In an article I wrote yesterday about the supermassive black hole at the core of the Milky Way, I presented a theory suggesting that the X-ray flares produced by Sagittarius A* are caused by asteroids falling through the event horizon. Here are more details of that study. Now, the image in this post is a rendition t... |

According to the results of new observations conducted with the NASA Chandra X-ray Observatory, it would appear that the supermassive black hole at the core of the Milky Way – called Sagittarius A* – is growing by nibbling on asteroids that stray too close to its surface.
The data indicate that the spa... |

A while back, we reported on the chance that cosmic fireworks may soon drench the core of the Milky Way. A gas cloud was observed heading for the supermassive black hole in the center of the galaxy, and its collision with the dark behemoth was bound to cause a firework show of sorts. Now, astronomers determined the o... |

One of the things that has been puzzling astrophysicists concerning Sagittarius A* – the massive black hole at the center of the Milky Way – is its seeming lack of activity, when compared to similar objects in other galaxies. Now, experts are analyzing what would happen if the black hole were to wake up.

The fact that life exists in the Milky Way is plain as day. Now the thorniest issue is establishing how to find it. Astronomers say that limiting our search for our origins to this planet, the solar system or whatever exoplanets we can see exclusively would be a mistake.

According to the results of a new scientific study, it would appear that the Milky Way's spiral shape was not a direct product of its evolutionary path, but rather a result of collisions between our galaxy and two other dwarf galaxies. The events took place within the last 2 billion years.
