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 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 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.
Hubble tension is the difference in results that scientists get when they try to measure the rate at which our Universe expands. Find out how a new study may have split the difference and loosened the tension between two camps of researchers. (4:00 min read)
Dark energy is a hypothetical force that scientists rely on to explain why the Universe expands at an accelerating rate. Discover how a new theory challenges dark matter’s existence based on magnetism. (4:30 min read)
Lost in Math is Sabine Hossenfelder's book challenging physicists' preference for elegant theories over experimental results. Discover how this can lead to dead end research that misleads the public.(5:30 min read)
The Universe’s expansion rate, the Hubble constant, is vital to understanding the Cosmos’ origin and fate. Discover how the latest technique for measuring the Hubble constant sheds new light on the past and future. (5:15 min read)
Gravitomagnetism is the energy created by spinning objects in the fabric of spacetime. Discover why it may explain away the mysterious Dark Matter for which scientists have been searching unsuccessfully. (4:30 min read)
The Last Journey Simulation used Mira, one of the world’s most powerful supercomputers, to model how mass flows through our Universe. Discover how it breaks ground for future cosmological studies.(4:00 min read)
