The science refresher you need before diving into Netflix's hit sci-fi series '3 Body Problem'
Netflix's "3 Body Problem" makes a lot of physics references. Two experts help explain some scientific concepts to help you understand the show.
SETI
Scientists had a groundbreaking conversation with a humpback whale in her own language and it could help humans chat with aliens one day
A groundbreaking encounter between scientists and a humpback whale named Twain could shape our first conversation with an intelligent alien race.
The world's top alien hunters explain why a Harvard physicist's discovery of 'alien' tech is likely a false alarm
Scientists from top alien-hunting organizations SETI and METI don't think Harvard physicist, Avi Loeb, found evidence of alien intelligence.
The alien-hunting team at SETI has a new test for humanity to decipher messages sent from an alien race
SETI hasn't detected a real message from aliens so it decided to simulate one and see how people reacted and how long it would take to decode.
Smart aliens might live within 33,000 light-years of Earth. A new study explains why we haven't found them yet.
The universe has so many galaxies, stars, planets, and moons that many scientists believe an intelligent extraterrestrial race should exist within detectable range of Earth. Humans have yet to detect such alien signals, but a new study suggests we've barely scratched the surface in our search.
An alien hunter explains why extraterrestrial visitors are unlikely — despite the US government's UFO evidence
Astronomer Seth Shostak is skeptical about alien visitation: "It is a little odd that aliens would come hundreds and hundreds of light-years to do nothing."
Astronomers are listening for alien signals from a weird object that's flying through the solar system
Using the Green Bank radio telescope in West Virginia, astronomers are targeting the oddly shaped 'Oumuamua asteroid, an object from beyond the solar system.
Astronomers have solved the mystery of 'strange signals' that appeared to come from a star 11 light-years away
Radio signals picked up by Arecibo, the famous alien-hunting telescope in Puerto Rico, are us — not them.
Astronomers have detected 'strange signals' that may come from a star 11 light-years away
It's very unlikely that intelligent alien life is responsible for the signals coming from Ross 128, a red dwarf star, but the possibility can't be ruled out.
A Russian tycoon's $100 million effort to listen for aliens has published its first results
Breakthrough Listen's radio telescopes heard millions of possible signals, but only 11 rose to significance.
Stephen Hawking warned us about contacting aliens, but this astronomer says it's 'too late'
Stephen Hawking thinks trying to contact alien life is dangerous, but a top astronomer says it's too late.
6 new mysterious radio signals have been detected coming from the same region outside our galaxy
They only last milliseconds, but in that short period of time, they generate as much energy as the Sun in an entire day
The shields that we'd build to protect ourselves from an exploding star could help us find alien civilizations
Not too far from now we might be able to construct the sort of barrier that could withstand a blast of cosmic-ray radiation that would be caused by a supernova.

Not too far from now we might be able to construct the sort of barrier that could withstand a blast of cosmic-ray radiation that would be caused by a supernova.
234 stars seem to be emitting alien-like signals
Analyzing the spectra of 2.5 million stars, astronomers have found 234 that produced the same strange signal — pulses of light at constant time intervals.
Stephen Hawking's alien-hunting project is investigating strange signals from 234 stars
Astronomers have been analyzing light signals from 2.5 million stars and have detected strange 'strobe-like' bursts coming from not one, but 234 stars.
Stephen Hawking warned us about contacting aliens, but this astronomer says it's 'too late'
Stephen Hawking thinks trying to contact alien life is dangerous, but a top astronomer says it's too late.
The government stopped funding the search for aliens — and this astronomer says that’s a big problem
NASA no longer funds the search for intelligent alien life, and one astronomer says that's a big setback.
Stephen Hawking warned us about contacting aliens, but this astronomer says it's 'too late'
Stephen Hawking thinks trying to contact alien life is dangerous, but a top astronomer says it's too late.
That 'interesting' and possibly alien radio signal probably came from our own planet
Russian astronomers have suggested a possibly alien signal was coming from the star HD 164595, but the Russian Academy of Science says it came from Earth.
