Earth bears the scars of nearby supernovae through traces of unique isotopes like iron-60 and plutonium-244, found in sediments and lunar samples. These cosmic remnants,…

This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble…
The collision of two vast galaxy clusters, including El Gordo, challenges the predictions of the Lambda-cold dark matter (ΛCDM) cosmological model, suggesting a need to…
Researchers have discovered a method to potentially detect and measure dark energy by examining the motion between the Milky Way and Andromeda galaxies. This technique,…

A new study amplifies the Hubble tension, a discrepancy in cosmic expansion rate measurements, by providing the most accurate calibration of Cepheid stars for distance…

Researchers have used simulations to investigate the cosmic web, the filamentary pattern of galaxies that exists on large scales throughout the universe. By treating the…
Antimatter is matter made up of the antiparticles of the corresponding particles found in “ordinary” matter. Physicists invoke the cosmological collider to demonstrate why matter, not antimatter, dominates the…
The currently most widely accepted theory about the Moon’s origins is the “giant-impact” theory. It proposes that the Moon was created by Earth colliding with…

Extremely fast radio signals from a surprising source. A cluster of ancient stars (left) close to the spiral galaxy Messier 81 (M81) is the source…
A study by the University of Bonn: Observations fit poorly with the Standard Model of Cosmology. The Standard Model of Cosmology describes how the universe…
Centaurus A is an elliptical galaxy located about 13 million light-years from Earth. This color composite image reveals the lobes and jets emanating from the…
Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions – one of their tried-and-true tools for studying the mysterious…
The team’s analysis paves the way for better measurements in the future using telescopes from the Cherenkov Telescope Array. Credit: Daniel López/IAC Clemson team collaborates…
A star known as S0-2 (the blue and green object in this artist’s rendering) made its closest approach to the supermassive black hole at the…
