Toronto, Dec 27 (Canadian-Media): A strange occurrence was witnessed by the scientists around the world for the first time, as studied by observatories, on Aug 17 in which two neutron stars, one hundred and thirty million light-years away, spiraled into each other in a remarkable explosion ranging from gamma ray detectors to radio telescopes, media reports said.
Besides confirming several key astrophysical models, the blast revealed a birthplace of many heavy elements is the first observation of a neutron-star merger revealing its scientific bounty is Science’s 2017 Breakthrough of the Year.
The event of the radiation of spiraling neutron stars before they merged was spotted by detecting the infinitesimal ripples in space itself, called gravitational waves -- Science’s Breakthrough of 2016.
The merger reportedly posed puzzles challenging astrophysicists’ to do more research in such collisions.
Scientists also reportedly hope to see -- through gravitational-wave astronomy -- new and rare types of events, such as mergers of a neutron star and a black hole, or supernova explosions of individual stars in our Milky Way galaxy.
Astrophysicists are reportedly looking forward to see more unpredictable signals.

Toronto, Dec 18 (Canadian-Media): A study published in the journal Earth and Planetary Science Letters challenges the the assumption that Mars formed near Earth from the same building blocks, media reports said.
Mars was reportedly formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current position, before migrating to its present location.
Moreover the two planets have different compositions. Mars contains different, lighter, silicates than Earth, more similar to those found in meteorites.

Researchers from Japan, the United States and the United Kingdom ran simulations to gain insights into the Red Planet's movement within the solar system to explain why the elements and isotopes on Mars differ widely from those on Earth.
In these simulations, the researchers gleaned additional insight into Mars' formation. A small percentage of the simulations suggested that Mars formed much farther from the sun than it is now and that Jupiter's gravitational pull pushed Mars into its current position.
