Tiny Earth-based telescopes just did the impossible: they captured the first light of the universe, offering a new look at our cosmic origins.

Cosmic Joust Reveals Quasar’s Power to Kill Star Formation

Astronomy & Astrophysics Ryan Kessler -
Astronomers have captured a galactic “joust” 11 billion light-years away. One galaxy wields a quasar like a weapon, blasting its opponent and halting star formation—a cosmic clash with lasting implications.

How Massless Particles May Have Transformed into Dark Matter

Cosmology Ryan Kessler -
A Dartmouth theory suggests dark matter was born when light-speed particles suddenly condensed and became heavy—leaving a mark we might soon detect.

When the Universe Wiggles

Astronomy & Astrophysics Ryan Kessler -
A new study proposes a groundbreaking way to detect gravitational waves — by watching distant quasars “wiggle” in the sky — potentially unlocking the three-dimensional nature of spacetime ripples and rewriting what we know about gravity.
