Galaxies are thought to form and grow by collisions and mergers, and elliptical galaxies may be the ultimate result of this ...

The James Webb Space Telescope’s Near-Infrared Camera captured an "array of stars that make up the dwarf galaxy Wolf–Lundmark–Melotte (WLM)," according to the NASA. Zoom into the imagery ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

Known for its large mass despite emitting very little light, Segue 1 is traditionally viewed as a prime candidate for studying dark matter-dominated galaxies. However, the unique investigation ...

Researchers propose that early elliptical galaxies may be responsible for a significant portion of the cosmic microwave background, potentially undermining the Big Bang’s most trusted evidence.

The background elliptical galaxy NGC 4860 can be seen in the upper left. The stellar distributions coincident with the western H 𝛼 blobs, B1 and B2, are indicated. Credit: arXiv (2025).

The interactive online map, created using data from NASA's James Webb Space Telescope, details some 800,000 galaxies across a vast cosmic distance. Scrolling and zooming in can take users some 13. ...

ASKAP J0107–2347, located around 1.5 billion light-years away, is also remarkable because it features two sets of radio lobes ...
