Damn, the college at my university really wrote a press release about my Price award but blurred out the text ‘ I can’t breathe’ on one of the images I provided without my permission before publishing it. pic.twitter.com/oHfU02T5KD

You can measure the speed of light at home using just a microwave and a bar of chocolate! pic.twitter.com/9kyZM45uNY

Something to consider as you read about the big Venus news today: there is an unfortunate disconnect between what we do as scientists and how "science" is communicated to everyone.

A thread.
A espetacular descoberta de fosfina na atmosfera de Vênus, e a possível associação com vida nesse planeta, tem uma contribuição importantíssima de mulheres astrônomas: foi liderada por Jane Greaves (Cardiff; esquerda) e com participação da Profa. Sara Seager (MIT; direita). pic.twitter.com/opvXXdNWsI

Si usted creía que el 2020 no se podía poner más interesante, hoy se publicó un estudio en la revista @NatureAstronomy donde se reporta la detección de un posible biomarcador en la atmósfera del planeta #Venus. Y esto qué tiene de interesante? En #ElDesparche se lo contamos. 1/ pic.twitter.com/vOAqqyJJrs

While todays announcement is super exciting, I think it's really important to not go around shouting "We found life on Venus". It's difficult to explain how you get phosphine without a biological source. This is NOT the same as saying "phosphine 100% indicates life"

Que 2020 vai entrar para a história nós já sabíamos, agora quem poderia imaginar que este seria o ano em que talvez finalmente encontramos os ETs? Segue o fio desta #AstroThreadBr para saber mais sobre essa polêmica descoberta científica em #Vênus! pic.twitter.com/NWDv4O4rkr

I don't know who needs to hear this, but sometimes asteroids just crumble and fall apart, so it's OK if you do, too. pic.twitter.com/11ks6bcr3w

We found the gas phosphine in the upper atmosphere. There is no known way this can be produced by normal chemical processes by lightening, volcanoes or asteroid impact in Venus. Life can & does produce it on Earth. So we have found evidence for unusual chemistry or maybe life.

I have requested that the original image be used or that the article be removed. I hope this was not done with malicious intent. But I would rather not be praised if it is not all of me that is being praised.

Some very exciting hot takes from the press conference:

1. We only see Phosphine signatures on Venus near the equator (not at the poles), which agress with previous atmospheric theories of where microorganisms should be in the atmosphere (Hadley cells)
Things have quietened enough that I'm going to share my thoughts about the detection of #phosphine on #Venus announced yesterday.

In short: this is a BIG fucking deal. And here's why:

Como geólogo planetario y astrobiólogo estudio la Naturaleza, el Universo y la vida y su búsqueda fuera de la Tierra. Es crucial y ético precisar que, hasta el momento, no se ha encontrado vida, ni huellas de ella, en Venus, Marte, Titán meteoritos,TRAPPIST-1 ni ningún otro lugar

I have received an apology about the modification of the image and that the original image will now be used. I’m told the change was not done with any offensive intent but I think it is a lesson learned. Words mean things. Ask permission first!
— Carl E. Fields (@carlnotsagan) September 18, 2020
But therein lies the disconnect: despite what many think, science doesn't provide THE answers - it never has - it provides *an* answer, and a temporary one at that, that may be falsified later. There is inherent uncertainty and skepticism.

Dunque: è stata osservata la molecola di fosfina (PH3) nell’atmosfera di Venere. Secondo gli autori dello studio, non esistono processi chimici noti, al momento che possano spiegare l’osservazione. Il che lascia due possibilità: processi chimici sconosciuti, o attività biologica.

Y quién soy yo y porqué les hablo de esto? Los invito a leer un poco sobre mi trabajo estudiando atmósferas de planetas fuera de nuestro Sistema Solar! #MásMujeresMejorCiencia#ElDesparche https://t.co/roTecgpRkT

If you remove the turntable, the standing wave will heat up certain spots of the chocolate, at half the wavelength. If you measure the distance, double to get the wavelength, and get the frequency from the microwave, you can calculate the speed of light (to 98% accuracy!)
