When was the Vela supernova?

12,300 years ago
The Vela supernova remnant is a supernova remnant in the southern constellation Vela. Its source Type II supernova exploded approximately 11,000–12,300 years ago (and was about 800 light-years away).

Is the Milky Way a supernova remnant?

Supernovas are stellar explosions that seed the galaxy with elements vital for life. This supernova remnant is the first known example in our own Milky Way galaxy of an unusual type of white dwarf stellar explosion called a Type Iax supernova, according to a statement from the Chandra X-ray Observatory.

What is one of the best known supernova remnants?

A supernova remnant (SNR) is the remains of a supernova explosion. SNRs are extremely important for understanding our galaxy. They heat up the interstellar medium, distribute heavy elements throughout the galaxy, and accelerate cosmic rays….Supernova Remnants.

How old is the Vela Supernova Remnant?

This site provides some background about the Vela supernova remnant (SNR), a roughly 11,000 year old leftover from a supernova explosion in our Milky Way galaxy. This object is about 250 parsec (815 light years) away in the constellation of Vela (which represents the sail of the mythical Argonaut’s ship).

Where are the filaments of the constellation Vela located?

At the northwestern edge of the constellation Vela (the Sails) the 16 degree wide, 30 frame mosaic is centered on the glowing filaments of the Vela Supernova Remnant, the expanding debris cloud from the death explosion of a massive star. Light from the supernova explosion that created the Vela remnant reached Earth about 11,000 years ago.

Is the Vela remnant part of the Gum Nebula?

Some 800 light-years distant, the Vela remnant is likely embeddedin a larger and older supernova remnant, the Gum Nebula. The broad mosaic includes other identifiedemission and reflection nebulae, star clusters, and the remarkable Pencil Nebula. Tomorrow’s picture: Hotel California

Which is the closest supernova remnant to Earth?

Vela Supernova Remnant. The Vela supernova remnant (SNR) is one of the closest known to us. The Geminga pulsar is closer (and also resulted from a supernova), and in 1998 another near-Earth supernova remnant was discovered, RX J0852.0-4622, which from our point of view appears to be contained in the southeastern part of the Vela remnant.
