Гантелька симетричний джет вмерлої зорі? Такі вуха є на осі Стожар і ще у космосі, принаймні раз, Вікіпедія. Симетрія очевидна, та вісь балджу 3000 LY! Спостерігайте далекі в профіль. Хто покаже синхронність джетів одержить пів Нобеля з Метром ДеЛЕ©. За Інь-Ян Тиск-Пустка Виру.

It looks like a wolf-rayet star.🤔

Wrong, professor Rather, the lights of the star. God Almighty said: فَإِذَا انشَقَّتِ السَّمَاءُ فَكَانَتْ وَرْدَةً كَالدِّهَانِ (37) What is meant by the sky: a star.

You're looking at the longest X-ray timelapse of a supernova ever captured. In 1604, a brilliant new star suddenly blazed in the night sky, surpassing Jupiter in brightness for weeks. This spectacle marked the explosive death of a white dwarf in a Type Ia supernova—one of the universe's most energetic cataclysms. Over 400 years later, astronomers continue to observe its expanding aftermath. Drawing on 25 years of X-ray observations from NASA’s Chandra X-ray Observatory (spanning 2000 to 2025), scientists have created the longest-ever X-ray timelapse of Kepler’s Supernova Remnant. This glowing shell of debris, located about 17,000 light-years away in our Milky Way, appears as it plows through interstellar space. The remnant expands unevenly: the lower edge races outward at up to 13.8 million miles per hour (22.2 million km/h)—roughly 2% the speed of light—while the upper regions move more slowly, around 4 million miles per hour (6.4 million km/h), due to encounters with denser surrounding gas. These asymmetries allow researchers to map the pre-explosion environment and refine models of the blast itself. Beyond destruction, such supernovae enrich the cosmos by forging and dispersing heavy elements essential for forming new stars, planets, and ultimately, life. Through enduring missions like Chandra, we gain a front-row view to these ancient events, revealing how the echoes of stellar deaths persistently sculpt the evolving universe.
