Goodbye amateur astronomy.

Goodbye amateur astrophotography.
Goodbye ground-based professional astronomy.
Goodbye transient astronomy.
Goodbye radio astronomy.
Goodbye astronomy? Goodbye space exploration?
Is this the start of the era of looking down, not up? https://t.co/hzx3VmWqTf

1/ Every once in a while clouds pay us an unwelcome visit at Paranal. This can ruin our observations, but on the other hand we can enjoy amazing Moon halos like this one I saw in November. Do you want to learn how these haloes form? Thread! pic.twitter.com/EbMrSXdjgp

A beleza da Ciência é que usando princípios básicos podemos explicar muitos fenômenos da Natureza. Por exemplo, o belo arco-íris nas asas do beija-flor é devido a que as asas atuam como uma rede de difração, decompondo a luz do Sol nas suas cores básicas

No calendário cósmico, onde a idade do universo (13,8 bilhões de anos) equivale a 1 ano, a espécie humana moderna (Homo sapiens) apareceu há apenas 12 min!

Big Bang (13,8 bilhões de anos): 1 Jan
Formação da Terra (4,5 bi anos): 3 Set

In case you haven’t heard, two (non-functioning) spacecraft have a 1 in 100 chance of colliding over the US tomorrow. 👀 They will pass each other within 15-30 meters. THAT IS SUPER CLOSE. Here I am standing 15 and 30m away. Now imagine me at 1000kg traveling at 15km PER SECOND. pic.twitter.com/lHUoJ6om15

This mind-blowing simulation by Jacob Kegerreis (of @durham_uni) shows how an ancient, giant impact of Uranus could've led its 98° tilt & wildly mixed up interior structure. As perhaps the least understood planet, it needs a mission! Let's support @IcyGiants #IceGiants2020 🚀 pic.twitter.com/U7Wo3SVpTE

Okay I've had lots of requests for copies of my DINOSAURS IN SPAAAAAAAAACE animation so I've put it up on my website: enjoy and use at will, it's just for demonstrating a couple facts about astronomy (AND DINOSAURS).https://t.co/DNxich4Bhf pic.twitter.com/EiqKiodGUL

Betelgeuse explodes:
— Juan Carlos Munoz (@astro_jcm) January 29, 2020
-People studying Betelgeuse: this is so bright it saturates all our instruments.
-People who need dark time: well shit.
-People doing long term scheduling at observatories: well shit.
-People doing IR observations who don't care about sky brightness: yay!
