For 25 years, Hubble—the flagship of Earth’s fleet of orbiting telescopes—has sent home some sweet science. And sometimes it just takes some pretty pictures, too. No apologies, none needed.

The image above captured a rare triple eclipse, three of Jupiter’s moons transiting across its sunward face. “Hubble has been important for science, but we felt that there are images that have aesthetic value above and beyond their scientific value,” says the awesomely named Zolt Levay, who works with the Space Telescope Science Institute, which coordinated with Hubble’s directors for this bit of opportunistic armchair space tourism.

Capturing the event was a huge stroke of luck. Eclipses—when one planetary body casts its shadow on another—only happen under specific conditions. “This is similar with eclipses on the Earth,” says Mike Wong, a UC Berkeley scientist who works with Hubble. Every planetary system has an “eclipse season,” which depends on the inclination of the moons’ orbits in relation to the sun. “There are only two times a year when you’ll have shadows going across the surface of the planet,” Wong says. In Jupiter’s case, this alignment of three moons has only happened twice in the last 15 years, and won’t happen again until 2035.

And then there was the issue of whether Hubble would be in position to make the shot. Wong says news of this eclipse caused a buzz in the research community, but because of Hubble’s orbit—it circles the earth every 96 minutes—they weren’t sure it would have a view. “We were lucky that Hubble was on the right side of the planet Earth when these moons were transiting,” says Wong.

And no, this kind of imagery won’t help in the hunt for exomoons. One of the ways that Kepler—NASA’s high profile planet-hunting satellite—detects faraway planets is by looking for minuscule flickers in brightness that would indicate an orbital body passing in front of its star. But Kepler can barely make out Earth-sized objects. The signal-to-noise ratio is way too low for the telescope to pick out any extra-solar Callistas, Europas, or Ios. But really, who cares? This is just cool.

bluesbaby5050: JUPITER ASCENDING EXPOSES SOME OF THE UGLY TRUTH

JUPITER ASCENDING EXPOSES SOME OF THE UGLY TRUTH. I saw Jupiter Ascending in 3D yesterday. It was, ahem...interesting. It was on-the-nose writing and contrived. But, the Hollywood "scripters" know something - or they've been poking around sites like this one, finding out what's happening behind the scenes and behind the veil. And if that's the case, then that's great. But, I think these scriptwriters know more than meets the eye!

The movie plot was canned. The characters were bland. The acting was lame. But, the concept was based on truth. And the fact that it has been put on the big screen will allow this information to be brought to the masses - and hopefully wake them up to this "ugly" reality. Unfortunately, I'm being very optimistic here, and the masses will still remain undisturbed, unperturbed and unmoved.

Here are the concepts that the movie brings forth:

1) Reptilians

2) Grays

3) Overlords/demiurges/geneticists-creators

4) Ownership of Earth and other worlds

5) Birth place of Human race is elsewhere and not on Earth

5) Manipulation of time and matter

6) Harvesting planets

7) Humans as livestock

8) Reincarnation

9) Cloaked Ships and Cloaking devices

10) Life on this planet originated from elsewhere; and the copying, splicing/manipulation of the genes of certain Alien Species has created much of the life-forms that we see on this world.

Overall, the film is one gigantic overdose in special effects, explosions, fighting, spaceships and a cinematographic, roller coaster ride. It is dark - as this subject matter would be.

Is there a message in this movie? I didn't find one, like I would find in the Lord of the Rings trilogy. But, it still manages to bring out to the surface the despicable truth that human beings are in a world that seems to be under the control of nefarious beings or forces that don't have humanity's best interest. Maybe the movie serves to plant the seed of awareness to the masses. And maybe, if they run into this information again - via a a site, a video or a family member - they will tend to not walk away or scoff.

