I’m at @issibern.ch this week! 😎

An intl. team has gathered to discuss all things SPIN about stellar mass black holes. I haven’t met most of the team before, so excited to form new collaborations!

Photo taken from a plane window during sunset, showing the aircraft wing and a iPad screen playing a livestream of Artemis 2 astronauts inside their spacecraft. Text on the image says, “Me: 11 km above the Earth. Them: 406,740 km above the Earth,” capturing the feeling of watching the Artemis lunar flyby while flying on a plane.

Was GLUED to the livestream of the lunar flyby while on a 10hr flight ✈️

These brave astronauts will be home soon.
Integrity, you’ve got this! 💪

A promotional poster for the “Glorious Women Symposium” (5–6 March 2026), hosted by LIGO-India Education & Public Outreach and the Inter-University Centre for Astronomy and Astrophysics (IUCAA), with the LIGO India and IUCAA logos at the top. The poster highlights contributions from women scientists in gravitational-wave astronomy and lists program items: eminent speakers from the global collaboration, focus sessions on multidisciplinary GW science, a panel discussion on women representation in GW science, and an interaction session “Ask a Woman GW Scientist.” It notes the event is free, online, and open to all, includes a QR code for registration/details, and lists organisers; the main graphic is a side-profile silhouette filled with illustrations of diverse women.

It’s been 10 years since the discovery of GWs was announced to the world! ✨

It’s also Intl Day of Women & Girls in Sci 💜

Here’s something to celebrate both—a symposium ft. women in GW science! 👩‍💻

LIGO Detected Gravitational Waves from Black Holes On September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC), the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Wash...

The @ligo.org and @egovirgo.bsky.social collaborations officially announced the first direct detection of gravitational waves #OTD in 2016.

Hard to believe we are ten (ten!) years into the gravitational wave era of astronomy and astrophysics. A remarkable tool for understanding our Universe. 🧪 🔭 ⚛️

OTD 10 years ago, LIGO detected gravitational waves for the first time.

We asked 6 women in science the best advice they've received! 👏 YouTube video by European Space Agency, ESA

Seven women. Seven careers. Seven pieces of advice.

For #InternationalDayOfWomenAndGirlsInScience we’re celebrating the voices and wisdom of women shaping science and technology across Europe. #IDWGS #WomenInSTEM

LIGO Detects Gravitational Waves from Merging Black Holes Illustration Credit: LIGO, NSF, Aurore Simonnet (Sonoma State U.) Explanation: Gravitational radiation has been directly detected. The first-ever detection was made by both facilities of the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Washington and Louisiana simultaneously last September. After numerous consistency checks, the resulting 5-sigma discovery was published today. The measured gravitational waves match those expected from two large black holes merging after a death spiral in a distant galaxy, with the resulting new black hole momentarily vibrating in a rapid ringdown. A phenomenon predicted by Einstein, the historic discovery confirms a cornerstone of humanity's understanding of gravity and basic physics. It is also the most direct detection of black holes ever. The featured illustration depicts the two merging black holes with the signal strength of the two detectors over 0.3 seconds superimposed across the bottom. Expected future detections by Advanced LIGO and other gravitational wave detectors may not only confirm the spectacular nature of this measurement but hold tremendous promise of giving humanity a new way to see and explore our universe.

It’s amazing that the field of gravitational wave astronomy is only 10 years old and yet so rich with science & discovery💡✨

Here’s to the next 10 years! 🥂

Woman, 69, in hospital with four broken vertebrae after interaction with police at Sydney Herzog protest Jann Alhafny says she feared there could be a stampede or that she might suffocate after she was allegedly pushed to the ground Punched, pepper sprayed, charged: police accused of brutality at Sydney protests – Full Story podcast Get our breaking news email, free app or daily news podcast

"Interaction with police" holy hell

www.theguardian.com/australia-ne...

I am absolutely disgusted.

The police used excessive force. And even so, PEOPLE HAVE THE RIGHT TO PROTEST! Police were throwing around folks that were peacefully protesting!

Shame on you NSW Police, and Chris Minns for defending these actions.

Dozens arrested as violence mars Sydney rally against Herzog visit Thousands of people attend protests across the country against Israeli President Isaac Herzog's visit to Australia in the wake of the Bondi terror attack, with demonstrators in Sydney sprayed with pep...

There’s going to be a whole lot of politicians and high-level officials in front of the cameras today after the really disturbing and disgusting behaviour of the Police at yesterday’s protests.

I dunno, but inviting a guy who signs his name on bombs, is gonna kinda trigger people 🤷🏼‍♂️

I'll use this as an opportunity to re-share my space artists starter pack. Several of them take commissions and have worked on images for scientific press releases before. Astronomer colleagues, I encourage you to work with real artists for press releases for important results!

What a mess! 😵‍💫

Haha… hahaha… ha…

I have no words…

Finally made it to 2026! ✨

What’s the year been like so far folks? 🤣

Breaking: PM announces 'largest' gun buyback scheme since Howard era Prime Minister Anthony Albanese has announced a national gun buyback scheme, days after a deadly terror attack on a Hanukkah celebration.

Within a week of the tragic and terrorist events that targeted the Jewish community here in Sydney, the Australian Prime Minister has announced a gun buy-back scheme to get guns off our streets.

This is just one action item, there are more in the works (like license regulations, max caps, etc.)

A good objective for all of us to see how low this number can get if we really put some effort in. We got a factor of two after Port Arthur — I’d want to see at least an order of magnitude now

What is the best black hole? 🤔

I spent my Thursday night having a very unserious debate with some colleagues at @ozgrav.bsky.social about this.

My vote? Cygnus X-1 🖤

And here’s why. I DARE you to disagree 🔥

(this debate was totally worth hopping on a call at 9pm)

#BlackHoles #Research

Don’t let the folks who named GW events in this debate hear you!

And for the reveal… I picked Cyg X-1 🖤

The icon. The first candidate. ✨

I think some folks missed the memo and named gravitational wave events. Like hang on folks, this is about the best black hole, not the best black hole pair 🤣
