The Alpha Centauri System
When we eventually develop the capacity to leave our solar system, we will be ready to visit countless other worlds. Where will we go first? Probably the closest system to ours, since it'll be the fastest. Which system is that? The Alpha Centauri System, with three stars, and at least one planet, which we think may even be habitable. What do they look like? What do we know about them? Let's find out! Check out my original content on Graphy: https://share.graphyapp.co/ZYZX Subscribe: http://bit.ly/ProfDaveSubscribe

SHSSP19 - Interstellar Program Alpha Centauri
Guest Speaker: Dr Simon Peter "Pete" Worden Can we reach the stars?
No extraterrestrials have yet visited us – but neither have we stepped out onto the galactic stage. Are we destined to belong to Earth for as long as we survive? Or can we reach the stars? Breakthrough Starshot is a $100 million research and engineering program aiming to lay the foundations for a flyby mission to Alpha Centauri, our nearest star system, within a generation. This is one of several privately-funded global initiatives to answer the fundamental science questions surrounding the origin, extent and nature of life in the universe. The Breakthrough Initiatives are managed by the Breakthrough Prize Foundation.
Project Dragonfly. A Laser-Powered Probe to Alpha Centauri
The distances between stars are so vast, it’s hard to wrap your mind around it. Even our far flung Voyagers have barely reached interstellar space, and would take tens of thousands of years to get to even the nearest star. But scientists and engineers are considering what it would actually take to send a spacecraft to another star. It’s called Project Dragonfly, and would use existing or near future technologies to send a 3,000 kg spacecraft to Alpha Centauri within 100 years. Project Dragonfly paper

How Will We Get to Alpha Centauri?

Alpha Centauri: A Triple Star System about 4 Light Years from Earth
“A new study involving long-term monitoring of Alpha Centauri by NASA’s Chandra X-ray Observatory indicates that any planets orbiting the two brightest stars are likely not being pummeled by large amounts of X-ray radiation from their host stars. This is important for the viability of life in the nearest star system outside the Solar System.” Engage Warp Drive! Why Interstellar Travel's Harder Than It Looks
“How hard is it to hop to the nearest star system or soar across the galaxy? A typical "Star Trek" or "Star Wars" movie makes it look easy. When the heroes get a distant distress call, they use "warp drive" or "hyperdrive" and arrive at their destination within minutes or hours. If we got the right propulsion, would it be possible for us to voyage that quickly in real life?” Building Sails for Interstellar Probes Will Be Tough, but Not Impossible
“Giant lasers may indeed launch fleets of spacecraft to Alpha Centauri, given breakthroughs in the science behind extraordinarily thin, incredibly reflective sails that can catch this laser light, a new study finds.” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

A Tour of Alpha Centauri
In humanity's search for life outside our Solar System, one of the best places to look is Alpha Centauri, a system containing the three nearest stars beyond the Sun. A new study that has involved monitoring of Alpha Centauri for more than a decade by NASA's Chandra X-ray Observatory provides encouraging news about one key aspect of planetary habitability. It indicates that any planets orbiting the two brightest stars in the Alpha Cen system are likely not being pummeled by large amounts of X-ray radiation from their host stars. Alpha Centauri is a triple star system located just over four light years, or about 25 trillion miles, from Earth. While this is a large distance in terrestrial terms, it is three times closer than the next nearest Sun-like star. The stars in the Alpha Centauri system include a pair called "A" and "B," that we'll call AB, which orbit relatively close to each other. Alpha Cen A is a near twin of our Sun in almost every way, including age, while Alpha Cen B is somewhat smaller and dimmer but still quite similar to the Sun. The third member, Alpha Cen C (also known as Proxima), is a much smaller red dwarf star that travels around the AB pair in a much larger orbit that takes it more than 10 thousand times farther from the AB pair than the Earth-Sun distance. Proxima currently holds the title of the nearest star to Earth, although AB is a very close second. The Chandra data reveal that the prospects for life in terms of current X-ray bombardment are actually better around Alpha Cen A than for the Sun, and Alpha Cen B fares only slightly worse. Proxima, on the other hand, is a type of active red dwarf star known to frequently send out dangerous flares of X-ray radiation, and is likely hostile to life.
A Quick Look at Alpha Centauri
At a distance of only 25 trillion miles, the Alpha Centauri star system is a prime target in humanity's search for life outside our Solar System. Astronomers would like to know what kind of environment exists around the two stars in Alpha Centauri that closely resemble our Sun. To learn about this, NASA's Chandra X-ray Observatory has been monitoring the Alpha Centauri system every six months for over a decade. Chandra is the only X-ray observatory capable of resolving the two Sun-like stars to determine which star is doing what. A new study indicates these two stars are likely not pummeling any orbiting planets with large amounts of X-ray radiation. This is promising news for the sustainability of life on any planets astronomers find around these two nearby stars in the future.
Proxima B Update for March 5, 2018

"Proxima B" Hopes For Life Smacked Down
Scientists have discovered a flare off of the sun’s closest stellar neighbor, Proxima Centauri. Many are reporting that it could spell trouble for any hope for life on its exoplanet, Proxima b—but it might also kill off a presumed set of other planets around the star. Last fall, lots of folks, including me, reported on evidence of dust rings around Proxima Centuari. These potential rings would imply that the star could have an elaborate planetary system alongside its confirmed exoplanet, Proxima b.

