NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists
When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the "Hubble Tension," is that the current rate of the expansion of the ...
Astronomers Measure Heaviest Black Hole Pair Ever Found
Using archival data from the Gemini North telescope, a team of astronomers have measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has ...
Unveiling the Mysteries of the Solar Chromosphere with the Daniel K. Inouye Solar Telescope
The second layer of our Sun’s atmosphere, the chromosphere, is sandwiched between the Sun’s visible surface (or photosphere) below, and its outer atmosphere (or corona) above. In this layer, plasma properties such as temperature, pressure, ...
Webb Finds Evidence for Neutron Star at Heart of Young Supernova Remnant
NASA’s James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, ...
NASA’s Hubble Traces ‘String of Pearls’ Star Clusters in Galaxy Collisions
Contrary to what you might think, galaxy collisions do not destroy stars. In fact, the rough-and-tumble dynamics trigger new generations of stars, and presumably accompanying planets. Now NASA's Hubble Space Telescope has homed in on ...
NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies
It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active ...
