India can't seen blood wolf moon event

This rare event will not be visible from across most parts of Asia, including India, though it can be viewed from across the America as well as parts of western Europe and Africa. What makes this event special is that a total lunar eclipse will not take place until May 26, 2021, which is a long wait.

Super Blood Wolf Moon: What is it?

Super Blood Moon happens during a total lunar eclipse when the Earth passes in between the Sun and the Moon, blocking the Sun’s light from falling directly on the Moon. However, the little light that manages to pass from the edges of the Earth’s atmosphere lit up the Moon’s surface and makes it look red.

During a total lunar eclipse, the Sun, Earth and the Moon are perfectly lined up. Also, a lunar eclipse only takes place when there is a full Moon.

The Moon appears larger and brighter during a Super Moon given it is closer than usual to the Earth. Wolf Moon is the name given by native Americans to a full moon that appears in the middle of winter.

Super Blood Wolf Moon: Can you watch this in India?

The total lunar eclipse will start 11:41 pm ET on January 20, which is around 10:11 am on January 21 in India. This phenomenon will last for 62 minutes and will not be visible in India, according to a National Geographic report. People in eastern Africa and eastern Europe will only get to see partial lunar eclipse.

The entire event, which includes total as well as partial lunar eclipse will reportedly last for three and a half hours. It can be viewed from the Americas, Greenland, Iceland, western Europe, and western Africa.

Super Blood Wolf Moon: How to watch

Though the Super Blood Wolf Moon will not be visible in India, it should be noted that one does not need special equipment to view the phenomenon. Unlike solar eclipses, a lunar eclipses can be viewed with the naked eye. For those who wish to watch this in India, they will have to rely on livestreams online.

Super Blood Moon

Super Blood Moon 

Jan 20-21,2019

The moon will be at its closest point to Earth in its orbit, lighting up the night sky as a striking Supermoon.

The eclipse will then give the moon a red glow, creating a phenomenon known as the Blood Moon.

January's full moon has been known as a Wolf Moon for thousands of years. Ancient civilisations tracked the changing seasons by the lunar months rather than the solar calendar, naming the months after features they associated with the northern hemisphere seasons including howling wolves. These names are now used to identify the full moons.

Astronomers say the Super Blood Wolf Moon Eclipse will last around three and a half hours, and a full lunar eclipse will not be seen again until May 2021.

2019 is set to be an exciting astronomical year. Five eclipses, a stunning meteor shower, a rare planet transit and a blue moon will all feature.

How fast A Rocket would have to go to leave every planet

• Take a look at this interesting animation on how fast a rocket must go, to leave every planet in our Solar system.
• Satellites and the Space Station fight gravity by going fast enough, traveling at speeds of more than 17,500 mph (28,200 km/h), to orbit around the planet indefinitely.
• But if you want to leave Earth, you have to go faster.
• Rockets, like Apollo’s Saturn, were so big, to carry enough fuel to get to the moon.
• On Jupiter, you must reach the incredible 135,000 mph to leave the giant planet, because it is ‘twice as massive as all the other planets together.’

International space station from earth

How to See the Space Station From the Ground

Depending on your location on the Earth's surface, a spacecraft's position in orbit and the time of day, you may be able to see the International Space Station (ISS) or visiting vehicles as they orbit about 240 statute miles above the planet. The space station looks like a fast-moving plane in the sky, but it will be seen as a steady – not blinking – white pinpoint of light. Typically it will be the brightest object in the night sky (except for the Moon).  It is bright enough that it can even be seen from the middle of a city!

The left column is the satellite. The next column is the local date and the local time. The third column gives the duration, or the length of time in minutes the spacecraft is expected to be visible, assuming a clear sky. The fourth column gives the maximum elevation the vehicle will achieve above the horizon (90 degrees is directly overhead). The fifth column tells the direction and elevation at which the spacecraft will become visible initially. The sixth column gives the direction and elevation at which the spacecraft will disappear from view.

Sun weight

How wide is the sun?

