The Milky Way’s Most Recent Supernova
G1.9+0.3 is the remnant of the most recent supernova in our galaxy. It is estimated to have occurred about 110 years ago in a dusty region of the galaxy that blocked visible light from reaching Earth, but it can be seen by x-ray telescopes such as Chandra X-ray Observatory.

Henize 2-10
Henize 2-10 is a dwarf galaxy, and it is the first dwarf galaxy ever discovered to contain a supermassive black hole at its center. This was surprising because the black hole is about one quarter of the size of the one at the center of the Milky Way Galaxy. However, Henize 2-10 is only about1/1,000th the size of the Milky Way..

The Galactic Center
This visualization takes the viewer to the center of our Galaxy, the position of the Milky Way’s supermassive black hole (Sgr A*). Supercomputer simulations using data from the Chandra X-ray Observatory show the effects of dozens of massive stars with fierce winds blowing off their surfaces in the region surrounding Sgr A*. Blue and cyan represent X-ray emission from ultra-hot gas with temperatures of tens of millions of degrees. Red shows ultraviolet emission from moderately dense regions of cooler gas with temperatures of merely tens of thousands of degrees, and yellow shows cooler gas with the highest densities and lowest temperatures. Use the widget in the upper left corner to pan and tilt around the simulation.

The Crab Nebula
In 1054, observers around the world reported the appearance of a “new star” in the direction of the constellation Taurus. The remnant of that supernova is called the Crab Nebula, and it is powered by a quickly spinning, highly magnetized neutron star called a pulsar. The pulsar was formed when the massive star ran out of its nuclear fuel and collapsed. The combination of rapid rotation and a strong magnetic field in the Crab generates an intense electromagnetic field that creates jets of matter and anti-matter moving away from both the north and south poles of the pulsar and an intense wind flowing out in the equatorial direction.
This composite image of the nebula was created with data from the Chandra X-ray Observatory (blue and white), the Hubble Space Telescope (purple), and the Spitzer Space Telescope (pink).