NASA Looks To Alpha Centauri
NASA hopes to launch an exploratory probe to investigate the system of our nearest neighbor, the star system Alpha Centauri. The plan is to reach the star one hundred years after man set foot on the moon, in 2069.
A report in New Scientist reveals the plans of a group of engineers at NASA’s Jet Propulsion Laboratory in California. The mission concept was presented at the annual conference of the American Geophysical Union. It also promises to use technology that doesn’t exist yet.
The only spacecraft that’s ever left our solar system is Voyager 1. Alpha Centauri is 4.3 light-years away, or about 25 trillion miles to us Earthlings. A spacecraft like Voyager would take nearly 80,000 years to get there.

Astronomers have discovered a dust ring around Proxima Centauri is the closest star to the Sun. A report claims the dust ring’s detection could point to a significant planetary system around the star.
*Why massive galaxies don't dance in crowds
A new study has discovered that the rotational movement of a galaxy in a galactic cluster is determined by its mass rather than galactic density. The findings are based on a detailed study of over than 300 galaxies.
*Introducing the quarksplosion
Scientists have discovered the quarksplosion -- a blast that could be eight times more powerful than any thermonuclear bomb. Physicists have discovered that fusing two sub atomic elementary particles -- known as beauty or bottom quarks -- could result in the creation of a new primary particle, a secondary particle known as a nucleon and the release of huge amounts of energy -- some eight times more -- than a nuclear fusion reaction.
*Powering Enceladus active ocean
Heat from friction could power hydrothermal activity on Saturn's moon Enceladus for billions of years if the moon has a highly porous core. The new findings helps resolve a question scientists have grappled with for a decade: Where does the energy to power the extraordinary geologic activity on Enceladus come from?
*One of the oldest objects in the universe
Astronomers have discovered one of most distant galaxies ever seen dating back some 12.8 billion years. The findings provide new insights into the early history of the universe.
*SpaceX make it 16 in a row
SpaceX has just launched its 16th rocket this year – new record for the California company which has now flown the Falcon 9 more times than any other launch service provider has flown any other rocket. The SpaceX Falcon 9 blasted off from Kennedy Space Centre pad 39A at the Cape Canaveral Air Force Base in Florida carrying the KoreaSat-5A telecommunications satellite into geostationary transfer orbit.

Alien Life on Proxima b: A Second Earth or Waterworld? | Alien Analysis
Proxima b, also known as Proxima Centauri b, is the closest known exoplanet to our solar system that may be habitable to life as we know it. However, there are many challenges to overcome for biology to gain a foothold and evolution to be kickstarted. Because Proxima Centauri is a much dimmer Red Dwarf star, the habitable zone, where most water exists in liquid form, is many times closer to the star. Therefore, Proxima b will likely be both tidally locked, and pounded by solar flares, coronal mass ejections and ultraviolet radiation from its much more active host star. Also, it is possible that this exoplanet is a waterworld meaning that its mineral core is covered by ice. How could a planet drowned by water and irradiated from space be able to overcome these problems and host life? One possible solution may be surprising... Please also check out Parallaxicality's excellent video on Proxima b: https://www.youtube.com/watch?v=yR8HIDJsaHA&t=424s Some of the recent research used for this video follows below. NASA scientists claim that Solar Flares and radiation will have stripped oxygen and hydrogen from Proxima b's atmosphere:
https://exoplanets.nasa.gov/news/1409/planets-of-red-dwarf-stars-may-face-oxygen-loss-in-habitable-zones/ Proxima b's magnetic field may be strong enough to retain atmosphere - Dong, Chuanfei et al. (2017):
https://arxiv.org/pdf/1702.04089.pdf Proxima b may be a water world according to NASA:
https://www.nasa.gov/feature/jpl/study-planet-orbiting-nearest-star-could-be-habitable Side note: The recent news on the 7 earth-sized exoplanets around the nearby red dwarf star Trappist-1 is also highly significant in this light. Like Proxima b, the exoplanets around TRAPPIST-1 would probably also be tidally locked too and thus provide the same conditions. CREDITS: Ambient music:
