![]() This would easily be the biggest feature on the nighttime sky. If its gaseous halo could be viewed with the naked eye, it would be about three times the width of the Big Dipper. At a distance of 2.5 million light-years, it is so close to us that the galaxy appears as a cigar-shaped smudge of light high in the autumn sky. ![]() The Andromeda galaxy, also known as M31, is a majestic spiral of perhaps as many as 1 trillion stars and comparable in size to our Milky Way. The halo is then contaminated with this material from stellar explosions. Heavier elements are cooked up in the interiors of stars and then ejected into space-sometimes violently as a star dies. This difference is a likely result from the impact of supernova activity in the galaxy’s disk more directly affecting the inner halo.”Ī signature of this activity is the team’s discovery of a large amount of heavy elements in the gaseous halo of Andromeda. “We find the inner shell that extends to about a half million light-years is far more complex and dynamic,” explained study leader Nicolas Lehner of the University of Notre Dame in Indiana. It’s full of clues regarding the past and future evolution of the galaxy, and we’re finally able to study it in great detail in our closest galactic neighbor.” “This reservoir of gas contains fuel for future star formation within the galaxy, as well as outflows from events such as supernovae. “Understanding the huge halos of gas surrounding galaxies is immensely important,” explained co-investigator Samantha Berek of Yale University in New Haven, Connecticut. This is the most comprehensive study of a halo surrounding a galaxy. They also found that the halo has a layered structure, with two main nested and distinct shells of gas. This means that Andromeda’s halo is already bumping into the halo of our own galaxy. Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the galaxy-about halfway to our Milky Way-and as far as 2 million light-years in some directions. In a landmark study, scientists using NASA’s Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large galactic neighbor. Four Successful Women Behind the Hubble Space Telescope's Achievements.Characterizing Planets Around Other Stars.Measuring the Universe's Expansion Rate.I have a feeling 8 years from now we'll be talking about Oct 4, 2016. We announced the 1st version of Android 8 years ago today. Out of the many rumor waves and product theories, a tweet made by Google’s Android head Hiroshi Lockheimer says it all. It is expected to have a 7-inch display and 4GB RAM. A little piece of information is available about the supposed Nexus device hardware. 9to5Google has claimed (no 100% confirmation) that a Huawei Nexus tablet will be launched running the Andromeda OS. ![]() It has been assumed that Nexus line of smartphones would die after Google’s October 4 event. “What is dead may never die”, Andromeda running on a Huawei Nexus The Pixel 3 running Andromeda is expected to launch in Q3 2017. This would be supplemented by a bunch of sensors, backlit keyboard, stereo speakers, quad mics, two USB-C ports, stylus support, 10 hours of battery life, and a 3.5mm jack. Under the hood, it would have an Intel Core M or i5 processor along with 8/16GB memory and 32/128GB storage space. ![]()
