When I was a kid I remember being a member of Ms. Frizzle’s classroom. We went on adventures under the ocean, into the rainforest, out to the stars, and even to the center of the Earth and it was amazing.

Of course I am talking about my time on the Magic School Bus.

A relic of the nineties, the Magic School Bus starred Lily Tomlin as Ms. Frizzle, an eccentric teacher who owned a magic school bus that she used to take her students on fantastical journeys. The show and subsequent video games were a big part of my, and thousands of other children of the nineties’, formative years as it presented educational topics in an engaging way that made you curious to learn more.

The Milky Way and hundreds of galaxies surrounding it are being drawn toward a mysterious force scientists call the “Great Attractor”.

And it took the Commonwealth Scientific and Industrial Research Organisation’s (CSIRO) Parkes telescope to see them.

The force was first revealed back in the 1970s, when it was discovered that the Milky Way was one of hundreds of galaxies deviating from the “universe is expanding” model.

The scale of the universe (HD)

Published on Sep 23, 2015.

Carl Sagan told us that there are more stars in the universe than there are grains of sand on all of the Earth’s beaches. At the same time, there are more H2O molecules in just 10 drops of water than there are stars.

Ranging from the unimaginably small to the unimaginably big, the scale of the universe is mind-boggling. Watch to try to wrap your head around it.

NASA laser expert Mike Krainak and his team plan to replace portions of this fiber-optic receiver with an integrated-photonic circuit (its size will be similar to the chip he is holding) and will test the advanced modem on the International Space Station. (credit: W. Hrybyk/NASA)

A NASA team plans to build the first integrated-photonics modem, using an emerging, potentially revolutionary technology that could transform everything from telecommunications, medical imaging, advanced manufacturing to national defense.

The cell phone-sized device incorporates optics-based functions, such as lasers, switches, and fiber-optic wires, onto a microchip similar to an integrated circuit found in all electronics hardware.

The device will be tested aboard the International Space Station beginning in 2020 as part of NASA’s multi-year Laser Communications Relay Demonstration (LCRD). The Integrated LCRD LEO (Low-Earth Orbit) User Modem and Amplifier (ILLUMA) will serve as a low-Earth-orbit terminal for NASA’s LCRD, demonstrating another capability for high-speed, laser-based communications.

The Xeelee had to build their damned ring SOMEWHERE…

The “Xeelee Sequence” novels. by Stephen Baxter, are some of the best hard science fiction ever written. If you haven’t read them, do so. Immediately. In the meantime (even if you’ve already read the entire Xeelee series) check out this atmospheric musical composition by Oliver Lugg, inspired by the above mentioned science fiction series. It’s quite beautiful: https://www.youtube.com/watch?v=TiYxHpGmPwQ


Astronomers just uncovered hundreds of hidden galaxies a mere 250 million light years away from Earth—well within our own galactic neighborhood. But how did they stay unknown for so long? The fault isn’t with them, it’s with our own Milky Way.

The International Centre for Radio Astronomy Research just completed a survey, published today in the Astronomical Journal, detailing the hundreds of newly discovered galaxies—as well as giving a much better idea of where some older suspected galaxies were hiding. Altogether, they mapped 883 galaxies lurking behind the Milky Way; you can see an artist’s representation above.

Scientists had some idea that there was something out there — but they didn’t know what. Some of the brightest clusters of galaxies were already visible, an even better clue, though, was a strange gravitational force pulling the Milky Way towards it.
