Freedom Square, Kharkiv🇺🇦

In every city and village during my humanitarian volunteer trip through Ukraine, I pause to honor the fallen. 🕯️ Today, it was Freedom Square in Kharkiv.

🇺🇦Each flag is a glimpse into a life cut short, a reminder of the cost of freedom.

🕊️ Their heroism will never be forgotten.

Heroyam Slava. Slava Ukraini. 🇺🇦

One of the most anticipated films at the Venice Film Festival is “The Voice of Hind Rajab”..

The film, draws on the audio recordings of Hind’s desperate calls as rescuers tried to reach her, premieres as filmmakers urge the festival not to stay silent on the Gaza Holocaust.

Here is a more precise but more complex proposal in the paper for the definition of a planet.

Unfortunately, the IAU in the 2024 meeting did not post the proposal ahead of time and asked the authors to present it to have a large discussion and consensus before doing anything else.

The authors state that meaningful action on the proposal does not appear likely until the next IAU General Assembly in 2027 in Rome at the earliest.

Snippet from paper about the more precise definition of a planet -

A planet is a celestial body that
(a) orbits one or more stars, brown dwarfs, or stellar remnants, and

(b) has sufficient mass to dynamically dominate the neighborhood around its orbit, i.e., m > 0.0012 (mcentral)^(5/8) a^(9/8), where m is the mass of the planetary body expressed in Earth masses, mcentral is the mass of the central body expressed is solar masses, and a is the semimajor axis expressed in astronomical units, and

(c) has sufficient mass for its self-gravity to overcome rigid body forces so that it is approximately in hydrostatic equilibrium and assumes a nearly triaxial shape, i.e., m > 10^21 kg, and

(d) has a true mass below the limiting mass for thermonuclear fusion of deuterium (currently calculated to be 13 Jupiter masses for objects of solar metallicity), and

(e) has a mass ratio with the central object below the L4/L5 instability, i.e., m/mcentral < 2/(25 + √621) ≃ 1/25.

A satellite is a celestial body that orbits a planet.

@AkaSci I always felt at the time that these seemingly-arbitrary "limits" were made specifically to exclude Pluto from Planethood.😭
#neverforget

Today we remember the over 500,000 Roma and Sinti murdered during WWII. We must honour them by investing in initiatives that preserve their memory and support the communities to tell their own history. We must #NeverForget & work together to build a better future. #RomaHolocaust

🇺🇦 Kherson, this is for you.

📦I just mailed a package of CAT-7 tourniquets, a U.S. flag🇺🇸, and a card honoring my friend Oleg—a humanitarian volunteer killed while delivering aid. Since 2022, I’ve stood with the people of Ukraine. That promise continues.

You are not forgotten.🕊️

Slava Ukraini 🇺🇦
