Astronomers have spotted another never-before-seen "nova" blaze to life in the night sky. This may be the first time that simultaneous stellar explosions have been visible to the naked eye in recorded ...

Less than two weeks later, on June 25, reports began to circulate of a second nova blossoming in the southern night sky, this time in the constellation Vela. This nova — later designated V572 Velorum ...

TWO new stars have suddenly appeared in the night sky, caused by some of the most powerful explosions in the universe. Two distant stellar explosions have burned so bright that we can now see them ...

The "new stars" are best seen from the Southern Hemisphere, but people have spotted them from the United States by looking ...

Classic novas typically appear in the night sky once a year at most, making the simultaneous appearance of two such events almost unheard of in astronomical circles. The first nova, designated V462 ...

This image shows the Vela pulsar wind nebula. Light blue represents X-ray polarization data from NASA’s Imaging X-ray Polarimetry Explorer. Pink and purple colors correspond to data from NASA ...

Located in the constellation Vela, the supernova remnant is the result of a stellar explosion that occurred about 11,000 years ago. The ESO view shows a small, but very intricate, ...

Located about 815 light-years from Earth in the constellation of Vela, this unique little nebula is commonly known as the Pencil Nebula. NGC 2736, as it is formally named, is a part of the Vela ...

The nebula is located about 4.5° west of the Vela pulsar and is moving through space at a speed of 400,000 mph (644,000 km/h). The eastern side of the Pencil Nebula is the brightest as it ...

This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago.

This one, CG4, is an especially dense patch of gas and dust within the larger Gum Nebula, which is home to the Vela Supernova Remnant and the Vela Pulsar. Once you see it, you can’t unsee it.
