Scientists using the James Webb Space Telescope have discovered nine unusual 'platypus galaxies' that challenge traditional classifications, as they exhibit a mix of features unlike typical galaxies, possibly representing a new type of early universe galaxy or a new stage in galaxy evolution.
Strange cosmic objects observed by the James Webb Space Telescope may be young 'platypus' galaxies or a new class of active galactic nuclei, providing insights into galaxy formation in the early universe. These objects exhibit mixed features of stars and galaxies, challenging existing classifications and hinting at unique formation processes.
Astronomers have discovered a new celestial object called 'Cloud 9,' a starless, gas-rich dark matter hydrogen cloud near galaxy Messier 94, which provides insights into dark matter and early universe formation. This is the first confirmed existence of such an object, offering a glimpse into primordial galaxy building blocks and the dark universe.
Scientists using NASA's James Webb Space Telescope have identified a unique group of tiny, point-like galaxies from 12 to 12.6 billion years ago that defy current classification, resembling a cosmic 'platypus' due to their unusual combination of features, and raising questions about early galaxy formation.
A new super simulation called FLAMINGO reveals that the universe's observed galaxy clustering is smoother than predicted by standard models, intensifying the ongoing S8 tension in cosmology, which questions whether current theories or measurements need revision.
On the fourth anniversary of the James Webb Space Telescope, ESA released a compilation of stunning cosmic views, showcasing its exploration of nebulae, star nurseries, and distant galaxies, highlighting its ongoing mission to explore the universe.
A stunning image captured by the James Webb Space Telescope shows two spiral galaxies, NGC 2207 and IC 2163, in the midst of a slow-motion collision, revealing details of star formation and cosmic interactions through infrared and X-ray observations.
The James Webb Space Telescope has released a stunning image revealing a dense cluster of galaxies and cosmic filaments in the early universe, providing new insights into galaxy formation, the structure of the cosmic web, and the influence of dark matter and dark energy, with observations reaching back over 13 billion years.
The universe, originating from the Big Bang about 14 billion years ago, is expected to continue expanding, with star formation ceasing and galaxies merging into larger elliptical galaxies over trillions of years. Ultimately, the universe may fade into darkness, driven by dark energy, but its exact future remains uncertain and open to new discoveries.
Astronomers analyzing data from the Euclid telescope and Herschel mission have concluded that the universe's star formation has peaked and is now declining, with galaxies gradually cooling down, suggesting the universe is becoming 'colder and deader' over billions of years.
To celebrate the 35th anniversary of the Hubble Space Telescope, a gallery of its most iconic images is showcased, highlighting its contributions to astronomy, including detailed views of galaxies, nebulae, and cosmic phenomena, as well as its technological evolution and discoveries over the decades.
The universe has been expanding for nearly 14 billion years, driven by dark energy since about 6 billion years ago. While cosmic structures like galaxies and clusters are gravitationally bound and do not expand, the space between these bound systems continues to grow, leading to an ever-expanding universe where only isolated 'islands' of matter remain gravitationally bound within the vast cosmic voids.
Astronomers have discovered the most powerful and distant 'odd radio circle' (ORC), featuring a rare twin-ring structure, which may be linked to superwinds from host galaxies, providing new insights into galaxy and black hole evolution.
Astronomers have discovered the most distant and powerful odd radio circle (ORC) to date, featuring a rare twin-ring structure that may be linked to superwinds from host galaxies, providing new insights into galaxy and black hole evolution.
Astronomers, with the help of citizen scientists, have discovered the most powerful and distant 'odd radio circle' (ORC) to date, featuring a unique double-ring structure that may be shaped by super winds from spiral galaxies, providing new insights into galaxy and black hole co-evolution.
