Is there anybody out there?

Is there anybody out there?

That search is accelerating. As Dr Siemion told this year's meeting of the American Association for the Advancement of Science ( AAAS ), in Seattle, better telescopes, faster computers, the discovery of thousands of planets circling stars other than the sun, and an influx of money and scientific talent are transforming the field. What was once a fringe activity has now become mainstream.

They will brighten further with the launch, in 2021, of the James Webb Space Telescope and the opening of new observatories on the ground, such as the Extremely Large Telescope ( ELT ) in Chile. These will be able to repeat, for some nearby exoplanets, the first of Sagan's experiments with Galileo —the search for biosignatures. But, even if they find them, exciting as that would be, it would say nothing about the crucial final letter in SETI , the "I" for intelligence.

What can the coronavirus outbreak teach us about bringing Mars samples back to Earth? | Space

But me being me, my mind went straight to Mars. I have long been aware of science fiction's vision of Earth receiving space souvenirs that carry organisms that might be dangerous to Earth's fragile biosphere — that's me, and you, too! Such arrivals could be accidental, or they could be purposeful.

Meanwhile, President Donald Trump's budget request for NASA supports the development of the Mars sample return mission , a robotic program that would haul back the goods from the Red Planet.

SETI search of interstellar Comet Borisov finds no sign of alien 'technosignatures' | Space

Our solar system's second known interstellar visitor appears to be keeping quiet, just like the first.

The Breakthrough Listen SETI (search for extraterrestrial intelligence) project has scanned the interstellar Comet Borisov for "technosignatures" but come up empty so far, scientists announced today (Feb. 14). 

Breakthrough Listen also encountered radio silence during an earlier investigation of the mysterious 'Oumuamua , the first confirmed interstellar object ever spotted in our solar system. The null results may be disappointing to alien enthusiasts out there, but they're valuable all the same, project team members said.

No Signs of Alien Tech Found by SETI Scans of Our Interstellar Visitor 2I/Borisov

A mysterious comet identified last year as only the second-ever known interstellar object in our Solar System inevitably prompted some big scientific questions. Chief among them: what, if anything, can it tell us about the hypothesised existence of extraterrestrial intelligence out there in space?

The news, revealed by SETI (search for extraterrestrial intelligence) scientists at the annual meeting of the American Association for the Advancement of Science (AAAS) this month, highlights the almost overwhelming amount of unknowns and variables that challenge SETI researchers.

While you're here, how about this:

Scientists Find The First-Ever Animal That Doesn't Need Oxygen to Survive

That symbiotic relationship resulted in the two organisms evolving together, and eventually those bacteria ensconced within became organelles called mitochondria. Every cell in your body except red blood cells has large numbers of mitochondria, and these are essential for the respiration process.

They break down oxygen to produce a molecule called adenosine triphosphate , which multicellular organisms use to power cellular processes.

We know there are adaptations that allow some organisms to thrive in low-oxygen, or hypoxic, conditions. Some single-celled organisms have evolved mitochondria-related organelles for anaerobic metabolism; but the possibility of exclusively anaerobic multicellular organisms has been the subject of some scientific debate.

Kobe Bryant's on-court heroics provide only a glimpse of The Legend of the Black Mamba - KTVZ

The love was on full display Monday as fans and celebrities — an A-list cast by even Hollywood standards — packed the Staples Center to remember one of their own .

Astronomers say when the biggest stars die they become supernovae, shining brighter than the Milky Way and capable of spurring the formation of other stars.

Bryant was one such supernova. “A 6-6 guard from Lower Merion High School” in Pennsylvania, he joined the NBA in 1996 as a child. Over 20 seasons, he won five championship rings and forged an extraterrestrial reputation as a suffocating defender and one of the greatest scorers to ever bounce a Spalding.

Seattle's Moisture Festival offers up a vaudeville-meets-21st century vibe

There are festivals devoted to bacon and beer, wine varietals, racing bedsteads and visiting extraterrestrials. So why are we surprised by a festival niche inspired by weather? From fog fairs and wind shindigs to snowglobe festivities, name a weather phenomenon and there’s probably a festival dedicated to it.

There’s the San Ramon’s Art and Wind Festival, which is held each May and offers kite-making workshops, kite-flying demos and a hot air balloon. Pacifica goes all out each September with its Pacific Coast Fog Fest in September.
