A 10-year international effort to reveal our planet’s secrets found that the ‘deep biosphere’ amounts to 15 to 23 billion tonnes of life – far more than previously believed.
Scientists with the Deep Carbon Observatory drilled 1.5 miles into the seabed, and sampled microbes from mines and boreholes up to three miles deep.

Two types of microbes – bacteria and archaea – dominate Deep Earth.
This so-called microbial “dark matter” dramatically expands our perspective on the tree of life. Sientists now believe that about 70% of Earth’s bacteria and archaea live in the subsurface
Deep microbes are often very different from their surface cousins, with life cycles on near-geologic timescales, dining in some cases on nothing more than energy from rocks.
The findings have led some experts to question whether life actually began deep beneath the surface, either within the crust, near hydrothermal vents, or in subduction zones, then migrated upwards towards the sun.
Fumio Inagaki, Japan Agency for Marine-Earth Science and Technology says, ‘Even in dark and energetically challenging conditions, intraterrestrial ecosystems have uniquely evolved and persisted over millions of years.
‘Expanding our knowledge of deep life will inspire new insights into planetary habitability, leading us to understand why life emerged on our planet and whether life persists in the Martian subsurface and other celestial bodies.’
Besides our usual suggestions of new TV shows, movies and games to watch this week, we’ve got a 50-year-old video that you really should see. Also, the second human-made object has entered interstellar space, plus, there’s a confusing deal between Samsung China and “Supreme.”
Innovation usually happens in slow, measured steps over many years, but a demo in 1968 transformed the world of personal computers in just 90 minutes. In a presentation dubbed “the mother of all demos,” Douglas Engelbart showed off technology that would lead directly to Apple’s Macintosh, the internet, Windows, Google Docs, the computer mouse and much, much more. The most remarkable part was that it happened 50 years ago, in 1968, when microchips were just a gleam in scientists’ eyes.
NASA’s Voyager 2 spacecraft has exited the heliosphere — the plasma bubble created by the sun that encompasses most of our solar system — and entered interstellar space, making it the second human-made object to do so. Voyager 1 was the first to do it, but this spacecraft still has a working Plasma Science Experiment, used to measure solar-wind particle flow until the amount dropped to nothing at all. Both spacecraft are still technically within the solar system, however. And they will be until they exit the Oort Cloud, a large collection of distant objects that are still affected by the sun’s gravity.

In an interview with CBS program 60 Minutes, Musk declared that he’s only abiding by the SEC because he “respects the justice system.” He also said he handpicked Robyn Denholm as Tesla’s new board chair, and that aside from not wanting to be chairman again, he would prefer “to have no titles at all.”
Fyre Festival was billed as “the cultural experience of the decade,” but as we all know, it actually turned out to be a massive disaster and far from the luxurious, celebrity-filled event it was advertised to be. A new documentary, Fyre, gives viewers a look into the festival as described the organizers themselves.
Keep your eyes glued to the sky because 2018’s brightest comet is about to make an appearance.
According to EarthSky, Comet 46P/Wirtanen is expected to pass closest to the sun on December 12 and closest to Earth on December 16, when it will be 12-million km away.
Kat Kelly, astronomer at Vancouver’s HR McMillan Space Centre, explains that 46/P will appear as a greenish-blue glowing ball in the sky.
While comets are known to have a tail of light that follows them, 46P will not.
“We are unlikely to see a tail,” Kelly told Daily Hive. “Just the main snowball part.”
She says that comets are essentially “dirty snowballs” in the sky. “They are kind of like ice and gravel packed together with small pieces of dust and rock.”
Space enthusiasts around the world have already spotted the comet using high-powered telescopes.

Images show a turquoise glowing ball in the night sky with a faint tail, trailing behind.
Brett Gladman, professor at the Department of Physics and Astronomy at the University of British Columbia, says that 46P is an older comet — first spotted in the 1940s — that reaches Jupiter on its 5-year orbit cycle.
“It has gone close to the sun and burned off a lot of its tail,” Gladman told Daily Hive.
Those wanting to see 46P should head out to a very dark outdoor area on the evening of December 15 or 16, which is when the comet will be closest to earth.
Kelly says the best time for viewing will be between 12 and 2 am and the comet will be south facing.
“If people know the Orion Constellation, [46P] is kind of at the top right,” she said.
But Gladman warns not to get “all excited” about the phenomenon because the comet will be difficult to see. “It will be faint and diffuse,” he said.
If you’re a city dweller, it’s best to head out to the darkest spot you can find, and look up for turquoise glow. And if you don’t see 46P this time around, it will be back in another 5 years.
