This discovery could help NASA and other organizations protect astronauts, satellites, and technologies on the ground from the potentially harmful effects of space weather.
Hypernova shockwave eruptions: Hypernovae are even more violent astronomical phenomena than supernovae, with explosion energies that exceed those of supernovae by more than ten times. These powerful explosions are usually accompanied by powerful jets that create unique shock explosion structures at the poles of the star. The jets not only cause the explosion, but also create strong flow instabilities within the ejected material, which causes further mixing of the star's interior. Recent observational data suggest that the famous supernova 1987A may be associated with a jet explosion, rather than the spherical explosion predicted by previous one-dimensional models.

This image from the ALMA telescope shows the star system HD101584 and the complex gas clouds surrounding the binary pair. The clouds are the result of two stars that shared a common outer layer in the last moments of their lives. Credit: ALMA (ESO/NAOJ/NRAO), Olofsson et al., : Robert Cumming.

Dead and Alive: Astronomers Reveal Star Pairs That Are Changing Our Universe

Mapping giant radio galaxies: new insights into the largest cosmic structures

This figure shows a stage in the merger of two galaxies that creates a single galaxy with two supermassive black holes at the center and surrounded by disks of hot gas. The black holes orbit each other for hundreds of millions of years as they merge to form a single supermassive black hole that sends out powerful gravitational waves. Credit: NASA/CXC/A.Hobart
