Dark Energy

The Vera C. Rubin Observatory, housing the largest digital camera ever built, has begun a decade-long survey of the southern sky from a Chilean mountaintop. The project aims to map billions of stars and galaxies, study dark matter and dark energy, and capture repeated images to detect faint celestial objects.

A new AI-powered framework is set to enhance astronomers' ability to measure the Universe's expansion by analyzing Type Ia supernovae with high accuracy. The method is tailored for data from the upcoming Vera C. Rubin Observatory and aims to improve understanding of dark energy.

Euclid has captured the most detailed photo yet of the Milky Way's heart as part of a mission to map one-third of the sky. The mission aims to investigate the mysteries of dark matter and dark energy.

Dark energy is still accelerating the expansion of the universe, and astronomers are relieved. They express gratitude for having averted a potential crisis related to cosmic expansion.

The article explores the possibility of a dark dimension connecting dark energy and dark matter, which together account for approximately 95% of the universe. Dark energy, making up about 70%, drives cosmic expansion, while dark matter, comprising 25%, helps maintain galaxy structure.

A new theoretical study suggests that collapsing massive stars might create tiny new universes driven by dark energy, forming exotic objects called gravastars instead of black holes. The collapse could generate a miniature cosmos that expands and resists gravitational collapse.

Season Five of 'The Joy of Why' explores bold scientific questions, including the future of CRISPR gene editing, AI's impact on mathematics, the search for extraterrestrial civilizations, and potential misunderstandings about dark energy. Mathematician Steven Strogatz and physicist Janna Levin return as hosts.

The article explores the origins of stars and light, and questions whether dark energy, a hidden sector of particles and forces, influences the cosmos.

The mystery of dark energy may be shed light on by 'cannibal stars,' AI and the Rubin Observatory. This phenomenon involves a white dwarf star feeding on a stellar companion prior to a Type 1a supernova. The study of these events could provide insights into dark energy.

Scientists have completed the largest high-resolution 3D map of the universe using data from 47 million galaxies and quasars, potentially revealing new insights into dark energy. The DESI collaboration overcame challenges like wildfire disruptions to create this dataset, which suggests dark energy may behave unexpectedly.

Scientists are investigating why the Universe behaves differently on massive scales compared to the solar system, with theories pointing to dark energy or a hidden 'fifth force'. Observations of distant galaxies suggest gravitational anomalies not seen locally, where Einstein's laws remain consistent.

Researchers have created a massive 3D map of dark energy using DESI, with Earth at the center and each point representing a galaxy. This map is being used to study the mysterious force of dark energy.

Researchers have created the most comprehensive 3D map of the universe using DESI's tool, enabling detailed study of dark energy. The map centers on Earth with each point representing a galaxy, marking a significant advancement in cosmological research.

The DESI collaboration completed a high-resolution 3D map of the Universe, offering new insights into dark energy's potential variability. The map, built using advanced spectroscopic techniques, may help confirm or refute earlier hints of time-varying dark energy properties.

Scientists have found the universe's expansion rate to be faster than predicted, yet the cause remains unknown. This discovery challenges existing cosmological models and highlights a major unresolved mystery in astrophysics.
