Andromeda milky way collision nasa. Led by astrophysicist Till Sawala of the University of Helsinki, a team of scientists has calculated that, in the next 10 billion years, the chance of a collision between the two galaxies is very close to 50 percent. While the Andromeda Galaxy contains about 1 trillion (10 12) stars and the Milky Way about 300 billion (3 × 10 11), the chance of even two stars colliding is negligible because of the huge distances For years, astronomers thought it was the Milky Way’s destiny to collide with its near neighbor the Andromeda galaxy a few billion years from now. This dramatic scenario, fueled by Andromeda’s This scientific visualization of a computer simulation depicts the joint evolution of the Milky Way and Andromeda galaxies over the next several billion years and features the inevitable massive collision. We spoke to one of the scientists to explain why. And . But a new simulation finds a 50% chance the For over a century, astronomers have believed that the Milky Way and Andromeda galaxies were destined to collide in a spectacular cosmic event. An example of a major interaction is a galactic collision, such as the one that astronomers estimate will happen in the future between the Milky Way and Did you know our home galaxy, the Milky Way, is on a collision course with the Andromeda Galaxy? 😱 In about 4–5 billion years, these two massive spiral galaxies will merge in a spectacular The Andromeda (M31) and Milky Way galaxies are on a potential collision course, with a merger expected in approximately 4–5 billion years, likely forming a new elliptical galaxy nicknamed From the impending collision between the Milky Way and Andromeda to the role of the Large Magellanic Cloud in diverting our galactic path, we provide a deep-dive into the data. 🌌 Milky Way & Andromeda: A Cosmic Collision in the Making 🚀 Our galaxy, the Milky Way, is on a collision course with the Andromeda Galaxy (M31)—a massive spiral galaxy over 2. The new research puts the chances at 50/50. 🌌 Milky Way-Andromeda Collision Course Confirmed Phillip Pitts and 2 others 󰍸 3 󰤦 Last viewed on: Feb 26, 2026 The collision between the Andromeda Galaxy and the Milky Way Galaxy, often referred to as a galactic merger, is a monumental cosmic event expected to occur in about 4. A study suggests the Andromeda-Milky Way collision might not happen after all. The Milky Way is part of the Local Group, which it dominates But such is the powerful gravitational pull of the Milky Way and Andromeda that they are being drawn toward each other and will one day crash. The Andromeda and Milky Way collision has already begun! in the future the they are expected to collide in about 4. 5 million light-years away. the milky way–andromeda collision The Milky Way and the Andromeda galaxy are on a slow but inevitable collision course, driven by gravity across intergalactic space. [12] Most galaxies are gravitationally organised into groups, clusters and superclusters. 5 billion years! The epic journey of the Andromeda Galaxy merging with our Milky Way The collision between the Andromeda Galaxy and the Milky Way Galaxy, often referred to as a galactic merger, is a monumental cosmic event expected to occur in about 4. A smashup between our own galaxy and Andromeda would trigger a firestorm New Hubble Space Telescope and Gaia data casts doubt on the certainty of a Milky Way collision with the Andromeda galaxy. Bottom line: Newly combined data from NASA and ESA sources shows the Andromeda and Milky Way galaxies might not collide as previously assumed. 5 billion years. A century later, astronomers using NASA’s Hubble Space Telescope were able to measure the sideways motion of Andromeda and found it was so negligible that an eventual head-on collision with the Milky Way seemed almost certain. There’s a black hole at the centre of the Milky Way.
