The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. Some scientists suggested that Hubble observations are wrong due to some creeping inaccuracy in its deep-space yardstick. However, Webb’s sharp infrared views of milepost markers known as Cepheids agree with Hubble data.

UAH researchers closing in on helping to solve 60-year-old solar mystery
Researchers at The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, have supported a ground-breaking measurement that is helping solve a 60-year-old cosmic mystery that involves the question of why the Sun’s corona, the outermost part of the Sun’s atmosphere, is so much hotter than the surface of the Sun itself.
ESA Solar Orbiter confirms solar switchback origin theory by UAH’s Dr. Gary Zank
For the first time a solar switchback has been directly observed that confirms 2020 models by astrophysicist Dr. Gary Zank at The University of Alabama in Huntsville (UAH) that theorized how these surprising structures in the solar wind originate.
When the James Webb telescope launches, 25 years of UAH R&D involvement will soar
After a scheduled November launch, when NASA’s James Webb Space Telescope (JWST) achieves orbit and unfurls the 18 gold-coated beryllium segments of its 6.5-meter primary mirror, over two decades of crucial UAH partnership in the project will also blossom.
Evidence of Broadside Collision With Dwarf Galaxy Discovered in Milky Way
Astrophysicists announced today that a 3-billion year old merger between a dwarf galaxy and the Milky Way produced a series of telltale shell-like formations of stars in the vicinity of the Virgo constellation, the first such “shell structures” to be found in the Milky Way.
Sentinel-6 sea level tracking satellite gives boost to climate science
A new satellite developed by engineers at the European Space Agency and the National Aeronautics and Space Administration will soon be orbiting the Earth, measuring sea level rise. The Sentinel-6 Michael Freilich satellite will lift off Nov. 10 in a…
