Alien Sign found On Earth?

àlien life mars extraterrestial found science weird

Researchers from university, New York, believe uncountable years of evolution on Earth will facilitate notice life on alien worlds.

By wanting back at over five hundred million years of the Earth’s plant-life history, we tend to might higher perceive distant livable  exoplanets.

The emergence of flora on Earth was an important part within the processes that reworked the rocky planet into one wherever life may thrive.

The same processes on exoplanets might be equally chargeable for harboring and sustaining alien life.

The key to the current is that the alleged “vegetation red edge” – a method by that a inexperienced planet reflects high amounts of infrared emission.

Lisa Kaltenegger, Associate in Nursing uranologist United Nations agency co-authored a study on the subject, aforementioned Earth’s history of vegetation is that the best example of this.

The professional said: “Looking at however life altered Earth’s biosignatures over time helps United States of America decipher that planets square measure possibly to indicate the strongest signs of life, ultimately giving United States of America the most effective possibilities of with success pinpointing life, if it's there.”

Geological records geological dating back over five hundred million years show a forceful amendment in Earth’s surface conditions once the primary forests emerged.
Over time, immense fields of ice gave thanks to thick forests covering the land, serving to replicate a lot of infrared emission.

The earliest records of Earth’s history purpose towards mossy rocks and week plants inhabiting the world.

Compared to trees, it's tougher for astronomers to notice signs of such vegetation.

But finding sturdy proof of tree-like life on livable  exoplanets might be an honest indicator of the planet’s age.

Stephen Hawking's Final Book gives brief Answers to Big Questions

Stephen Hawking's final work was launched by his children on Monday which discuss issues from Existence of God to Time Travel and other big questions. His children completed his final book after he died last year.

Stephen started his book last year to answer the common question which he encountered many times from public. The title of the book is ''Brief Answers to Big Questions''.

His daughter, Lucy Hawking, said he was regularly asked for such question and this book contains his clear and most authentic answers. We all wish he was here to see it published, she added.

What are these big questions and what did he write answers to them?

Is there a God?How Did it All Began?What is inside a black hole?Can we predict the future?Is Time Travel possible?Will we survive on Earth?Is there any other intelligent life in Universe?Should we colonize space?How do we shape the future?Multiple challenges Stephen Hawking says the simplest explanation is that God does not exist and…

Human flights to ISS will begin in 2019

NASA has confirmed that manned space flight will be carried by SpaceX and Boeing in the mid of 2019.SpaceX rocket for ISS will depart in June 2019 while Boeing spacecraft will go in August 2019.
It will be the first US mission since the retirement of the shuttle in 2011.NASA's astronauts are currently using Russian made Soyuz spacecraft and its contract will end in June 2019.NASA said on 4th of the October that it will give monthly updates 

Phil McAlister who is the director of commercial flights in NASA said in Blog that 

New Updates schedule is better but launch schedule may be uncertainHe also said these are new spacecraft and lot of engineering work has to be done before take off.

Back in 2014 both the SpaceX and Boeing received $6.8bn from NASA to build spacecraft that will take humans to ISS.

Boeing has said they will be ready for Orbital Flight Test in March 2019.
The Success of this manned space shuttle will be a great achievement of the commercial space industry, and NASA will …

The Mystery of ISS leak

A leak was found on Russian made Soyuz MS-09 Spacecraft on International Space Station by Astronauts which caused loss of oxygen on 30 Aug. First, it was thought it was due to a Meteorite hit to ISS but Russia rejected saying this leak was man-made.

Recently NASA's head Jim Bridenstine said that investigations will be done soon to determine the cause of leak to ISS which caused a brief deficiency of Oxygen to astronauts there. He also rejected the rumor that the U.S is trying to pull back Russia from ISS.

He further added;
"I strongly believe we're going to get the right answer to what caused the hole on the International Space Station and that together we'll be able to continue our strong collaboration,What we've got to do is we've got to very dispassionately allow the investigation to go forward without speculation, without rumor, without innuendo, without conspiracy." Russian agency said they will not accept any mythical reason until solid proof given…
