This is how colossal NASA's new Hubble Space Telescope successor is.The first images from the James Webb telescope are finally here.NASA highlights a massive black hole blazing fiery plasma trails across the cosmos.NASA releases stunning photo of beautiful blue dunes on Mars.To us, it just sounds like a beginning of a very sinister dubstep track. As NASA explained it back then, "Astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note - one that humans cannot hear some 57 octaves below middle C." The galaxy cluster you're "hearing" is Perseus, the data comes from NASA's Chandra X-ray Observatory, and the recording was released back in May (opens in a new tab) for NASA's Black Hole Week. Here it's amplified, and mixed with other data, to hear a black hole," NASA's account dedicated to exoplanets tweeted. A galaxy cluster has so much gas that we've picked up actual sound. "The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. NASA made this very apparent on Sunday, sharing what the agency described as the sound of a black hole, available to human ears in listenable format.Īnd if you're wondering how the hell does sound travel in the vacuum of space, NASA has an explanation. When we are reasonably close to having the required technology, we can work on a black hole probe.In space, no one can hear you scream – unless you're a supermassive black hole. It's far better to focus on things that are within our reach (the Moon, and Mars for manned missions, other planets and possibly our outer solar system for probes), and use these goals to improve out technology. In light of that, the cost is very hard to justify. With all these hurdles, we don't even know where to start on making such a probe, (and if we did, we would have to wait a long time to make it and a lot more time to get results). Getting to the technological levels listed above probably would cost many, many times more than the entire world economy put together. If the probe is going at near light speed, it will take a lot of fuel to deflect its path. We could include an onboard computer that is able to dynamically correct the path, but this requires extra fuel on the ship for thrusters. We don't have the technology to aim so well.This means that will have to set it on a very precise path and then just pray we aimed it right. This can't be done for a probe that's going so far away. We have a 4 minute lag for the Mars rovers, which isn't too bad because we can still respond to new data. There's no way to tell the probe what to do once it's gone. To reach such speeds one needs to accelerate, and for that the probe needs to carry lots of fuel, which in turn makes it harder to accelerate. Propulsion technology has improved since then, but not the the extent that we can send something at near light speed. Voyager 1 is a pithy 125 AU away from us. We don't have near-light-speed propulsion technology.It would take very, very long to get results. No black hole candidates are close to us.If you want to send a very expensive probe on a mission to inspect a black hole, you need to first be sure that it indeed is a black hole. We're not yet entirely sure of any black holes being black holes.
