Nebulas exist in the space between stars, known as the Interstellar space. In fact, there is a Nebula close to Earth which could possibly be the remnant of the dying star, according to NASA.
It is called the Helix Nebula and is located approximately 700 light-years away from Earth. NASA captures the Nebulas with the help of its Spitzer Space Telescope, Hubble Space Telescope and the new James Webb Space Telescope.Lynds' Dark Nebula is a catalog of over 700 dark nebulae discovered by American astronomer Barbara Lynds in the 1960s.
Dark nebulae are clouds of dust and gas that block the light from stars and other objects behind them, making them appear dark in the night sky.
Therefore, they are also known as Absorption Nebulae.NASA's Astronomy Picture of the Day is an enchanting image of Lynds' Dark Nebula (LDN) 1622 which appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region.Read more on tech.hindustantimes.com
