Discovery of new human kind of species in China

       Scientists reported on Friday that a gigantic fossilized skull dating back at least 140,000 years has been identified as a new species of ancient human, a discovery that could redefine how — and even where — our species, Homo sapiens, originated.      The skull of an adult guy with a large brain, gigantic brow ridges, deep-set eyes, and a bulbous nose was discovered. After a labourer discovered it at a building site in China, it had been hidden in an abandoned well for 85 years.      The new species was given the name Homo longi, and the nickname "Dragon Man" was given to it after the Dragon River region of northeast China, where the skull was discovered.      According to the researchers, Homo longi, not Neanderthals, was the most closely linked extinct human species to our own. If validated, it would affect how scientists see Homo sapiens' origins, which have been built up over time through fossil finds and ancien...

Hubble Telescope captures something in the space

    A spiral galaxy that hides a supermassive Black Hole in its centre, is imaged by the Hubble Space Telescope.

    Galaxy NGC 3254 is a collection of planets and stars, characterized by their highly active cores, situated at around 118 million light-years.

    With its enormous gravitational power, the black hole at its heart can trap gas, dust, stellar beings and planets in space, photographed with visible and infrared light by Hubble.

NASA's Hubble Telescope

    While one might think that black holes simply devour everything close by with their massive force, the accumulation of material produces enormous amounts of radiation that releases heat and light.

    Scientists compose this image using a light composite from several regions of the spectrum, which partly stops the luminous nucleus from dominating the cosmos in question. Scientists can capture our universe with ultraviolet, visible, and near infra ret light by using Hubble's Wide Field Camera 3 (WFC3).

    This galactic phenomenon is rather unusual yet just ten percent of all galaxies in the known universe are represented in Seyfert galaxies.

    The space telescope of Hubble, however, is not without its own storey. Recently, after the computer crash put it and all its scientific instruments in safety mode, Nasa had to restart the spacecraft.

    The main computer no longer received the "keep-alive" signal, which is a normal "handshake" (a method of establishing a link) between the payload and the spacecraft's main computers. It will be replaced by the James Webb Space Telescope, which Nasa plans to launch into orbit on an Ariane 5 rocket on October 31.

    Scientists will be able to gaze back 150 million to 1 billion years after the beginning of time, something Hubble did not allow them to do previously.
