Southern Ring Nebula (NIRCam and MIRI images side by side). NASA’s James Webb Space Telescope offers dramatically different views of the Southern Ring Nebula. Each image combines near- and mid-infrared light from three filters. At left, Webb’s image of the Southern Ring Nebula highlights the very hot gas that surrounds the two central stars. At …

Galactic cannibal Andromeda feasts on smaller galaxies, cosmic leftovers reveal

Leave a Comment / Science / By

Andromeda, the Milky Way’s neighboring spiral galaxy, may be a cosmic cannibal that has been growing by chowing down on smaller galaxies. Astronomers reached this conclusion by observing a globular cluster of stars called the Dulais Structure, named after the Welsh term for “black stream,” which now dwells in Andromeda but seems to have originated …

A particle accelerator that just turned on could reveal rare forms of matter

Leave a Comment / Science / By

Just a few hundred feet from where we are sitting is a large metal chamber devoid of air and draped with the wires needed to control the instruments inside. A beam of particles passes through the interior of the chamber silently at around half the speed of light until it smashes into a solid piece …

Four distant galaxies in SMACS 0723. Analysis of the very first image from the James Webb Space Telescope shows that the infrared telescope reveals details of galaxies from the time when the universe was only about 1 billion years old. Left: the first image with four galaxies highlighted. On the right, the four galaxies each …

Cross-section through a tentacle of a transgenic sea anemone showing differentiation products of the SoxC cell population (magenta) and retractor muscles (yellow). Credit: Andreas Denner In sea anemones, highly conserved genes guarantee the lifelong differentiation of neurons and glandular cells. Sea anemones are seemingly immortal animals. They seem to be immune to aging and the …

Ghost Particles Crashing Into Antarctica Reveal Unseen Heart of Nearby Galaxy

Leave a Comment / Science / By

About 47 million light-years from where you’re sitting, the center of a black-hole-laden galaxy named NGC 1068 is spitting out streams of enigmatic particles. These “neutrinos,” otherwise known as the notoriously elusive “ghost particles,” haunt our universe but leave little trace of their existence. Immediately after coming into being, bundles of these invisible bits plunge …
