The Orion Nebula is the only nebula visible from Earth with the naked eye

The Orion Nebula is a diffuse nebula situated south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky.

A nebula is an interstellar cloud of dust, hydrogen, helium and otherionized gases. The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features.

The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust.

Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizingeffects of massive nearby stars in the nebula.

Orion’s nebula might hold the answer for many of the millions of questions about the universe.

Here comes the comet that will dazzle the Moon

Comet ISON is racing through the solar system, and 28 November will be only one million kilometers from our star. This will cause a cosmic spectacle since the ice in it evaporate and form a characteristic tail. Some scholars argue that will outshine the moon.

Comet ISON high speed travel through the solar system, and astronomers can not wait 28 November because, as they say, cause a real cosmic spectacle.
 
The heavenly body will then undergo incredibly close to the sun , which will cause the evaporation of ice within the comet which will result produce characteristic and clearly visible tail.
 

Using a network of telescopes Russian International Scientific Optical Network ( ISON ) comet was first discovered in September last year. When 28 November is gone along with the sun , the stars of our being is only a million kilometers, which is 150 times smaller distance of Earth from the Sun.

 That the whole situation even more interesting , ISON will pass 100 times closer to the Sun than in 1997. flew the Comet Hale - Bopova , which is 18 months could be seen with the naked eye. Close to the sun will also heat up the comet , composed of ice, metal and stone to 2,760 degrees Fahrenheit, so it will be much brighter than most comets , and some scientists say we could not overshadow the Moon .

Scientists just discovered a new human body part!

And you thought we knew everything we could know about body parts. Thanks to new technology, scientists have discovered that our eyes' corneas don't have 5 layers, as previously believed, but rather 6.
The new layer, called Dua's Layer is only 15 microns thick. If that doesn't mean much to you, consider that this layer is smaller than beach sand and mist. The cornea itself is only 500 microns thick, but is incredibly tough and strong.
The new discovery will lead to entire ophthalmology textbooks being rewritten, as well as probably better surgical treatments for certain problems that are caused by the tearing of this previously unknown layer.

Russia - U.S. shield against asteroids

Last month, the United States and Russia, a decade-long nuclear-athletes have signed a very important agreement on strategic nuclear partnership aimed at developing nuclear weapons capable of defending the Earth from dangerous asteroids, writes Daily Mail.
The main objective of the agreement is "to develop an international system of defense against asteroids."

As experts say, the agreement is a step closer to creating a technology that will soon provide protection from the heavenly bodies that can destroy life on Earth.

The agreement, which creates a legal framework for cooperation between scientists in the United States and Russia signed a U.S. Secretary of Energy Ernest Moniz and general director of the Russian federal state-owned Sergei Kiriyenko.

- This agreement creates a space for scientific cooperation and the process of building the relationship between research and technical communities the U.S. and Russia - said during the signing Monic.


The idea of ​​signing, dating back in 1995. , when they met the designers of nuclear weapons from the United States and the former Soviet Union and concluded that the threat of an asteroid impact is present, and that it should be taken very seriously and find a way to fight it.

It's been more than 18 years, astronomers have since found more than 10,000 asteroids that could one day be able to collide with our planet. Almost nine percent of these celestial bodies, potentially threatening the Earth long as more than a kilometer away, which means that their attack caused extensive damage to our planet.
 
Using weapons that Earth has, warn scientists would need to know for an asteroid the decade ahead, and to successfully defend.

If the strike out later, there would be no time to complete a successful response, but well-placed nuclear strike was not enough to avoid the destruction of life on Earth.
 


With no defense for 700,000 years we will perish like the dinosaurs

According to calculations of scientists, impact similar to that which killed the dinosaurs can be očekujei the next 700,000 years. But experts point out that even small rocks, long, between 100 and 300 meters, could wipe out the planet for entire cities and nations.

The core of our galaxy is about to explode

It seems that there is nothing so peaceful as the scene of the Milky Way in the summer sky - or at least so we thought. In reality, the center of our galaxy is a mess, made from stars that are spinning with incredible speed, super nova remnants and highly magnetised neutron stars. All these orbits around monstrously large black hole with a mass of 4 million times the mass of the Sun.

