James Webb’s “too massive” galaxies may be even more massive

The first results from the James Webb Space Telescope have hinted at galaxies so early and so massive that they are in tension with our understanding of the formation of structure in the Universe.

Nearby galaxies help astronomers understand distant galaxies

In a newly published study researchers show how the amount of light that escapes from a galaxy is connected to its physical properties. The result has implication for how we interpret observations of galaxies in the…

First ever asteroid hit by spacecraft could save the Earth from impact

Humanity’s first attempt to re-direct asteroids that could collide with Earth, the NASA Double Asteroid Redirection Test satellite (DART), successfully impacted the 150 meter large moon Dimorphos orbiting the 760 m…

The brightest explosion ever seen

A particularly bright Gamma-ray burst was recently detected by several space telescopes, and a team of scientists led by astronomers at the Cosmic Dawn Center measured the exact distance to the burst.
