Hubble has observed the collision of two galaxies, which is known as Arp 143.

The Hubble Telescope has detected the collision of two galaxies, in which there is a space triangle, forming Arp 143, in this pair of galaxies the bright, star-forming spiral galaxy NGC 2445 is on the right, and the less fascinating and less spectacular NGC 2445 on the left. With fewer stars is NGC 2444. When two galaxies pass each other, their chances of a collision increase, such a collision can be seen as an interacting pair. Regarding the NGC 2445 galaxy, researchers suggest that NGC 2445 contains a newborn star, which ignited a distinctively shaped firestorm of formation, including thousands that are in their final stages, and that this galaxy is filled with new stars. Because there is a lot of gas in it, which is responsible for the formation of new stars.  NGC 2445 could not escape the effects of its companion NGC 2444's gravity, And the gravity of NGC 2444 is pulling the gas of NGC 2445 towards itself. NGC 2444's gravity pulls gas from its companion NGC 2445, then it fo...

TRAPPIST-1 There are 7 planets in the Solar System, out of which 5 are the size of Earth.

In 2017, on February 22, NASA announced a solar system whose star is a red dwarf star, which is orbited by Earth-sized planets, this solar system has seven Earth-sized planets, and this solar system  The star is known as TRAPPIST-1.  This solar system of TRAPPIST-1 is one of the unusual planetary systems discovered beyond our Sun, can there be life in any of the planets of TRAPPIST-1's star system, are any of its planets habitable. TRAPPIST-1 is a supercool dwarf star located in the region of the constellation Aquarius, it is slightly larger than the planet Jupiter in our solar system and cooler than our Sun, and less than 10% its size, it is about 39.5 light-years away from the Sun. Five years after the first discovery, the planets of TRAPPIST-1 are still enigmatic, with researchers' studies showing that the solar system of TRAPPIST-1 may be almost twice as old as our solar system.

To understand the environment of the Sun and the Earth, NASA is preparing for its next mission.

On February 12, NASA announced that it would place two satellites between Earth and the Sun, with the mission's objective being to understand the connection between the Sun and Earth, and how the Sun affects the space environment in some way.  Two satellites, Multi-Slit Solar Explorer (MUSE) and Helioswarm, have been selected for this science mission, these satellites will help in understanding the space environment, it will provide our deep insight on the universe, and in a way, spacecraft like  Satellites and GPS will provide important information to help protect communication signals. Thomas Zurbuchen, associate administrator for NASA, says that MUSE and the helioswarm will provide us with new and deeper insights into the solar atmosphere and space weather, adding, "These missions will not only expand the science of our other heliophysics missions,  Rather, it will also provide a unique perspective and a novel approach to understanding the mysteries of the Sun. The pur...

How dark matter affects the solar system, can it be measured?

 Dark matter is the most mysterious object in the Universe, and the strangest thing is that we cannot see it, because it does not interact with light.  No one has yet seen dark matter, but scientists believe that the Universe consists of 68% dark matter, 27% dark energy and 5% normal matter, and no one has directly tested dark matter, because it  Apart from gravity, there is hardly any interaction with normal baryonic matter and radiation, so dark matter is also considered non-baryonic. Dark matter is such an object of the Universe, which is very difficult for us to understand, if the discoverers uncovered its mystery, then we can know, how much effect dark matter has on normal matter.  Scientists believe that, just as the Sun and the Earth are gravitational forces, due to which the Earth revolves around the Sun, and the Moon revolves around the Earth, in the same way there is a gravitational force of Dark Matter, to experience it, we need to experience it.  The...
