Canadian Researchers Map the Milky Way's Magnetic Field February 6, 2026
An international team of researchers have published two papers that reveal a new model for how the magnetic field of the Milky Way evolved.
The Collaboration that Brought you the First Image of a Black Hole Just Released Photos of its Massive Jet February 6, 2026
Recently published data from the Event Horizon Telescope (EHT) of the galaxy Messier 87 facilitate new insights into the direct environment of the central supermassive black hole. Measured differences in the radio light on different spatial scales can be explained by the presence of an as of yet undetected jet at frequencies of 230 Gigahertz […]
Is the Universe Older Than We Think? Part 4: The Changing Lambda-scape February 6, 2026
Isn’t the FLRW metric way generic? It lays out the basic assumptions and tells us how the universe should behave, but it doesn’t say WHAT the universe is made of.
The Dirty Afterlife of a Dead Satellite February 6, 2026
Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase […]
The "Little Red Dots" Observed by Webb Were Direct-Collapse Black Holes February 5, 2026
The discovery by JWST of a substantial population of compact "Little Red Dots" (LRDs) presented astronomers with a major mystery. By reproducing their spectra with simulations, a team argued that they were Direct Collapse Black Holes (DCBHs).
