This image was captured by the Mastcam-Z imager aboard NASA's Perseverance Mars rover on the following sol, April 8, 2021. NASA's Ingenuity helicopter unlocked its blades, allowing them to spin freely, on April 7, 2021, the 47th Martian day, or sol, of the mission. What remains is a dense neutron star with a little more mass than our sun.Ī study based on the new research published Monday in the journal Nature Astronomy. This sudden drop in electron pressure triggers a collapse and the star buckles beneath its own weight. As the star’s core loses fuel, gravitational forces push the core’s electrons and fuse them with atomic nuclei. This third, previously unobserved type is referred to as an electron capture supernova – and it was orginally described by Nomoto in 1980.
The other type is called a thermonuclear supernova, and it occurs when a low-mass star remnant called a white dwarf – usually less than eight times the mass of our sun – explodes after pulling matter from a companion star into itself.īut what happens to star between eight and 10 solar masses, such as the star involved in supernova 2018zd? They explode a little differently. During a core-collapse supernova, a massive star (more than 10 times the mass of our sun) exhausts its fuel and the star’s core caves in to a black hole or a dense remnant called a neutron star. Typically, supernovae occur in two flavors. The main support that prevents stars from collapsing beneath the weight of their own gravity is the energy in their core.
