Galactic Cannibalism May Explain Newly Detected Dark Matter Halo
Astrophysicists say that an extended halo of dark matter may surround Tucana II, one of the many dwarf galaxies neighboring the Milky Way. The ancient galaxy may also have been the site of one of the universe’s earliest galactic collisions.

Scientists: Center of Milky Way Exploded Not Long Ago
Just 3.5 million years ago, after the dinosaurs had already become extinct and ancient human ancestors began to walk the Earth, the center of the Milky Way galaxy lit up as an epic beam of energy burst forth, creating a flare that expanded to more than 200,000 light years away from the supermassive black hole that created it.

As Seen From Hubble: the Hockey Stick Galaxy
The Hubble Telescope captured this image of galaxy NGC 4656, also known as “The Hockey Stick Galaxy.” Located in the constellation Canes Venatici (the Hunting Dogs), the galaxy is shaped like an elongated warped stick stretching through space before curling at one end to give it its common name.
