An illustration illustrating the rotation of neutral hydrogen (right) in galaxies located in an elongated galaxy (middle), with the galaxies showing a coherent overall rotational motion that follows the large-scale cosmic fabric (left).

One of the largest rotating structures ever seen: a giant cosmic filament where galaxies spin “in the same direction”

Image: This artist's rendering of a planet-forming disk surrounding a young star shows a swirling "pancake" of hot gas and dust from which planets form. Using the James Webb Space Telescope, the team obtained detailed images showing the layered, conical structure of the disc's winds - streams of gas blowing out into space.

Astronomers have discovered new details about gas flows that shape planet-forming disks and shape them over time, offering a glimpse into how our solar system likely formed
The nearby star V889 Hercules rotates fastest at about 40 degrees latitude. This unusual rotation profile challenges established stellar models. Credit: Jani Närhi, University of Helsinki

Strange star amazes astronomers: V889 Hercules breaks the laws of rotation of stars

The sun rotates fastest at the equator and the rate of rotation slows down at higher latitudes, while in the polar regions it is the slowest. But a nearby Sun-like star, V889 Hercules in the Hercules group 115 light years away
For the first time, a phenomenon that astronomers had long hoped to photograph directly has been captured by the NASA/ESA/CSA James Webb Space Telescope's Near Infrared Camera (NIRCam). In this spectacular image of the Serpent Nebula, the discovery is in the northern region of the Young Zone And this star-forming relative NASA, ESA, CSA
