Astronomers have identified a bright hydrogen emission from a galaxy in the very early universe. The surprise finding is ...

CU Boulder researchers found massive, dust-filled galaxies called UFOs using JWST, challenging previous galaxy formation ...

Most galaxies are spiral, spherical or ellipsoidal aggregations of stars, but some have irregular configurations. These unusual objects may very well be galaxies in an early stage of evolution ...

Here’s how it works. Astronomers have discovered something surprising about the universe's smallest and faintest class of galaxies: Ultra-Diffuse Galaxies (UDGs). A research team studying these ...

Galaxies with irregular or unusual shapes are known as peculiar galaxies, and typically result from disruption by the gravitational pull of neighboring galaxies. Such interactions between nearby ...

Using Spektr-RG and Chandra space observatories, Chinese astronomers have investigated a nearby spiral galaxy known as NGC ...

Astronomers have discovered a group of dwarf galaxies that are unusually aligned in a near-straight line, with most of them rotating in the same direction. These peculiar features challenge ...

Caltech researchers have mathematical evidence suggesting a Neptune-sized Planet X may exist deep in the solar system in an orbit far beyond Pluto. Planet X could have a mass about 10 times that of ...

NASA's Hubble Space Telescope has captured stunning images of black holes, revealing their energy and interactions with surroundings. These images sho ...

astronomers using the Hubble Space Telescope believed that galaxies had mostly irregular and peculiar structures that resemble mergers. However, the superior abilities of JWST now allows us to see the ...

A Catalogue of Southem Peculiar Galaxies and Associatlons (2-volume set). Halton C. Arp and Barry F. Madore. Cambridge University Press: May, $125. Volume 1 presents information on more than 6,000 ...

Astronomers believe it involved a runaway process called "inflation," in which a peculiar type of energy ... years after the big bang many smaller galaxies merged into larger ones, forming an ...
