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
Black holes are one of the most frightening phenomena that exist in space. Their gravitational force is so strong that they distort space and time beyond possible limits.
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
As the prospect of a permanent colony on Mars is getting closer with every new press release from the Mars One project, it probably makes sense to remember that any person who will move permanently to Mars will most likely die untimely and painful death.
Here are some things that are most likely to cause it (all kinds of technical problems are excluded from consideration):
First of all, the Mars colonists will be subjected toradiation before having set foot on the threshold of their new home. Technically, the radiation level Continue reading
European and U.S. astronomers discovered traces of water on Ceres, a dwarf planet and the biggest and most spherical asteroid in our solar system.
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
A cup of hot coffee put in refrigerator cools down instantly. Similarly, if the sun was suddenly “switched off”, which in reality is physically impossible, the Earth, compared with the surrounding space, would remain hot for several million years after that. However, the inhabitants of our planet would feel the cold much earlier.
Within a week, the average global temperature of the surface would drop to 17° Celsius, and within a year – down to 40° C below zero. The upper layers of the oceans would freeze, but the ice would keep the water in the depths of the oceans warm and would prevent freezing for hundreds of thousands of years. Continue reading
Scientists are surprised, referring to a shine coming from a small part of the “Comet of the Century”, which, however, seems to be heading towards disintegration.
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
Initial observations indicate that the ISON dissolved as passed at a short distance from the Sun.
According to the latest observations, the “comet of the century” does not seem to have survived the most critical night of its life.
The first data from space telescopes show that the comet ISON probably dissolved on Thursday night as it passed at a short distance from the Sun. 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
Astronomers announced when exactly the magnetic field of the star will change to the opposite polarity, and what troubles it can cause to the inhabitants of the earth.
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 is full of mysterious and scary phenomena, from stars that suck the life out of their own kind to giant black holes which are billions times larger and more massive than our Sun. Below are the most frightening things that exist in outer space.
The ghost planet
Many astronomers say that the giant planet Fomalhaut B has sank into oblivion, but it seems to have recently resurfaced.
Back in 2008, the astronomers used NASA’s Hubble Space Telescope and announced the discovery of a giant planet that orbits a very bright star Fomalhaut, which is only 25 light years far from Earth. Some other researchers questioned this finding later, claiming that the scientists actually found Continue reading
