    That's amazing.

    Has anyone looked at Jupiter over the past week or so? It's at it closest point to earth and is in the southern sky just down and left of the moon. It looks amazing. So bright. And if you have even a modest telescope you can see its moons and red spot.

        i wonder if you can see it through a telescope and I also wonder how the hell that happened.

          The origin of the Wow! signal from 1977 was finally figured out. Spoiler, it's not aliens.

          Just before midnight on August 15, 1977, a scientist spotted an unusual radio blast while scanning the stars for possible signs of extraterrestrial life as...


          Professor Antonio Paris, an astronomer at St Petersburg College in Florida, believes that the signal wasn't from aliens – but was in fact two comets passing Earth on that very day.

          After going back through the records of that night Paris found that comets 66P/Christensen and P/2008 Y2 (Gibbs) were both in the area where the Wow! signal was originally detected. He suggested that a cloud of hydrogen gas in the wake of the comets triggered the powerful signal.

          So to prove his theory, he waited for the comets to fly past Earth again this year as part of their orbits around the Sun every 7 years or so. He saw that the comets produced the same kind of strong signal as the one detected by Ehman in 1977, putting an end to the mystery that perplexed scientists and conspiracy theorists for the past 40 years.

            Not sure if this belongs in a TV thread or in here, but I watched a 2011 documentary called Everything and Nothing on my Amazon Prime TV and I would highly recommend it to any scientifically inclined folks. It does drag in some spots, but Jim Al-Khalili (the British-Iraqi professor/narrator) does a really nice job explaining some concepts that are traditionally really difficult to explain. I don't think I've seen a clearer explanation of either parallax or of the Heisenberg Uncertainty Principle on TV. It also doesn't spend the vast majority of the 2 hours on the Copernican revolution or on lionizing Albert Einstein--both play relatively minor roles over the 2 hours so that they can tackle some different subjects.

              Thanks, i'll have to find this doc. I find that most astronomy/astrophysics documentaries and TV shows either dumb things down needlessly or lionize Einstein to the point of absurdity.

                Have any of you guys been looking at Jupiter next to the moon? It's absolutely beautiful. But I think the view peaked a few days ago. I got some pics on my phone but didn't do it justice.

                  I just printed this image of Jupiter on 4x2 vinyl.

                        This could have been bad, and is pretty scary



                        An asteroid flew pretty close to Earth last week. It missed us, you may have noticed. But we didn’t spot it until three days after it had flown past, which is a pretty terrifying reminder about the dangers asteroids pose to our world.

                          Literally just read about this a half hour ago. Probably wouldn't have ended life as we know it, but would have been pretty bad.

                          Also there is this: https://www.universal-sci.com/headli...wl-wcm27-3ctzc

                          Evidence continues to mount for life existing outside of earth.

                          Also just wanted to say that if we are able to find even simple lifeforms on Titan, Enceladus, or Europa, that would just completely open the floodgates because it would be all but certain that if we found life in our own solar system, the rest of the universe would be teeming with life. We could be close to the most important discovery in our history.

                            Were you able to see it with naked eye?




                            In other news I wanted to try and film the eclipse with my galaxy s8. Anyone know anything about that?

                            Figured just need a mount and a decent lense that fits on phone well. Maybe a filter of some sort?

                                Do any of you guys have any book recommendations for constellations?

                                I love looking at the night sky and took astronomy in high-school, but only remember a handful of constellations.
