Researchers at the European Space Agency harness the natural lensing properties of cosmic gravity to get a closer look at a black hole.

If you think asteroids are rare, it’s only because they’re so small and dark and hard to see. An eye-opening new video (above) shows what the night sky would look like if we could see the near-Earth asteroids astronomers have discovered — it’s quite a swarm.

Black holes are, by definition, impossible to see by conventional methods and are often further obscured by thick blankets of dust or gas. But that’s not an issue for NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR). It can peek through the obscuring layers and monitor the black holes via the high-energy X-rays that they emit. And, after a recent survey that spotted five previously unknown supermassive black holes in the centers of various galaxies, NASA researchers now think there could be millions of of them dotting the Universe like the holes of an intergalactic colander.
“Thanks to NuSTAR, for the first time, we have been able to clearly identify these hidden monsters that are predicted to be there, but have previously been elusive because of their surrounding cocoons of material,” said George Lansbury of Durham University in a statement. “Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole universe, then the predicted numbers are huge and in agreement with what we would expect to see.” The team’s research has been accepted for publication in The Astrophysical Journal.
According to the reputable Australian astro-enthusiast journal, SkyNews, a leading biologist says that it is surprising we have not already discovered extra-terrestrials that look like us — given the growing number of Earth-like planets now discovered by astronomers.
Simon Conway Morris, an evolutionary biologist suggests that aliens resembling humans must have evolved on other planets. He bases the claim on evidence that different species will independently develop similar features which means that life similar to that on Earth would also develop on equivalent planets.
The theory, known as convergence, says evolution is a predictable process which follows a rigid set of rules. Read the full story at Skynews…

“The first marketable, personal computers in the late 70s came about after almost 40 years of research and development, which created the technology at public expense. One of the peculiarities, if you’d like, of our system of innovation and development is that it’s radically anti-capitalist in many ways…People who paid taxes in the 50s and 60s may not have known it, but they were creating what was ultimately marketed by Apple. But they don’t get any of the profit. I think that’s a social pathology and the same carries over into space.” Read more
[The Washington Post] The explosion was the third failed attempt to resupply the space station with cargo in recent months.
“We (“we” meaning robots, at least at first) need to do lots of lunar experiments. What’s the nature of the Moon’s poles? Where is the water stored? We can answer those questions using robots—a couple of surface rovers, like Curiosity on Mars. These rovers can measure temperatures, slopes, surface properties, and the measurements of existing ice. Once we figure out a way to locate this vital resource on the Moon, the real progress can begin.” Read more
