For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates ...
Three young stars have been kicked out of their cosmic nursery, perhaps for engaging in a gravitational brawl, according to Hubble Space Telescope scientists, who released images of the trio on ...
A cosmic explosion known as GRB 250702B is by far the longest gamma-ray burst astronomers have ever seen—if it’s even one at ...
