supernova

A stellar flash like this has never been seen before -- supernovas and novas expel matter out into space.

It takes lots of power to set the projection to on its orbit around the supernovas, burning up a sun just to say goodbye.

The most massive of these young stars have already sped through their evolution in a few million years and exploded as supernovas.

Her eyes shine softly with a silvery light but can also burst in a blinding flash like supernovas.

The most massive of these young stars race through their evolution in a few million years and explode as supernovas .

To do this, scientists used special tricks to determine the distances of many exploded stars, called supernovas, throughout the universe.

Supernovas can be very bright for a short time and usually release huge amounts of energy.

The energy input from the supernovas could also be driving gas out of the central region.

Dark energy causes the acceleration by pushing space itself apart, altering the distances to the supernovas as it does so.

Explanation: One of the brightest supernovas in recent years has just been recorded in the nearby Whirlpool galaxy (M51).

Many of these newly formed stars are very massive and race through their evolution to explode as supernovas .

Explanation: One of the nearer supernovas of recent years was discovered last month in the bright nearby galaxy M100.

Most supernovas spotted at the Palomar Observatory are around 1 billion light-years away, far too distant to be seen by amateurs.

Recent images by the Chandra X-ray Observatory have shown that X-ray light surrounding the ring is likely emission from recent supernovas .

Pulsars and supernovas seem to take over at about 9: 00 and are truly spectacular.

Hubble's observations of supernovas helped reveal that the mysterious energy is a constant presence in the universe.

Supernovas are a class of violently exploding stars that become super bright after eruption.

Chandra's improved sensitivity is making possible more detailed studies of black holes, supernovas, and dark matter.

Historically, only seven supernovas were known to have been recorded before the 17th century.

A collection of Hubble Space Telescope images shows distant supernovas, the death explosions of massive stars.

Weird Worlds is also full of random events, from supernovas to secret quests beyond the initial mission parameters.

Long GRBs are therefore different than many types of supernovas , which occur more uniformly distributed in their host galaxies.

Supernovas can briefly shine as brightly as an entire galaxy.

They are sometimes associated with supernovas ? another explosive way stars die ? but are separate events.

If supernovas occurred randomly throughout the Milky Way, Earth could expect one every 5 billion years.

Maybe supernovas were different in the past, for example, which made it look like the universe was accelerating.

Teacher: Can you tell us some more about white dwarfs and supernovas?

Mr. PAUL GRAY: There are friends of mine who have searched for supernovas, and they have searched close to 2, 000, 3, 000 hours.

Stars of this mass aren't heavy enough to end their lives in the spectacular explosions known as supernovas ;

Burning supernovas of all sound and sight
