Using data from NASA’s James Webb Space Telescope, astronomers have produced the most detailed map of the cosmic web ever made.

The universe has been having fewer and fewer stellar "babies". Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here's the twist: the most essential "fuel" for making stars has barely decreased.

Astronomers in Sweden have found evidence of exocomets – comets in other solar systems – orbiting a young star similar to our Sun. The observations point to a possible mechanism for how water might be transported from the cold outer regions of the planetary system to regions where planets form.
