How did this 20-light-year-wide 'Diamond Ring' form in space? Maybe a cosmic bubble burst

Astronauts aboard the International Space Station (ISS) captured stunning photographs of two comets as they danced above the northern lights. This remarkable event highlights the unique vantage point of the ISS, allowing astronauts to witness celestial phenomena from low Earth orbit.

Astronomers have utilized new computer simulations to address long-standing mysteries surrounding massive radio 'relics' that emerge during the collision of galaxy clusters. These simulations provide insights into the physics of these enigmatic structures, enhancing the understanding of cosmic phenomena.

Rocket Lab successfully launched a satellite for a 'confidential commercial customer' on November 20, shortly after announcing the launch. The details regarding the satellite's purpose and the identity of the customer remain undisclosed.

Blue Origin, founded by Jeff Bezos, has announced plans to develop a 'super heavy' version of its New Glenn rocket, which recently achieved a successful second launch. This new variant aims to enhance the rocket's capabilities and performance.

A new model has successfully mapped a record-breaking 100 billion stars in the Milky Way, significantly enhancing simulation detail. This advancement accelerates processing time and integrates smaller-scale events, such as supernova explosions, alongside larger galactic processes.

Uranus will reach its brightest point in the sky on November 21, appearing directly opposite the sun from Earth's perspective. This astronomical event allows observers to see the planet more clearly than at other times of the year.

The Rubin Observatory has made a significant discovery by identifying a stream of stars that is longer than the entire Milky Way. This finding emphasizes the vast unknowns regarding the life histories of galaxies and the influence of the hidden universe on observable realms.

Astronauts aboard the International Space Station (ISS) recently observed comet Lemmon appearing to be absorbed by an aurora, a rare sight from low Earth orbit. This event highlights the unique perspectives astronauts have on celestial phenomena.
