Is dit een oplossing voor het Fermi probleem (‘where are they?’)?
According Zaza Osmanov the Fermi paradox (where are the aliens?) could be explained by Von Neumann tiny micro-probes: aliens could send out micro self-replicating spacecrafts to visit the galaxy: https://t.co/Dig75NlgiV. Concept art: Mark Molnar – https://t.co/XpU02rDd0W pic.twitter.com/m7tFfuxCkS

Garbriela Gonzáles legt uit hoe het nou precies zit met die ‘chirp’ van de allereerste zwaartekrachtgolf die door LIGO is gedetecteerd. Goede presentatie!

Een tweet over slapen in de ruimte. Yep, ook astronauten moeten slapen.
Sleeping in space is an important part of a mission, with impacts on the health, capabilities and morale of astronauts and it's not easy. Even the posture, due to micro gravity, ends up by looking totally unnatural as shown in this Shuttle footage [gif: https://t.co/PhyzkVQXzf] pic.twitter.com/vvZbuZH6WT

De kern van de interstellaire komeet Borisov blijkt roodachtig en stofig te zijn en pakweg 1 km groot.
Initial studies show interstellar Comet Borisov is reddish & dusty, with a nucleus about 1 km (~1/2 mile) wide. "This object appears indistinguishable from the native Solar System comets," says astronomer Piotr Guzik. https://t.co/6JPtSVhBee pic.twitter.com/qz3CpeORpi

De massa van het Higgs boson is met een nog niet geëvenaarde precisie gemeten.
"125.35 GeV with a precision of 0.15 GeV, or about 0.1%." Excellent work, @CMSExperiment! These measurements are very important so it is great to see them come out. https://t.co/9ahTHbyC04