And things will soon become more violent. Astronomers have detected the gas cloud, called G2, which decays to hasten towards the center of the black hole. Later this year, the black hole will begin to consume the gas cloud. As gas slowly accelerates to incredible speeds, it collides with other things that come to meet him, is heated and radiate incredible pace.

A similar event 10 years ago created so intense outburst of light that was as bright as a million suns. We know this because the light echoes still refuse the center of the galaxy.


Judging by the astronomer
Shep Doeleman, the upcoming event is expected to last a year or more, and he classifies as a matter that we will experience a once in a lifetime.

Despite its enormous size, the black hole is still a thousand times too small to be able to see the Hubble Space Telescope and on top of that, Interstellar dust blocks all light.

However, the wavelength of the radio waves of about 1 millimeter can succeed and give us insight into this black hole.


International Network of radio plates

Doelman currently organizing Event Horizon Telescope, a project that should create an international network of radio plate to work as a TV. They will collect the incoming microwave radiation, which is like a light, but with a higher wavelength. It is a one-sided process - the plates will passively receive radio signals emitted by sources in the center of the galaxy.

Among the plates would be a physical connection, but the data will simultaneously come to them around the world.

The data will be collected by a super-computer and will keep them on the hard disk. He will then work with them to create, Do 2015. year, according to Doelman, picture shadow of the black hole.

All mammals, big or small, have about the same number of heartbeats in their lifetime!

A heart beat is such an individual thing. Your heart speeds up when you're exercising or when you're excited.

It slows when you sleep or are in a very calm state. Expanding this concept, heartbeats are also individual to species. Smaller creatures have faster heart beats than larger ones.

So you would expect all beings to have a different number of heartbeats in their lifetime right?
Wrong. Living creatures, despite their differences, have a similar number of heartbeats during their lifetime. This number is around 1.5 billion.

Large animals live longer but they also have slower heart beats. Smaller animals live shorter lives and have more frequent heart beats. Hence, most creatures have a similar number of heart beats.

If you think about time as measured by heartbeats, all creatures experience the same length of life - a lifespan of 1.5 billion heartbeats.

In Russia, discovered the remains of an unknown human specie

Russian paleontologists have found in the Altai, the traces of an unknown type of the first men. The study of the genome of human remains were found in the famous Denisova cave, scientists have found that it corresponds to 17% of the Neanderthal genome, and 4% belong to an unknown hominid.

Sensational discovery forces archaeologists to continue their excavations. Currently, studies are done in older layers than the finding of "denisovec."

It is not a sensation revealed by the survey. Decoding the DNA of the remains of the primitive people of Altai denisim cave, found that 6% of genes have similar modern inhabitants of Southeast Asia.


It gave the right to the head of research, academician Anatoly Derevjanko Denisovca attributed to subspecies of modern man. He also cast light on the process of division of mankind, which occurred 60-70 thousand years ago, says archaeologist Michael Šunkov:

A part of the population went to the Altai, where the remains denisovca, while others emigrated to the southeast. In addition, the transit places - in Southeast Asia, China - in the genes of the excavated remains are found traces denisovca.

On the other hand, the 6% that were found among the modern inhabitants of the south-east, saying that the "Denisovac" involved in the formation of the modern human form.


In addition, during the excavation, archaeologists discovered in a nearby cave traces of Neanderthals, who lived at the same time as the denisovec. Earlier it was thought that Neanderthals did not come this far to the east. The idea has emerged that the two hominid groups participating together in the formation of modern man, a scientist explains:

This is called. inbreeding - mixing in certain territories. Our recent work has shown that the denisovtci and Neanderthals, found in our cave, also mixed. And it's a sensational result.


Now picture the origin of humanity as follows: there are four lines of development of modern humans: Homo sapience African, Eurasian Neanderthals, Altai denisovec and oriental man - a resident of the territory of present-day China.

An earlier popular theory monocentrizma - man exodus from Africa, is seriously compromised. Seems plausible ideas about academics Derevjenka polycentrism, which is confirmed by the Russian paleontologists and archaeologists.

In the scientific world, the discovery of the remains "denisovca" is in second place after the discovery of a Higgs boson. For outstanding discoveries in the study of ancient history, 12 June 2013, Anatoly Derevjanko received the State Prize of the Russian Federation.
