Stephen Hawking's effort to find intelligent life just got a huge boost

E. T. phone home?

The Breakthrough Listen project, an effort to search even deeper for extraterrestrial life, was formed by entrepreneur Yuri Milner and astrophysicist Stephen Hawking, who died in March. The project is surveying both the Milky Way galaxy and nearby galaxies using the Parkes Telescope in New South Wales, Australia.

"With these new capabilities we are scanning our galaxy in unprecedented detail," Parkes project scientist Danny Price of the University of California, Berkeley, said in a statement." By trawling through these huge datasets for signatures of technological civilizations, we hope to uncover evidence that our planet, among the hundreds of billions in our galaxy, is not the only where intelligent life has arisen."

The latest addition to the telescope that makes this search effort faster and deeper is the new multibeam receiver. It uses 13 beams to observe much larger pieces of the sky than previously possible.

That addition has pushed the data arriving from the telescope and receivers to 130 gigabits per second. Wow.

The multibeam receiver also allows much quicker sorting between man-made signals or interference from Earth-bound devices and those on another planet. 

Over the next 60 days, the Parkes telescope will spend 1,500 hours listening for extraterrestrial signals. 

One type of signal that's particularly fascinating to scientists is when they come across Fast Radio Bursts, or FRBs. These are quick, vibrant radio signal bursts of unknown origin, and the closest was observed 1.6 billion light-years away. They're not necessarily an indicator of any alien intelligence, but they do originate from sources that have extremely powerful magnetic fields.

Is this why time speeds up as we age?

We take fewer mental pictures per second.

Mind & Brain
  • Recent memories run in our brains like sped-up old movies.
  • In childhood, we capture images in our memory much more quickly.
  • The complexities of grownup neural pathways are no match for the direct routes of young brains.

New alternative to Trump's wall would create jobs, renewable energy, and increase border security

A consortium of scientists and engineers have proposed that the U.S. and Mexico build a series of guarded solar, wind, natural gas and desalination facilities along the entirety of the border.

Politics & Current Affairs
  • The proposal was recently presented to several U.S. members of Congress.
  • The plan still calls for border security, considering all of the facilities along the border would be guarded and connected by physical barriers.
  • It's undoubtedly an expensive and complicated proposal, but the team argues that border regions are ideal spots for wind and solar energy, and that they could use the jobs and fresh water the energy park would create.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
