Cosmographer at University Paris-Saclay | co-discoverer of Laniakea (our home supercluster), Ho'oleilana, and some other (very) large scale structures 🌌 🔭 💻
Paris+Saclay, ラニアケア超銀河団
Joined May 2012
Discovery alert! A spherical shell-like structure 1 billion light-years in diameter named Ho’oleilana is discovered in the distribution of relatively nearby galaxies. We posit this is the 1st observation of an individual Baryon Acoustic Oscillation (BAO). https://t.co/0fFuH7JeVH

Happy birthday to Whoopi Goldberg. Fun fact: Goldberg joined TNG as Guinan after telling Gene Roddenberry she had to be on the show because seeing Nichelle Nichols as Uhura showed her a Black woman could be in the future. The role of Guinan was created specifically for her.

It's extremely sad that the wider public doesn't know that she signed her name, always, as Skłodowska-Curie. Her Nobel prize carries that name, and she was very proud of her Polish heritage, (See: Polonium) . A lot of post death French whitewashing has gone into burying it.
