NASAが公開したハンドスピナーの動画よりも気になる動画

アメリカ航空宇宙局（NASA）が国際宇宙ステーション（ISS）で、ハンドスピナーを使っている動画に注目が集まっておりますが、さらに気になる動画が…。

アメリカ航空宇宙局（NASA）公式ユーチューブ（Youtube）動画や公式インスタグラム（Instagram）などから、両方の動画を。

あなたはどちらに興味があります??

ちなみに宇宙飛行士のランディー/ランドルフ・ブレスク（Randy/Randolph Bresnik）が公式インスタグラム（Instagram）やツイッター（Twitter）などに公開した動画を国際宇宙ステーション（ISS）の公式SNSアカウントやアメリカ航空宇宙局（NASA）公式SNSアカウントで拡散された。

A fidget spinner in space! How long does it spin? I'm not sure, but it’s a great way to experiment with Newton’s laws of motion! pic.twitter.com/5xIJDs2544

Fidget spinner spinning in space!

A fidget spinner in space!? How long does it spin? I'm not sure, but it’s a great way to experiment with Newton’s laws of motion! Allowing the fidget spinner to float reduces the bearing friction by permitting the rate of the central ring and outer spinner to equalize, and the whole thing spins as a unit.

Round and round they go – then BOOM! This animation begins with the final moments of two neutron stars (the super-dense cores of exploded massive stars), whirling around each other in a galaxy 130 million light-years away. Gravitational waves (rippling disturbance in space-time, shown here as pale arcs) bleed away orbital energy, causing the stars to move closer together and merge. As the stars collide, this explosive event emits light across a series of different wavelengths – first gamma rays (magenta), then ultraviolet (violet), then visible and infrared (blue-white to red) and once the jet directed toward us expanded into our view from Earth, X-rays (blue). Our Fermi Gamma-Ray Space Telescope witnessed this event on August 17, 2017 and we watched it unfold over multiple days with a variety of other telescopes, including the Swift spacecraft, the Hubble Space Telescope (@NASAHubble), the Spitzer Space Telescope, our Chandra X-Ray Observatory (@NASAChandraXray) and our NuSTAR mission. The detectors at the Laser Interferometer Gravitational-Wave Observatory (LIGO) received a gravitational wave signal just 1.7 seconds before the first light was seen by Fermi, making this the first event observed in both light and gravitational waves.
