With the chemical rockets in use today, weвЂ™d need a fuel tank larger than the entire observable universe to achieve interstellar flight. The need to carry fuel stunts our ability to explore. The ionized hydrogen is positively charged after losing electrons. This is an area of ionized hydrogen caused by the starвЂ™s ultraviolet radiation. But while still active, B and O-type stars such as Lacerta 10 are often surrounded by a Stromgren sphere. Though Lacerta 10 is young and in its main sequence, after just a few million years its collapse will erupt in a supernova rich with elements, a fertile ground for the formation of stunning new nebula.

ItвЂ™s a blistering and exhausting spectacle the star transcends the usual warm citrus colors of stellar bodies - orange, red, embers of yellow - and is instead an almost glacial blue despite its impressive heat. Lacerta 10 has a surface temperature almost 6 times hotter than the sun. Here, in the Lacerta constellation, lies one such star. A mere 0.00007 percent of our universeвЂ™s stars are luminous enough to be classified as an O-type. These O-type and B-type stars are the hottest and brightest of all the spectral classes. Lacerta contains some of the universeвЂ™s rarest objects. Yet just to the right of it is a lesser-known treasure trove. We are often drawn in by the Andromeda GalaxyвЂ™s flowerbed of stars situated in its dusty, feathered rings. It shares borders with the constellation of Andromeda, home to the Milky WayвЂ™s bright and fascinating galactic neighbor.
