    SPACE SCIENCE

    Progress in space science:

    While man, by virtue of his intellect, has managed to get to the bottom of most of the realities driven by evil and marine life and has rapidly succeeded in making their usefulness useful for his own lives, he has also mastered the mysteries of space. Not lagging behind in casting. Further progress is being made in space science, about which a few things are presented to the readers.

    Mathematics- Role in Space Science

    Scientists at the Herzberg Institute of Astrophysics have applied some mathematical formulas to information obtained from the space telescope. It has digitally created a reference image of stars without planets. When this reference form was negated from the image obtained from our galaxy, three planets appeared surprisingly. Each of these planets had 3 times the mass of Jupiter. In this way, it is possible that a planet like Earth will ever be discovered.

    Commercial supersonic flight in space

    Lockheed Martin has developed a silent supersonic ride that will take you from Chicago to Paris in just 4 hours. The ride has been developed by the German space agency DLR. The European Commission has funded a space liner project. It will travel at a speed of 14000mph and will have a capacity of 50 passengers. It will travel in space and cover the distance from New York to Sydney in 90 minutes.

    The space liner will reach an altitude of 26 miles, which is the lower boundary of space and will take only seven minutes to descend, as it will be at a very high altitude so its sonic boom will not disturb this population over which it will travel. Due to this high speed, the temperature of the space lines will reach 5400 degrees Celsius. ۔ To reduce this temperature, its body is made of porous clay like a human body. American company Virgin Galactic has started pre-booking 200 passengers, which is expected to cost a total of 30 million dollars.

    Identification of toxic waste from space

    Disposal of toxic waste is a major environmental challenge that is due to dumping the waste in restricted areas. Technology has now been developed to detect this type of waste, which will be detected by ground penetrating radar (GPR) Ground Penetrating Radar.

    It is made up of more hydrogen and helium and is running in our solar system, including the Earth. It orbits the Milky Way at a distance of 24,000-26,000 light-years, and is equivalent to a total of 225-250 million years. Its core has a temperature of 15 million degrees Celsius and its pressure is 340 billion times higher than the air pressure on Earth. Its surface temperature is 6000 degrees Celsius.

    Launch of a solar-powered spacecraft

    In 2010, Japan launched the first solar-powered spacecraft, IKAROS (Inter-Planetary Kite-Craft Accelerate by Radiation of the Sun). Solar Sail Technology was used for the central pushing force. The solar sail is 14 meters long on each side and consists of a thin polymer square membrane that looks exactly like a kite, with thin film solar cells installed in the membrane.

    These solar sails will gradually open up a few weeks after being sent into space, and the solar-powered spacecraft will travel around the planet Venus for six months, and then stay at a distance from our sun for another three years and will gather scientific information. If the experiment is successful, a new spacecraft with a 50-meter-long solar sail will be sent.

    In December 20210, one such spacecraft sent by Japan, crossed the planet Venus and thus the space program in Japan took a big turn. 

    Amazing universe

    Our universe is thought to be 713 billion years old. The universe we observe is about 93 billion light-years across. This means that light would have to travel 93 billion years to travel from one end of the universe to the other.

    ۔ There is constant evidence that the universe is constantly expanding and that its expansion is due to a mysterious force called dark energy. The vast majority of the matter that makes up the universe is not made up of something we can observe.

    These observable objects include galaxies, solar systems, and planets, but in addition to all of this there is a mysterious substance called Dark Matter. We can't observe it. There are 100 billion galaxies in our observable universe. Interestingly, the number of neurons in our brain is only 100 billion, but the more complex thing about our universe is the universe within. Each galaxy has an average diameter of about 30,000 light-years.

    Our Milky Way is slightly larger than the average size of galaxy and has a diameter of 100,000 light-years. The average distance between different galaxies is about 3 billion light years. The nearest galaxy to our galaxy is called the Andromeda galaxy, about 2.5 million light-years from our galaxy.
