Seeing One Example Of Merging Neutron Stars Raises Five Incredible Questions (Synopsis)

“O. Hahn and F. Strassmann have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they demonstrated the production of nuclei of barium, lanthanum, strontium, yttrium, and, more recently, of xenon and caesium. It can be shown by simple considerations … Read more

New Space Telescope, 40 Times The Power Of Hubble, To Unlock Astronomy’s Future (Synopsis)

“Hubble often takes images of distant gravitationally lensed galaxies to infer their substructure and to try to learn about early galaxies in general. For LUVOIR, we would have that same resolution for any galaxy! That’s truly revolutionary.” -John O’Meara If you were an observational astronomer, what would your dream telescope look like? It would have … Read more

Proof of ‘God playing dice with the Universe’ found in the Sun’s interior (Synopsis)

“The bedrock nature of space and time and the unification of cosmos and quantum are surely among science’s great ‘open frontiers.’ These are parts of the intellectual map where we’re still groping for the truth – where, in the fashion of ancient cartographers, we must still inscribe ‘here be dragons.’” –Martin Rees Inside the nuclear … Read more

Ask Ethan: Can Normal Stars Make Elements Heavier (And Less Stable) Than Iron? (Synopsis)

“Comrades, this man has a nice smile, but he’s got iron teeth.” -Andrei A. Gromyko When you have a star, perhaps its most defining characteristic is that it fuses lighter elements into heavier ones, releasing energy. While all stars fuse hydrogen into helium, the more massive ones will undergo helium fusion, with the most massive … Read more
