In case you’ve decided that this world no longer holds any charms for you, good news! This week’s space updates include a lot of promising research into getting you off this rock. Space ahead!
Things that go BOOM!
NASA’s Heliophysics program – which monitors the sun, get it? “Helio?” – has an amazing compilation of videos of what they call a “prominence,” or a blast of solar radiation. The videos compile several different distances, bands of energy and even two completely different sides of the same explosion.
Meanwhile, we have also recorded and are studying the largest star explosion ever recorded.
Come to the Off-World Colonies
The first and most basic problem we have as a species in visiting other worlds. Sure, provided that we stay within our own solar system, travel is not that far. Visiting any of Jupiter’s moons, for example. But if we’re to really break the bonds of our home system, it requires light speed travel.
New research puts light speed travel within at least hypothetical reach, though. Close enough in reach, in fact, that NASA actually has some basic testing in the works. The concept put forth decades ago as a “warp bubble,” which compresses space time ahead of it while expanding space-time behind it, might be possible for both sub- and superluminal (slower and faster than the speed of light, respectively) travel.
Now for the bad news: the nearest star and potentially-inhabitable exoplanet to the Earth is Alpha Centauri Bb at a whopping 4.25 lightyears away. So at light speed, assuming it can be achieved, we’re still looking at 51 months of crappy spaceline food and kids kicking the backs of our seats before we get to our destination.
As for our next stop, humanity’s original spacefarers have ideas of their own. Buzz Aldrin was quoted this week as saying that humanity’s future lies on the surface of Mars
Buzz Aldrin: Humanity’s Future Is on Mars:
Aldrin’s plan calls for NASA and the United States to focus technology development efforts for a manned Mars mission while still remaining a global leader in human spaceflight. The plan does not completely forgo a return of astronauts to the moon, but does state that NASA should not send astronauts there. Instead, his plan states, other countries like China, India and Russia can focus on exploration of the lunar surface while NASA fine-tunes the tech needed for Mars trips from stable Lagrange points near the moon.
Meanwhile, as the debate continues about the feasibility of travel both in and out of the Solar System, others continue to explore exoplanets in ways both innovative and old-school. One method for understanding the makeup of expolanets is to borrow slightly from the world of star analysis and use spectometry to see the signatures of elements. In this case, rather than putting the light of stars through a prism to determine the elements being burned off, the light of the stars as it passes through exoplanets as the occlude our view of the star is being analyzed for the same data about the possible atmospheres and planetary make up of our new long-distance BFFs.
Odds and Ends
If you’re looking for a way to contribute to deeper space exploration, why not try NASA’s call to search for “Space Warp” galaxies? No, these are not galaxies traveling at the speed of light. These are galaxies who by their nature create telephoto lenses into even deeper space. NASA hopes to be able to use these galaxies to peer deeper than ever before into the cosmos, and with much greater detail.
And finally, it turns out that the Milky Way’s own resident black hole has a surprising taste for gasses. Whereas scientists expected to find the crushed remnants of stars at the center of our galaxy – being dragged inevitably towards the deadly embrace of a super-massive black hole that keeps time in the Milky Way – they have instead discovered a collection of gasses equivalent to the size of our own Earth about to be gobbled up within the year.
That’s it for this week, space fans!
