Asteroid 2014 YB35 will safely pass Earth at 4.5 million km on the morning of Friday, March 27. 

There are ways to report on occasional close approaches by near-Earth objects (NEOs) that convey the respectful awareness of their presences and the fact that our planet shares its neighborhood with many other objects, large and small… and that sometimes their paths around the Sun bring them unnervingly close to our own.

Then there’s just straight-up over-sensationalism intended to drum up page views by scaring the heck out of people, regardless of facts.

Apparently this is what’s happened regarding the upcoming close approach by NEO 2014 YB35. An asteroid of considerable (but definitely not unprecedented) size – estimated 440-990 meters in diameter, or around a third of a mile across – YB35 will pass by Earth on Friday, March 27, coming as close as 11.7 times the distance between Earth and the Moon at 06:20 UTC.

11.7 lunar distances. That’s 4.5 million kilometers, or almost 2.8 million miles. Cosmically close, sure, but far from “skimming”…and certainly with no danger of an impact or any of the nasty effects that would be a result thereof. None. Zero. Zilch. NASA isn’t concerned, and you shouldn’t be either.

4.5 million kilometres away and it is "skimming" Earth? The Moon comes within 365,104 kilometres at it's closest approach. Just shows how the Worlds media is full of idiots selling stories to the gullible.

Monster Black Hole Discovered at Cosmic Dawn

I just read an intriguing news.
Scientists say they have discovered a black hole so big that it challenges the theory about how they grow.

This extremely massive black hole dates from a time when the Universe was less than 900 million years old. The result provides insight into the growth of black holes and galaxies in the young Universe.

The black hole was discovered by a team of global scientists, led by Xue-Bing Wu at Peking University, China, as part of the Sloan Digital Sky Survey

Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time. The international team led by astronomers from Peking University in China and from the University of Arizona announce their findings in the scientific journal Nature on Thursday.

Over the years, Google translator has improved and the service will improve in the future, I'm sure. I run two scientific blogs in Italian; I can't translate my articles in English because I would spend too much time to do it.

Spring Solar Eclipse Visible In Europe on March 20

During the morning of March 20, 2015, a total solar eclipse will be visible from the Faroe Islands, located northwest of Scotland, and the Svalbard Islands, located east of Greenland. At the same time, surrounding regions of Europe, northern Africa and northern Asia will be treated to a partial solar eclipse.

A solar eclipse occurs when the moon passes between Earth and the sun, casting a shadow over Earth. The moon’s shadow masks the solar surface and blocks sunlight from reaching Earth directly – but the amount of sunlight blocked depends on location. For example, on March 20, those in Glasgow, Scotland, will see about 94-percent of the sun blocked by the moon. The unblocked sunlight will appear as a thumbnail sliver. In Paris, the moon will block about three-quarters of the sun at the time of maximum eclipse.

Not only are eclipses an engaging sight, but they also have provided a slew of important science results through the ages. Total solar eclipses block the entire disk of the sun so the faint solar corona, the sun's atmosphere, can be seen.  In fact, before the 20th century, eclipses were the only way humans could see the corona.

The animated image shows the path of the March 20, 2015 solar eclipse.
The blue, half-oval, shadow shows the regions where a partial eclipse will be visible. The thin black line shows the area of total eclipse.

Records of ancient solar eclipse observations date back to around 2,000 B.C. Before astronomical photography, astronomers and talented recorders drew solar details of eclipses. This gave observers only a few minutes to sketch the sun’s corona, before the total eclipse was over – but the results led to tantalizing glimpses of how variable and dynamic that atmosphere was exciting the curiosity of early scientists.

Here, in Italy it's 10:06 a.m.

What do you think of this mesmerizing animation?

The author named it: 130921. Actually, all of his creations are marked by numbers.

What name would you give it?

Distant supernova split four ways by gravitational lens

BERKELEY — Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes.

A University of California, Berkeley, astronomer has now found that one of these lenses – a massive galaxy within a cluster of galaxies that are gravitationally bending and magnifying light – has created four separate images of a distant supernova.
The so-called “Einstein cross” will allow a unique study of a distant supernova and the distribution of dark matter in the lensing galaxy and cluster.

Hubble Sees Supernova Split into Four Images by Cosmic Lens (STScI press release) >>
http://hubblesite.org/newscenter/archive/releases/2014/2015/08/

Image explanation
In this Hubble Space Telescope image, the many red galaxies are members of the massive MACS J1149.6+2223 cluster, which creates distorted and highly magnified images of the galaxies behind it. A large cluster galaxy (center of the box) has split the light from an exploding supernova in a magnified background galaxy into four yellow images (arrows) to form an Einstein Cross.

Astronomers now use massive galaxies and clusters of galaxies as magnifying lenses to study the early universe, but until now had never observed the brief flash of a supernova. UC Berkeley postdoc Patrick Kelly found such a supernova in images taken last year by the Hubble Space Telescope, split into a rare Einstein Cross.

With the "four dimensions" I was thinking of what media can do of it! There is business everywhere. I'm really try to speak about the subject more than who's the best, the most beatiful in this world. English-spoken also have an advantage they can use against those who have an other language as their native tounge. Google don't let you easily redigate(?) simple wrong-spellings or accidents with the "tangentbord".

Introduction
I teach mathematics and science and I write for "Scuola e Didattica"- Educational fortnightly magazine in Italian (Editrice La Scuola).

I'm also interested in web 2.0, social network and much more. I love reading, writing, painting, photography, good music, and more.

My posts are prevalently about Science and Mathematics for a general audience, but also about Art, beautiful images/photo and interesting  gifs. I share often scientific news that can be useful to many people.

I would like to look at the profiles of everyone who circles me, but there are too many. ;)
Anyway, I will definitely look at your profile if you engage with my posts.

Furthermore, I am interested in following people who post quality original content, regardless of the number of their followers. 

Instead I am not interested in following people if they never engage with my own content.

If you consider interesting my posts, you can circle me:). I'd like to read your posts and to interact with you here on Googleplus
Bragging rights
I experimented at school a research scholarship in Science, producing approximately over 200 pages of Materials for Science, published by IRRE- ER (Institute of Educational Research Emilia-Romagna, Italy). I was also part, along with 50 teachers selected nationwide, of The SENIS Project, a pilot project from Ministry of National Education for improving the scientific formation of teachers at secondary school. This Project has collected a lot of educational resources, published in a book by Ministry of National Education.
