What are the most conspicuous features dark areas on the surface of the Sun?
The most conspicuous features on the Sun are aptly called sunspots. These dark splotches belong to the photosphere and occasionally grow large enough to be visible to the naked eye from Earth.
What do streams of protons and electrons emitted from the Sun produce?
The very highest energy radiation given off by the Sun is not due to a hot gas but is actually produced by erupting streams of very-high speed electrons and protons which strike the ordinary atoms of the Sun's atmosphere with sufficient force to generate X-rays and gamma rays.
What is the main factor that determines what will happen to a star after it consumes all of its nuclear fuel?
About 75% of the mass of the star is ejected into space in the supernova. The fate of the left-over core depends on its mass. If the left-over core is about 1.4 to 5 times the mass of our Sun, it will collapse into a neutron star. If the core is larger, it will collapse into a black hole.
What is an exploding star called?
A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
Do supernovae explode?
These stars end their evolutions in massive cosmic explosions known as supernovae. When supernovae explode, they jettison matter into space at some 9,000 to 25,000 miles (15,000 to 40,000 kilometers) per second.
Where do sunspots occur on the Sun?
Their positions follow a pattern during the solar cycle. Surprisingly, almost all sunspots are found in two bands on the Sun, just north and south of the equator. At the start of the cycle, the sunspots appear at latitudes of about 30 degrees, both north and south of the equator.
Which part of the Sun’s atmosphere is the hottest?
Heat is created in the very center of the sun, at its core, where the temperature is a blistering 27 million degrees Celsius. And just like walking away from a campfire, the temperature gets cooler further away from the core.
Is the Sun a constant explosion?
Don't be alarmed, but the sun is constantly exploding.
What phenomenon occurs on Earth as a result of solar flares on the Sun?
What phenomenon occurs on Earth as a result of solar flares on the Sun? Northern lights.
Which main sequence stars are the most massive?
Although R136a1 is the most massive known star, it is not the largest, since it only stretches about 30 times the radius of our sun. The largest known star is UY Scuti, a hypergiant with a radius somewhere around 1,700 times larger than the sun. Its mass, however, is only 30 times that of our nearest star.
What will happen when the Sun turns into a red giant?
In approximately five billion years, our own sun will transition to the red giant phase. When it expands, its outer layers will consume Mercury and Venus and also reach Earth. Scientists are still debating whether or not our planet will be engulfed, or whether it will orbit dangerously close to the red giant sun.
Is the sun an exploding star?
No supernova, no black hole Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either.
Will the Sun explode?
No supernova, no black hole Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either. In order to create a supernova, a star needs about 10 times the mass of our sun.
What are sunspots and solar flares?
Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun's surface. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots.
Where are most sunspots found?
Surprisingly, almost all sunspots are found in two bands on the Sun, just north and south of the equator. At the start of the cycle, the sunspots appear at latitudes of about 30 degrees, both north and south of the equator.
What refers to the violent explosion on the Sun’s surface?
A solar flare is a violent explosion in the Sun's atmosphere with an energy equivalent to tens of millions of hydrogen bombs.
What happens in the corona of the Sun?
The corona is the outermost layer of the Sun's atmosphere where strong magnetic fields bind plasma and prevent turbulent solar winds from escape. The Alfvén point is when solar winds exceed a critical speed and can break free of the corona and the Sun's magnetic fields.
What are the explosions on the Sun called?
Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.
How many explosions happen on the Sun?
About 1 CME occurs every 3 days at solar minimum and up to about 3 CMEs a day at solar maximum! They can be launched at any location on the Sun but during solar minimum they are most commonly produced at the equator.
What are the eruptions of the Sun called?
Sunspot activity generally follows an 11-year cycle, called the “sunspot cycle.” A solar flare is a violent eruption of plasma from the chromosphere of the Sun that is whipped up by intense magnetic activity.
What types of eruptions happen within the Sun?
Eruptions on the Sun usually come in one of three forms: a coronal mass ejection, a jet, or a partial eruption. Coronal mass ejections – CMEs – and jets are both explosive eruptions that cast energy and particles into space, but they look very different.
What is a supernova explosion?
A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun. As these stars burn the fuel in their cores, they produce heat.
What’s the most powerful star in the universe?
A magnetar is an exotic type of neutron star, its defining feature that it has an ultra-powerful magnetic field. The field is about 1,000 times stronger than a normal neutron star and about a trillion times stronger than the Earth's. Magnetars are, by far, the most magnetic stars in the universe.
What will happen when the Sun explodes?
Effectively, the Sun as we know it will have died. When that happens, the Sun will become a red giant. It will stop creating heat via nuclear fusion. NASA says the core will become unstable and contract around this time.
What year will the Sun explode?
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies.

What happens when sun explodes?
When that happens, the Sun will become a red giant. It will stop creating heat via nuclear fusion. NASA says the core will become unstable and contract around this time. Once the core starts to become unstable, the outer layers of the Sun will expand.
What are solar flares on the Sun?
A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
Which part of the globe receives the most intense heat from the Sun?
Equatorial RegionsThe Equator, at 0° latitude, receives a maximum intensity of the sun's rays all year. As a result, areas near Earth's Equator experience relatively constant sunlight and little solstice variation.
