The limits of our Solar System seem to be continually expanding, as the new found celestial body temporarily named «2012 VP113» is estimated to have a diameter of about 450 km and is located in the so-called Oort Cloud. This area is full of millions of moving comets and lies beyond the Kuiper Belt, a region with icy bodies like Pluto (which lost the title of planet in 2006). Continue reading
Theories about an unknown planet hidden on the outskirts of the Solar System seem to be definitively disproved by NASA’s research. The case of the so-called “Planet X” dates back to the early 20th century, when the American astronomer Percival Lowell proposed the existence of such a body in order to explain some inexplicable features of the orbit of Uranus.
When Pluto was discovered in 1930, many astronomers rushed to celebrate the discovery of the infamous Planet X. But celebrations were premature, since it was finally found that Continue reading
Therefore it begs a question what could happen if such a monster suddenly appeared or traveled to the vicinity of our solar system?
Before answering this question, let us first clarify some other questions. At what distance would it appear? Where would it come from? How massive would such a black hole be? Continue reading
The water was detected in the form of water vapor columns ejected into space possibly from volcanic geysers.
It is the first unambiguous detection of water on Ceres and, more generally, on a large asteroid belt between Mars and Jupiter. The discovery also raises the question whether the Ceres could one day be home to microbial life, although it is still too early to make assessments. Continue reading
The ISON seems to be “injured” but “alive” after the “hot embrace” with the center of our solar system.
According to the latest data available to scientists, the ISON may have lost about 3 million tonnes and is heading towards disintegration, but so far, a small part of it continues its journey into space.
What previously caused the assertion that ISON is “dead” was the fact that initially telescopes recorded Continue reading
Hoffman is one of about five hundred people who lived through the unique experience of seeing Earth from its orbit. Imagine that being in space, you can pull your hand and completely close our planet – so that all our knowledge, the whole humanity, and every person who has ever lived on Earth, simply disappear. This very clearly shows how vulnerable we are. That is why, according to Hoffman, for long-term survival of our species we need to become a multi-planetary race.
It should be understood that space is not Continue reading
The comet Ison, dubbed by the astronomers the “Comet of the Century”, will be observable in the northern hemisphere as it is getting closer to the Sun and promises a ‘once in a lifetime’ spectacle for skywatchers.
The comet Ison weighs more than 3 billion pounds and is directed towards the Sun at a speed of 377 kilometers per second. It is visible to the naked eye since the middle of November, and its sight will become more and more impressive as it is approaching the center of our solar system. Continue reading
NASA astronomers have learned when the Sun’s magnetic field will change its polarity. According to the calculations, it will happen in only three weeks, writes the “Metro”.
However, it is not a cause to wait for the apocalypse: such poles changes occur on the Sun every 11 years.
“It is not a disaster, but a large-scale phenomenon with real consequences. But it’s not something to worry about,” explained Todd Hoeksema, expert in solar physics of the Stanford University. “First, the solar magnetic field weakens till it is reduced to zero, and then it reappears again, but with reversed polarity – these processes are Continue reading
Outer space has always attracted and perplexed humans. Its mysteries fascinated, perturbed our imagination, and forced us to go deeper into the unknown. However, the more people studied space, the more mysteries they have come across. At the moment, scientists came up with seven major mysteries in space, the number of which can grow over the next decade or so.
Mystery #1: Is there life on planet Mars?
The so-called “Red planet” has long been a stumbling block for scientists. Not quite a black hole or the Andromeda nebula, located literally next door, it is causing so many questions… Continue reading
The annual meeting of the Earth with falling stars that look like if they were coming from the Orion constellation will start on October 21 and run until November 7.
This phenomenon will peak on 20 and 21 October, when and as scientists believe, about twenty meteors will be visible per hour. The Orionid shower is actually the remains of the Continue reading
