This creates an object known as a magnetar. Starquakes on the surface of a magnetar — the equivalent of crustal movements on Earth that generate earthquakes — can release tremendous amounts of energy. In one-tenth of a second, a magnetar might produce more energy than the sun has ...
The life of a star, no matter its size, is a balancing act between the inward "push" of gravity and the outward push provided by photons generated as they conductnuclear fusion, the forging of heavy atomic nuclei from light nuclei, at their cores. When stars run out of hydrogen to fuse...
The first planet to be discovered inside the habitable zone of a Sun-like star. Its... Cosmos What If a Magnetar Collided With a Black Hole? In the center of our galaxy, the Milky Way, there is a supermassive black hole feeding on nearby stars. It’s called Sagittarius A*. And if ...
G1.9+0.3 is another galactic far-side object found in observations by the Very Large Array, a series of radio telescopes located in the New Mexico desert. It’s a supernova remnant, the expanding gaseous debris from a star that exploded. The light from this explosion reached Earth only a ...
What would happen if you took the most energetic light source in the Universe and smashed it into a massive gravitational monster? Well, you might reverse the flow of... Cosmos What If a Magnetar Collided With a Black Hole? In the center of our galaxy, the Milky Way, there is a superm...
Stars are primarily made up of hydrogen and helium gas. Fusion occurs in the core, forming helium from hydrogen. This process of fusion is what powers the star, as it releases heat and light.Answer and Explanation: When a star exhausts its core hydrogen supply, it can no longer perfo...
What is cosmology in philosophy? How do cosmic rays affect Earth? What would happen if a magnetar came close to Earth? What is the cosmological principle? What is caused by light refraction in the atmosphere? What is the elasticity in the expanding universe theory?
they collide and merge. These collisions could also trigger cosmic explosions called Type Ia supernovas, which could be discovered if there is an association between thesesupernovasand FRBs. It is also possible that thecollision of white dwarfswith neutron stars creates a magnetar, leading to F...
What is it? There are lots of different types of variable stars and objects in the sky. They emit variable light all across the spectrum. Could it be a low-mass star or a substellar object? Could it be apulsaror a transient magnetar? According to the authors, none of those possibili...
The GRB from a dying star is caused when the newly born black hole begins to feed on surrounding matter that was once the outer layers of the progenitor star. Powerful magnetic fields channel electrically charged material to the poles of the new black hole, where it is blasted out as two ...
