For all the folks starting their #PhD (or their master thesis) today - a reminder why your PhD advisor can solve a problem so "easily" ...

Ahem... 📢

Dear ppl - please do not repost stuff from accounts such as "amazing science", "wonders of science/nature", etc. OR posts that use these accounts as sources.

They are spoofers, stealing artwork without attribution, often misrepresenting highly photoshopped (or fully artificial) images as real and not so seldomly posting absolutely bogus explanations.

Nature is beautiful - it does not need Photoshop or wrong explanations to make it sound more sensational.

I love passing by wind turbines. They are such an essential solarpunk element to me. Seeing one feels like a sign of hope: a different future is possible.

It's only since Cecilia Payne's PhD thesis in 1925, that we know what the stars - and our Sun - are made of: mostly hydrogen.

Her thesis was described as ""the most brilliant PhD thesis ever written in astronomy" and it extremely readable: https://ui.adsabs.harvard.edu/abs/1925PhDT.........1P/abstract

Yet It took until 1956, 10 years before her retirement, for her to become full professor - because women were barred from becoming full professors at Harvard.

(Posted because she was born #OTD).

It's mind-blowing how young some of our knowledge about the Universe is 🤯

⭐ It's only since the seminal thesis of Cecilia Payne-Gaposchkin in 1925 that we know that stars are mainly made of hydrogen & helium:

🌀 And it's just so less than 100 years ago since Hubble, building on Henrietta Swan Leavitt’s period-luminosity relation for Cepheids, has shown that our own Milky Way is just one galaxy among many:

Want to become my colleague? #ESA is looking for a planetary scientist to fill the role of the archives scientist for the planetary science archive, initially assigned to #Mars missions:

▶️ https://jobs.esa.int/job/Villanueva-de-la-Ca%C3%B1ada-Archive-Scientist/987806201/

Deadline: 18. October 2023

(OK, almost my colleague, same agency, different location - you'd be based in Villanueva de la Cañada close to Madrid, Spain, while I'm in Noordwijk, NL).

People post because they want to vent, to share their frustration, to make others laugh or shake heads. If ppl post to get advice, they usually ask.

So: You want to give advice?

Has the person explicitly asked for it? No? Then don't.

But you really, really want to give advice! Still: no!

But your advice is really relevant! Still: no.

But you also know the person well (you follow them & they you & you interacted): ask if they want advice. If they don't explicitly say yes - it's still a no.

Physics World has talked to me about my science and about all the things I do as a scientist that are not my science - climate activism and Astronomers for Planet Earth (@a4e), my art and outreach in general :)

A reminder, also to myself: if someone does not feel right, block. Block early. Block before you spend emotional energy.

It's not a public forum (except if you want it to be). It's your space. Your little corner. (Your salon if you run it like I do mine.)

If you prefer to read things instead of listening (as do I myself; not an audio person ... 😅 ), Physics World has now turned the podcast with me into a written interview:

It's about my science, but also about all the things I do as a scientist that are not my science - climate crisis outreach and Astronomers for Planet Earth, my art and outreach in general.

Want to know what my research is about? Follow this thread 🧵 based on a 10min talk I've drawn for a meeting.

The talk was aimed at non-specialist space science colleagues (not the general public!). The slides were built up step by step, but I'm omitting this here & showing only the final graphs, less this becomes a 34-part thread. 11 is plenty enough!

So: "Understanding Winds of Massive Stars Using High Mass X-ray Binaries"

Cecilia Payne-Gaposchkin, who revolutionized our understanding of what stars & the Universe are made of, was born #OTD in 1900.

In 1926, she wrote what is considered the "undoubtedly most brilliant PhD thesis ever written in astronomy".

She continued in the same spirit - only to be denied a professorship (or even the a proper astronomer position). She finally became a professor at Harvard at 1956(!) & first woman to chair a department.

Men are constantly hired because they are men. But they are oh so upset if there is even a tiny impression that the gender of a woman was part of the hiring decision 🙄

We are launching the #ESA Science Newsletter! It serves the scientific community and welcomes everyone interested in more programmatic and technical news from the Directorate of Science: calls for proposals, announcements of opportunity, research fellowship announcements, calls for memberships, job announcements, major mission updates, conference announcements, etc. for all our missions!

"Reward for measured performance in higher education is touted by its boosters as making universities 'more like a business'. But businesses have a built-in restraint on devoting too much time and money to measurement -- at some point, it cuts into profits. Ironically, since universities and other nonprofit institutions have no such bottom line, government or accrediting agencies or the universities' administrative leadership can extend metrics endlessly."

#Pulsars are magnetized, rotating neutron stars. Beams of radiation from their magnetic poles swipe past the observer, resulting in characteristic pulsing radio patterns.

The fastest pulsar we know, PSR J1748−2446ad, rotates at 716 times/sec or 43000 times/min.

You can listen to some of the pulsars here - the intensity of the radio waves as the amplitude of the audio:
▶️ https://www.jb.man.ac.uk/~pulsar/Education/Sounds/sounds.html
Not the 716 Hz one, but the 173.7 Hz (careful, annoying sound!)

1/16 This July, I gave an invited talk in the "Communicating Science Through Art" session at the European Astronomical Society annual meeting, organized by the amazing @theastrophoenix . And I thought it may be something that would also interest you #fediverse folks.

The aim of the talk was partly to give people insight into my why & how of my art. But mainly to encourage others to just try. In a very subjective manner.

Whelp ...

"Temperatures are sizzling across Europe this week amid an intense and prolonged period of heat. And it’s only just begun. Italy, Spain, France, Germany and Poland are all facing a major heatwave with temperatures expected to climb to 48°C on the islands of Sicily and Sardinia – potentially the hottest temperatures ever recorded in Europe."

I just love this image - it highlights why we need all the different telescopes: each of them looks at the same object in different ways. And only when working together a complete image emerges.

Here, #Euclid's wide field is combined with #Hubble's zoom-in and #JWST sharpest IR image we ever obtained, allowing us to study how radiation interacts with interstellar matter.
