix College of Doctoral Studies announces a new white paper, “Leadership Opportunities for Increasing Employee Value through Artificial Intelligence,” authored by Andrew C. Lawlor, Ph.D., and Pamayla E. Darbyshire, DHA, MSN/CNS, both Fellows at the Center for Educational…

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star formation, shifts in flowing gas, and even streams of metal-poor material…

In other words, the matter traveled at 20% the speed of light.

Aetherflux has focused its efforts on space-based solar power, with the goal of “building an American power grid in space.”
