Happy Earth Day! 🌎 🌍 🌏
To mark this special day, we’re tuning in to Sen, the world’s first continuous 4K video livestream from space.
Sen’s cameras are hosted on our Columbus module of the ISS, with data delivered via the Airbus platform.
Watch Earth from above, just like an astronaut

🚨 Voyager 1 now only has two instruments still operating
• One that listens to plasma waves and one that measures magnetic fields — the rest have been turned off to conserve power
• It's been flying through space for almost 49 years
I just finished watching Gorilla Story on Netflix. David Attenborough's latest documentary and it's splendid. Hard to believe he turns 100 years old in just three weeks. What a magnificent gift to conservation and humanity he continues to be. I highly recommend 10/10.

I don’t know who needs to hear this, but you’re under absolutely no obligation to justify yourself to anyone if you choose to spend the entire weekend reading a good book, making multiple cups of tea, and indulging in a borderline scandalous amount of cinnamon rolls.
Viktor Orbán created the global blueprint for authoritarian populism and became a MAGA hero. Today, Hungarian voters sent him packing after 16 years in power.
There is nothing inevitable about these guys. Organize. Vote. Fight back. It works.
ARTEMIS II: SPLASHDOWN! Welcome home, astronauts!

something strange and horrible and somehow fitting that we should have a very real threat of madman civilizational destruction at the very moment when we also have humans on the dark side of the moon taking pictures that show how small, precious, and beautiful our world and existence is
Nothing is more exciting as a neutral than watching a side let off the leash, playing fast, attacking footy & growing in confidence. That's Melbourne right now, and I'm absolutely loving watching them play. Hats off to Steven King and co., it's great to watch! #afldeessuns
Avery Brooks as Cpt. Benjamin Sisko in "Star Trek: Deep Space Nine."
In 1993, "Star Trek: Deep Space Nine" made a Black man the star of a major sci-fi franchise and his character was like the Platonic ideal of a loving father, a great cook, a man who uplifted others, who was kind and tolerant but MILITANTLY so, and who also had flaws like any other human. Hail Sisko
In the words of Carl Sagan
Turned out to be a tale of 2 halves..
Dees making a bad habit of this..
Delighted with the eventual win, but why do we make it so hard! #aflbluesdees
View from below of the massive black cylinder of the LSST Camera pointed horizontally attached to Rubin's telescope. Text reads "One year ago this month, the LSST Camera was installed at NSF–DOE Rubin Observatory. Here are 7 things to know about it! Hace justo un año, en este mes, se instaló la Cámara LSST en el Observatorio Rubin de NSF–DOE. ¡Aquí tienes 7 cosas que debes saber sobre ella!"
A person in a head to toe white suit and blue latex gloves points a flashlight into the lens end of the massive LSST Camera, which is as tall as the person. Text reads "It's enormous. Es gigantesca. Built at SLAC National Accelerator Laboratory, the LSST Camera is the largest digital camera in the world* - it's about the size of a small car and weighs roughly 3 metric tons (6,600 pounds). Construida en el Laboratorio Nacional del Acelerador SLAC, la Cámara LSST es la cámara digital más grande del mundo*: tiene proximadamente el tamaño de un auto pequeño y pesa unas 3 toneladas métricas. *It even has a Guinness World Record! / ¡Incluso tiene un récord mundial Guinness!"
A graphic showing LSST Camera's field of view on the sky, with seven full moons filling the width. Text reads "It sees a huge area of sky at one time. Puede observar una enorme porción del cielo de una sola vez. Each image covers an area about 45 times the size of the full Moon, enabling Rubin to cover the entire visible sky every few nights. Cada imagen cubre un área de unas 45 veces el tamaño de la Luna llena, lo que permite a Rubin mapear todo el cielo visible en unas pocas noches."
View straight into the lens end of the massive LSST Camera, showing a mosaic of ~200 CCD chips in a roughly square shape. Text reads "Everything about the camera is huge, including the images it takes! Todo en esta cámara es enorme,¡incluyendo sus imágenes! A single LSST Camera image is about 3200 megapixels. Una sola imagen tomada por de la Cámara LSST tiene unos 3.200 megapíxeles."
A year ago this month, our 3200-megapixel LSST Camera was installed! 🔭🧪
Here's what to know about it!
1️⃣ It's enormous!
2️⃣ It sees a huge area of sky at one time
3️⃣ Everything about it is huge, including the images it takes

Mark Hamill as Luke Skywalker on the first day of shooting.
50 years ago today, @markhamillofficial.bsky.social was preparing to film his first scene in a small film called Star Wars. Before the first lines were spoken, this photo was taken in... a galaxy far far away.
Han Solo spotted on Mercury!
He will not be permanently damaged.

Vaccines were once so uncontroversial that McDonald’s restaurants put the childhood immunization schedule on their tray liners.
Now, as the U.S. government sows doubt, preventable diseases could come roaring back.
If I’m going to be carding every single customer without checking whether they’re home anyway, then I may as well get the cards done first,” he explained.

A French general said joining Donald Trump’s war is like buying a discounted ticket for the Titanic after it hit the iceberg. Trump has had a chastening week, as the UK, France, Japan, Germany, South Korea, and even China rejected military support.

Surgeons have always been REAL Superheroes, but now they can be Spider-Man as well. 🕷️✨
Oxford researchers are using Golden Orb Spider Silk to bridge massive nerve gaps - upto 20cm in some proven cases and possibly upto 80cm 🙏
It is restoring movement once thought lost forever.

A digitally restored, archival composite image celebrating Rosalind Franklin. On the left is a black and white portrait of the British chemist and X-ray crystallographer. She has dark, softly curled hair and is wearing a dark, tailored dress, looking thoughtfully off-camera with a focused expression. On the right side is a clear, highly enhanced reproduction of 'Photograph 51'. This is her famous X-ray diffraction image of crystallized DNA fibers. The scientific image features a dark circular background with a distinct, striking arrangement of fuzzy black spots forming a perfect 'X' shape converging in the center. The heavy dark smudges at the very top and bottom of the circle indicate the repeating bases of the genetic code. The specific angle of the 'X' physically proves the double-helix structure of the DNA molecule. At the bottom, a professional credit line reads: King's College London and Seriously Scientific.
Remembering Rosalind Franklin on International Women's Day!
Without her mastery of X-ray crystallography and the iconic 'Photo 51', discovering the DNA double helix would have been impossible.
She measured the secret of life. Her exact math made gene editing possible! 🔬🧬

Today is #WorldWildlifeDay and I have been fortunate to experience so many magic moments with wildlife. We need to continue to work towards protecting wildlife and the places that they call home.
His Doctors may have applied a topical cream to his neck to treat skin cancers perhaps?
They cause blistering similar to this?
Just a guess 🤷♀️
☀️🌑🛰️ 2026: The year we arrive at Mercury!
After almost 8 years since its launch in 2018, BepiColombo is entering its most critical phase yet. It is about to end its interplanetary phase and initiate its Mercury approach.
Saja, looking rather proud about the amount of poop he can produce.
It's genuinely remarkable to me how much poop this one small creature can produce in such a short time
