Astronomers found a gas in Venus' clouds that could signal alien life

An image of Venus. NASA Goddard Spaceflight Center Venus' carbon-dioxide-rich atmosphere and high temperatures make the planet's surface inhospitable to life. But new research suggests the clouds surrounding Venus could harbor microbial life. A new study found traces of phosphine — a gas typically produced by anaerobic microbes on Earth — in the upper reaches of Venus' clouds. The researchers suggest the phosphine's origin "could be unknown photochemistry or geochemistry, or possibly life....

A Physicist Examines the Scientific Accuracy of Physics Shown in Major Movies: Batman, Gravity, Contact, Interstellar, Star Trek & More

Ever had a friend who cannot bring themselves suspend disbelief? It’s not a moral failing, but it can be a tedious quality in situations like, say, the movies, or the cinema, or whatever you call it when you’ve paid your day’s wages for a giant tub of carcinogenic popcorn and a three-hour distraction. (These days, maybe, an overpriced streaming new release and Grubhub.) Who doesn’t love a big-screen science fiction epic—science be damned? Who wants to listen to the seatmate who mutters "...

When Astronomer Johannes Kepler Wrote the First Work of Science Fiction, The Dream (1609)

The point at which we date the birth of any genre is apt to shift depending on how we define it. When did science fiction begin? Many cite early masters of the form like Jules Verne and H.G. Wells as its progenitors. Others reach back to Mary Shelley’s 1818 Frankenstein as the genesis of the form. Some few know The Blazing World, a 1666 work of fiction by Margaret Cavendish, Duchess of Newcastle, who called her book a “hermaphroditic text.” According to the judgment of such experts as Is...

Q&A: ‘Cosmos’ author Ann Druyan muses about possible worlds — and what Carl Sagan would do

How many dimensions does the cosmos have? If we're talking about string theory, it could be 10, or 11, or 26 dimensions. But if we're talking about "Cosmos," the TV series made famous by the late astronomer Carl Sagan 40 years ago, there are now three dimensions. It all started with the original "Cosmos: A Personal Voyage," which brought cosmic topics such as stellar evolution and extraterrestrial life to prime-time TV in 1980. Eighteen years after Sagan's death in Seattle, the show ...

Carl Sagan's Pale Blue Dot image is 30 years old today

Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes' cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was not to be missed. From my liner notes to the Voyager Golden Record vinyl box set: Astronomer and educator Carl Sagan, a member of the Voyager Imaging Team,...

How the Sagan standard can help you make better decisions

Carl Sagan famously shared the aphorism "Extraordinary Claims Require Extraordinary Evidence."This approach can help us fight off fake information.Scientific thinkers in centuries before Carl Sagan also expressed similar sentiment. None Is there an omnipotent all-knowing entity, otherwise known as "God", ruling our daily affairs and caring enough to judge our behaviors on an individual basis? Or is our life ruled by an invisible supercomputer that pre-ordains most of our actions, ensuring an i...

Neil deDrasse Tyson Teaches Scientific Thinking and Communication in a New Online Course

One doesn't normally get into astrophysics for the fame. But sometimes one gets famous anyway, as has astrophysicist Neil DeGrasse Tyson, Director of the Hayden Planetarium at the Rose Center for Earth and Space. But that title doesn't even hint at the scope of his public-facing ventures, from the columns he's written in magazines like Natural History and StarDate to his hosting of television shows like NOVA and the sequel to Carl Sagan's Cosmos to his podcast StarTalk and his high-profi...

Neil deGrasse Tyson: Want to prove aliens exist? Do this.

Are UFOs actually alien spacecraft visiting Earth? They might be, says Neil deGrasse Tyson, but if you want to make that claim you better bring the evidence to support it.Eyewitness testimony is the lowest form of evidence. To measure what is true or not true in the world, we require data -- and when it comes to alien appearances, it's as astronomer Carl Sagan said: "Extraordinary claims require extraordinary evidence."So what can you do to prove your alien abduction story? Take selfies, live-st...

How the first picture of a black hole captures a big 2019 mood

For decades, pictures from space have forced humanity to reckon with our own cosmically small insignificance. But they have nothing on today's monumental first in space photography.  The Event Horizon Telescope captured a phenomenon so mysterious, so literally awesome that, for many years, scientists believed it would be impossible to depict: a black hole. EHT's international group of astronomers revealed "a bright ring formed as light bends in the intense gravity around a black hole t...

Laser "porch light" could be a beacon for ETs

A feasibility study in the Astrophysical Journal explains how a powerful laser on an Earth mountaintop, focused through a huge telescope, could shine a light of infrared radiation that would be detectable up to 20,000 light years away. While some scientists are concerned about alerting extraterrestrials to our presence, I agree with what something said to me by Ann Druyan -- co-writer of Cosmos and many other works with her husband Carl Sagan -- when we were working on the Voyager Golden Record:...

Laughing Gas May Have Helped Warm Early Earth and Given Breath to Life

Laughing gas and the mystery of Carl Sagan's Faint Young Sun Paradox: When the sun shone dimmer an eon ago, Earth remained warm in spite of it likely thanks to a mix of greenhouse gases. Biogeochemists have now shown how N20, known today for its use as a dental anesthetic, may have made it into the mix.
