Physicists Test if Dark Energy is a Mathematical Illusion

A niche group of cosmologists argues that dark energy may not exist, claiming that the universe's accelerating expansion is a result of flawed assumptions in General Relativity regarding homogeneity. While mainstream models attribute 70% of the universe's energy to this mysterious force, critics like David Wiltshire suggest that gravity’s effect on time in clumpy regions creates an illusion of acceleration. New simulations and the Euclid telescope aim to test these theories, though current data suggests the standard model remains largely accurate.

Euclid Discovers 31 Ancient Quasars, Revealing Fast-Growing Black Holes in the Early Cosmos

ESA’s Euclid space telescope found 31 ancient quasars dating to redshift 6.6–7.8, including two record-holders at z=7.77 and z=7.69, making them the oldest seen. Each hosts a billion-solar-mass black hole, existing when the universe was under a billion years old. The haul doubles the known number of such quasars and demonstrates Euclid’s unexpected capability to census the early cosmos, though how these enormous black holes formed so quickly remains a major puzzle. This is just the first major result from a six-year survey that could uncover many more distant quasars.

Euclid finds two ancient quasars, each shining with a trillion suns

The European Space Agency's Euclid space telescope has spotted 31 newly identified quasars dating to the universe's first 770 million years, including the two oldest known at redshifts 7.77 and 7.69, each radiating about a trillion suns. The discoveries, published in Astronomy & Astrophysics, double the number of quasars known from that era and shed light on how supermassive black holes formed so rapidly after the Big Bang. Euclid's wide-field survey will uncover hundreds more, helping create the largest 3D map of the universe and revealing how early galaxies and black holes evolved.

Milky Way’s Core Revealed by Euclid, Hinting at a Galaxy Teeming with Exoplanets

The European Space Agency’s Euclid telescope captured nine visible-light images of the Milky Way’s center over 26 hours, revealing about 60 million stars in a patch the size of a full Moon; although built to study dark matter and dark energy, its microlensing observations could map tens of thousands to hundreds of thousands of exoplanets across the galaxy, signaling a new era of exoplanet discovery alongside other space telescopes.

Euclid Captures the Milky Way's Crowded Core in Unprecedented Detail

The European Space Agency’s Euclid space telescope produced the largest, most detailed visible-light image of the Milky Way’s center—the galactic bulge—showing more than 60 million stars in a mosaic of nine pointings. While no new microlensing events were identified during the 26-hour campaign, the data will enable precise mass measurements of known exoplanets and serve as a reference archive for future missions like NASA’s Roman telescope, supporting deeper exoplanet studies, brown dwarfs, binary stars, and galactic dust research.

Euclid reveals 60 million stars in unprecedented Milky Way center view

ESA’s Euclid telescope produced a 26‑hour mosaic of the Milky Way’s bulge, unveiling more than 60 million stars in the central region and enabling precise stellar motions to improve exoplanet detection via microlensing; the work complements NASA’s upcoming Roman telescope, which is expected to find about 1,500 microlensing planets and could push the galactic exoplanet count beyond 100,000.

Unveiling the Secrets of Einstein Rings and Cosmic Lenses

A nearby galaxy, NGC 6505, was found to contain a complete Einstein ring, revealing new insights into the galaxy's mass distribution, dark matter content, and stellar population, thanks to high-quality imaging from the Euclid telescope and follow-up spectroscopy. This discovery enhances understanding of galaxy cores and demonstrates Euclid's potential for future cosmological studies.

"Euclid Telescope Unveils More Rogue Planets"

The Euclid space telescope has discovered seven new rogue planets, adding to the growing evidence that there could be trillions of these starless worlds in the Milky Way. These planets, which exist in perpetual night, may still have the potential to host life. The findings suggest a close connection between star and planet formation, and future missions like NASA's Roman space telescope are expected to uncover even more rogue planets.

"ESA's Euclid Telescope Unveils Five Stunning Deep Space Images"

The Euclid telescope has captured a stunning image of over 50,000 galaxies, primarily in the Abell 2390 cluster and the Orion Nebula, revealing new insights into the universe's formation. The European Space Agency's project aims to create a 3D map of the Milky Way, and the telescope's high-resolution capabilities have uncovered millions of objects, some dating back to the first billion years after the Big Bang. Scientists believe these galaxies are surrounded by dark matter, and further study could provide significant information about planet formation.