There is much that is happening behind the veil and the timing of this film couldn't have been more precise! HERE'S THE TRAILER: https://www.youtube.com/watch?v=t4ZzMkDLjWI&feature=player_embedded#t=0

Other Reviews from: http://www.rogerebert.com/reviews/jupiter-ascending-2015 are not very positive either. But, based on the comments from reviewers in general, it seems they are pretty clueless when it comes to this type of off-world and Earth-history information.

The White House Wants To Go To Europa

The White House Wants To Go To Europa [SAYS NASA]

Earlier this week the White House made public its budget requests for 2016. It’s a little bit of Washington kabuki—Congress always adjusts the budget one way or the other. But buried inside the $18.5 billion budget request for NASA was an interesting tidbit: $30 million for a mission to the Jovian moon Europa, every space nerd’s favorite target in the search for extraterrestrial life.

In other words, if this new funding goes through, it’ll mean that NASA is finally, officially onboard with a mission to the ice-crusted world where alien monoliths took over in Arthur C. Clarke’s 2010. In other other words: Let’s go to Europa! “This is a big deal,” says Casey Dreier, the director of advocacy at the Planetary Society, which has been lobbying for this mission for more than 15 years. “This budget basically fills in the missing piece that will enable this mission to go forward.” The new budget request also says that the White House plans to ask for even more money in the next few years, and because the mission is now an official project, says Dreier, civil servants can work on it and NASA can start making long-term contracts for further planning.

So what would the mission look like? Europa’s icy shell gives it the smoothest surface of any world in the solar system. But shifting cracks and other evidence suggest that that below that frozen surface lies an ocean—a watery one. And where there’s water, life may follow. Researchers have wanted to get there for decades—the current best idea for how is a 15-year-old concept called the Europa Clipper. “What we’ve been looking at is a multiple flyby mission,” says Bob Pappalardo, the mission’s project scientist. Under the current plan, a spacecraft will orbit Jupiter, not Europa—but it’ll zip past the moon 45 times in three years—venturing as close as 16 miles to the surface every couple of weeks.

Scientists are still hashing out what kinds of instruments will be onboard, so Pappalardo can’t say which exact ones will end up going to Europa. But one of the main goals will be to measure the moon’s magnetic field, which would tell scientists how salty the subsurface ocean is. Dissolved minerals (like salt) allow the ocean to conduct electricity—which means it’d have a magnetic field a sensor could read. Or more speculatively, in 2013 the Hubble Space Telescope spotted what looked like 125-mile high geysers spewing water from Europa’s south pole. Maybe a probe could actually fly through one and sample the water. Radar could reveal how thick the frozen crust is, and other instruments could measure the chemicals in Europa’s wispy atmosphere. High-resolution cameras will take pictures of the cracks that crisscross the surface, hoping to figure out whether it’s actually the case that the ice flexes and breaks because of that still-hypothetical ocean. And they’ll also scope out possible spots to send a future lander.

That’s the real brass ring, of course—if you want to find aliens. “If someone comes up with a clever way to point to life with multiple flybys, that will be wonderful,” Pappalardo says. “But that will probably take going to the surface.” That’s why Earthbound experiments like the work at Lake Vostok in Antarctica are so interesting to planetary scientists—cracking through 2.5 miles of ice to get to a liquid lake below without contaminating it may turn out to be highly relevant expertise someday.

When that’ll happen, though, is another question. The price tag for something Europa Clipper-like looks to be about $2 billion, so it’ll take a few more years of budgets to get it all together. A mission with a lander would be much more expensive. An orbiter might still be a possibility, but “it’s a riskier and more expensive approach than making many flybys,” Pappalardo says. It would take a year and a half after arriving at Jupiter just to get into Europa’s orbit, requiring lots more fuel and exposing the spacecraft to radiation that could fry its instruments.

However the details turn out, a Europa mission could launch as soon as the mid-2020s, said David Radzanowski, NASA’s chief financial officer, in a press briefing on Monday. Which means it won’t actually get to Europa until around 2030. But if all goes as planned, those 15 years will fly right by. - http://www.wired.com/2015/02/white-house-wants-go-europa/
