Milky way galaxy collided with antlia galaxy 2: ok techno

JAKARTA- Collision between galaxies seems to be a hot talk in the world of astronomy. Even astronomers predicted a collision between the Milky Way and the Andromeda galaxy.

These are two large galaxies, so it is feared to have a major impact on Earth. But this is not yet known scientifically.

Interestingly, recently researchers discovered that the Milky Way had collided with a kerdi galaxy dubbed Antlia 2.

Reporting from the page Technology Extreme, Thursday (06/20/2019) scientists discovered Antlia 2 in late 2018 in the orbit of the Milky Way. The discovery was an unusual object because of its very low density.

Although it is the same size as the Large Magellan Cloud satellite galaxy, it is about 10,000 times more scattered. According to a team from the Rochester Institute of Technology, Antlia's current state and confusing ripples in the Milky Way's hydrogen gas disks can be explained by a collision between the two galaxies. Of course, Antlia 2 has a much worse impact than the Milky Way.

Using data collected by the European Space Agency's (ESA) satellite Gaia, researcher Sukanya Chakrabarti and his team calculated the past trajectory of Antlia 2. Based on the model produced by the team, Antlia 2 can collide with the Milky Way several hundred million years ago.

Many of you may consider galaxies as solid objects and unite from star to wall. However, most galaxies are empty spaces. When they "collide," there can not be two stars to be known.

Instead, gravitational interactions can cast stars into space or cause them to migrate from one galaxy to another. Dust and gas clouds can also join, causing an increase in star formation.

Thus, the Milky Way is still basically the same as before entering Antlia 2. However, smaller galaxies are destroyed by the gravity of their larger neighbors.
