Radio Astronomers discovered hundreds of Quasars hiding in our galaxy.

Almost everything you could want to know about Saturn's sixth largest moon, Enceladus.

Quasars, or extremely active black holes are the brightest objects in the universe. But aren't black holes meant to be invisible? Based on the Illustris Project simulation, we also look at radio-mode and quasar-mode feedback, seemingly...

When the Americans tried to detect radiation from Soviet bombs, they in fact discovered gamma ray bursts - radiation from deep space. Physics - Universe - Learning Points. During the Cold War, the US suspected the Soviets of testing...

We use a Hero's engine model to show how equal and opposite forces can cause propulsion. Two holes are pierced in a metal bottle and some water is added. This is suspended above a Bunsen burner, and as the water boils and leaves the...

Good techs understand the many general issues with printers misbehaving. This episode covers a lot of these issues, such as permissions, connectivity (physical/wireless and configuration errors), and mechanical issues.

NASA is reworking an old concept, the propeller, to make air travel more fuel efficient. The prop fan, with its unique blade design, has the potential to burn 50 to 60% less fuel than present day jets. This innovation could save the...

Astrophysicist Scott Tremaine (Institute for Advanced Study) describes the intriguing relationship between galaxies and the enormous black holes at their cores.

Scientists believe there are oceans buried under thick crusts of ice on the moons of Saturn and Jupiter. Sampling them would raise hope of life beyond Earth

When it comes to defence, some countries are just safer than others. From nations with massive militaries to states with unavailable terrain, we're counting down the 10 Countries That Would Be Impossible To Invade.

Almost everything you could want to know about Saturn's sixth largest moon, Enceladus.

On Sept. 22, 2017, the National Science Foundation's IceCube Neutrino Observatory alerted the international astronomy community that a high-energy neutrino had passed through the Earth. That notification set in motion follow-on...

Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as...

A feature from NASA’s Ames Research Center in Silicon Valley originally posted on December 8, 2016.

Freeze rays, invisible tanks and nanobots. These may sound like they belong in a sci-fi movie or a Bond villain's shopping list. But they're all real technologies being worked on right now. To know more about these weapons and more:...

You should already know that speed is a...

Kristine Kirkby is a raptor biologist and works on the falconry team at Vancouver International Airport. In an amazing partnership between human and bird, Kristine gets to pursue her passion and work together with wildlife, in order to...

Chinese Su-30 fighter jets briefly entered Taiwanese airspace hours after the country’s defense ministry announced the dates of annual military exercises that test its capabilities to ward off a Chinese invasion.

Active galaxies called blazars make up the largest class of objects detected by Fermi's Large Area Telescope (LAT). Massive black holes in the hearts of these galaxies fire particle jets in our direction. Fermi team member Elizabeth...

The US military is preparing for what could happen if China launches military strikes to take out its major runway facilities in the Pacific region.

Centaurus A is a giant elliptical active galaxy 12 million light years away. Radio and X-ray images reveal features associated with jets emanating from near the galaxy's central supermassive black hole, which has a mass of 55 million...

At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and...
