In our hunt for Earth-like planets and extraterrestrial life, we’ve found thousands of exoplanets orbiting stars other than our sun. The caveat is that most of these planets have been detected using indirect methods. Similar to how a person can’t look at anything too close to the sun, current telescopes can’t observe potential Earth-like planets because they are too close to the stars they orbit, which are about 10 billion times brighter than the planets that surround them.
A possible solution might be to create an artificial solar eclipse with two precisely positioned spacecraft, according to Simone D’Amico, assistant professor of aeronautics and astronautics at Stanford and director of the Space Rendezvous Laboratory. One craft – known as a starshade – would position itself like the moon in a solar eclipse, blocking out the light of a distant star, so a second spacecraft with a telescope could view the nearby exoplanets from within the shadow cast by the starshade.
“With indirect measurements, you can detect objects near a star and figure out their orbit period and distance from the star,” said D’Amico, whose lab is working on this eclipsing system. “This is all important information, but with direct observation you could characterize the chemical composition of the planet and potentially observe signs of biological activity – life.”

Last week, a U.S. House Committee gave its approval for the SELF DRIVE Act, a bill that introduces breakthrough legislation in favor of autonomous vehicles. The bill could pass Congress before the end of 2017, ushering in a new era in self-driving tech.
In a report published in 2016, the White House estimated that nearly 3.1 million drivers working today could have their jobs automated by autonomous vehicles.

One of the greatest fears of the world’s space is a real-life Andromeda Strain, the chilling movie about a US research satellite carrying a deadly extraterrestrial microscopic organism that crashes into a small town in Arizona. A group of top scientists are hurriedly assembled in a bid to identify and contain the lethal stowaway.

Is a CG short about space exploration and the quest of finding traces of extraterrestrial forms of life. Flying over spectacular desert planet. seeing strangely familiar ancient civilizations remains and experiencing a first contact with the existence of unknown living things.
Big thanks to Robot Koch and Savannah Jo Lack for composing and recording this beautiful soundtrack.

This brisk cadence of celestial surprises might make it seem that we’re on the cusp of proving the existence of extraterrestrials. But just because the crow’s nest announces clouds on the horizon doesn’t mean you’re close to land.
These three claims purporting to show the existence of aliens haven’t panned out. But what happens if some future claim does? What preparations are in place to deal with the discovery of a radio signal or a laser flash that would prove beyond doubt that we have cosmic compeers? Does the government have a plan? Does anyone?
A lot of people think there is a plan. A secret one. A recent survey indicated that 55 percent of the population figure that the discovery of extraterrestrials would be squelched — deep-sixed to prevent widespread panic. Only 19 percent believe the feds would fess up to E.T.’s existence.

US government scientists work hard to protect the public.
Some study infectious diseases and effective treatments. Others ensure that drugs, food, vehicles, or consumer products live up to their claims and don’t harm anyone.
But the concerns at NASA’s headquarters are, quite literally, extraterrestrial — which is why the space agency now has a job opening for “planetary protection officer.”

Advanced technological civilizations looking for efficient communication from one end of a galaxy to another would best be served by tapping into a network of transiting extrasolar earths. That is, extrasolar earths capable of being observed transiting across the face of their parent stars. Or so says an exoplanet researcher in the U.K.
Kepler-type space observatories out looking for transits of extrasolar earths, could also look for the telltale signatures of optical lasers or even alien macro-engineering projects that might be manipulated to signal another civilization.
