Cosmic 'dust' from supernovae hints at how stars are born

New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject ...

Volcanic activity may be the cause of marsquakes

Volcanic activity beneath the surface of Mars could be responsible for triggering repetitive Marsquakes, which are similar to earthquakes, in a specific region of the Red Planet, researchers from The Australian National University ...

Studying the edge of the sun's magnetic bubble

Our corner of the universe, the solar system, is nestled inside the Milky Way galaxy, home to more than 100 billion stars. The solar system is encased in a bubble called the heliosphere, which separates us from the vast galaxy ...

Cosmic rays may be key to understanding galactic dynamics

Cosmic rays are charged subnuclear particles that move close to the speed of light, constantly raining down on the Earth. These particles are relativistic, as defined by Albert Einstein's special relativity, and manage to ...

The mystery of heavy elements in galactic cosmic rays

Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving ...

Probing deeper into origins of cosmic rays

Cosmic rays are high-energy atomic particles continually bombarding Earth's surface at nearly the speed of light. Our planet's magnetic field shields the surface from most of the radiation generated by these particles. Still, ...

Stellar eggs near galactic center hatching into baby stars

Astronomers found a number of baby stars hiding around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous studies had suggested that the environment there is too harsh to form ...
