  2. The Wow signal lasted just 72 seconds and was 'unusual' and has yet to be traced This led many to theorise the signal came from an intelligent alien civilisation Amateur astronomer Alberto Caballero has been searching the Gaia catalogue This catalogue contains details on 1.3 billion stars from around the universe He found a Sun like star in the region of space the signal is known to originate Source: https://www.dailymail.co.uk/sciencetech/article-8985997/Amateur-astronomer-traces-possible-source-notorious-WOW-signal.html Ps.: I'm the author of the paper, feel
  3. In this paper it is presented the concept and design of a new type of spacecraft that could be used to make the first manned interstellar travel. Solar one would integrate three near-term technologies, namely: compact nuclear fusion reactors, extremely large light sails, and high-energy laser arrays. A system of lenses or mirrors to propel the sail with sunlight is suggested as an alternative to laser propulsion. With a mile-long light sail, Solar One could reach an average of 22% the speed of light, arriving to the closest potentially habitable exoplanet in less than 19 years with the help of
  4. The Big Ear Radio Telescope in Delaware, Ohio, was disassembled in 1998 having operated for over 30 years. It was replaced by a golf course. Big Ear was never the world’s biggest radio telescope, nor its most sensitive. But Big Ear nevertheless made one of the most famous observations in the history of astronomy, one that till this day has never been explained. Throughout the 1970s, Big Ear searched for signals from extraterrestrial civilizations. And on Aug. 15, 1977, it found one — a strong, intermittent signal lasting for 72 seconds, that stood out from the background noise like a sear

  6. Hi everybody, My name is Alberto Caballero. I have been recently coordinating more than 30 observatories to look for exoplanets: https://exoplanetschannel.wixsite.com/home/project and we were able to find some new exoplanet candidates: https://www.universetoday.com/147231/saturn-sized-planet-found-in-the-habitable-zone-of-another-star-the-first-planet-completely-discovered-by-amateur-astronomers/ Now I have the intention to do the same, but looking for radio signals of possible extraterrestrial origin. The project I pro
  7. Hello, I recently wrote a paper (which I present here) suggesting which star has the highest probability of being the source of the WOW! Signal. Do you think that we should reply to the WOW! Signal or not?
  8. Hello! Does anybody have a backyard small radio telescope able to track specific stars and a feedhorn able to cover 1420 Mhz? Cheers!
  9. Hello, For those interested, I'm doing a live streaming of Tau Ceti: Hope you like it
  10. Hello, I wanted to share this interview of John Godier titled 'Is Interstellar Travel Possible?': https://youtu.be/UquRC-uMlqU What do you think? do you think it's achievable this century?
  11. Hello! I was recently interviewed by the Interplanetary Podcast regarding Solar One, a crewed interstellar spacecraft that I propose. For those interested, this is the podcast: https://www.interplanetary.org.uk/post/197-solar-one-alberto-caballero Clear skies!
  12. As some of you might know, I have designed a crewed interstellar spacecraft that I call Solar One. Basically, large flexible mirrors placed near the Sun would propel a one-mile light sail with a 4–crew spacecraft of 300 tons. To decelerate, an on-board compact fusion reactor would power a photon rocket placed at the front of the spacecraft that would 1) help decelerate and 2) ionize space hydrogen for the nuclear reactor. A Bussard scoop also placed at the front of the spacecraft would 1) collect those protons (ionized hydrogen) and 2) decelerate the spacecraft. Solar One w
  13. Hi everybody, I would like to share with you a crewed interstellar spacecraft which I have designed and called Solar One. It employs a combination of 3 propulsion methods: nuclear fusion, beam-powered propulsion , and photon propulsion. Basically, several compact fusion reactors power a laser system that propels a huge light sail. Physicist Robert Forward already proposed in 1983 to use a 26-TW laser system to propel a 100-km light sail, a fresnel lens to focus the beam of the laser, and decelerate the spacecraft with a secondary light sail. I propose something a bit d
