Three decades of space telescope observations converge on a precise value for the Hubble constant

Three decades of space telescope observations converge on a precise value for the Hubble constant

This collection of 36 images from NASA’s Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have been used to refine our measurement of the Hubble constant, the expansion rate of the universe. …

Boeing crew capsule launches to space station on test redo

CAPE CANAVERAL, Fla. (AP) — Boeing’s crew capsule rocketed into orbit Thursday on a repeat test flight without astronauts, after years of being grounded by flaws that could have doomed the spacecraft. Only a test dummy was aboard. If the capsule reaches the International Space Station on Friday and everything else goes well, two or …

Galaxies without dark matter perplex astronomers

Galaxies without dark matter perplex astronomers

This Hubble image captures a set of galaxies that are unusual because they seem not to have dark matter.Credit: NASA/ESA/P. van Dokkum, Yale Univ. Astronomers think that galaxies cannot form without the gravitational pull of dark matter. So a trail of galaxies free of this mysterious material, with no obvious cause, would be a remarkable …
