New Type of Meteorite Identified

Scientists have identified a completely new type of meteorite.
The 8 cm space rock is chemically distinct from any of the 50,000 other such objects held in collections.
Called Österplana 65, it was found in a limestone quarry in Thorsberg, Sweden.
Dating suggests the meteorite's parent body was involved in a huge collision in the asteroid belt between Mars and Jupiter some 470 million years ago.

New Planet that Orbits Two Suns

NASA has discovered a new planet that is also the largest planet that orbits two suns.
As per scientists, the planet is too unobtrusive to be seen by the naked eye, but falls in the direction of the constellation Cygnus.
As per NASA, Kepler-1647 is 3,700 light years away and approximately 4.4 billion years old, roughly the same age as Earth. The stars are similar to the sun, with one slightly larger than our home star and the other slightly smaller. The planet has a mass and radius nearly identical to that of Jupiter, making it the largest transiting circumbinary planet ever found.

Names for New Chemical Elements

Names have now been proposed for the four new chemical elements added to the periodic table in January.
They are nihonium (with the symbol Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og).
Until now, the quartet have been referred to simply by the number of protons in each atom - 113, 115, 117 and 118, respectively.
The names must go out to consultation for five months, but if there are no objections their confirmation should be a formality.

Hydrogen Detected in Distant Galaxy

For the first time, an international team of scientists has detected a faint signal emitted by hydrogen gas in a galaxy more than five billion light years away.
The team observed radio emission from hydrogen in a distant galaxy and found that it would have contained billions of young, massive stars surrounded by clouds of hydrogen gas.
