Often known as M31, Andromeda is the Milky Means’s closest main galaxy, measuring roughly 152,000 gentle years throughout, with virtually the identical mass as our house galaxy.
As a spiral galaxy, Andromeda’s lengthy tendril-like winding arms are one in every of its most outstanding options, and at 2.5 million gentle years away from Earth, it’s essentially the most distant object that may be seen with the bare eye.
August and September are the perfect months to see it, because the galaxy is highest within the sky throughout these months.
Now, utilizing the Hubble Telescope, scientists have probed one in every of its tendrils within the northeast, revealing swathes of ionized fuel.
This picture exhibits the placement of Hubble’s view throughout the Andromeda galaxy (Picture credit score: NASA, ESA, M. Boyer (Area Telescope Science Institute), J. Dalcanton (College of Washington), and KPNO/NOIRLab/NSF/AURA/Adam Block; Picture Processing: Gladys Kober (NASA/Catholic College of America)

“These areas — that are frequent in spiral and irregular galaxies — typically point out the presence of current star formation. The mixture of stellar nurseries and supernovae create a dynamic atmosphere that excites the encompassing hydrogen fuel, flourishing it right into a backyard of star-studded roses.”
The gorgeous crimson bouquets have been seen in such stunning readability as a result of Hubble’s Superior Digicam for Surveys (ACS) and Wild Subject Digicam 3 (WFC3), permitting scientists to research the gathering of stars buried throughout the cosmic bunches.
With ACS and WFC3’s vast spectral protection, Hubble is ready to peer by way of the hedges of fuel and try an enormous pattern of stars, offering not only a clear view of Andromeda’s stellar historical past and variety.
The photographs all supply a deeper perception into stellar formation and evolution, and NASA provides:
“By analyzing these stars in our native cosmic neighborhood, scientists can higher perceive these inside galaxies within the distant universe.”
We have additionally acquired all the knowledge you want about what to the what what there’s to see within the sky this month in our information to astrophotography in September 2024
