Life as we know it is carbon-based, but does it have to be this way? There’s another element on the periodic table that shares some of the key properties of carbon but is far more abundant on most planets. I’m talking about silicon. So is there silicon-based life out there?
An exploration of the idea that life can actually cause the extinction of previously existing life.

Meteorites have told Imperial researchers the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of life.
They found that around half the Earth’s inventory of the volatile element zinc came from asteroids originating in the outer solar system—the part beyond the asteroid belt that includes the planets Jupiter, Saturn, and Uranus. This material is also expected to have supplied other important volatiles such as water.
Volatiles are elements or compounds that change from solid or liquid state into vapor at relatively low temperatures. They include the six most common elements found in living organisms, as well as water. As such, the addition of this material will have been important for the emergence of life on Earth.
The Kardashev scale measures a society’s technical development based on its capacity to capture energy. In 1964, the Russian astronomer Nikolai Kardashev proposed this system of measurement. The imagined scale of energy consumption is universal and includes the entire universe. Other proposals have been put forward for updating the scale since 1964, including additional power levels and criteria beyond just power itself. In a study presented at the Byurakan conference, a science gathering whose aim was discussing the Soviet Union’s space listening program for radio astronomy, Kardashev initially proposed the concept of his scale.

Part of one of the inscriptions found at Kom Ombo, a temple in southern Egypt. The image at the top of the inscription appears to show the king Seti I with the gods Horus and Sobek. Part of one of the inscriptions found at Kom Ombo, a temple in southern Egypt. The image at the top of the inscription appears to show the king Seti I with the gods Horus and Sobek. (Image credit: Egyptian Antiquities Ministry)A giant stone engraving that fits together like a jigsaw puzzle, found in a temple in southern Egypt, may reveal new information about a pharaoh named Seti I, who launched a series of military campaigns in North Africa and the Middle East after he became pharaoh in about 1,289 or 1,288 B.C., several Egyptologists told Live Science.
The engraving has both drawings and hieroglyphs on it; the engraving mentions an event that happened during the reign of Horemheb, an elite general in King Tut’s army who eventually became a pharaoh.
Archaeologists with the Egyptian Ministry of Antiquities discovered the engraving while conducting a groundwater-lowering project in Aswan; inside Kom Ombo, a temple dedicated to the god Horus and a crocodile-headed god named Sobek. The temple dates back 2,300 years; the engraving may have originally been in an earlier temple, now lost, at Kom Ombo that was located on the same spot as the later temple.

This is a comparison scale for all living things in the Universe.
The Kardashev scale is a technique for determining a civilization’s technical degree of progress. In 1964, Soviet astronomer Nikolai Kardashev suggested it. Based on the entire quantity of energy that the human species can collect and use, this scale system helps us comprehend how far the human species can progress.
Europa, here we come.
In the coming years, NASA and the European Space Agency (ESA) will send two robotic missions to explore Jupiter’s icy moon Europa.
Scientists have come up with laser technology that is capable of picking up alien signals from worlds that are far away. According to the Daily Star, the machine that is miniaturized was tailored to fit the specialized space missions of NASA. Such a device has the potential to revolutionize the long-standing search for extraterrestrial intelligence.
