A black hole will be photographed in 2017

2017 will be a year of challenges for astronomy, and in particular for the study of our solar system and the galaxy it is in.With some luck it could be the year that we managed to have the first photograph of a black hole Thanks to an international project, the Event Horizon Telescope .

A black hole will be photographed in 2017

We will tell you a story that could reach a climax in 2017, but which began in 1971, when Martin Rees and Donald Lynden-Bell proposed the hypothesis that in the center of the Milky Way , our galaxy, there should be a supermassive black hole, which they named as Sagittarius A * , to differentiate it from the rest of the central sector, known as Sagittarius A, and to indicate that something very special was happening there.

Supermassive black holes are usually found in the center of galaxies and there is still no cons among astrophysicists about how they originate, but they could play a fundamental role in the stability of elliptical and spiral galaxies, such as the Milky Way.

The Milky Way

In 1974 the astronomers Bruce Balick and Robert Brown , using an interferometer-an optical instrument that interferes with the light wave, which in astronomy has been used to measure star diameters and detect planets outside the solar system-, confirmed the existence of Sagittarius A *.This phenomenon Stellar would have a mass equivalent to that of 4 million soles like ours, and a diameter of 45 AU, just a little smaller than the space occupied by our entire solar system (50).Remember that a UA, Astronomical Unit, is equivalent to the average distance between the Earth and the Sun (149,597,870.7 km).

In 2013, during a conference International astrophysics at the Steward Observatory of the University of Arizona (United States), the Event Horizon Telescope (EHT) project was launched, which would consist of taking a “photograph ”Of the supermassive black hole in the center of our galaxy.

In the center of the galaxy is Sagittarius A *

The quotes come to the case because, first, it is not a telescope, but a network of observatories in everyone , who will focus their interferometers to build an image, the “photograph”, of Sagittarius A *.All Earth would act as a single telescope focused towards the center of our galaxy.

Naturally, the black hole is not photographed, it is not possible, but its outline, the visible edge, known as horizon d e events or event horizon , hence the name of the project.

When the EHT was created it was thought that the image would culminate in years, that is, in 2018, but it is possible that I managed to complete this year, and new data on these mysterious and fascinating accidents of our universe begin to emerge.

We are getting closer to unexpected things.If you are interested in this article, do not stop reading what Hawking Think about looking for alien life and about these holes.

The mystery of prehistoric giant mushrooms

Imagine a primitive scenario , halfway between fantasy and mystery.It is a time where Earth has only two continents: Euramerica , to the north, and Gondwana , to the south.Imagine now that you are walking on a soil almost devoid of vegetation, there are hardly any plants, and your steps explode in the thicket of a rocky stage, where they stand... The authentic giants of the Earth: the prototaxites.These giant mushrooms were like strange mastiffs that could reach almost 8 meters.The higher the height, the greater the possibility of escaping their spores, and hence their sovereignty In these scenarios of Silurico and Devonico , almost 420 million years ago... But, what were they? Trees, bushes? ...The prototaxites were fungi.If you have felt a chill or have been stung by curiosity, do not hesitate to know more about these creatures worthy of appearing in the "Lost World" of Jules Verne. The era in which the Prototaxites, giant fungi, dominated the Earth Scientist...

And you, also "procrastins"?

And you? Procrastines too? If you don't, we are sure that you know someone who does it continuously and that, surely, makes you despair.But what does this disturbing word really mean? Let's give an example: you have been dating a person for a long time, you make plans for the future, you have many illusions and projects, however, your partner never seems to decide.He is unable to formalize your relationship because something like that, not only overwhelms him, but even He is lazy. "Are we not well like that?" I often reproach you. Let's give another example: you may have the classic friend who never seems to finish his studies.It is easy to be an "eternal" university student who faces the responsibilities and anxieties of the working world. And what about people who spend all their time in front of a computer screen letting out "real life" ? Sometimes, it is much easier to let ourselves go, evading responsibilities, than to put means t...

What scientists learned after studying genius children for 45 years

Started in 1971, the "Mathematically Early Youth Study," or SMPY, has tracked 5,000 of the genius children in America .It is one of the longest-lasting studies focused on gifted children that has been in history.We will tell you what they discovered. 5 things researchers discovered when studying genius children for more than four decades 1.These children Geniuses lead exceptional lives. Initially they studied the intelligence of genius children in the United States using the SAT, university entrance exams and other Intellectual Coefficient tests, then they began looking for additional factors such as university enrollment and the professional careers they pursue later in life. What enco They also showed that the most gifted children grew up to obtain doctorates and postgraduate degrees , and to register patents in a much higher proportion with respect to the less gifted children.The majority are among the top 5% of employees. According to Jonathan Wai, a psyc...

Did the Egyptians know the sperm ?!

We have dedicated many articles to Egypt, among them: "the doctors of ancient Egypt", "Hitler's bewildering love for Nefertiti", "the Book of the Dead"...Today we want to present a anecdote more than Curious: A sperm appears on an exterior relief of the Luxor Temple.After discovering it, the researchers, like you, wondered, is it really a sperm? Judging by the image, it is exactly the same as one...We discover the answer to the riddle! The sperm of the Temple of Luxor In the exterior of the Temple of Luxor There is a religious scene in which the God Amon-Min appears with a erection, ejaculating, in which a sperm is perfectly represented (as you can see in the following video).

Is it a zebra or is it a donkey? No, it's a "ceburro"

No, it is not a pun.The birth of this beautiful zeburro is the result of a hybrid cross between a zebra and a donkey. As often happens with zebras and donkeys , creating unique and sympathetic zebrasans that raise so much expectation among animal lovers. This curious phenomenon has recently originated in a small Crimean zoo, where apparently some species coexist quietly with the others, until in the end nature has played with chance to create a new tenant whom they have called «Telegraph» .If the purpose of zoos is precisely to conserve all species at risk of extinction, it seems that biology has taken a step further to offer us this little gift: the ceburro. Ceburro.The sympathetic hybrid of the zoo The ceburro born in Crimea has received the original name of «Telegraph» in honor of a newspaper of l country .As you can see in the picture his whole body is reminiscent of that of a donkey, but its legs are painted with the typical strokes of a zebra.A precious nature that, unfo...
