Feb. 27, 2025 — Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What ...

The largest ... of galaxies in groups over the past 12 billion years of cosmic time." The James Webb Space Telescope began operating in 2022. The largest telescope in space, its higher resolution ...

Previous research assumed that once dwarf galaxies formed, they would scatter into random orbits. But the new simulations followed the evolution of the gas to much greater resolution and precision ...

Elliptical galaxies would be better called spheroidal; they can be spherical but are more commonly elongated, a bit like a cotton ball. Some of the largest galaxies we know are elliptical ...

Experimental results show that the sensor achieved an angular resolution of 0.003° and an online detection accuracy of 0.029° for angular position. The abrupt change in the voltage amplitude caused by ...

Jackie explains that a laser inside the tubes is split, bounces off mirrors, and goes straight back to sensors at the center ...

Observation data from an international research team composed of researchers from 45 institutions around the world has found that the supermassive black hole jet at the center of one of the largest ...

Abstract: We present matched-resolution VLA H i and SCUBA 850-μm maps of 20 IRAS-bright galaxies. Of the galaxies observed, two were not detected in H i and two were detected in absorption. The H i ...

itself part of the massive Laniakea Supercluster of galaxies. The largest galaxy discovered to date is IC 1101. Under the galactic morphological classification system, it’s listed as a “supergiant c-D ...

Lu Lu looks forward to the next two decades of neutrino astrophysics, exploring the remarkable detector concepts needed to ...

A view of the spiral galaxy NGC 3982, as seen by NASA’s Hubble Space Telescope. Galaxies come in many different variations, but astronomers classify them into four main types: spiral ...
