While analyzing data from the first images of a well-known early galaxy taken by NASA's James Webb Space Telescope (JWST), Cornell University astronomers discovered a companion galaxy previously hidden behind the light of the foreground…

Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe. "These objects are way more massive? than anyone expected," said Joel Leja, assistant…

Something unexpected was discovered by astronomers as they peered back in time to the early days of the universe using the James Webb Space Telescope. According to a new study published in the journal Nature on Wednesday, the discovery of…

In a new study, an international team of astrophysicists has discovered several mysterious objects hiding in images from the James Webb Space Telescope: six potential galaxies that emerged so early in the universe’s history and are so…

Observations by NASA's James Webb Space Telescope are upending the understanding of the early universe, indicating the presence of large and mature but remarkably compact galaxies teeming with stars far sooner than scientists had considered…

It is a popular notion that aside from large celestial objects like planets, stars and asteroids, outer space is empty. In fact, galaxies are filled with something called the interstellar medium (ISM) -- that is, the gas and dust that…

Roughly 500 million light-years away, near the constellation Delphinus, two galaxies are colliding. Known as merging galaxy IIZw096, this luminous phenomenon is obscured by cosmic dust, but researchers first identified a bright, energetic…

Thanks to the James Webb Space Telescope's first images of galaxy clusters, researchers have, for the very first time, been able to examine very compact structures of star clusters inside galaxies, so-called clumps. In a paper published in…

An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn" -- the era after the Big Bang when stars first ignited and galaxies began to bloom. In a paper accepted for publication in The…
