A new possible explanation for the Hubble tension
The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values......»»
Astronomers explore the properties of ultra-diffuse galaxy UGC 9050-Dw1
Using the Hubble Space Telescope (HST) and Jansky Very Large Array (VLA), astronomers have investigated an ultra-diffuse galaxy known as UGC 9050-Dw1. Results of the study, published June 9 on the pre-print server arXiv, yield important insights into.....»»
Even though they"re bigger, Generation 2 Starlinks are fainter than Gen1
We've filed plenty of reports here at UT warning about the potential impact of Starlink and similar satellites on the field of astronomy. We've gone so far as to point out that the granddaddy of space-based telescopes—Hubble—has already had some.....»»
