I just had a random question and thought of you: Recently, astrophysics discovered that a lot of the really heavy elements (for example gold) are created in neutron star collisions (if memory serves). Could a potential solution to the fermi paradox be that there havent been enough of these collisions for earlier civilisations to have been able to discover / invent space technologies? I.e. gold can be very usefull in electronics. Maybe earlier civilisations didnt have the materials needed to reach the electronic age and are stuck in an earlier age due to a lack of resources / elements on the home planet? Steven Utter The laaava. You say it as if you're about to say Llama. Taner Ali I think it will be awesome if you make a video (or two) about the 2018 NASA Innovative Advanced Concepts awards. They are always very interesting and you manage to convey complex information very well, keep up the good work and thanks! Predrag Bubalo If there are open vents and geysers of water breaking through the surface on Europa, why the need to drill through the kilometres of ice? Couldn't the probes gain access to the water through these vents and geysers? Jeffrey Gould Hello Fraser,Since some white dwarfs and neutron stars have been found to spin at incredible speeds, I was wondering if they may come close to flinging anything off their equator, or even cancelling a significant fraction of their own tremendous gravity at the surface. Is this even possible within our laws of physics? Mighty13 Don't know how NASA will respond if an innovative project such as BFR really comes to life. Bryan Blatz Fraser, why the green screen nature background and piped in nature noises? Would an astronomical background be more appropriate? Guybrush Threepwood Hi Fraser, how big was the observable universe before the Big Bang? Lesley B HI Fraser, I like your channel a lot. I have a question. What will happen to Jupiter when it stops being active? Will it loose it's atmosphere? will there be a surface? What will it look like? Greetings Lesley. Locut0s Do you ever feel you live both at the best and worst time in human history in terms of space exploration, and cosmology? I feel we have picked a lot of the low hanging fruit and that despite there still being much more amazement to come, we are now looking at missions, probes, telescopes, and physics experiments that require more and more funding and longer and longer planning. At the speed of progress of other technologies like the advancements in AI, materials science, biology etc, I can only imagine where we will be at the end of my life. But by comparison many missions and new promising probes, telescopes etc, take 20 to 30+ years to come to fruition. This can seem disheartening at times. ferusgratia Hey Fraser! Thanks to all the work you and Youtubers like you do, I feel like I have a much better grasp of space and to some extent Cosmology. That said it's been a bit since I've had my mind blown by some new fact. I think I'm ready to delve into materials that would be hard to cover on Youtube, but I don't think I'm ready for hardcore scientific journals. Do you know of any good "middle ground" resources? Thanks! Alpha581 Love your videos as always.I have an interesting question for you.Assuming that the universe is infinite and you travel far enough will you eventually meet an exact copy of Earth and humans by random coincidence? Norman1951 Norman Fraser QUESTION: What percentage of exoplanetary systems align with earth in such away that their orbital planes pass across their star's disk as seen from earth? I can't imagine that it would be very high. Great show.

According to Gizmodo, in 2008 a large meteor detonated above Sudan, covering the area with shards of material. Scientists have been collecting and analyzing these samples to see what can be learned from them. New research indicates that there was likely a Mercury or Mars-sized planet that has been shredded and scattered throughout the system. The 80-ton meteorite is known as Almahata Sitta, and is the first significant evidence that another proto-world existed long ago in our solar system. This micro world may have collided with another proto-planet and caused a huge debris field to get scattered across the solar system. It is speculated this helped to seed many of the planetary bodies we see today, like Earth. https://www.geek.com/science/diamonds-found-in-meteorite-tell-story-of-destroyed-planet-1737483/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

NASA's Mars Cube One, or MarCO, is heading to deep space to test a first-of-its-kind technology demonstration: near-real-time communication between Earth and Mars using CubeSats. Learn more about the MarCO mission at: https://go.nasa.gov/marco_launch

On April 19, 1971, the Soviet Union launched the world's first space station, Salyut 1. This space station was a modified version of the Soviet Union's Almaz space station, which was part of a highly classified military program and was still under development at the time. After NASA managed to put astronauts on the moon, the Soviet Union decided that its next big feat in the Space Race would be to put a crewed space station in orbit. The first crew to visit Salyut 1 in orbit launched just four days after the space station did. However, that crew had some technical problems while trying to dock with the space station in their Soyuz spacecraft, so they went back home without ever actually entering the station. Another crew launched two months later, and after a successful docking, they spent 23 days aboard the station.

This week I get help doing the forecast from a team of stealthy solar storm experts, who have all gathered in Bern, Switzerland for an ISSI team meeting. The Sun has also chosen this week to become quite active with multiple bright regions that will boost the solar flux for amateur radio operators and emergency responders. We also have a coronal hole that will be sending us some fast solar wind in the next few days, which brings good news for aurora photographers, especially at high latitudes. Come meet the ISSI team of physicists, who are helping shape the future of space weather prediction, catch up on some recent aurora photos, and see what else the Sun has in store!

SpaceX is launching a brand new, and quite possibly one of the last non-block five Falcon 9's for NASA at 22:51 UTC (6:51 Eastern) out of Cape Canaveral Air Force Station's SLC-40. SpaceX will be attempting to land this booster on "Of Course I still Love you." TESS is the Transiting Exoplanet Survey Satellite and was manufactured by Orbital ATK and led by MIT to help search for exoplanets orbiting other stars.

Earthlings have been unsuccessful in the ongoing quest to find aliens from outer space. Here are three scary possibilities for why that has been the case.

An asteroid called 16 Psyche that resides between Mars and Jupiter is "95 percent or more" metal.
