As SF fans, we are naturally drawn to scientific stories about possible alien life. These two stories appeared on the Astronomy Magazine website in December.\u00a0 The first concerns a signal from Proxima Centauri, the second asks is anyone is looking back at us. \u00a0 –CPL<\/em><\/p>\n

Here\u2019s what we know about the signal from Proxima Centauri<\/h1>\n
The best candidate for an extraterrestrial message in 42 years is probably manmade. But what if it\u2019s not?

An enigmatic radio signal from the direction of Proxima Centauri, the Sun\u2019s nearest stellar neighbor, has set the internet ablaze with rumor and speculation. It could turn out to be the real deal \u2014 a calling card from another civilization. More likely, it\u2019s much ado about nothing.<\/p>\n

The discovery was leaked to the British newspaper The Guardian<\/em>, which reported the story<\/a> December 18. Researchers subsequently granted interviews to Scientific American<\/em> and National Geographic<\/em>. Since then, however, the discovery team has remained tight-lipped about the signal.<\/p>\n

But the information revealed to date is intriguing.<\/strong> READ MORE<\/strong><\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

What would Earth look like to alien astronomers?<\/h1>\n

Ever since 1992, when astronomers first discovered two rocky planets<\/a> orbiting a pulsar in the constellation Virgo, humans have known that other worlds exist beyond our solar system. Today, thanks to the efforts of astronomers and ambitious missions like the now-retired Kepler<\/a>, we know of more than 4,000 confirmed exoplanets.<\/p>\n

But if we can see exoplanets orbiting distant stars, that means extraterrestrial observers should be able to see Earth orbiting the Sun. Our tiny blue marble even could be on an alien astronomer\u2019s list of rocky exoplanets capable of harboring life.<\/p>\n

That\u2019s a speculative scenario, of course, but it\u2019s one astronomers still take seriously. In multiple papers over the years, they\u2019ve identified which exoplanets would be able to spot Earth. And now, with updated information from the European Space Agency\u2019s expansive Gaia catalog of nearby stars, two researchers have provided us with perhaps the best list yet of which alien worlds could have their eyes on us.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
