A new study shows black holes can form without singularities, using only modifications to Einstein’s equations.
NASA’s James Webb Space Telescope unlocks the mystery of Phoenix galaxy cluster’s star formation
NASA's James Webb Space Telescope (JWST) has recently made observations about galaxy clusters that will help shape our ...
It’s neither fast nor food, but a spectacular object called HH 30 looks appetizing for astronomers in a new image from the ...
In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...
White dwarfs, once thought lifeless, could host habitable planets. The James Webb Telescope is searching for atmospheric ...
NASA's SPHEREx telescope, launching Feb. 27, will scan the galaxy for frozen water and ices, mapping molecular clouds to ...
The elliptical galaxy NGC 4660 is one of a hundred galaxies imaged by Hubble that are members of the nearest large galaxy cluster to Earth, the Virgo Cluster. NASA’s James Webb Space Telescope has ...
New findings explain the Phoenix cluster's mysterious starburst. Data confirm the cluster is actively cooling and able to generate a huge amount of stellar fuel on its own.
Most massive galaxies have black holes at their cores that emit energetic particles, heating the galaxy’s gas and dust.
The core of the Phoenix cluster is shown across the whole electromagnetic spectrum. The bright purples represent X-rays produced by the hot gas, and the dashed purple outlines show regions where this ...
Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could ...
