Two new brown dwarfs discovered with TESS
An international team of astronomers reports the detection of two new brown dwarfs orbiting distant stars using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound objects are about 30 times more massive than ...
Quantum genesis: The emergence of a flat universe and its mirror from nothing
I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe emerging from an infinitely ...
JWST captures its first direct images of carbon dioxide outside solar system
The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation ...
