By way of Follow Me Here, Gizmodo looks at five massive telescopes that will change the game, including the James Webb Space Telescope, a.k.a. Hubble 2.0. “Since blowing past its initial budget and launch data, NASA promises the ambitious project is on-track for 2018. And it better, because astronomers are eagerly awaiting its data.”
And here’s your counterpoint: Creationist Ken Buck argues that space exploration is a boondoggle because aliens are going to Hell anyway. “Ham argued that ‘secularists are desperate to find life in outer space’ as a part of their ‘rebellion against God in a desperate attempt to supposedly prove evolution.'”
Erm, yeah. I would hope the John Olver rule is in effect if and when this fellow is inevitably queried about his views on television, against Bill Nye or Neil DeGrasse Tyson or somesuch.
New planets have been discovered at a pretty decent clip of late. But, in a milestone, NASA’s Kepler Telescope finds in Kepler 186f, 500 light years away, “the first Earth-size planet orbiting a star in the ‘habitable zone’ — the range of distance from a star where liquid water might pool on the surface of an orbiting planet.” (“Earth-size” being the key word here — Kepler has previously found larger planets in the habitable zone.) To put it all down and start again, from the top to the bottom and then…
Update: Interesting speculation: Does Kepler 186f bode ill for our future? “This apparent absence of thriving extraterrestrial civilizations suggests that at least one of the steps from humble planet to interstellar civilization is exceedingly unlikely. The absence could be caused because either intelligent life is extremely rare or intelligent life has a tendency to go extinct.”
NASA sets aside some money for a robotic mission to Europa. “No details have been decided yet, but NASA chief financial officer Elizabeth Robinson said Tuesday that it would be launched in the mid-2020s.”
NASA announces 715 new planets found by the Kepler telescope, and that’s only from the first two years of data. “About 94 percent of the new alien worlds are smaller than Neptune, researchers said, further bolstering earlier Kepler observations that suggested the Milky Way galaxy abounds with rocky planets like Earth…four of the worlds are less than 2.5 times the size of Earth and reside in the ‘habitable zone,’ that just-right range of distances that could allow liquid water to exist on their surfaces.”
Via io9, Scientists at NASA’s JPL find the strongest evidence of currently extant water on Mars yet. “We still don’t have a smoking gun for existence of water…Although we’re not sure how this process would take place without water.”
Where do bad folks go when they die? They don’t go to heaven where the angels fly. Mars? Hrm…well, maybe. Curiosity finds the remnants of what appears to be an ancient Martian lake in Yellowknife Bay, part of Gale Crater. Unfortunately, “[e]ven if there were fossils in the mudstone, Curiosity doesn’t have the right kind of equipment to see them. That job will be left to the Mars rover set to launch in 2020.”
(Klaatu barada nitko?) All that being said, one Comic-Con remake reveal I can get excited about — although “Executive Producer Seth McFarlane” gives me a moment of pause — is Neil DeGrasse Tyson’s upcoming 13-episode reboot of Cosmos.
“‘There’s never been a more important time for COSMOS to re-emerge than right now. I want to make this so entertaining, and so flashy, and so exciting that people who have no interest in science will watch just because it’s a spectacle,'” MacFarlane said in a news release.”
Of late, astronomers have been finding new planets all the time, including one right in our cosmic backyard. Still, these two seem special: NASA has found two of the most Earth-like planets yet in Kepler 62f and Kepler 62e, 1200 light years away.
“The Kepler 62 system resembles our own solar system, which also has two habitable planets: Earth and Mars, which once had water and would still be habitable today if it were more massive and had been able to hang onto its primordial atmosphere.”
Hey neighbor: Astronomers find an Earth-like planet just next door in Alpha Centauri, the nearest star system to our sun. “Indeed, Alpha Centauri Bb is the first planet with an earth-like mass ever found orbiting a sun-like star.” That being said, prospects for life — or colonization — seem, for the time being, remote. “Unfortunately for any hope of finding life on this world, it orbits only about four million miles away…This would make Alpha Centauri B more than twenty times larger in the planet’s sky than the sun is here on earth…and more than 500 times brighter and hotter.”
