Didn't think this needed another thread, but wanted to post. Pretty impressive test flight of the SpaceX Falcon Heavy.

SpaceX Launches Falcon Heavy In Spectacular Show


SpaceX's Falcon Heavy, the world's most powerful rocket, thundered to life and shot away from Florida Tuesday on the power of 27 engines and nearly 5 million pounds of thrust, kicking off a spectacular maiden flight to send founder Elon Musk's cherry red Tesla Roadster on a "just for fun" journey beyond the orbit of Mars.


It was easily the loudest and possibly most dramatic launch from Florida's "Space Coast" since NASA's space shuttle was retired in 2011 with the Falcon Heavy, made up of three strapped-together core stages powered by nine engines each, putting on a dazzling show for tourists and area residents jamming nearby roads and beaches.

Spectacular as it was, the launching was just the appetizer for a long-awaited test flight. Eight minutes after the rocket took off, two of the three Falcon 9 core stages that helped power the vehicle out of the lower atmosphere made rocket-powered descents to side-by-side touchdowns at the Cape Canaveral Air Force Station, generating thunderous sonic booms as they slowed for landing.

New Mars discoveries advance case for possible life

CAPE CANAVERAL, Fla. (AP) — New Mars discoveries are advancing the case for possible life on the red planet, past or even present.

Scientists reported Thursday that NASA's Curiosity rover has found potential building blocks of life in an ancient Martian lakebed. Hints have been found before, but this is the best evidence yet.

The organic molecules preserved in 3.5 billion-year-old bedrock in Gale Crater — believed to once contain a shallow lake the size of Florida's Lake Okeechobee — suggest conditions back then may have been conducive to life. That leaves open the possibility that microorganisms once populated our planetary neighbor and still might.

"The chances of being able to find signs of ancient life with future missions, if life ever was present, just went up," said Curiosity's project scientist, Ashwin Vasavada of NASA's Jet Propulsion Laboratory in Pasadena, California.

Black Hole Photographed for 1st Time

Black holes have finally been dragged out of the shadows.

For the first time ever, humanity has photographed one of these elusive cosmic beasts, shining light on an exotic space-time realm that had long been beyond our ken.

"We have seen what we thought was unseeable," Sheperd Doeleman, of Harvard University and the Harvard-Smithsonian Center for Astrophysics, said today (April 10) during a press conference at the National Press Club in Washington, D.C.

Doeleman directs the Event Horizon Telescope (EHT) project, which captured the epic imagery. These four photos, which were unveiled today at press events around the world and in a series of papers, outline the contours of the monster black hole lurking at the heart of the elliptical galaxy M87.

People aren't grasping the significance of this historic achievement. The fact that we are all alive to see this should be considered an incredible privilege. We now have visual proof of the bending of space time. Just incredible.

Cool story for you. We actually had the visible evidence of bending of space from a picture of an total eclipse. Einstein predicted it in the theory of relativity. Several groups took off in the 20's or 30's. Can't remember exact date. A trippy story in own right. Soviet spies and such. Back to the main story-these men caught a photo of the star light bending around our sun.

Here's a pic like they took. The famous diamond ring eclipse. The starlight bending around our star and bending back to our view.

Good find, fascinating theory coming of age. Now, if we can just get to the core of a black hole without becoming spaghetti.

From what I understand, they did this with radio telescopes and not optical. So images provides are representations of the radio data, and not really direct visual observation (visible light spectrum).

pretty cool all the same.

Yep, the image in the link actually says "eight ground based radio telescopes captured this image". I would love to know how they transfer that into visual data, (I'm sure a computer is involved) but it's interesting nonetheless.

one thing I've often wondered is.... why do we have telescopes that can see billions of LIGHT YEARS away, instead of building something that would let us look at say... Mars or Pluto, or something in our galaxy much more clearly?

It's sort of cool that we can look and see what might have existed billions of years ago, but it's not much use to us now, we don't even know if it still exists.

as opposed to getting a really good look at something close, like maybe time-lapse to see how it changes over a year or a decade... seems like that would yield more useful information.

I don't claim to be an astrophysicist, but I pay attention to a lot of these news items. I get the impression NASA with all it's science nerds, is more interested in pursuit of pure scientific gains, answering questions about how the universe and all it's parts formed than many of us really get that excited about. To me, the possibility of life on a moon of Jupiter is more interesting than what happens if 2 black holes bump into each other a somethingillion miles away.

The trend is shifting a bit though with the attention going to the surge in discoveries of exoplanets and search for another earthlike planet. Also, the Spacex types are driving the agenda to putting people back on the moon and Mars. NASA has achieved amazing things, but they have demonstrated a consistent lack of honesty in budgeting forecasts and rely on their unprecedented accomplishments to hide their lack of accountability.

One of these days we'll find pretty good signs of some life on an exoplanet or an exoplanet that appears to be very similar to earth and that will excite Joe taxpayer enough to push the agenda down more of an astrobiology and SETI path.
