What is the oldest thing in the universe?
Quasars are some of the oldest most distant most massive and brightest objects in the universe. They make up the cores of galaxies where a rapidly spinning supermassive black hole gorges on all the matter that’s unable to escape its gravitational grasp.
How big is the world?
6 371 km
Are sunspots causing global warming?
The peaks and valleys in solar geomagnetic activity since 1900 based on the number of sunspots observed on the face of the Sun each day (orange dots). The Sun’s activity increased in the early half of the twentieth century but it can’t be responsible for warming over the past 50 years.
How many times can Earth fit in the sun?
The volume of the sun is 1.41 x 1018 km3 while the volume of Earth is 1.08 x 1012 km3. If you divide the volume of the sun by the volume of the Earth you get that roughly 1.3 million Earths can fit inside the sun.
Are we at solar minimum?
Solar minimum is the period of least solar activity in the 11-year solar cycle of the Sun. During this time sunspot and solar flare activity diminishes and often does not occur for days at a time.

How big does Earth look from Moon?
Given the Earth’s greater size it naturally appears larger in the lunar sky. From the perspective of an astronaut standing on the Moon’s surface Earth varies from 1.8° to 2° in apparent diameter as the Moon travels from perigee (closest approach) to apogee (farthest) during its 27.3-day orbit.

Are sunspots bad for the sun?
Sunspots are generally harmless and don’t pose any health risks. Typically the only reasons to remove sunspots are cosmetic ones. However it is important to know the difference between sunspots and signs of skin cancer caused by sun damage. The most common type of skin cancer is melanoma and it is the most serious.
Is Earth smaller than the sun?
The sun lies at the heart of the solar system where it is by far the largest object. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
Can sunspots be red?
People often mistake sunspots for age spots. Age spots are the brown marks people over the age of 45 often see on their skin sunspots are red and feel scaly to the touch.

How many Earths are there?
A recent study estimates there may be up to 6 billion Earth-like planets in our galaxy. “This is the science result we’ve all been waiting for ” co-author Natalie M. Batalha an astronomer at the University of California Santa Cruz told ‘National Geographic’.
What are the biggest things in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall‘ discovered in November 2013. This object is a galactic filament a vast group of galaxies bound together by gravity about 10 billion light-years away.
What is the corona of the sun?
corona outermost region of the Sun’s atmosphere consisting of plasma (hot ionized gas). It has a temperature of approximately two million kelvins and an extremely low density. The corona continually varies in size and shape as it is affected by the Sun’s magnetic field.
How Big Can Sunspots Get?
Do sunspots make the sun brighter?
A sunspot is an area of high magnetic activity on the surface of the Sun. Sunspots produce bright light but not as much as the surface around them so they appear dark by comparison.
Is any planet bigger than the sun?
Explanation: To begin with planets as that is the easiest question to answer there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a “brown dwarf”.
Can you see sunspots from Earth?
Sunspots expand and contract as they move across the surface of the Sun with diameters ranging from 16 km (10 mi) to 160 000 km (100 000 mi). Larger sunspots can be visible from Earth without the aid of a telescope.
Does your skin change at 25?
You see as you get older your skin starts to get thinner and once you hit 25 you might even take notice of this change. Yes according to Healthline your skin can and does actually get thinner as you age. And according to Self your skin starts to show signs of aging at 25 and as it ages it can be thinner.
Can sunspots be 12 times larger than Earth?
Sunspots can be up to 12 times larger than Earth. Sunspots are surface disturbances caused by magnetic storms. Sunspots can produce flares and prominences.
Can you get sun spots in your 20s?
These so-called age spots most commonly occur in people over 50. But individuals in their 20s 30s and 40s can also develop “age spots” with prolonged and frequent exposure to the sun. So though they’re related to sunshine age spots do occur as your sun exposure accumulates with aging.
How big is the largest sun spot?
The enormous sunspot is approximately 10 000 miles across taking up just a tiny part of the sun — but still large enough that Earth could “comfortably fit inside ” scientists said.
How Big Are Sunspots?
Sunspots expand and contract as they move across the surface of the Sun with diameters ranging from 16 km (10 mi) to 160 000 km (100 000 mi). Larger sunspots can be visible from Earth without the aid of a telescope.
How old is the earth?
4.543 billion yearsSee also how do volcanoes change landforms
Is the sun bigger than the moon?
The sun and the moon are about the same size when you look at them in the sky though that’s just thanks to the coincidence that the sun is about 400 times farther away than the moon and also about 400 times bigger. Another fun coincidence is that the radius of the sun is about twice the distance to the moon.
How big is the moon?
1 737.4 km
How big is Saturn compared to the Sun?
Saturn: The Sun is 12 times larger than Saturn. 1 600 Saturn-sized planets could fit inside the Sun. Neptune: The Sun is 27.7 times larger than Neptune.
Are sunspots hot or cold?
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. The temperature of a sunspot is still very hot though—around 6 500 degrees Fahrenheit!
How large was the sunspot that developed in 2014?
A gigantic sunspot – almost 80 000 miles across –can be seen on the lower center of the sun in this image from NASA’s Solar Dynamic Observatory captured on Oct. 23 2014. This active region is the largest of the current solar cycle. On Oct.
How large are sunspots relative to the earth?
Most sunspot groups cover an area about the size of the surface of the Earth (which equals almost 170MH) but the larger sunspot groups can easily reach 1000MH or even much more than that. Image: Sunspot region 11944 at a size of 1480MH as seen by the Solar Dynamics Observatory. The Earth has been added for scale.
Do sunspots make the Earth hotter or colder?
Sunspots are areas where the magnetic field is about 2 500 times stronger than Earth’s much higher than anywhere else on the Sun. … This in turn lowers the temperature relative to its surroundings because the concentrated magnetic field inhibits the flow of hot new gas from the Sun’s interior to the surface.

Will there be another ice age?
Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1 500 years.
Is Earth as big as largest sunspot?
At 20 times the size of Earth the largest sunspot observed since the November 2003 series of solar storms is now pointed directly at Earth. Its unusually large size also means that it is now visible to the naked eye (although you should never look at the Sun without a proper filter).
What Are Sunspots?
What do sunspots on skin look like?
What do they look like? Sunspots appear as flat darker patches of skin (tan to dark brown) that are found on areas of the body that have experienced high levels of sun exposure such as the face shoulders hands chest and the backs of hands.
How cold is the Moon?
The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius) at night to 224 degrees Fahrenheit (106 degrees Celsius) during the day.
