Image: Hubble spots an interstellar interaction
The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion).

Astronomers dissect the anatomy of planetary nebulae using Hubble Space Telescope images
Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the American Astronomical Society on Friday, Jan….

BISTRO explores complex magnetic field structure of Cat’s Paw Nebula
An international team of astronomers has investigated a nearby emission nebula and star-forming region dubbed the Cat’s Paw Nebula as part of the B-field In STar-forming Region Observations (BISTRO) survey. Results of this study, presented in a paper published December 24 on arXiv.org, provide essential information about the structure of the object’s complex magnetic field.

What are ‘open’ star clusters?
Open clusters are young, loosely bound gatherings of stars that may still be surrounded by the nebula – or space cloud – in which they were born. The Pleiades, Hyades, and Beehive are well-known examples of open star clusters. Source: https://earthsky.org/astronomy-essentials/definition-examples-what-are-open-star-clusters…
