A high mutual inclination system around KOI-134 revealed by transit timing variations - Nature Astronomy Using Kepler, this study identifies a compact multiplanetary system that is not flat, where gravitational interactions cause its planets’ periods to change by nearly a day per cycle and their orbital ...

UniSQ PhD student Emma Nabbie has a cool paper about a Kepler system showing more than 24 hr of TTVs! They show that the system can be explained by a mutually inclined (15deg) non transiting interior planet at 2:1 resonance! See paper! www.nature.com/articles/s41...

Just got an email from the Fulbright Association. As of right now, funding has been cut off to 12,500 US citizens currently abroad and and more than 7,400 foreigner scholars and students in the United States

As a former athlete & current researcher of online rumors & disinfo, today's atrocious example of the "right wing bullshit machine" in action — anchored on a truly idiotic claim from a football coach turned GOP senator about trans girls making girls sports "extinct" — enrages along both dimensions.

Secure & expand funding, end censorship & interference, defend diversity, equity, inclusion & accessibility in science

Secure & expand funding, end censorship & interference, defend diversity, equity, inclusion & accessibility in science

Here are the three goals of the March 7th #standupforscience as information is altered & removed, funding changed in ways that penalize scientists, & needed expansion in participation replaced with opportunities for less.

I saw a reel where it was stitched and this White Gen X guy asked why were Black GenXers so angry and the Black woman said "Because we grew up with you and thought you were different but you turned into your parents."

A word.

"Of course you got [achievement]. There are so few women in physics"
but when l express frustration about how there are so few women in physics it’s a “victim complex”

Just a reminder that the German courts have ordered Musk to hand over X data pertaining to the most recent German elections in regards to election interference specifically.

This needs to be covered more than it is.

It's a huge red flag.

World's darkest and clearest skies at risk from industrial megaproject On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.

The best dark sky in the world - the Atacama Desert in Chile, which hosts many @eso.org telescopes - is under threat from an industrial project. 🔭

Astronomers can sign a petition in favour of moving the planned industrial project: docs.google.com/forms/d/e/1F...