The Sun is 875,000 miles across, though scientists usually use kilometers, in which case it is 1,392,000 kilometers across. It is also very heavy. To write its weight in kilograms (1kg = 2 pounds, more or less) you write 2 followed by 30 zeros!


how much does the sun weigh?

The Sun is about 2,000,000,000,000,000,000,000,000,000,000 kg (a 2 with 30 zeros kg, or about 4.4 with 30 zeros lbs). Maybe you learned in your physics class what's the difference between weight and mass. For example a person of 50 kg weighs 50 kg on Earth, 8.3 on the moon, and 1354 on the Sun.



How big around is the Sun?

The radius of the Sun is about 700,000 km (435,000 miles). As you know the circumference of a circle is 2 pi r, where r is the radius. That makes 4.4 million kilometers (2.7 million miles) for the circumference. For comparison, the circumference of the Earth is about 40,000 km (25,000 miles), about 100 times smaller than the Sun.


How heavy is the sun?

The Sun has a mass of 2*10^30 kg, that is about 300,000 times greater than the mass of the Earth. Mass depends on the amount of matter in an object. Weight on the other hand, varies with respect to local gravity, however the Sun is not sitting near anyones gravitational field.


How many of earth's moon would fit inside the sun if it were hollow? ?

Well, the radius of the moon is about 1,080 miles, and the radius of the Sun is about 432,687 miles. The moon and the sun are both spheres, and math tells us how to relate the volume inside a sphere to its radius. I don't know how much math you have done, so let me just tell you the answer and you can maybe ask your teacher for more information. The answer is that you could get about 64.3 million moons inside the Sun if it were hollow.


How many saturn's could you fit inside the sun?

Almost 1600 Saturns would fit inside the Sun.


How do you determine the size of the Sun? Is our Sun the biggest?

We know the 'angular' size of the Sun - how big it is looks to be on the sky - in degrees (it's about half a degree). We can convert that into a physical size for how big it is in miles or kilometers, only by knowing how far away it is. (for example, the moon and the sun look about the same size to us on Earth but the moon is much closer so it must be smaller) If you multiply the angular size (in radians, which is another unit of angle) by the distance then you get the diameter.
How far away the Sun is is determined by a couple of methods. One is a direct measurement of its distance by bouncing a radio wave off it (radar), but this is not such a good method as the Sun's outer atmosphere scatters the waves. So the more reliable method is to combine what we know about the way the Sun's gravity makes planets move (Kepler's Laws of planetary motion), with observations of the planets' movements and radar measurements of distances to the planets, to work out the distance to the Sun. This is an indirect way of getting the distance but very accurate since it is easier to measure the distance to a planet with radar, and there are several planets which you can usefully use to make independent calculations.

Voyager 1

1. This artist's concept depicts NASA's Voyager 1 spacecraft entering interstellar space, or the space between stars. Interstellar space is dominated by the plasma, or ionized gas, that was ejected by the death of nearby giant stars millions of years ago. The environment inside our solar bubble is dominated by the plasma exhausted by our sun, known as the solar wind. The interstellar plasma is shown with an orange glow similar to the color seen in visible-light images from NASA's Hubble Space Telescope that show stars in the Orion nebula traveling through interstellar space. Image released Sept. 12, 2013. 

Jupiter magnetic field

1. The magnetosphere of Jupiter is the cavity created in the solar wind by the planet's magnetic field. Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar System after the heliosphere. Wider and flatter than the Earth's magnetosphere, Jupiter's is stronger by an order of magnitude, while its magnetic moment is roughly 18,000 times larger. The existence of Jupiter's magnetic field was first inferred from observations of radio emissions at the end of the 1950s and was directly observed by the Pioneer 10 spacecraft in 1973.

when you think of the tallest mountain ever you’re going to probably think of Mount Everest with its peak of a little over 29,000 feet (5.5 miles).  But when you  look at Mt. Everest in comparison with some of the other mountains in our Solar System it won’t even make the list.  Let’s look at some of the Solar System’s tallest mountains as measured from the base to the peak. Mons on Mars has a diameter of 270 miles andfrom base to peak hits 12 miles high.

Not only that but at the summit of this mountain the diameter is still 72 miles wide.
