Espectrógrafo de alta precisión ayuda a confirmar descubrimiento planetario

NEID es un espectrógrafo de velocidad radial de alta precisión que está diseñado para medir el bamboleo extremadamente diminuto de las estrellas cercanas, utilizando el efecto de la velocidad radial. Este efecto resulta de la fuerza gravitacional mutua entre un planeta y su estrella…

High-Precision NEID Spectrograph Helps Confirm First Gaia Astrometric Planet Discovery

NEID (rhymes with fluid) is a high-precision radial-velocity spectrograph that is designed to measure the extremely minute wobble of nearby stars using the radial velocity effect. This effect results from the mutual gravitational force between a planet and its host star which causes the…

UAH researcher demonstrates Milky Way’s last major galactic collision happened much more recently than previously thought

Dr. Tom Donlon, a postdoctoral researcher at The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, is the lead author of a new paper published in the Monthly Notices of the Royal Astronomical Society that reveals the Milky Way Galaxy’s last major collision occurred billions of years later than previously thought.

NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists

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.
