For more than a decade, a massive star in a distant galaxy has been putting on a spectacular show, repeatedly erupting as if it were about to explode and die – an act that has earned it the nickname “supernova impostor.” Now, astronomers have discovered what may be driving those outbursts: a hidden companion, either a neutron star or a black hole, that’s pulling material away from the star. 

University of Virginia astronomer is leading a team taking the first direct measurement of the length of a day on a young planet known as a “super-Jupiter” in a distant solar system. Using NASA's James Webb Space Telescope, the study has uncovered new evidence that will help astronomers understand how the planet was formed. 

At the University of Virginia, a new initiative is reshaping how scientists think about the universe’s biggest mysteries.
The Interconnected Cosmos Initiative brings together researchers and students from across disciplines to create opportunities for discovery by breaking down academic barriers.
“The universe doesn’t respect disciplinary boundaries,” said Steven Majewski.
