The rosy pink buildings of a close-by galaxy glow brightly in a brand new picture from the Hubble House Telescope.
The Andromeda Galaxy — the Milky Manner’s closest galactic neighbor — is positioned about 2.5 million light-years away. Measuring roughly 152,000 light-years throughout, it has practically the identical mass as our Milky Manner galaxy. A current hubble picture, launched on Aug. 30, captures an in depth view of the northeast area of the famed galaxy, together with its intricately woven spiral arms and swathes of ionized gasoline that gas star formation.

“The mix of stellar nurseries and supernovas create a dynamic surroundings that excites the encircling hydrogen gasoline, flourishing it right into a backyard of star-studded roses,” NASA officers stated in a press release.
Utilizing Hubble’s Superior Digicam for Surveys and Broad Discipline Digicam 3, researchers had been in a position to peer by means of the clouds of gasoline and hone in on Andromeda’s spiral arms to research the galaxy’s huge assortment of stars.
“The extent of the examine spanned an enormous vary of stars, offering not only a clear view of Andromeda’s stellar historical past and variety, but in addition extra perception on stellar formation and evolution total,” NASA officers stated within the assertion.
“By inspecting these stars in our native cosmic neighborhood, scientists can higher perceive these inside galaxies within the distant universe.”
Andromeda is believed to be falling towards the Milky Manner on account of gravitational forces between the 2 galaxies and the invisible darkish matter that surrounds them each. Finally, the 2 galaxies are anticipated to expertise a head-on collision in about 2 billion to 4 billion years, which is able to drastically alter the construction of each Andromeda and the Milky Manner as we all know them right this moment. Nonetheless, some new analysis casts doubt on this collision concept — so, maybe solely time will inform.
