How would it feel to peer into the night sky and behold millions of galaxies across a vast swath of space? What would it be like to hunt for worlds beyond our solar system, or spot the fiery deaths of stars?
Do constants of nature—the numbers that determine how things behave, like the speed of light—change over time as the universe expands? Does light get a little tired traveling vast cosmic distances? It was believed that ...
As predicted by the theory of general relativity, the passage of gravitational waves can leave a measurable change in the relative positions of objects. This physical phenomenon, known as gravitational wave memory, could ...
An international research group led by the Italian National Institute for Astrophysics (INAF) and comprising 34 research institutes and universities worldwide utilized the Near-Infrared Spectrograph (NIRSpec) on board the ...
This new picture of the month from the NASA/ESA/CSA James Webb Space Telescope features the gravitational lensing of the quasar known as RX J1131-1231, located roughly six billion light-years from Earth in the constellation ...
A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary "guest star," now labeled supernova (SN) 1181, which was recorded ...
One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly ...
A small team of astronomers from Yunnan University, the University of Utah, New Mexico State University, and the University of St Andrews has created a new model of the Milky Way galaxy based on the results of their census ...
Using NASA's Chandra X-ray spacecraft, astronomers from the University of Alabama in Huntsville have observed a merging galaxy cluster known as SPT-CLJ 2031-4037. They detected a rarely seen strong shock front in this galaxy ...
A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single ...
