Dwarf galaxy Henize 2-10 continues to pack a punch, defying astronomers’ expectations.
Black holes are often described as the monsters of the universe: ripping apart stars, consuming anything that gets too close, and holding light captive. detailed evidence of
Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civil space program as well as aeronautics and aerospace research. Its vision is “Discover and expand knowledge for the benefit of humanity”.
The Hubble Space Telescope (often referred to as Hubble or HST) is one of NASA’s Great Observatories and was launched into low Earth orbit in 1990. It is one of the largest and most versatile space telescopes in use and features a mirror of 2.4 meters and four main instruments that observe in the ultraviolet, visible and near infrared regions of the electromagnetic spectrum. It is named after astronomer Edwin Hubble.
A black hole is a place in space where the pull of gravity is so strong that not even light can escape. Astronomers classify black holes into three categories based on their size: miniature, stellar, and supermassive black holes. Miniature black holes could have a mass smaller than our Sun and supermassive black holes could have a mass equivalent to billions of our Sun.
“>black hole in a new light: promoting, rather than suppressing, star formation. Hubble images and spectroscopy of the dwarf starburst galaxy Henize 2-10 clearly show an outflow of gas extending from the black hole to a bright star birth region like an umbilical cord, causing the cloud already dense form star clusters. Astronomers have previously debated that a dwarf galaxy could have a black hole analogous to the supermassive black holes in larger galaxies. Further study of dwarf galaxies, which have remained small throughout cosmic time, may shed light on the question of how the first seeds of supermassive black holes formed and evolved throughout the history of the universe.
