The Earth is Doomed to Fall Into Sulfur Rain

The Earth is Doomed to Fall Into Sulfur Rain

Space
Scientists at Nasa are afraid that we will face the same fate as the planet Venus. A new research report by Nasa reveals a potentially bleak future for our planet, writes British Metro. "Venus can be an indication of what a future might look like on Earth," says Giada Arney, NASA researcher and Stephen Kane of the University of California. They believe it is important to study Venus in order to understand how our planet can develop in the future, especially how our environment can be affected by the greenhouse effect. Venus is the nearest neighbor of the earth and is almost the same size. But unlike our planet, Venus is the hottest planet in the solar system, with an atmospheric temperature that can reach 462 Celsius and clouds consisting of sulfuric acid. However, the resea...
Water Vapor Found on Promising Terrestrial Planet

Water Vapor Found on Promising Terrestrial Planet

Space
Water vapor in the atmosphere gives hope that K2-18b may have liquid water. The exoplanet is also the habitable zone. It provides the best potential for life that has been found so far. A number of interesting exoplanets have been mapped recently, but now University College London has analyzed data on the most promising candidate for life so far. K2-18b is 111 light years from Earth. The Hubble Telescope has detected water vapor in the atmosphere, and it is the first planet outside our own solar system to have this - giving hope for liquid water. The planet is in the habitable zone, as seen from the red dwarf star in the solar system, where water can have a liquid form. There is no "other earth", says astronomer Angelos Tsiaras, lead author of the study, according to the Washin...
New Planet Forces Scientists into New Theories About How Planets are Formed

New Planet Forces Scientists into New Theories About How Planets are Formed

Space
A Swedish research group has played an important role in the discovery of a new type of planet. The unusual celestial body GJ3512b has led to new theories about how planets are formed. The unique thing about the planet is its size. Never before has such a large planet been found around such a small star. The discovery, now published in the journal Science, has forced scientists to reevaluate theories of how planets are formed. "We have come to the conclusion that the planet cannot have been formed by classical theories," says Anders Johansen, astronomy professor at Lund University. Has collapsed According to the classic explanation, planets are formed by dust particles colliding with each other and then gradually forming larger bodies. But then the newly discovered planet, named GJ...

Musks Spacex Can Send People to Space 2020

Space
Elon Musk's space company SpaceX may send people from the US to the space station ISS during the first quarter of next year. This is what Nasa chief executive Jim Bridenstine says during a visit to the company's headquarters, with the flap of "everything goes according to plan" in the upcoming tests. The collaboration with Nasa will be the first time Spacex is attempting a manned spacecraft and the first time Nasa will send astronauts from the United States to the ISS since 2011. Since then, the Space Agency has paid to take Russian vessels to the station. Elon Musk and NASA chief Jim Bridenstine have previously argued publicly about the project - Bridenstine has complained via Twitter that Musk's construction of the space capsule has dragged out at the time. Musk then blamed N...
It is Common for Exoplanets to Have Water

It is Common for Exoplanets to Have Water

Space
Researchers have investigated the chemical composition in the atmosphere of 19 exoplanets. In fourteen of them, large amounts of water vapor were detected. The University of Cambridge has led a team of scientists who have looked at atmospheric data from 19 exoplanets to compile the temperatures and chemistry of the planets. It is the most thorough study of its kind. The study included everything from small versions of Neptune that are only ten times larger than Earth, to super-Jupiter whose size is 600 times larger than our own planet. The temperature range of the planets has been between comfortable 20 degrees and a glass-melting heat of 2,000 degrees. Of course, the most interesting aspect was the presence of water. The researchers conclude that the presence of water vapor is no...
The Satellite Will Hunt Planets Outside the Solar System

The Satellite Will Hunt Planets Outside the Solar System

Space
A European satellite has been launched into space from French Guiana to explore planets outside our solar system - so-called exoplanets. The telescope, which was named Cheops, was postponed by the Russian Soyuz craft and will observe stars outside the solar system known to have planets, according to the European Space Agency Esa. It aired on Wednesday morning, a day later than planned, as technical problems were discovered just over an hour before the scheduled departure on Tuesday. The telescope measures 30 cm in diameter and has been designed to measure the density, composition and size of several planets. The goal is to study how the planets are constructed, which is considered a major step in the work of figuring out what is needed for life in places other than the earth. It c...
Harvard: Block the Sun Chemically to Curb Global Warming

Harvard: Block the Sun Chemically to Curb Global Warming

Earth
Filling the lower stratosphere with sulfate could reflect sunlight - and slow down the planet's warming. According to Harvard researchers, it costs just over $ 20 billion a year to spray the entire earth. A dissertation published in Environmental Research Letters explores the possibilities of curbing global warming by spraying the lower stratosphere with sulfate - that is, salts of sulfuric acid. It acts as an artificial volcanic eruption. In the event of major eruptions, the planet has been effectively cooled down, and at the largest it is presumed that the excluded sunlight has contributed to the Earth's ice ages. The ash clouds contain, among other things, sulfur dioxide, which forms sulfate aerosols. The Harvard dissertation states that a similar effect can be achieved chemically...
Facebook is Buying Technology – That Can Almost Read Your Mind

Facebook is Buying Technology – That Can Almost Read Your Mind

Technology
The social network acquires startup company CTRL-labs, which has developed a solution for controlling computers with the brain. The deal is said to be in the multi-billion class. For four years, CTRL labs have been working on developing a wristband that will use brain signals to control computers. When you want to touch the hand, for example, to move or click the mouse on the computer, neurons from the spine are sent out to the hand. The idea is for the bracelet to capture the signals on the road and translate them into instructions for a computer. “This is what our interactions for us and ours can one day look like. It is changing the way we connect, ”Andrew Bosworth, responsible for Facebook's virtual and augmented reality efforts, writes in a comment. The new acquisition wil
Facebook Makes Operating System – Should Replace Android

Facebook Makes Operating System – Should Replace Android

Technology
The company no longer wants to rely on Android. The new operating system will run on Facebook's own hardware. With ever heavier investments in hardware, Facebook has now decided to build its own operating system. Currently, Facebook relies on Google's operating system, Android. - We want to make sure there is room for us in the next generation. We do not believe that we can trust the market or that our competitors make it so, says Andrew Bosworth, Facebook's hardware manager, to technology site The Information. Facebook has a product suite called Portal, which mainly consists of video call screens and has built-in digital assistants. But with "the next generation," Bosworth is probably talking about the company's commitment to virtual and augmented reality. Facebook already own...
The Researchers Discovery: The Earth’s Atmosphere Extends Past The Moon

The Researchers Discovery: The Earth’s Atmosphere Extends Past The Moon

Space
The boundary between the Earth's atmosphere and space goes far beyond what we have thought so far. In fact, far above the moon. The Earth's atmosphere is difficult to examine as it is so extremely thin in the boundary of space. But now a research group has used data from the Solar and Heliospheric Observatory (SOHO) satellite, which is co-owned by ESA and Nasa, and discovered that the outermost atmosphere extends far beyond what the experts so far thought. The outermost extension of the atmosphere, the exosphere, consists at the far end of a thin cloud of neutral hydrogen, which in English is called geocorona. It is this field that researchers have now discovered is further away, Nasa reports. The moon moves in the middle of the atmosphere So far, the conclusions have been that t...
