Since humans began looking up into the sky for the first time, thousands of questions about space, the universe, and galaxies have remained unanswered. The quest to search for answers and decode the biggest mystery of the Universe about its creation introduced humans to wonders of space, including interacting galaxies, nebulas, moons, planets, and black holes. Space agencies like NASA keep sharing mesmerising images from space for us to understand the Universe better.
The Carina Nebula is home to a million of stars. The image has been formed with the help of information from NASA Hubble telescope. Nebulas are made of dust and gases, which can get pulled together into clumps by gravity. Eventually, a clump will get so big that it collapses from gravity, heating the material at its centre.
The image from NASA's Spitzer Space Telescope, showcases particles emitted by the stars, called stellar winds, as well as a the light stars produce, can push the surrounding material outward, creating the distinct perimeter of the bubbles. The bubbles are estimated to be 10 to 30 light-years across, based on what astronomers know about them and other cosmic bubbles.
The warm-coloured NASA image captures the true essence of a spiral galaxy pair. The image is the juxtaposition of two different images of same spiral galaxy captured by NASA Webb and NASA Hubble telescope.
The galaxy’s core is roughly centered and the arms appear to rotate counterclockwise. The structure looks like a cross section of a nautilus shell.
The image provides a glimpse of a medium-sized solar flare, emitted by the Sun. The solar flare peaked on June 22, 2015. The image was captured by NASA Goddard's Solar Dynamics Observatory whichwatches the Sun constantly.
The stellar image of nova called GK Persei is a perfect example of “classical nova” which is an outburst of mass caused by a thermonuclear explosion on the dense surface of a white dwarf star. The image has been provided by NASA's Chandra X ray observatory. This often happens when a white dwarf and a larger star – often a red giant – orbit each other. Together, they become a binary star system.
This bow-shaped nebula is located around 4,000 light-years from Earth. The nebula has been formed from the material casted off from the dying Sun-like star as it enters its white-dwarf phase of evolution. Dense ridges of material are swept back from the nebula’s central star creating the bow shape.