A NASA/JPL simulation of Titan’s atmosphere suggests a chaotic chemical brew conducive to life on Saturn’s most interesting moon. “Now we know that sunlight in the Titan lower atmosphere can kick-start more complex organic chemistry in liquids and solids rather than just in gases.” (Titan image via this 2011 post.)
Data from Kepler’s Space Telescope suggests that an estimated 6% of red dwarf stars have planets in the habitable zone, meaning, statistically, we are basically surrounded by inhabitable worlds. “Our Sun is surrounded by a swarm of red dwarf stars. About 75 percent of the closest stars are red dwarfs.”
“Under the agency’s procedures, the box should not have been opened without knowledge of a NASA scientist who is responsible for guarding Mars against contamination from Earth. But Planetary Protection Officer Catharine Conley wasn’t consulted. ‘They shouldn’t have done it without telling me,’ she said. ‘It is not responsible for us not to follow our own rules.’“
It seems NASA’s Curiosity may have inadvertently brought Terran microbes along with it, which could become hugely significant if the robot encounters water, in which case they become either the potential seeds of new life on Mars and/or the 21st-century equivalent of the smallpox blanket. Er…oops.
Meanwhile, while we’re bringing life to Mars, Jupiter may have once again protected us from a Deep Impact/Melancholia-like disaster. “This is the third time since 2009 amateur astronomers have witnessed an impact flash on Jupiter. The massive gas giant, which exerts considerable gravitational pull, is something of a cosmic whipping boy in our solar system, regularly shielding inner planets like Earth from potential collisions.” So, if you’re keeping score at home, that’s Jupiter 3, Bruce Willis 1.
The Land of Chocolate? Astronomers find sugar molecules orbiting young star IRAS 16293-2422, 400 light years away. “‘A big question is: how complex can these molecules become before they are incorporated into new planets?’ Jørgensen said. “This could tell us something about how life might arise elsewhere, and ALMA observations are going to be vital to unravel this mystery.'”
By way of Eric of Kestrel’s Nest, our radio telescopes find signs of life on Mars…us. Hey, at least the system works. Although, does anyone else have a problem with UNC-Chapel Hill calling their robotic telescope network SKYNET? Inviting calamity, I say.
And we know exactly whose fault it is. In response to the 35-year-old “WOW signal“, we the people of Earth have apparently chosen as our herald Stephen Colbert, whose response above will be broadcast in the direction of its origin by National Geographic via the Arecibo radio telescope.
Hrm….isn’t the Mighty Colbert a bit too droll for alien intelligences? I fear this will set off a Douglas Adams-style miscommunication that will end very badly for all parties involved. Second, why would any alien race be able to make sense of Prometheus? There was no sense there to be had.
Moreover, just today scientists announced the discovery of two Earth-sized planets — Kepler 20e and Kepler 20f. “‘For the first time, we’ve crossed the threshold of finding Earth-size worlds,’ Torres says. ‘The next step is having an Earth-size planet in the habitable zone.’” And apparently Kepler 20f may have once had water, not unlike a planet closer to home…
“This is the single most bullet-proof observation that I can think of that we’ve made this entire mission regarding the liquid water.” Something to consider if we don’t manage to tackle global warming by 2006 — the prior existence of water on Mars is further confirmed through a trail of gypsum left within an ancient rock. “Both the chemistry and the structure ‘just scream water,’ Squyres added.“
And, on a grander scale, astronomers have begun to uncover supermassive black holes (no, not those ones) at the centers of galaxies. These are “the biggest, baddest black holes yet found in the universe, abyssal yawns 10 times the size of our solar system into which billions of Suns have vanished like a guilty thought.” In other words, plenty of room for Maximillian Schell to get lost in there…Tread carefully.
From a few weeks ago and languishing in the bookmarks, scientists find nematodes a mile below the Earth’s surface, raising the possibility of similar life on other worlds. The spice must flow… “The two lead researchers…said the discovery of creatures so far below ground, with nervous, digestive and reproductive systems, was akin to finding ‘Moby Dick in Lake Ontario.‘”
Another casualty of the lousy economy and the budget crises (in this case, California’s) SETI’s Allen Telescope Array goes dark. “‘We have the radio antennae up, but we can’t run them without operating funds,’ he added. ‘Honestly, if everybody contributed just 3 extra cents on their 1040 tax forms, we could find out if we have cosmic company.‘”
