Peering into a Black Hole – New Event Horizon Telescope

Peering into a Black Hole – New Event Horizon Telescope

     Ever since first mentioned by Jon Michell in a letter to the Royal Society in 1783, black holes have captured the imagination of scientists, writers, filmmakers and other artists. Perhaps part of the allure is that these enigmatic objects have never actually been

“seen”. But this could now be about to change as an international team of astronomers is connecting a number of telescopes on Earth in the hope of making the first ever image of a black hole.

On April 5-14 2017, the team behind the Event Horizon Telescope hopes to test the fundamental theories of black-hole physics by attempting to take the first ever image of a black hole’s event horizon (the point at which theory predicts nothing can escape). By connecting a global array of radio telescopes together to form the equivalent of a giant Earth-sized telescope – using a technique known as Very Long Baseline Interferometry and Earth-aperture synthesis – scientists will peer into the heart of our Milky Way galaxy where a black hole that is 4m times more massive than our sun – Sagittarius A* – lurks.

      (CNN)NASA is tantalizing the world with big Mars news.

It says a mystery enshrouding the Red Planet has been solved.

The space agency is scheduled to announce a “major science finding” on Monday.

A special news conference is slated for 11:30 a.m. ET, and will be broadcast live on NASA Television as well as its website.

NASA on Thursday announced on social media that it would reveal news of a Mars discovery, sending space fans into a speculation frenzy. […]

Patent Granted for ‘Space Elevator’

Space Elevator

     … So far, most space elevator concepts have been the stuff of sci-fi, and any plans to actually build one have remained on the rather distant horizon. But “push button” access to space took a step toward reality in late July when the US Patent and Trademark Office granted a patent to a Canadian company for its invention of an inflatable space elevator tower.

Thoth Technology, based in Pembroke, Ontario, devised a tower design using pressurized segments that reach up to 20 kilometers (12.4 miles) into the stratosphere where a platform could be constructed for purposes of communications, tourism or as a launch platform for reaching space. Unlike blasting off from near sea level, as most space launches do now, getting into orbit or beyond from the top of a space elevator more than 20 times taller than the highest structures on Earth would be more like an aircraft takeoff. …

NASA Releases Space Nuclear Power Study | Space News

NASA Releases Space Nuclear Power Study

     NASA has released a long-awaited Nuclear Power Assessment Study that examines the prospects for the use of nuclear power in civilian space missions over the next 20 years.

The Study concludes that there is a continuing demand for radioisotope power systems, which have been used in deep space exploration for decades, but that there is no imminent requirement for a new fission reactor program.

The 177-page Study, prepared for NASA by Johns Hopkins University Applied Physics Laboratory, had been completed several months ago but was withheld from public release due to unspecified “security concerns,” according to Space News. Those concerns may have involved the discussion of the proposed use of highly enriched uranium as fuel for a space reactor, or the handling of plutonium-238 for radioisotope power sources.

Nuclear power can be enabling for a variety of space missions because it offers high power density in compact, rugged form. Radioisotope power sources (in which the natural heat of decay is converted into electricity) have contributed to some of the U.S. space program’s greatest achievements, including the Voyager I and II probes to the outer solar system and beyond. But development of nuclear reactor technology for use in space has been dogged by a repeated series of false starts in which anticipated mission requirements failed to materialize. . . .
