 New Photos Show Water Ice on Mars 😯😯🏝️🏝️ The European Space Agency (ESA) has released an eye-opening pair of new photos that show a massive crater of water ice on Mars. The crater measures 51 miles (83km) across and contains a 1.1-mile-thick (1.8km) mound of water ice all year round. The ESA estimates that the crater contains 528 cubic miles (2,200 cubic kilometers) of water ice. The composite photos of Korolev crater were captured by the Mars Express High Resolution Stereo Camera (HRSC) over a series of orbits around the Red Planet earlier in 2018 (starting at the beginning of April). During each of the orbits, the camera captured a strip of imagery. Five such strips were combined to create the two photos. 👉

Are black holes..wormholes in disguise? What can be the root cause of reality in universe? Where can we find answers to all these questions? Believe me you are not mad, scientists are searching for these answers too and mostly they see black holes keeping a lot of secrets hidden in their complexity. Maybe all the answers are hidden in it too. It can be the Pandora Box of our universe. But do black holes really are what we think they are cause our science still can't answer what it looks like inside of a black hole. Will we be able to ever find the answers of these magnificent questions?

What is the speed of Dark??? What do you think ???🙄🙄 Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness. In the context of talking about speeds, darkness is what you get after the light stops coming, and therefore travels at the speed of light. For instance, consider that you are in distant space, far from all light sources such as the sun, and you have a light bulb on the nose of your space ship. The light from the light bulb is spreading out in all directions through space at the speed of light. If you briefly turn off your light bulb and then turn it back on, there is light traveling out in all directions from before you dimmed the bulb, and behind it there is light traveling in all directions from after you dimmed the bulb. But between the two spheres of ligh

The name 'red mercury' is a code word used in the USSR nuclear weapons program since the 1950s to describe enriched lithium-6. Lithium-6 has two nuclear weapons uses: as a reactor target for production of tritium, and in the form of lithium-6 deuteride as a thermonuclear weapon material.  The code name originated because mercuric impurities contaminate the lithium- 6 during production, giving it a red color. 'Red mercury' has been identified by many European media reports as 'any of several simple mercuric compounds and tinctures offered for sale by Russian and European agents,' but none of these had any nuclear value. The uses for lithium-6 are consistent with claims about the uses of 'red mercury.' The USSR built a large complex in the early days of their nuclear weapon program to produce and stockpile lithium- 6. Some was also supplied to China in the 1950s. Russian and Western officials have both stated that no lithium-6 from Russian or Chinese inven

A moonbow (also known as a lunar rainbowor white rainbow) is a rainbow produced by moonlight rather than direct sunlight. Other than the difference in the light source, its formation is the same as for a solar rainbow: It is caused by the refraction of light in many water droplets, such as a rain shower or a waterfall, and is always positioned in the opposite part of the sky from the moon relative to the observer. 👉 Follow @map_of_science_ for more scientific facts and information

  Q-   The correct relation between the radius of curvature R and focal length f of a spherical mirror is - 1) R = f 2) R = 2f 3) R = 3f 4) R = 4f Q. A lemon kept in water in a glass tumbler appears to be larger than its actual size. It is because of - 1) reflection of light 2) scattering of light 3) refraction of light 4) polarization of light Q. Name the scientist who first used a glass prism to obtain the spectrum of sunlight - 1) C. V. Raman 2) Lord Rayleigh 3) Isaac Newton 4) S. Chandrashekhar Q. This cost of energy to operate an industrial refrigerator that consumes 5 kW power working 10 hours per day for 30 days will be - (Given that the charge per kW.h of energy = Rs. 4) 1) Rs. 600 2) Rs. 6,000 3) Rs. 1,200 4) Rs. 1,500 Q.

👉do you think the mirror universe is exist Comments your thoughts....,.. 👇👇👇👇👇👇👇👇 The mirror world, assuming it exists, would have its own laws of mirror-physics and its own mirror-history. You wouldn’t find a mirror version of yourself there (and no evil Spock with a goatee — sorry "Star Trek" fans). But current theory allows that you might find mirror atoms and mirror rocks, maybe even mirror planets and stars. Collectively, they could form an entire shadow world, just as real as our own but almost completely cut off from us. 👉 Follow @map_of_science_  for more scientific fact and information

Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, asuperfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3and helium-4) when they are liquefied by cooling to cryogenic temperatures. It is also a property of various other exotic states of matter theorized to exist in astrophysics, high-energy physics, and theories of quantum gravity.The theory of superfluidity was developed by Soviet physicist Lev Landau.

👉👉🏿Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.965% of visible light. The name is a compound of the acronym VANTA and the color black.✌🏿✌🏿

Different colours of light also travel at different speeds, and water slows light down. So as you dive down into the water, the first colour to be filtered out by the water is the slowest: red. That means that at 30 feet or so, there is no red light in the water, so red light can’t bounce off blood into our eyes. Instead, green is reflected by green pigments in the blood that are usually hidden by the reflected red light. If you went even deeper, the blood would change from green to black.💉💉

One imagines that diamonds being the hardest substance known to man should be strong enough to stop x-rays. This however is not true. Diamonds are made up of carbon entirely. The hardness comes from the from of bonds between the atoms and the rigid lattice it forms. This please note is entirely the function of electrons.
