Dangerous Volcano Eruption in the World (country)
Welcome to the Top10 Archive! Mother Nature has repeatedly shown itself to be a respected force. Beneath the Earth's crust, the molten rock threatens to tear apart the planet's tiny plates and flutter its surface, slicing everything in its path. While some volcanic activity causes minimal damage, others have such a profound impact on the region that they have found a place in this Top 10 volcanic eruption.

Why We Cannot Use Normal Ball Pen In Space
As the Russian cosmonaut Sergei Kud-Sverchkov explained in a space video for the Russian space agency Roscosmos, Soviet astronauts used crayons in the past, but NASA already used them when they began to use Fisher space pens. Reyes shared the original order for NASA's original order of 400 pins from Fisher with Reuters (see below).

Space Shuttle: Final Flight of a Legend. Top Story - July 2021.
IF HUMANITY HAS a beachhead to the stars, this is it: Cape Canaveral. This sandy promontory, jutting out into the Atlantic from a barrier island on the midway point of Florida’s eastern coast, is the site of most of the manned space launches in human history.

How Much Percent Of The Total Electricity Is Produced From Nuclear Energy
Within a few years, these two reactors could supply a quarter of New York City's electricity. According to the World Nuclear Association, 441 fission plants are in operation by August 2020, 54 are under construction and 109 are in planning. As of December 3rd, 2018 there were 98 operational nuclear reactors and 61 nuclear power plants in the United States.

Why Our Sun Will Become White Dwarf In The Future
Once the mass-temperature threshold is exceeded, the star begins to merge hydrogen into helium and meets one of three different destinies. These fates are determined by the mass of the star, which in turn determines the maximum temperature that can be reached in the nucleus.

Why We Cannot Capture The Photo Of Black Hole?
The Event Horizon Telescope, a planetary-scale array of eight ground-based radio telescopes created by an international collaboration, has captured images of a supermassive black hole in the center of the galaxy M87 and its shadow. The ground-breaking images were captured by Event Horizon Telescope (EHT), a network of eight radio telescopes from Antarctica to Spain and Chile and over 200 scientists. What is notable about the M87 image obtained from the EHT is that the radio dishes scattered throughout the globe were used to simulate a gigantic telescope the size of Earth.

Is Nuclear Fission Possible On Earth?
Fusion differs from fission, which has been our only way of generating electricity from atoms since the 1950s. As the price of wind and solar energy continues to fall, experts say they offer an economical and timely way to combat climate change by harvesting energy from an untested technology: nuclear fusion. The amount of energy generated by nuclear fusion is more than four times that of a fission reaction, and fusion reactions could form the basis for future fusion-powered reactors.

Why Is Hydrogen Bomb Stronger Than Atom Bomb?
Hydrogen bombs use the fusion of atomic nuclei to produce explosive energy. Like a nuclear power plant, atomic bombs are based on fission. Nuclear fission is carried out to generate more energy, which is then used to initiate nuclear fusion.

The Journey of a Black Hole: How They Form And What Happens If You Get Pulled In
The Journey of a Black Hole: How They Form And What Happens If You Get Pulled In A black hole is a region of spacetime where gravity is so strong that nothing particles or even electromagnetic radiation such as light can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
