The star, which is close to Earth, grows in constellation Hydra, actively “eating” gas from the protoplanetary disk, in the same way could develop the Sun. TW of the constellation Hydra — being at distance from our planet a star age of 10 million years became about 180 light years object of research of scientists. The star weight is slightly less than Sun and have own protoplanetary disk. According to astronomers studying TW of the constellation Hydra, they will be able to understand that happened to our Sun when it was “kid”. In the work scientists used the data obtained by orbital x-ray observatory of “Chandr” and land telescopes. It became clear that for the growth of star of the constellation Hydra “exhausts” from a protoplanetary disk gas. Then the gas moves on lines of a magnetic field to star poles.
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.
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).
NASA/ESA Hubble Space Telescope new image shows NGC 7026, a planetary nebula. Located just beyond the tip of the tail of the constellation of Cygnus (The Swan), this butterfly-shaped cloud of glowing gas and dust is the wreckage of a star similar to the Sun. Planetary nebulae, despite their name, have nothing to do with planets. They are in fact a relatively short-lived phenomenon that occurs at the end of the life of mid-sized stars.
The new image shows spectacular new view of a peculiar galaxy Centaurus A, which is a sprawling elliptical galaxy located about 12 million light-years from Earth in the southern constellation of Centaurus (The Centaur). The peculiar galaxy emits strong radio emissions and is the most prominent radio galaxy in the sky, according to officials from the European Southern Observatory (ESO). Centaurus A’s bright nucleus, powerful radio emissions, and jets may be produced by a supermassive central black hole that is 100 million times more massive than the sun, astronomers have said.
New photo, snapped by the European Space Agency’s Herschel space observatory, shows Cygnus-X, an extremely active star-forming region about 4,500 light-years from Earth in the constellation Cygnus (The Swan). As said researchers in the new photo, bright white areas highlight areas where large stars have recently formed out of such clouds. These clumps are particularly evident in the right-hand side of the image, which shows a chaotic network of filaments.
While some galaxies are rotund and others are slender disks like our spiral Milky Way, new observations from NASA’s Spitzer Space Telescope show that the Sombrero galaxy is both. The galaxy, which is a round elliptical galaxy with a thin disk embedded inside, is one of the first known to exhibit characteristics of the two different types. As said Dimitri Gadotti of the European Southern Observatory in Chile the Sombrero is more complex than previously thought.
Scientists from the University of Oklahoma have identified two white dwarf stars considered the oldest and closest known to man. Astronomers identified these 11- to 12-billion-year-old white dwarf stars only 100 light-years away from Earth. According to scientists these stars are the closest known examples of the oldest stars in the universe forming soon after the Big Bang. Mukremin Kilic, assistant professor of physics and astronomy in the OU College of Arts and Sciences and lead author on a recently published paper said that a white dwarf is like a hot stove, once the stove is off, it cools slowly over time.
The Lyrids are a strong meteor shower lasting from April 16 to April 26 each year. The Lyrid meteor shower is expected to reach maximum intensity overnight from Saturday to Sunday (April 21 to 22), with the best observing opportunities coming between midnight and dawn on the 22nd local time, experts say. The moon will be nearly new at that time, so its glare shouldn’t drown out too many of the Lyrids’ brief flashes. The dark skies could make a big difference for meteor-watchers, because the Lyrids are historically a mild shower.
