Let’s get to the title of this post … As mentioned above, the McMurdo Dry Valley is one of the only ice-free valleys in Antarctica where only one percent can be seen.Humidity in these arid valleys is very low, and the surrounding mountains prevent the flow of ice from nearby glaciers. These areas are covered…
Can we believe that man used a device like an analog computer two thousand years ago …? But that is the reality. One such device that still amazes researchers today is the Antiquator mechanism, which is housed in the National Archaeological Museum in Athens, Greece. In ancient times, ships sailing from Asia Minor to Italy…
How did water come to earth? Certainly not after the earth came into being. Water is older than earth. The water we use contains the hydrogen produced by the Big Bang. And the explosion of oxygen stars in it. So there is more water available in space than we think. It only tells the most…
For an object to be visible to us, its size must be greater than the wavelength of the light used. Therefore, visible light (400-700 nm) cannot be used to see objects as large as the nanometer range. But it is possible with electrons. Using Debroy’s equation, electron beams of the required wavelength can be generated….
The Spirograph Nebula (IC418) is a bright planetary nebula about 0.3 light-years across the Milky Way galaxy about 3,600 light-years from Earth in the constellation Lepus. IC 418 is named after the spirograph, a toy that makes geometric patterns on paper. Before the Hubble Space Telescope could capture images of it with a magnitude of…
The Red Planet has captured our interest for centuries, and it has been featured extensively in science fiction books and movies. Mars has been the subject of robotic exploration since the 1960s. Since 1965, NASA has been sending missions to explore Mars and sharing images and knowledge about our curious neighbor. Mars is the second…
The bones were recovered from a Neanderthal hunting camp in Navalmaillo Rockshelter, central Spain. These bones were analyzed by researcher Abel Moclan / his colleagues. Statistical analysis of the fossil record suggests that Neanderthals cooked large herds of cattle and deer in rock shelters. But they took their prey to another place and ate it….
The ground rose up to form large bubbles. They have been called the “trembling tundra” because they jiggle when stepped upon. It turns out that these bubbles have formed because methane gasses are rising into the empty spaces created by melting permafrost. Like a ticking time bomb, the pressure is building up inside these bubbles…
