We do not see many changes in the sky from night to night. Over the course of a human lifespan, only the planets, the moon, and an occasional comet are likely to move and change appearance significantly. But sometimes the sky changes in a flash. Sometimes, stars die a violent death called a supernova. A supernova occurs when a very large star exhausts its nuclear fuel.

How to See a Star Explode in

All rights reserved. Five or so years from now, you may be able to witness a new "star" appearing in the night sky, a cosmic gem that should glitter in the northern wing of the constellation Cygnus , the swan, for a good portion of a year. For the first time, astronomers are confidently predicting that a specific stellar system will explode within a defined period of time, becoming more than 10, times brighter than it is now. The explosion will be visible from Earth with the naked eye, and it could be about as bright as Polaris, the north star. The eruption will signal the moment two stars locked in a cosmic dance have merged, exploding into a red nova that will briefly give Cygnus an extra stellar spangle. Its debut should happen within a short enough interval that parents teaching their kids about the stellar tapestry overhead can reliably point to the spot where a new pinprick of light will appear.

Nova Star Explosion Is Visible to the Naked Eye: Where to Look

The known history of supernova observation goes back to AD, when supernova SN appeared; which is the oldest appearance of a supernova recorded by humankind. Since then, several additional supernovae within the Milky Way galaxy have been recorded since that time, with SN being the most recent supernova to be observed in this galaxy. Since the development of the telescope , the field of supernova discovery has expanded to other galaxies.

A dazzling star explosion discovered in the night sky last week is the brightest nova seen from Earth in at least five years and it's visible now to the naked eye. The Nova Delphinus star explosion can be seen by the naked eye from places without too much light pollution, skywatching experts say. The stellar phenomenon is expected to be visible for weeks to come, and its location in the night sky should make the nova easy for even novice stargazers to spot.
