Gamma ray hide & seek

A new study suggests that most gamma radiation reaching Earth is leftover energy from massive shock waves caused by gravitational forces. The collision of electrons with low-energy photons could be a sign of ordinary matter captured within intergalactic clouds, shedding light on the 'missing matter' puzzle.

Cosmic pressure fronts mapped by Chandra

Scientists have imaged the pressure fronts in a colossal cosmic 'weather system' produced by the collision of two giant clusters of galaxies. The data reveals a bright but relatively cool central region embedded in a large cloud of hot gas. This is the first detailed look at the late stages of this merger process.

Big Bang Theory Challenged

An Australian-led team of astronomers has discovered a significant number of stray stars, potentially altering our understanding of the universe's composition. These findings suggest that there may be as many stars living in intergalactic space as those within galaxy clusters.

NYU Physicist Proposes New Theory For Origin And Make-Up Of Extremely High-Energy Cosmic Rays

Physicist Glennys Farrar proposes that extremely high-energy cosmic rays come from distant quasars, violating the Greisen-Zatsepin-Kuzmin cutoff. She suggests a new subatomic particle, the SO, with neutral and gluon-bound properties, as an alternative explanation.

Astronomers, Using New Method, Find Evidence For Missing Matter

Researchers have found evidence of a 'missing' form of ordinary matter, known as baryonic matter, that was thought to be needed to form the cosmos billions of years ago. The findings suggest that this matter was spread throughout intergalactic space in a diffuse gas of hydrogen and helium atoms.

New Gamma-rays Count Challenges Astronomical Theories

A team of astrophysicists discovered fewer low-energy photons in the universe than previously thought, suggesting that high-energy gamma rays may not be interacting with as many low-energy photons as expected. This observation could alter current theories of the history of the universe and galaxy formation.
