The disparity in quasar fields introduces a kink in the standard picture of black hole growth and galaxy formation. According to physicists’ best understanding of how the first objects in the universe emerged, a cosmic web of dark matter should have set the course. Dark matter is an as-yet-...
The universe is undeniably vast, and from our perspective, it may seem like Earth is in the middle of everything. But is there a center of the cosmos, and if so, where is it? If the Big Bang started the universe, then where did it all come from, and where is it going? To start...
of electromagnetic energy, these are channeled through cables to the back of the brain, augmented by other locations that are as vast and labyrinthine as the Milky Way. This, according to the texts, is where the actual colors, shapes, and movement "happen." This is where they'...
The beautiful stars in the Milky Way lead people to such questions. This notion is tied in with other philosophical puzzles such as the origins of the universe and the meaning of life. Many cultures have myths of beings who come from outer space. This reflects our interest, as humans, in...

The origin of cosmic rays, the particles with the highest energy in the universe, has been a great mystery since their discovery in 1912. Because cosmic rays promote the chemical evolution of interstellar matter, understanding their origin is critical in understanding the evolution of our Galaxy. ...
Several emerging links between high-redshift observational cosmology, and the Galactic fossil evidence found in the kinematics, metallicities and ages of Milky Way stars are discussed. In a flat Cold Dark Matter model with Ω ≃ 0.3 that agrees with present large-scale structure observations, ...
What is the great silence theory? The "great silence" is the idea that there is no evidence of extraterrestrial civilizations and that we are truly alone in the universe; it is also known as the Fermi Paradox. Are we truly alone in the cosmos? (Image credit: Created in Canva Pro by...
