The OSIRIS-REx spacecraft sampled from the surface of the Benue asteroid.

  On October 20, the OSIRIS-REx spacecraft touched the surface of the Benue asteroid, the NASA team on Earth confirmed a successful touchdown at 6:08 pm EDT, the OSIRIS-REx spacecraft touched the asteroid for 6 seconds, the OSIRIS-REx mission.  Captured on October 20, during the KT Touch-and-Go (TAG) sample collection program, this series of 82 images depict the field of the SAMCAGER imager as NASA's spacecraft approaches, and on the surface of the asteroid Bennu  Touches down. This is the first spacecraft that has touched an asteroid. The mission aims to sample dust and pebbles from the surface of the Benue asteroid, and return to Earth. OSIRIS-REx project manager Rich Burns states, "We will use a combination of data from TAG and post-TAG images and mass measurements to assess our confidence that we have sampled at least 60 grams  If OSIRIS-REx spacecraft has collected 60 grams of sample, we will decide to prepare the sample on 30 October. As we know, the Bennu is a...

The gravitation of the Earth and the Moon share a magnetic shield, which protects their atmosphere.

The moon is the satellite of the earth, we all know this very well, it is only because of the moon that life in the earth is possible, or possible. Scientists believe that the moon protects us like a shield, it protects the earth from the loss factor rays coming from the sun. As we know, our Earth was not like today, 4 billion years ago, it was burning, a fireball at that time, we have faced many situations from that time to this time. The Earth is formed 4 billion years ago, and the Moon is formed 100 million years after the Earth was created, only life after the Moon was made possible. If a planet does not have a satellite, will life be possible in that planet?  Is satellite a boon for the planet?  How does the satellite's gravity force work for the planet.  In this article, I will analyze these questions, and we will know how much the moon has and does not affect the earth. If we look at the history of the Earth, we find that four and a half billion years ago, the surf...

Massive stars are factors for material for life

  Water, ammonia, methane, and acetylene play a major role in the formation of a planet like Earth, and a planet is formed when a giant star ends.  Before understanding the formation of the planet, we try to understand broadly the understanding of the formation of stars, how the stars are made, what reacts.  The stars are formed by the universe-spanning dholes, particles, gases, etc. Due to gravity, the dholes, particles, gases accumulate in one place, and form discs, which contain hydrogen gas, helium gas. The stars derive molecular energy mainly from the carbon cycle or protein through the methods of proton reaction, and in this process the hydrogen particles of the stars are broken down into helium.  After this, the stars get heat from shrinkage.  Molecular reactions also begin in helium molecules when the internal heat is greatly increased by shrinkage.  Also, stars get energy for a long time.  According to this process, the main basis of the life ...

The image of the galaxy NGC 5643 is captured by the Hubble telescope.

NGC 5643 was first seen on May 10, 1826, the NGC 5643 Galaxy was reported by James Dunlap with his 9-inch reflector telescope, and described it as extremely faint. A few days ago an image of NGC 5643 was captured by NASA / ESA Hubble Space Telescope, in the image above we can see that in this magnificent image is the spiral galaxy NGC 5643 in the constellation of Lupus (Wolf). Researchers said that it is not easy to see NGC 5643 as good; Researchers therefore needed to produce images of such a high degree of detail and beauty, with Hubble's high resolution and clarity, 30 different exposures for a total of nine hours of observation time. NGC 5643 is about 60 million light years away from Earth, researchers say, and a supernova event (not visible in this latest image) has recently occurred on NGC 5643, which has been its host. Researchers say that NGC 5643 had a specific type of supernova (2017cbv), which steals so much mass from a white dwarf star, that it will become unstable, or ...
