NASA's SOFIA Credit: NASA / Jim Ross Stratospheric Observatory For Infrared Astronomy is commonly called as "SOFIA" , owned by National Aeronautics and Space Administration ( NASA) and German Aerospace Center (DLR) , Universities Space Research Association (USRA) . Generally SOFIA is carried by Boeing 747SP aircraft which was modified to carry a telescope. The Boeing 747SP was purchased by USRA on April 30,1997. Later on the same year it was brought by NASA. And NASA modified the aircraft and insert a telescope. They did many tests for this airborne observatory. On May 26, 2010 SOFIA started its service and it still continue to fly and doing its work well., wait! what is its work?  SOFIA's work       Image credit: NASA   SOFIA has 2.5m(8.2 ft) diameter reflecting telescope, it is designed for infrared astronomy observation in the stratosphere layer at a distance 40,000ft from the Earth. The reason for building this flying telescope is to find the celestial magnet

Starlink Network on Mars Image source: Goddard Space Flight Center/NASA/Reuters             The SpaceX founder Elon Musk introduce this mission Starlink. The aim of this mission is to provide continues internet globally with low latency at speed. Currently this is in developing stage, the mission was planned to supply only on the Earth. But in a latest interview with TIME magazine, SpaceX's president and COO Gwynne Shotwell relieve the plan of Starlink broadband connectivity to the red planet.  “Once we take people to Mars, they’re going to need a capability to communicate,” Gwynne Shotwell said during a previously recorded interview with TIME. “In fact I think it will be even more critical to have a constellation like Starlink around Mars.” Pre-planned ? Image source: SpaceX    The aim of Elon Musk is to set the humans on Mars and in fact he said that "I want to die on Mars," he said in a 2013. He was focused in his future missions to Mars. Now he launching many Starlink

  Hello, I'm Calling From the Moon!                              One of the unforgettable and the historic event of our Man kind was happened on 16th July 1969. The day where America send humans to moon. On 20th July 1969 we expland our footprints beyond our Earth. The day where first human land his feet on Moon. People of hundreds were worked for this massive mission and their work become a big success for our entire man kind. Around 650 million people have watch this event on TV worldwide. This event inspire millions of people in space science. Astronauts spent nearly 21 hours, 36 minutes on Moon.    That's one small step for man, one giant leap for mankind.        And totally there were six crewed missions (total of 12 US astronauts) to Moon and several uncrewed missions were made. We were trying to find the hidden secretes of the Universe and we see moon as the first object to observe so many countries are trying to decode the Moon. Apollo Program:            Apollo program

Scientists discovered life on Venus?         On September 14,2020 a team of researchers publish a paper that Venus have possible sign of life. Let's know briefly about Venus. Earth's Sister:   Credits: Prospect Magazine         The   hottest   and  brightest  planet in our solar system. Venus is called as "Earth's sister planet" but it is not like our Earth, the surface temperature is about 482°C, it spins opposite direction to the Earth (i.e) in Venus the sunrise in west. Venus is also called as morning star due to the brightness it can visible in naked eyes from the Earth. The size of Venus is almost equal to the Earth, the diameter of our Earth is 12,742 Km and Venus has 12,104 Km. Venus is made of similar composition of our Earth. And it has atmosphere like our Earth, which contains 96.5% of Carbon-di-oxide, 3.5% of Nitrogen, 70 ppm  of Argon, 150ppm of Sulfur-di-oxide, 20ppm of water vapor.         The surface pressure on Venus is around 85 times that on

Merge of Two Black holes:  Credit: LIGO/VIRGO/NASA Researchers at LIGO - VIRGO detected merging of two black holes which was occurred in 7 billion years ago and the gravitational shockwave reaches the earth  in May, 2019.  The researchers says that one black hole with a mass 66 times that of our Sun, and the other with 85 solar masses. The two black holes came close together, rapidly spinning around one another several times per second before collision. Collison of these two black holes produced with a mass 142 times that of our Sun. The distance to the merger was calculated to be the equivalent of 150 billion trillion km. researchers said this merging black hole is an "intermediate mass black holes" which ranges from 100 - 1000 times the mass of our sun. This gravitational wave event was named GW190521. Now they confirmed the existence of intermediary mass black hole. The signal lasting just one-tenth of a second.The signal had a frequency of 60Hz. What is a black hole?
