Andomeda Galaxy

Milky Way already have collided the Andomeda Galaxy 7-10 billion years ago

By calculations of scientists through 3 billion years has to happen the collision of our galaxy of the Milky Way and the Andromeda galaxy. But astronomers think that the meeting will be not their first meeting. Hongsheng Zhao from Saint-Endru University (Great Britain) and his colleagues analyzed movement of the Andromeda galaxy and Magellanic Clouds, galaxies satellites of the Milky Way. They used the modified Newtonian loudspeaker (MoND). This theory developed by the Israeli scientist Mordechai Milgrom in 1983, explains expansion of the Universe without participation of dark matter. He noticed that the Newtonian force of gravitation works only for the bodies moving with rather big acceleration, and doesn’t operate on small accelerations. And therefore acceleration depends not linearly on the weight creating it for objects of level of galaxies and their congestions.

The first stars and galaxies of the Universe

Composition of the first stars and galaxies of the Universe

Scientists learned of what were constructed the first stars and galaxies of the Universe. Thanks to a radio telescope of CSIRO which is located in the Australian Observatory Parkes, astronomers could find the main construction material from which the first stars and galaxies of our Universe were created. BY the words of Professor Ron Ekers the telescope of CSIRO is one of the few telescopes in the world which could carry out such difficult work and find a material from which the first stars and the first galaxies in the Universe were created. It appeared that cold molecular hydrogen (H2) was the key material of forming the first stars and galaxies. It was found in early stars and galaxies with help of CO intermediary gas which radiates radio waves. To make the discovery, scientists studied the remote protogalaxies and other protoobjects of the Universe.

Andromeda galaxy

Chandra space telescope opens the secrets of the black holes in the Andromeda galaxy

The large Andromeda galaxy opens many secrets thanks to Chandra space telescope. With help of supersensitive scientific tools of a Chandra space telescope scientists managed to find a large number of candidates for the black holes in a large Andromeda galaxy. The Andromeda galaxy is the neighbor of our Galaxy. Discovery was made with help of 150 supervisions over Andromeda’s galaxy by means of Chandra space telescopes. Supervision was made within 13 years. During this time scientists found 26 candidates for black holes. Today it is a record by quantity of the black holes located in another, than our Galaxy. Some astronomers consider a galaxy Andromeda as the sister of our own galaxy and are sure that through some billions years both of these galaxies will surely face.

Milky Way galaxy map

Map of the Milky Way galaxy from Swift telescope

The space telescope Swift helped to make the unique Milky Way galaxy map.
The orbital telescope Swift, which was started in 2004 for the purpose of studying of space gamma splashes, helped scientists to create the galaxy map.
Over creation of the card worked the astronomers from the American Space Agency NASA and the State Pennsylvanian University. With help of scientific tools of orbital observatory, scientists created the detailed galaxy map of an environment of our Milky Way galaxy.

HXMM01 elliptical galaxy

Space telescope Herschel found an elliptical galaxy in the Whale constellation

In constellation of the Whale the space telescope Hershel found the elliptical galaxy representing “a transitional link” between overactive ancient “star megalopolises” and modern elliptic galaxies. As well as the fossil bird, this galaxy is peculiar “a transitional link” from one stage of development to another. The scientists studied the pictures collected by the space telescope Herschel within the HerMES program. Analyzing the images received at supervision over constellation of the Whale, scientists noticed a big bright spot. Scientists interested in an unusual spot and in detail studied it, having connected to the project a space telescope “Hubble” and land observatories of SMA and VLA.

Hydrogen gas clouds

Astronomers found hydrogen gas clouds – the bridge between the galaxies

In intergalactic space astronomers found huge threadlike clouds of gas from the ionized hydrogen, which can be the indicator of thin threads from the dark matter connecting cells of global space. The previous cycles of supervision over empty space between galaxies indicated of possibility existence of clouds of hydrogen between them. But the astronomers couldn’t determine the sizes of these hydrogen gas clouds and their property. With help of a radio telescope Green-Bank the astronomers were succeeded to understand that it not shapeless clouds, but quite accurate structures. For several weeks the astronomers watched the closest neighbors of our Milky Way, Andromeda’s galaxies and the Triangle. These “star megalopolises” drew attention of astronomers still a year ago, when they found in data of radio observations hints on existence of big congestions of hydrogen in intergalactic space. According to astrophysicists, all these clouds are located along the line connecting Andromeda and the Triangle.

Hot gas in the black hole of our galaxy

Herschel space telescope found hot gas in the black hole of our galaxy

3500-kilogram infrared space telescope Herschel launched in 1990 on height of 1,5 million kilometers over Earth, made interesting discovery. During long supervision over our galaxy, the European astronomical observatory recorded hot molecular gas, which falls into a supermassive central black hole. Our local black hole is located in the region known under the name Sagittarius of A *. This compact radiation source is at distance about 26 000 light years from our Solar System. The mass of the central object makes 4,3 million mass of the Sun. The huge number of a dust lays in the plane of our galaxy between its edges and the center, complicating us and our orbital telescopes the most part of visibility in the visible wave range.

Starburst galaxies In the Dragon constellation

The astronomers found starburst galaxies In the Dragon constellation

The American astronomers found rather small galaxy of HFLS3, stars in which were formed in two thousand times quicker, than in our Milky Way that allows ranking it as a new class of super-starburst galaxy in the early Universe. According to the astronomers, this galaxy is the certificate of that, that in the very ancient time, through only 800 million years after the Big Bang, there were possible rough episodes of a star formation. The scientists managed to track one of the most important eras in the history of development of the first galaxies of the Universe. The astronomers found HFLS3 starburst galaxy with super speed star formation, studying the data collected by a land radio telescope of VLA and orbital observatory Hershel during supervision over constellation of the Dragon. In these pictures scientists noticed rather bright point, which range was strongly stretched because of huge distance, which light passed from its source to observers on Earth.

Galaxy NGC660

Unusual Galaxy Photographed from Gemini Observatory

Astronomers from Observatory “Gemini” received the most detailed to date image of the unusual galaxy NGC 660, relating to a rare class of polar galaxies. The galaxy NGC 660 is located at a distance of 40 million light years from Earth near the constellation Pisces. It is as if two separate star clusters: the spiral and lenticular. Such galaxies are called polar – they rotate the outer ring over the poles of the internal cluster. In addition, NGC 660 is the only other known polar galaxies in which the center has an old lenticular congestion. All polar galaxies are a result of the interaction of two separate star clusters. Some of them can be formed by the collision of two galaxies formed (for example, a galaxy can be formed by a merger in the future, with the Milky Way Andromeda).
