First Head Transplant

An Italian surgeon Dr. Sergio Canavero has claimed that he has succesfully carried out the first head transplant on monkey.
He further plans to attempt the controversial procedure on a human being by the end of 2017.
He says that the procedure will be ready before the end of 2017 and could eventually become a way of treating complete paralysis.

Scientists Successfully Revive Frozen Animal

Scientists have succeeded in bringing a frozen animal back to life after 30 years, it has been reported.
Scientists at Japan's National Institute of Polar Research have succeeded in reviving the 'tardigrade' animal which they had collected in Antartica.
The creatures, which are known as 'water bears' or 'moss piglets' are miniscule, water dwelling "extremophiles" measuring less than 1mm in length and dwelling in extreme and hostile conditions.

A Galactic Mega-merger

Astronomers have viewed a galactic mega-merger, a product of a collision between two good-sized galaxies, which is slowly evolving to become a giant elliptical galaxy.
As per researchers, this type of galaxy has grown more and more common as the universe has evolved, with initially small galaxies merging and progressively building up into larger galactic structures over time.
NGC 3597 is located approximately 150 million light-years away in the constellation of Crater (The Cup).

NASA Programme to Protect Earth

NASA has started a new programme called the Planetary Defence Coordination Office (PDCO), which will coordinate the space agency's efforts to detect and track near-Earth objects (NEOs).
Most asteroids and comets in our solar system are small and stay safely in orbit within the asteroid belt between Mars and Jupiter.
But some are large enough to do damage and are in orbits that bring them close enough to our planet.
In order to protect the Earth from these potential hazards, the PDCO has two main roles. First, it is responsible for finding and characterising these NEOs. Second, the PDCO is in charge of coordinating emergency efforts with other agencies and governments if a large NEO was predicted to impact the Earth.

Universe's Most Luminous Galaxy

New observations have revealed that an obscured quasar 12.4 billion light-years away which is known as the most luminous galaxy in the Universe is so violently turbulent, that it may eventually cast off its entire supply of star-forming gas.
After the observation the researchers found that the galaxy is so chaotic that it is ripping itself apart.
Evidence strongly suggests that this galaxy is an obscured quasar, a very distant galaxy with a voraciously feeding super massive black hole at its center that is completely obscured behind a thick blanket of dust.

NASA Awards Space Station Cargo Contracts

US space agency NASA has awarded the second round of commercial contracts to resupply the International Space Station to the following three private spaceflight companies Orbital ATK, Sierra Nevada and SpaceX.
Each of these companies will get at least six flights to deliver cargo to the space station, which will begin in late 2019 and extend through 2024.
Orbital ATK of Virginia and SpaceX of California, the winners of the first round of NASA's Commercial Resupply Services contracts, have already used their own space capsules to send supplies several times to the orbiting lab about 400 kilometers above Earth.
The only new face is Colorado-based Sierra Nevada.

The Most Luminous Supernova

A team of astronomers has discovered the most luminous supernova ever observed. It is called ASAS-SN-15lh.
Supernovae are violent stellar explosions and some of the brightest objects in the universe.
The newly found super-luminous supernova was discovered by the All Sky Automated Survey for SuperNovae team. The only all-sky variability survey in existence, it is capable of finding normal supernovae out to about 350 million light years from earth.
