Scientists propose a revolutionary theory suggesting supermassive black holes observed by the James Webb Space Telescope originated not from dying stars, but as tiny primordial black holes formed in the Big Bang’s aftermath. This challenges our understanding of black hole formation and the early universe.
The James Webb Space Telescope (JWST) has unearthed a peculiar galaxy, JADES-GS+53.18343−27.79097, existing just 700 million years after the Big Bang. This galaxy exhibits an unconventional growth pattern, forming stars faster on its outskirts than in its dense core, defying the traditional understanding of galaxy development. This discovery, detailed in Nature Astronomy, confirms theoretical models predicting the existence of such ‘inside-out’ galaxies during the early universe, opening a window into the mysteries of cosmic evolution.
Westerlund 1, a super star cluster located 12,000 light-years away, is a cosmic spectacle captured in stunning detail by the James Webb Space Telescope. This galactic factory, teeming with massive stars and illuminating the Milky Way’s past, offers unprecedented insights into the birth and death of stars.
The James Webb Space Telescope (JWST) has discovered a peculiar galaxy in the early universe where the gas is brighter than the stars. This galaxy, dubbed GS-NDG-9422 (9422), is thought to be a potential missing link in galactic evolution and provides insights into the types of stars that formed in the early universe.
The James Webb Space Telescope has turned its powerful gaze toward the Milky Way’s extreme outer edge, revealing stunning details of star-forming regions and the chaotic behavior of nascent stars. The observations highlight the unique characteristics of these distant regions, offering new insights into the galaxy’s early history and the diverse processes of star formation.
A new James Webb Space Telescope (JWST) image reveals a captivating cosmic ‘smile’ formed by two interacting galaxies, Arp 107. The image highlights the power of infrared observation, revealing details invisible to the human eye and showcasing the intricate dance of these celestial objects.
The James Webb Space Telescope has captured a breathtaking image of Arp 107, two galaxies in a dramatic collision 465 million light-years away. The image showcases the chaotic beauty of galactic interaction, highlighting the birth of new stars and the swirling dust and gas around a supermassive black hole.
Recent observations have thrown the well-established standard model of cosmology into question, leading to heated debates about the nature of dark energy and dark matter. The Hubble tension, S8 tension, and unexpected properties of early galaxies have challenged the model’s fundamental assumptions. While more data is needed to resolve these issues, the future holds exciting possibilities for a paradigm shift in our understanding of the universe.
The James Webb Space Telescope has captured an image of a cosmic question mark formed by gravitational lensing, a phenomenon where the gravity of a massive object distorts the light from objects behind it. This rare configuration provides valuable insights into the early universe and the formation of galaxies.
Astronomers using the James Webb Space Telescope have discovered a strange new class of galaxies, dubbed ‘Little Red Dots,’ that are incredibly compact and red. These galaxies, unlike anything seen before, are defying current understanding, potentially being either extremely dense star clusters or hosting oversized black holes.
