So November has been quite a month already for @LIGO @ego_virgo and #GravitationalWaves – and we're only 9 days in so far!!…. What's still to come in the next 3 weeks? Watch this space(-time)! (And don't forget you can follow our #GravitationalWaves alerts on #Chirp) pic.twitter.com/l4zzmElHyE

Wowie, geen tsunami van water, maar van wolken! Ze noemen dat ook wel een Kelvin-Helmholz-achtige wolk. Heel indrukwekkend, vooral met die bliksem erbij.

Nog even ter herinnering: morgen is de transitie van Mercurius over het zonsoppervlak!
?????? Watch the skies on Mon., Nov. 11 for a rare event that only happens 13x per century: a Mercury transit, meaning that the planet passes directly between Earth and the Sun. How to observe: https://t.co/kSQlxajLdH

Mmmm, zou het misschien kunnen dat Planeet 9 al gezien is door TESS? Zou zomaar kunnen. 🙂
Could TESS have already seen Planet Nine? – A normal first reaction would be no way. These objects are far, far too faint to see. But in a new paper just published some astronomers show how it could be done. @BadAstronomer @SYFYWIRE https://t.co/K1SMsJUWTH pic.twitter.com/eCNSy7G8n5

Héél knap gedaan, een video van het ISS dat voor de maan langs gaat.

Een driedimensionaal model van de 5000 sterren die het dichtste bij de zon staan. Wie telt ze?

Stel nou dat land water was en water land. Dan zag de aarde er zo ongeveer uit.
What would Earth be like if all the land was oceans and all the oceans were land? This map by artist Sanna Dullaway showcases a planet with a sprawling landmass that extends across two-thirds of its surface. https://t.co/5TKJ4yMbrc pic.twitter.com/0r7bv0NAng

Ik had vanochtend een blog over de video van de beweging van exoplaneet 51 Eri b. Maar deze mag er ook wel zijn, ook ‘gefilmd’ met de GPI. Het betreft de exoplaneet Beta Pic b.
Beta Pic b – a planet big/young/near-enough that we can actually watch it move. And we can get photons directly from its atmosphere!
It's also the only planet with a mass from astrometry!
Plus it has transiting exo-comets, another interior planet and a dust disc! #ExoCup2019 pic.twitter.com/M456QztSxl— Hugh Osborn (@exohugh) November 3, 2019
