The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.

Gravitational lensing is a dramatic example of Einstein’s general theory of relativity in action. A celestial body such as a galaxy cluster is sufficiently massive to distort spacetime, which causes the path of light around the object to be visibly bent as if by a vast lens...

Researchers have found a possible explanation as to why higher breast density and older age increases the risk of breast cancer.

In an innovative study, researchers at the Turku Bioscience Centre, InFLAMES Flagship of the University of Turku, and Turku University Hospital, Finland, have made an extraordinary discovery that turns conventional wisdom on its head...

A University of Minnesota Twin Cities team has, for the first time, synthesized a thin film of a unique topological semimetal material that has the potential to generate more computing power and memory storage while using significantly less energy. The researchers were also able to closely study the material, leading to some important findings about the physics behind its unique properties.

The study is published in Nature Communications.

As evidenced by the United States’ recent CHIPS and Science Act, there is a ...

Massive stars refer to stars that are more than ten times the mass of the sun. They can release powerful ultraviolet radiation, ionize the gas in the interstellar medium, and eventually produce the elements necessary for the birth of life through spectacular supernova explosions...
