We conducted the stellar photometry using the archive images of the Hubble Space Telescope of the dwarf irregular galaxy Cas 1 located near the Milky Way. Blue supergiants detected in the obtained Hertzsprung-Russell diagram are concentrated in star-forming regions. We found that the red star ...
Astronomers can provide detailed images of beautifullyswirling galaxies millions of miles away. It's our own galaxy they haven't beenable to get their arms around. "It's clear that the Milky Way has a structure like those,but it's hard to tell being in it," said Mark Reid of the Harv...

They allow astronomers to understand the structure of the Universe; for example, to see the organization of the Solar System and to recognize that galaxies lie beyond the Milky Way. The derived physical sizes of bodies scale with the distances adopted for them, whereas their energetics scale ...
Concerning the Distance to the Center of the Milky Way and its Structure The distance to the Galactic center inferred from OGLE RR Lyrae variables observed in the direction of the bulge is Ro=8.1+-0.6 kpc. An accurate determinat... DJ Majaess - Acta Astronomica -Warsaw and Cracow- 被引...
TheCanis Major Dwarf Galaxyis also known as theCanis Major Overdensity. The galaxy is known as adwarf galaxyon account of its size. The galaxy gets its name as it is located in theCanis Majorconstellation. Interesting Fun Facts It is the nearest galaxy to our ownThe Milky WayGalaxy. ...
(LAMOST) have collected spectra of millions stars in the Milky Way.Utilizing this huge sample of stars to study the assembling history and structure of our Galaxy requires accurate estimates of distance,extinction,age,and mass for individual stars.Combining the parallax constraint from Gaia EDR3 ...
Based on archival Hubble Space Telescope images, we have performed stellar photometry for a region of the spiral galaxy IC 342 located in the Milky Way zone. On the constructed Hertzsprung-Russell diagram, we have identified the red giant branch and determined the distance modulus for the galaxy...
Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. It is one of the few visible to the unaided eye, appearing as a milky blur. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its di
prone to enormoussolar flares. These flares, which occur multiple times daily, can be strong enough to make Proxima Centauri visible to thehuman eye. In 2019 Proxima Centauri unleashed the largest solar flare ever recorded in theMilky Way Galaxy, shining 14,000 times brighter than average inultr...
