Latest Polar jet Stories
International team of researchers uses laser light and intense magnetic fields to simulate astrophysical jets in the lab.
An international team of astronomers has revealed a complicated outflow structure in the binary UY Aur (Aurigae).
Large stars can end their lives as violently cataclysmic supernovae. Small stars, in contrast, end up as planetary nebulae—colorful, glowing clouds of dust and gas. These nebulae were once thought to be mostly spherical.
Astronomers have long wondered exactly what the enigmatic jets given off by black holes are made of. Now, an international team of scientists, writing in the journal Nature, has apparently solved the mystery and discovered the composition of those high-speed beams of matter.
This particular object, located some 23,000 light-years away in the constellation Triangulum Australe, is in the early stages of its death cycle.
Astronomers say they have used the ALMA telescope to obtain a close-up view of material streaming away from a newborn star.
A supermassive black hole is believed to sit at the center of each large galaxy and a new technique designed to detect the dark abyss's spin could be the key to unraveling a galaxy's history.
Black holes are voracious monsters at the center of galaxies that shape the growth and death of the stars around them with their tremendous gravitational pull and explosive ejections of energy. Now, researchers are using them as a tool to probe the limits of spacetime.
A new study shows that high-speed jets launched from active black holes share fundamental similarities despite the mass, age or environment of their originating black hole.
NASA's Chandra X-ray Observatory has detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth, making it the most distant X-ray jet ever observed.
Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...
