Astrophysicists have tried to calculate how long the universe has existed by measuring time elapsed since the Big Bang and evaluating the oldest stars at high redshifts of light from other galaxies.
The Perseverance landed at the Jezero crater in 2021, an area in the planet's northern hemisphere that once was flooded with water and home to an ancient lake basin.
Researchers said the gamma-ray burst they observed may have been caused by the collision of two compact stars in the densely packed and chaotic environment.
The organic molecules found in this distant galaxy are not signs of life. Found via NASA's James Webb Space Telescope, their discovery raises questions about star formation.
A new theoretical model made by Israeli astrophysicists reveals an excess of massive galaxies, in contrast to previously accepted theories.
Humanity has been looking for aliens for decades but has yet to find any evidence. A new study suggests we may just be in a sort of cosmic blind spot for alien radio signals.
A mysterious trail of stars puzzled scientists for some time. While a theory posited this to be a supermassive black hole passing through a gas cloud, a simpler theory has now emerged.
Contrary to previous beliefs that the quasars are formed at the peak of galactic collision, researchers found that they are actually formed during the initial stages of collision.
The observation is among the first of a distant galaxy using NASA's James Webb Space Telescope since it was launched in December 2021.
Cassiopeia A is the youngest known supernova remnant in the Milky Way Galaxy. NASA's James Webb Space Telescope was able to view it in greater detail than previous observations.
