Just few days ago astronomers claimed to have to discover a Pulsar, PSR J0540-6919, which lies outside the Tarantula Nebula in the Large Magellanic Cloud nearly 163,000 light-years away. Pulsars are neutron stars, remnants from supernova detonations. The swiftly spinning magnetic field of the tremendously dense star core emits rays of radio waves, visible light, X-rays and gamma rays. The important thing about J0540 was that it spins just under 20 times per second, according to data acquired by the Fermi probe. Another rare characteristic of the J0540 is its age: The pulsar is approximately 1,700 years old, whereas most of the other 2,500 known pulsars are calculated to be ranged in age between 10,000 and hundreds of millions of years.

According to the observations, GJ 1132b is just 1.2 times the mass of Earth, and seems to be a rocky world with habitable atmosphere. Writing in the journal Nature, researchers at the Massachusetts Institute of Technology have labelled it the “closest Earth-sized exoplanet yet discovered.”
Well this is not it yet, another astounding discovery this week came from a terrestrial telescope located high up on Hawaii’s dormant volcano Mauna Kea. A group of astronomers working at the Subaru telescope spotted an icy dwarf planet orbiting on the external edge of our solar system. An icy body 500-1000 km wide, the V774104 is 9.6 billion miles (15.4 billion kilometers) from the Sun. According to the astronomers this is one of the most important planet discovered so far.
Scott Sheppard from the Carnegie Institution for Science in Washington, DC, who declared the discovery at a meeting of the American Astronomical Society, said "We can't explain these objects' orbits from what we know about the solar system. The findings may need astronomers to re-examine the current model of the solar system’s origins”
