PEOPLE OF SPACE! I’m super excited to be hosting this week! We’ll be covering a bunch of topics that are near and dear to me including #space (obviously), astronomy, supernovae, radio astronomy, science communication, and MORE

But who is this random dude yelling at us about space?
Well the short version is that I’m a physicist who finished high school with every intention of becoming a lawyer - pictured is 19yo me not caring about science

What are the commonalities among these three?
1. Marxist theory of surplus-value
2. Freudian theory of Libido, aka Id
3. Lévi-Strauss theory of Structural Anthropology
You must listen and try to decipher the CBC Massey Lectures delivered by #George #Steiner back in 1974 to answer the above tweet.
I have the greatest respect for this polyglot scholar par excellence.
So was Karl #Marx and his #Hegelian Materialistic #Dialectic that explained the economic history of social #evolution using scientific processes, a by-product of #Romanticism that had swept European Intellectual and Literary Circles?

Just released @healpy 1.15.0, this is a large release with many important changes, please test and open issues at github.com/healpy/healpy/….

Thread with changes:

* New viz function `projview` based on plain matplotlib, with lon/lat labels and more healpy.readthedocs.io/en/latest/newv… Mollweide projection of a map with longitude and latitude la
* Finally new default for I/O: write_map keeps dtype of input map array instead of float32, read_map keeps dtype of FITS file instead of upcasting to float64, write_cl uses dtype of input cl instead of float64, see discussion in github.com/healpy/healpy/…
* Changed all warnings to using the logging module, deprecated all verbose keywords , see the docs healpy.readthedocs.io/en/latest/#ver…, discussion in github.com/healpy/healpy/…

A diffuse glow of high-energy gamma rays hints at the presence of powerful cosmic accelerators, called PeVatrons, within the disk of our Galaxy.

Many physicists believe that such #PeVatrons accelerate particles up to at least PeV energies (PeV=10^15 eV).

Possible PeVatrons include #supernova explosions, star-forming regions, & Sgr A* the supermassive black hole at the center of our galaxy.

But despite decades of hunting, only a few PeVatron candidates have been located in the #MilkyWay.

The Tibet ASγ experiment, a #China-#Japan collaboration, has reported new measurements that provide further evidence for galactic #PeVatrons.

🔭✨🌀 Záhada galaxie BEZ TEMNÉ HMOTY vyřešena, odsává ji galaxie jiná...

Titěrná galaxie NGC 1052-DF4 udělala nedávno v kosmologii nemalé vlny. Její pozorování naznačilo, že má kolem sebe šokantně málo temné hmoty. Nynější studie naznačuje řešení záhady – temná hmota kolem NGC 1052-DF4 skutečně chybí, ale jenom protože ji UKRADLY GALAXIE OKOLNÍ. 💥
To zjistilo pozorování týmu MIREI MONTES učiněná s pomocí Hubblea. DF4 se totiž nachází blízko masivnější galaxie NGC1035. Právě tenhle větší budulínek z menší galaxie ZŘEJMĚ ODSÁVÁ viditelnou (baryonovou) hmotu i „neviditelnou“ temnou (nebaryonovou) hmotu. 🌬
