The Very Early Stage
2021年4月13日 日常“With these observations, we are pushing back the limit of the observable universe and, therefore, we are coming closer to the cosmic dawn,” University College London astronomer Nicolas Laporte said, adding that computer simulations suggest that the first stars appeared around 150 million China led Tri proof lights factory years after the Big Bang.
“Prior to our study, there were only theoretical predictions of the earliest star formation.Astronomers provides insight into star formation in perhaps the most distant galaxy ever observed.The researchers confirmed the distance of the galaxy with observations from ground-based telescopes in Chile and reconstructed the earlier history of MACS1149-JD1 using infrared data from orbiting telescopes.9 trillion miles (9. The scientists viewed the galaxy, called MACS1149-JD1, as it existed roughly 550 million years after the Big Bang, which gave rise to the universe about 13.
The study marked another step forward as scientists hunt for evidence of the first stars and galaxies that emerged from what had been total darkness in the aftermath of the Big Bang, a time sometimes called “cosmic dawn. A light-year is the distance light travels in a year, 5.The scientists viewed the galaxy, called MACS1149-JD1, as it existed roughly 550 million years after the Big Bang, which gave rise to the universe about 13. We have for the first time observed the very early stage of star formation in the universe,” said astronomer Takuya Hashimoto of Osaka Sangyo University in Japan.Light emitted by MACS1149-JD1 travelled 13.

Their research, published on Wednesday, provides insight into star formation in perhaps the most distant galaxy ever observed.5 trillion km).8 billion years ago.28 billion light years before reaching Earth.The presence of oxygen showed that an even earlier generation of stars had formed and died in MACS1149-JD1 and that star formation in that galaxy began about 250 million years after the Big Bang when the universe was only about 2 percent of its current age, the researchers said. The oxygen in MACS1149-JD1 was the most distant ever detected.
