Ghostly shape of 'coldest place in the universe' revealed

The Boomerang Nebula, called the “coldest place in the Universe,” reveals its true shape with ALMA.

The coldest place in the universe was found 5,000 light years away from planet earth in the constellation Centaurus. It has a ghost shape for and its said to be colder than the faint afterglow of the Big Bag being it one degree Kelvin (minus 458 degrees Fahrenheit). This nebula was originally observed by ground-based telescope but it was identified as the coldest place in the universe by the Atacama Large Millimeter/submillimeter Array (ALMA) by astronomers. With ALMA they determined the true shape and the properties of the nebula and revealed the whole story other from the picture taken by the Hubble Space Telescope.

The object found, called Boomerang nebula, is actually a planetary nebulae that is actually the end-of-life-phases of the stars just like our sun. What remains in their center are white dwarf stars that emit ultraviolet radiation which causes gas and a glow that lets it bright different colors. By now the pre-planetary nebula is seen by starlight which only reflects dust grains not such a big glow. The color emitted is also a character of the coldness expanding in the nebula by a gas. This information has been seen for millions of miles away by the ALMA and the Hubble telescope and many attributes and its properties can be known by this.

It's impressive how technology has evolved to the point were we can see objects that are 5,000 light years away! Personally I think this is incredible and it's amazing how we are discovering new things in the vast universe in which we know very little about. Very similar to the sea, we don't really know what is out there and because space can be very terrifying these new inventions can help the world know a little bit more about the place we live in, the universe. The nebula has very pretty colors, one of the reasons this article was very alluring but also the fact that it's the coldest place in the universe is really interesting and I just had to click and see what the fuzz was all about. I'm glad I got to know more about nebulas and learned about planetary nebulae.

Beware of the Yeti

Yeti in the Himalayas

The old legend of the yeti has been alive for many years but never confirmed. Therefore it has always been said it is a myth. Recently it is said, this past week,  that the legendary yeti has been 'discovered'. The yeti is supposedly said to be to be a giant ape-like creature that lives in the Himalayas by trekkers and mountain climbers that have "seen him". They also say it is a dark and extremely shy creature with footprints similar to human's but larger and wider. 

There minimal sustainable proof of the existence of this creature, only footprints and a few hairs that have been found and tested it different places. The conclusion that was reached with the hair testing is that the yeti is a polar bear species that was extinct 120,000 years ago.  The hairs were brown, which shows the resemblance with polar bears and grizzly bears. The two samples that have been collected are relatively far in distance which can indicate that there are more than one of these creatures or the creature moves from place to place. This evidence required has alarmed various news stories where they confirm, "It is not a bear, not anything else that we've so far been able to identify."

Clearly the mythical creature, the famous yeti, has always been an intriguing mystery to many people. Documentaries, news articles, books, movies, and other things have been created in honor of the curiosity people have towards the yeti. Being it a non-solved mystery it is very interesting to research and speculate about, and with the evidence scientist have of this "creature" it gives some sort of hope to the yeti fans. It would be an astonishing accomplishment to once in for all know if the yeti is real, and if this creature actually exist and all of it is a myth. Likely to the mermaid myths, the yeti is a mystery soon to be discovered and we will be expectant to this story.
