NASA's newest space telescope rocketed into orbit Tuesday to map the entire sky like never before—a sweeping look at hundreds of millions of galaxies and their shared cosmic glow since the beginning of time.
Astronomers have revealed new evidence that not just one, but four tiny planets are circling around Barnard's Star, the second-nearest star system to Earth.
In the ALMAGAL project, an international research team will analyze observations of more than a thousand "star factories" to better understand the origin and formation of new stars. Most previous studies have focused on the ...
The universe is ballooning outward at an ever-faster clip under the power of an unknown force dubbed dark energy. One of the major goals for NASA's upcoming Nancy Grace Roman Space Telescope is to help astronomers gather ...
A new study by Rice University researchers Sho Shibata and Andre Izidoro presents a compelling new model for the formation of super-Earths and mini-Neptunes—planets that are 1 to 4 times the size of Earth and among the ...
A discovery made by a team led by researchers at the University of Michigan tugs at the seams of some key cosmic lessons we thought we had learned from our own galaxy.
Rotating black holes are the most powerful phenomenon in the known universe. Their powerful gravity radically alters the curvature of spacetime around them, leading to relativistic effects like time dilation, light distortion, ...
University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old—just 2% of its current age.
A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark matter.
The Flame Nebula, located about 1,400 light-years away from Earth, is a hotbed of star formation less than 1 million years old. Within the Flame Nebula, there are objects so small that their cores will never be able to fuse ...
