Other globular clusters that orbit the center of our Milky Way as a satellite – i.e. Hopkins Observatory in Arizona (for the Northern Hemisphere) and the Cerro Tololo Inter-American Observatory in Chile (for the southern hemisphere). The prevalence of M-class stars is what made the formation easy to detect. And here is a video by the same author on the subject. And maybe even that of the five year old…. This stellar formation is about 42,000 light years from the galactic center, and a mere 25,000 light years from our Solar System.

The Andromeda Galaxy (M31) is the closest spiral galaxy to us, and though it’s gravitationally bound to the Milky Way, it’s not the closest galaxy by far – being 2 million light years away. At 70,000 light years from Earth, this galaxy was determined in 1994 to be closer to us than the Large Magellanic Cloud (LMC), the irregular dwarf galaxy that is located 180,000 light years from Earth, and which previously held the title of the closest galaxy to the Milky Way. But we do know that our Milky Way has a spiral nature from observations made from within our Galaxy (though whether or not it is a barred spiral is still being debated). the Canis Major Overdensity.

Figures listed are composites of many measurements, some of which may have had their individual error bars tightened to the point of no longer overlapping with each other. From this data, astronomers were able to conduct a survey of 70% of the sky, detecting about 5,700 celestial sources of infrared radiation. Because of this technique, the astronomers were able to detect a very significant over-density of class M giant stars in a part of the sky occupied by the Canis Major constellation, along with several other related structures composed of this type of star, two of which form broad, faint arcs (as seen in the image close to the top). 00:26:08 How can the methuselah star be older than the Universe?

Infrared astronomy takes advantage of advances in astronomy that see more of the Universe, since infrared light is not blocked by gas and dust to the same extent as visible light. In this week's live questions show, I explain how amateurs can contribute to space and astronomy research, will I sign up for Starlink, and what would happen if the supermassive black hole at the heart of the Milky Way turned into a quasar? For many years astronomers thought the Large Magellan Cloud (LMC) was closest, but its title was supplanted in 1994 by the Sagittarius dwarf galaxy. Hello and welcome to What Da Math!
