Paul Scott Anderson has had a passion for space exploration that began when he was a child when he watched Carl Sagan’s Cosmos. While in school he was known for his passion for space exploration and astronomy. He started his blog The Meridiani Journal in 2005, which was a chronicle of planetary exploration. In 2015, the blog was renamed as Planetaria. While interested in all aspects of space exploration, his primary passion is planetary science. In 2011, he started writing about space on a freelance basis, and now currently writes for AmericaSpace and Futurism (part of Vocal). He has also written for Universe Today and SpaceFlight Insider, and has also been published in The Mars Quarterly and has done supplementary writing for the well-known iOS app Exoplanet for iPhone and iPad.
A new research study suggests that K-type dwarf stars (smaller and cooler than our sun) are the best place to search for alien life. These stars are not too hot, not too cool, and not too violent for life to evolve.
Grains of stardust – particles left behind by star explosions – in an Australian meteorite are now the oldest known material on Earth. A new study suggests this stardust came to be long before our sun ever existed.
In recent years, astronomers have pondered the search for biosignatures, or signs of life, in the atmospheres of distant exoplanets. Will the James Webb Space Telescope – due to launch in 2021 – be able to detect them? A new technique says yes.
The building blocks of life as we know it require chemical reactions involving phosphorus. But phosphorus is scarce on Earth. Where did enough of it come from to fuel life’s start? Carbonate-rich lakes, like Mono Lake in California, might hold a clue.
We’ve known for some time that Venus has vast lava plains, fields of small lava domes, and large shield volcanoes. But does it still have active volcanoes? A new study involving lava flows on Venus suggests that, yes, it does.
Using a revolutionary X-ray telescope aboard the International Space Station, scientists have finally created the 1st pulsar surface “map.” It shows odd hot spots and suggests that pulsar magnetic fields are more complicated than anyone had assumed.
