JWST observations reveal perplexing "little red dots," impossibly large black holes, and unexpectedly bright galaxies in the early universe, challenging existing astrophysics. Scientists are developing new theories, including black hole stars and super-Eddington accretion, to explain these cosmic enigmas.
The Vera C. Rubin Observatory in Chile has released a stacked image of the COSMOS field, containing over 500,000 galaxies and 50,000 stars. Captured by the 3.2-gigapixel LSST Camera, this image, part of the Early Data Preview 2, offers the clearest view yet of this crucial region for studying the universe's history.
Researchers identified the source of mysterious repeating radio signals from space. A global map of the fungal network supporting plant life and climate regulation was created. The Euclid space telescope captured a detailed image of the Milky Way's center. A new fossil axolotl species was found in Mexico. Earthquakes in Mexico, Norway, and Venezuela were documented, with seismic activity linked to sports victories and seismic doublets. Satellite imagery revealed the impact of Venezuelan earthquakes and how space lasers can track crustal shifts.
Le télescope spatial Euclid a identifié 31 quasars, dont les deux plus anciens connus, datant d'environ 670 millions d'années après le Big Bang. Ces découvertes interrogent les scientifiques sur la formation rapide des trous noirs supermassifs dans l'univers primitif.
ESA's Euclid telescope has identified two of the most ancient quasars, dating back to when the universe was only 670 million years old. This discovery significantly increases the number of known ancient quasars, offering new insights into the early universe.
Astronomers using Hubble and James Webb telescopes found light from MXDFz4.4, a tiny galaxy from the early universe. This galaxy, existing shortly after the Epoch of Reionization, shows powerful ultraviolet light escaping, offering a rare glimpse into cosmic transformation.
A Chinese survey shows over 96% awareness and 54% usage of AI, with 40% using it in daily life, work, or study. In contrast, US Gen Z workers express concerns about AI threatening jobs and devaluing degrees.
A global team led by CSIRO has created the largest-ever map of cosmic magnetic fields by measuring light from nearly 4 million galaxies. The "SPICE_RACS" map, made possible by the ASKAP radio telescope in Western Australia, will help scientists investigate fundamental questions about the universe's magnetic origins and evolution.
Cosmic voids, vast regions of space mostly devoid of matter, are becoming crucial for understanding the universe's biggest mysteries, including dark energy and the Hubble tension. New telescopes and simulations are enabling scientists to study these 'cosmological laboratories' with unprecedented clarity.
