Since humans first began looking to the sky, thousands of questions about space, the universe and galaxies have remained unanswered. The search for answers and deciphering the greatest mystery of the Universe Its creation allowed humans to discover the wonders of space, including galaxies, nebulae, moons, planets, and interacting black holes. Space agencies such as POT Keep sharing fascinating images from space so we can better understand the Universe.
The Carina Nebula is home to a million stars. The image was created with the help of information from NASA Hubble TelescopeNebulae are made of dust and gases that can stick together and form clumps under gravity. Over time, a clump becomes so large that it collapses under gravity, heating the material at its center.
The image from NASA’s Spitzer Space Telescope shows particles emitted by stars, called stellar winds, as well as light produced by stars, which can push surrounding material outward, creating the bubbles’ distinctive perimeter. The bubbles are estimated to be between 10 and 30 light-years across, based on what astronomers know about them and other cosmic bubbles.
NASA’s warm-color image captures the true essence of a pair of spiral galaxies. The image is the juxtaposition of two different images of the same spiral galaxy captured by NASA Webb and NASA’s Hubble Telescope.
The galaxy’s core is roughly centered and the arms appear to rotate counterclockwise. The structure resembles a cross section of a nautilus shell.
This image shows a medium-sized solar flare emitted by the Sun. The flare peaked on June 22, 2015. The image was captured by NASA’s Goddard Solar Dynamics Observatory, which constantly monitors the Sun.
The stellar image of the nova called GK Persei is a perfect example of a “classical nova,” which is an outburst of mass caused by a thermonuclear explosion on the dense surface of a white dwarf star. The image was provided by NASA’s Astronomer Observatory. Chandra X-ray ObservatoryThis usually occurs when a white dwarf and a larger star (often a red giant) orbit each other and together form a binary star system.
This arc-shaped nebula is located about 4,000 light-years from Earth. The nebula has formed from material blown away by the dying Sun-like star as it enters its white dwarf phase of evolution. Dense ridges of material are dragged back from the nebula’s central star, creating the arc shape.
