When matter from the galaxies starts to accrete into super massive black holes, an enormous amount of energy is released across the whole electromagnetic spectrum (from radio emission up to X- and Îł- rays). This constitutes the characteristic signature of Read More …
Neutron stars are the ultra dense cores of massive stars that collapse and undergo a supernova explosion. This neutron star is located within the remains of a supernova — known as 1E 0102.2-7219 (E0102 for short) — in the Small Read More …
The galaxy NGC 3079, located about 67 million light years from Earth, contains two “super-bubbles”. A pair of balloon-like regions stretch out on opposite sides of the center of the galaxy: one is 4,900 light years across and the other Read More …
This galaxy resembles a bull’s eye, which is appropriate because its appearance is partly due to a smaller galaxy that passed through the middle of this object. The violent collision produced shock waves that swept through the galaxy and triggered large amounts Read More …
The Jellyfish Nebula (officially known as IC 443) is a supernova remnant about 5,000 light years from Earth. Astronomers have been looking for the spinning neutron star, or pulsar, from the explosion that created the remnant. New Chandra observations have Read More …
The central region of our galaxy, the Milky Way, contains an exotic collection of objects, including a supermassive black hole weighing about 4 million times the mass of the Sun (called Sagittarius A*), clouds of gas at temperatures of millions Read More …
