nebulae

A large, dark cloud is contained within the frame. In its top half it is textured like smoke and has wispy gaps, whereas at the bottom and on the sides it fades gradually out of view. On the left are several orange stars: three each with six large spikes and one behind the cloud, which colors it pale blue and orange. Many tiny stars are visible, and the background is black.

Complex Organic Ices Discovered in a Star-Forming Cloud

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 24 February 20231 March 2023

The presence of complex organic molecules such as methanol, ethanol, and acetaldehyde in a molecular cloud suggests that these and simpler ices might be available to planetary systems right from the start.

A gif showing the five first images from JWST, split into six images that flash for 2 seconds each. In order they are: the first deep field, the spectrum of WASP-96B, Stephan’s Quintet, the Southern Ring Nebula in near-infrared light, the Southern Ring Nebula in midinfrared light, and the Carina Nebula. Further descriptions of each image can be found within the article.

Earth's Water Came from Space Dust During Planetary Formation

Cody Sullivan by C. Sullivan 23 November 201510 January 2023

A new analysis of lava from the deep mantle indicates that water-soaked dust particles, rather than a barrage of icy comets, asteroids, or other bodies, delivered water to the newly forming Earth.
