Laniakea – The Name of Our Home Supercluster

Laniakea – The Name of Our Home Supercluster

  Group of astronomers have discovered that our own Milky Way galaxy inhabits the outskirts of unknown, until now, massive galactic supercluster, reports the Nature magazine. They named it Laniakea that comes from Hawaiian and means “immeasurable paradise”. (watch the video bellow) The discovery was made with the help of a new mapping technique that combines not only the distance between neighboring galaxies, but their relative motions. The technique has allowed astronomers for the first time to clearly delineate exactly where one supercluster of galaxies ends and where another begins. The new map shows that the Milky Way  among with the...
The March 2017 Night Sky

The March 2017 Night Sky

February is already history and it is time to look what is going to happen in the night sky in March 2017. Venus will have half a month to descend to the Sun and if succeeds (for now there is no reason to not) will no longer be visible after sunset in the west. For all its lovers I have to say that if you want to see it again, you need to twist your head east just before sunrise, but after a month. Mars is moving away, but we’ll still see in March. It follows Venus in the west,...
Saturn’s Rings Closer than Ever Before

Saturn’s Rings Closer than Ever Before

  The NASA’s spacecraft “Cassini” made one of the closest and detailed images of Saturn’s rings. Their level of detail is unprecedented. Currently runs the last mission of “Cassini” in which the machine will have to pass between the Saturn’s rings. This should be done in April. Pictures of rings A and B are quite impressive and can even distinguish small touches that usually are not visible. The small white vertical gashes visible in the image of ring A, NASA has chosen to called propellers because of their shape. They indicate imbalance in gravity near the ring caused by the...
Other “Solar System” with 7 Earth-Like Planets was Found by NASA

Other “Solar System” with 7 Earth-Like Planets was Found by NASA

Yesterday NASA announced one of the most significant discoveries of potentially habitable planets in recent years – The first known system of seven planets the size of Earth orbiting a Star. Three of those planets certainly are in the habitable zone – the area where a rocky planet could have liquid water. This discovery sets a new record for the largest number of planets in the habitable zone around a single Star outside the solar system. All seven of these planets can have liquid water – the key to life as we know it in the right weather conditions, but...
Kissing Double Star

Kissing Double Star

Astronomers have faced a very rare cosmic phenomenon in which two stars are touching and are about to end their lives in a very dramatic way. In this kiss for goodbye are involved the most massive and hottest stars in a double system of this type among the few discovered by scientists so far. The system of “suns” has been marked as VFTS 352 and is located 160 000 light-years away from us in the Large Magellanic Cloud – a small galaxy “follower” our Milky Way Galaxy. Stars in VFTS 352 are so close that circle each other only for...
Black Hole – A Door to Space?

Black Hole – A Door to Space?

  If you could survive a trip inside the black hole, exactly where you would be at the end of that journey? Very likely such a journey would not be a good idea. Usually formed after the collapse of a massive star and under the influence of its own gravity, these mysterious objects from space have such strong gravitational pull that even light can not escape (after reaching a certain distance from the hole, of course). What exactly would happen to someone who “rushed” into a black hole remains unclear and subject to many scientific and not so scientific speculation,...
A Year in Space

A Year in Space

    A few months ago NASA astronaut Scott Kelly  returned to Earth after nearly one year in space. This is the first man in history who was 340 consecutive days out of the Planet. The human body  undoubtedly reacts to this huge change. Let’s have a look what happens to it. So, what can a year in space do to the human body?   Vision One of the primary things researchers will be focusing on is the effect that being in space for almost a year had on Kelly’s vision, according to Scott. Scott said the majority of astronauts...
