Astronomers claimed that they have discovered the biggest ever black hole in the small galaxy called NGC 1277 which is situated around 250 million light years away from our planet. This galaxy constitutes the mass equal to 17 billion suns. The biggest ever black hole sits in the NGC 1277 galaxy in Perseus constellation. 

Consequently, the astronomers have developed Hobby-Eberly Telescope Massive Galaxy Survey in order to know about the galaxies which are worth following up

Scientists discover dwarf planet “Makemake” with no atmosphere

November 27th, 2012

“Makemake”: A dwarf planet in our solar system discovered by astronomers.

• Orbits in the outer solar system
• Has no atmosphere
• About two thirds the size of Pluto
• Travels around the Sun in a distant path that lies beyond that of Pluto but closer to the Sun than Eris, the most massive known dwarf planet in the Solar System.

Makemake, the Massive Dwarf Planet of Solar System Has No Atmosphere

Astronomers from Instituto de Astrofisica de Andalucia, CSIC, Spain in the third week of November 2012 discovered that the distant drawf planet called Makemake, which is 2/3rd that of Pluto in size does not have atmosphere. Planet makemake revolves around sun in its distant route which lies away from Pluto. This distance is closer to sun than Eris’, the massive dwarf planet in entire solar system.

In the previous observations it was found that Makemake was quite like the fellow dwarf planets which compelled some astronomers to believe that it had atmosphere, maybe like that of Pluto. But in the new study it was discovered that Makemake does not have significant atmosphere. The team that carried out the study combined the observations from three telescopes- New Technology Telescope, Very Large Telescope and TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) at European Southern Observatory's La Silla and Paranal observing sites in Chile.

The new observations of the team will add many more details to discover about Makemake. The details will include finding the size more precisely and estimating the density of the planet.

New planet
An international team of astronomers, led by Mikko Tuomi, University of
Hertfordshire, U.K., and Tuorla Observatory of the University of Turku, Finland, and
Guillem Anglada-Escude, University of Goettingen, Germany, has discovered a new
super-earth planet that may have an earth-like climate and be able to support
life.The new planet, designated HD 40307g, exists in the habitable zone of a nearby
star known as HD 40307 and is part of a six-planet system. The system was
previously thought to contain three planets in orbits too close to the star to support
liquid water. Subsequently, the researchers identified three more planets in orbit.

Total Solar Eclipse seen in Northern Australia

A total Solar Eclipse was seen in Northern Australia on 14 November 2012. The darkness of the eclipse was at its peak for 2 minutes. Number of scientists, amateur astronomers and tourists gathered together on the hill tops and the beautiful beaches of Great Barrier Reef to have a look on of the celestial phenomenon. The total solar eclipse left a large part of the Continent’s North Eastern part into sudden darkness.

The eclipse started at the time of dawn and casted its shadow in an area of about 150 kilometers in the Northern Territory of Australia sweeping across the east to the South Pacific after crossing across the northeast tip of the country. This eclipse was partially visible from the eastern half of Australia, East Indonesia, Papua New Guinea, New Zealand and southern parts of Chile and Argentina

Started just after the dawn, the eclipse casted its 150-kilometre shadow in Australia’s Northern Territory, crossed the northeast tip of the country and was swooping east across the South Pacific, where no islands are in its direct path. A partial eclipse was visible from east Indonesia, the eastern half of Australia, New Zealand, Papua New Guinea and southern parts of Chile and Argentina. Totality of the darkness, that happens at the peak of the eclipse lasted just for two minutes in some parts of Australia, where it was visible.

Solar Eclipse 

The Solar Eclipse occur when the moon crosses between the Sun and the Earth blocking the sun completely or partially. This celestial event can occur only on the day of a new moon when, the sun and the moon lies in conjunction to each other when seen from the earth.

A Buddhist statue brought to Germany from Tibet by a Nazi-backed expedition has been confirmed as having an extraterrestrial origin.

Known as the "iron man," the 24-cm high sculpture may represent the god Vaiśravaṇa and was likely created from a piece of the Chinga meteorite that was strewn across the border region between Russia and Mongolia between 10,000 and 20,000 years ago, according to Elmar Buchner of the University of Stuttgart, and his colleagues.

In a paper published in Metoritics & Planetary Science, the team reports their analysis of the iron, nickel, cobalt and trace elements of a sample from the statue, as well as its structure. They found that the geochemistry of the artifact is a match for values known from fragments of the Chinga meteorite. The piece turned into the iron man would be the third largest known from that fall.

Given the extreme hardness of the meteorite – "basically an inappropriate material for producing sculptures" the paper notes – the artist or artists who created it may have known their material was special, the researchers say. Buchner suggests it could have been produced by the 11th century Ben culture but the exact origin and age of the statue – as opposed to the meteorite it is made from – is still unknown. It is thought to have been brought to Germany by a Nazi-backed expedition to Tibet in 1938-39. The swastika symbol on the piece – a version of which was adopted by the Nazi party – may have encouraged the 1938 expedition to take it back with them.

"While the first debris was officially discovered in 1913 by gold prospectors, we believe that this individual meteorite fragment was collected many centuries before," said Buchner in a statement. "The Iron Man statue is the only known illustration of a human figure to be carved into a meteorite."

Although this item may be the only known human figure carved into a rock fallen to earth, other meteorites have also been used by many religions across the world. A 15-ton example in North America called the Willamette meteorite is sacred to some native Americans, while some have suggested that the Black Stone in the Kaaba in Mecca is a meteorite.

Swift J1745-26-------It is the name of newly
discovered black hole toward
the centre of Milky Way galaxy. It
was discovered by NASA's
Swift satellite which detected a
rising tide of high-energy X-rays
from a source toward the center
of our Milky Way galaxy. It is
named after the coordinates of its
position in the sky. The nova is
located a few degrees from the
center of our galaxy toward the constellation Sagittarius
An X-ray nova is a transitory X-ray source that appears suddenly, reaches its
emission peak in a few days and then fades out over a period of months. The
outburst occurs when a torrent of stored gas suddenly rushes toward one of the
most compact objects known, either a neutron star or a black hole.
