Was the Ordovician Extinction, 450 mya, caused by a hypernova 100 thousand light-years away?

Deadly gamma-rays from an exploding star might have caused a mass extinction

A 2012 study on ancient cedar trees in Japan suggested that our planet was hit by a massive gamma ray burst in the century CE. Now, a new study suggests that the cause of this burst was two black holes or two neutron stars merging within our galaxy.

Galaxies CollideCredit: X-ray: NASA/CXC/SAO/E. Nardini et al; Optical: NASA/STScI Monday, May 6, 2013: An enormous cloud of hot gas envelopes two large, colliding galaxies. The system called NGC 6240, called a halo, contains two merging spiral galaxies, each similar in size to our own Milky Way. The two galaxies both contain a supermassive black hole at their centers, which spiral toward each other.

NGC 3190 is a spiral galaxy with tightly wound arms and lying in the constellation Leo. It was discovered by William Herschel in NGC 3190 is member of Hickson 44 galaxy group, estimated at around 80 million light years and consisting of four

NGC 7293: The Helix Nebula  Image Credit & Copyright: Ed Henry (Hay Creek Observatory)     Explanation: A mere seven hundred light years from Earth, in the constellation Aquarius, a sun-like star is dying. Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. A total of 10 hours of exposure time have gone in to creating this remarkably deep view of the nebula...

This is the Helix Nebula, often referred to as the eye of God. It was produced by a sunlike star dying over a span of thousands of years

Bu gün Hindistanın en büyük bayramlarından biri olan Divali. Bu bayram, ışık festivali olarak da bilinir. Geceleri yakılan sayısız yağ kandili Rama’nın sürgünden evine dönüşünü canlandırır. Bu festival, Bombay’da Laksmi’ye ve Kalküta’da Kali’ye adanmıştır.  Tamamı beş gün süren bu bayramın birinci günü yeni iş yılı döneminin başlangıcıdır.
