Discoveries concerning the orderly nature of the universe on large scales such as origin, fate, other universes, infinity, space and time.
Black Holes and Galaxies Coexisted In Early Universe
Black holes and galaxies existed together during the first one percent of our universe’s existence. Find out why this upends conventional thinking on how stars, galaxies and black holes formed after the Big Bang.
Heaviest Chemical Elements Created by Ancient Stars
The heaviest chemical elements in the universe come from neutron stars. Find out how a new study shows that this process creates heavier atoms than anything we experience on Earth.
Galaxy Without Dark Matter Challenges Current Science
A galaxy without dark matter has come to light in the constellation Perseus. Find out why this poses a puzzle for astronomers and challenges cosmology's explanation of how our universe began.
Hawking Evaporation Means Everything Will Eventually Dissipate
A new study has found that Hawking evaporation can take place beyond the range of a black hole’s event horizon. Find out why this means that everything in the universe will eventually evaporate.
Massive Early Galaxies Discovery Could Be ‘Universe Breaker”
Massive early galaxies emerged from a review of the James Webb Space Telescope’s first dataset. Find out why current science says they shouldn’t exist, and what this means for our understanding of the Big Bang and galaxy formation.
Dark Energy Measured More Precisely than Ever
Dark energy is the term scientists use to describe the cause of the accelerated expansion of the universe. Find out how a new analysis provides its most precise measurement yet.
Dwarf Galaxies Contradict Dark Matter Paradigm
Dwarf galaxies contain less than ten percent of the stars in the Milky Way. Find out how their behaviour in a region called the Fomax Cluster challenges dark matter's existence.
Galaxies Without Dark Matter Might Form From Collisions
Galaxies without dark matter are rare and were once thought impossible. Find out how a new hypothesis about their formation may explain how all galaxies form and what dark matter is.
Cosmic Queries – A Review
Cosmic Queries is a new book written by Neil DeGrasse Tyson and James Trefil and published by National Geographic. Find out how this book balances education and entertainment in a highly readable volume.
