Ralf Kaehler/SLAC National Accelerator Laboratory One of the great unknowns of nearly the past one hundred years is the identity of the invisible stuff that makes up the bulk of the matter in our galaxy and others. Called dark matter, this stuff can exert...

Image Credit: APS/Alan Stonebraker Pairs of objects are responsible for some of the coolest phenomena in our universe, and while a lot of these pairs end up merging into a single object given enough time, there are a few… theoretically at least… that the universe...

JWST initially identified these three objects (JADES-GS-z13-0, JADES-GS-z12-0 and JADES-GS-z11-0) as galaxies in December 2022. Now a team suggests they might be “dark stars,” theoretical objects powered by particles of dark matter annihilating. Credit: NASA/ESA We...

This deep galaxy field from Webb's Near-Infrared Camera shows an arrangement of 10 distant galaxies (white circles) in a diagonal. NASA, ESA, CSA, Feige Wang/University of Arizona and Joseph DePasquale/STScI Currently, a lot of the research we see coming from JWST is...

Before we go to break, I want to highlight one more piece of news. In a new paper in the journal Nature Astronomy, researchers Geraint Lewis and Brendon Brewer show evidence for time appearing to tick slower in the early universe. According to relativity, as our...
