Hello guys, We're here with some new information from NASA :
As the holiday season approaches, people in the northern hemisphere will gather indoors to stay warm. In keeping with the season, astronomers have studied two groups of galaxies that are rushing together and producing their own warmth.

Astronomy news update from NASA :
What do neutron stars look like? Previously these city-sized stars were too small and too far away to resolve. Recently, however, the first maps of the locations and sizes of hotspots on a neutron star's surface have been made by carefully modeling how the rapid spin makes the star's X-ray brightness rise and fall. Based on a leading model, an illustrative map of pulsar J0030+0451's hotspots is pictured, with the rest of the star's surface filled in with a false patchy blue. J0030 spins once every 0.0049 seconds and is located about 1000 light years away. The map was computed from data taken by NASA's Neutron star Interior Composition ExploreR (NICER) X-ray telescope attached to the International Space Station. The computed locations of these hotspots is surprising and not well understood. Because the gravitational lensing effect of neutron stars is so strong, J0300 displays more than half of its surface toward the Earth. Studying the appearance of pulsars like J0030 allows accurate estimates of the neutron star's mass, radius, and the internal physics that keeps the star from imploding into a black hole.

Our new 'Word Of The Day' article update : primum mobile , n :
(astronomy, historical) The outermost celestial sphere of the heavens in Ptolemaic astronomy, which was believed to cause all the inner spheres to rotate. (chiefly philosophy, theology) The prime mover or first cause (“an initial cause from which all other causes and effects follow”). (by extension) The person or thing that is the main impetus for some action; a driving force. Today is UN Arabic Language Day, one of six such days established by UNESCO to celebrate multilingualism and cultural diversity and to promote the equal use of its working languages. The term primum mobile is a calque of Arabic مُحَرِّك أَوَّل‎ (muḥarrik ʾawwal, literally “first mover”).
