I note that as seen from Earth, The Andromeda and Triangulum galaxies are more than 90 degrees from the galactic center, while the Large and Small Magellanic Clouds are on the other side of the Galactic center and about 60 degrees from the galactic center. So if you can remember that, it...

v variations (Gontcharov 2012) has allowed us to produce a 3D interstellar extinction map within the nearest kiloparsec from the Sun with a spatial resolution of 50 pc and an accuracy of {ie87-1}. Thismap is compared with the 2D reddening map by Schlegel et al. (1998), the 3D extin...
The Milky Way, at the centre, is part of the Local Group of galaxies, with the Virgo cluster our nearest neighbour. Majestic spiral The Milky Way’s spiral structure is dominated by two main arms called Scutum-Centaurus and Perseus. It also features a dens...
around the nearest Star, and not the converse. We then learned that the Sun formed part of an immense galaxy, the Milky Way, itself spinning in a vast cosmological dance. More recently, we learned that the Milky Way formed part of a larger cluster of galaxies, known as the Local Group....

“By contrast, our approach is able to probe the nearest few hundred supermassive black holes that are actively consuming matter – and this number will increase significantly with the launch of ESA’s Athena satellite.” Characterizing the environments closely surrounding black holes is a core scien...
After proceeding as above - get the projected map position in pixelspace (pt) and draw the snr symbol - we use the quadtree.find() function to find the nearest neighbor relative to this position, and if it is more distant than our limit above, add it to quadtree and draw the label, ...
For 30 years, astronomers have been trying to identify why the motions of the Milky Way, our nearest large galaxy neighbor Andromeda, and their smaller neighbors deviate from the overall expansion of the Universe by over 600 km/s (1.3 million mph). The new study shows that roughly half of...
Astronomical map, any cartographic representation of the stars, galaxies, or surfaces of the planets and the Moon. Modern maps of this kind are based on a coordinate system analogous to geographic latitude and longitude. Most modern maps are compiled fro
