40 years to the day since Ireland's greatest-ever rock'n roll star left us for the great gig in the sky. He set our musical world alight in the previous decades, putting Ireland on the musical map like no other.

At 5.15pm GMT today, the Earth will be at perihelion, the closest point to the Sun in our annual round.

This should be the start of the year. Happy new orbit, everyone!

European Space Agency hit again as cybercrims claim 200 GB data up for sale
As in past incidents, ESA says the impact was limited to external systems The European Space Agency has suffered yet another security incident and, in keeping with past practice, says the impact is limited. Meanwhile, miscreants boast that they've made off with a trove of data, including what they claim are confidential documents, credentials, and source code.…

Our XMM-Newton has observed comet 3I/ATLAS in X-ray light!

When gas molecules streaming from a comet collide with the solar wind they produce X-rays, seen here as the red glow of 3I/ATLAS 👉 www.esa.int/ESA_Multimed...

Blue marks empty space with little X-rays. The black line is a detector gap 🔭 🧪
This image shows an X-ray view of interstellar comet 3I ATLAS, captured by ESA’s XMM-Newton spacecraft. At the centre of the image, a bright red spot stands out against a dark background, like a fiery beacon. Starting from this core, faint gradients of purple and blue spread outward, creating a slightly rotated rectangular frame, divided by a thin horizontal line. The red colour shows low-energy X-rays, blue marks empty space with very few X-rays. A yellow arrow labelled “Sun” points left, indicating the comet’s orientation in the Solar System. At the bottom right, a scale marker reads “5 arcmin”, providing a sense of spatial dimension.]

The XRISM satellite has detected the x-ray glow of Comet 3I/ATLAS. This is the first time anyone has managed to obseve x-ray emission from an interstellar comet!

(FYI: X-rays result from the comet interacting with the solar wind. No spaceships required.) 🔭🧪

X-ray image of the comet captured by the soft X-ray imaging telescope Xtend. The image is created from quick-look processed data. The Xtend field of view covers a region of about 3 million km2, revealing a faint emission structure extending about 400,000 km around the comet. (Credit: JAXA)

Welcome, Plato! 🤗

On 1 September, the spacecraft arrived in the Netherlands by boat from Germany via the Rhine River.

In the coming weeks, engineers will add the sunshield & solar arrays and carry out tests to confirm Plato is ready for launch 🚀

A large cargo ship named VAARWEL, painted in blue and white, is sailing through a canal. The ship has a flag at its front and is passing under an open drawbridge in the background. The canal is lined with trees on both sides, and the sky above is bright blue with scattered white clouds. A few people are visible on the bridge and near the water’s edge. In the foreground, at the bottom right, a small boat with a single person inside floats near the ship. A large green truck from Kübler Spedition is transporting a massive container wrapped in a protective tarp. The container displays several logos and text, including the logo of the European Space Agency (ESA), indicating it is part of a specialised transport operation. In the background, there is an industrial building with large metal silos under a blue sky. In a cleanroom environment, two individuals wearing blue lab coats and hairnets are working around a large spacecraft. The spacecraft is covered in protective plastic sheeting and mounted on a white transport platform labelled with technical instructions. In a cleanroom environment, a group of engineers wearing protective coats, gloves, and face masks are working on a large spacecraft component. The component is mounted on a white wheeled platform. The top of the spacecraft carries 26 cylindrical cameras. The workspace is surrounded by structural supports and white fabric walls, creating a clean and controlled environment.

Highly recommend watching this very interesting documentary. I've been a python advocate since 2003 when I first tried using it in astronomy data analysis: It was still very immature at that time, no astropy (but there was PyIRAF!) but it was fun and away from IDL

After seven years, very happy to see my book about Herschel (the telescope) finally published. I did describe the big discoveries made with the telescope, but what I really wanted to was capture the crazy stories behind the discoveries. This is not the sanitised version of astromy. #popularastronomy

🚨 Interstellar news!

☄️ The unexpected comet 3I/ATLAS has been captured in the sharpest picture yet by the NASA/ESA Hubble Space Telescope.

Discover more about this visitor from outside our Solar System 👉 www.esa.int/ESA_Multimed... 🔭 🧪
At the centre of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the comet’s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. About a dozen short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.

To search for Earth-like planets our Plato mission will use 26 cameras in a design inspired by the compound eyes of insects.

The mission will spot any slight dimming or brightening of a star when a planet passes in front of it.

Learn more about Plato's 'eye' 👉 www.esa.int/Science_Expl... 🔭
In the photo three people in white overalls and caps stand in front of the instrumentation in a white hall. The equipment, about twice as tall as the people in the picture, consists of a black four-stepped-platform that supports 24 cameras. These resemble cylinders flaring at the top, not unlike big ice-cream cones. Each cylinder is wrapped in black material; the top flare has a metallic finish and a white lid.

Astronomers may have just discovered the third interstellar object passing through the Solar System!

ESA’s Planetary Defenders are observing the object, provisionally known as #A11pl3Z, right now using telescopes around the world.

#ICYMI Happy summer solstice! 🌞

🌍 This year's solstice happened at exactly 04:42 CEST on 21 June, the moment the Sun reached its northernmost point in the sky.

Viewed from space, these images capture a full year of shifting light and shadow, from one June solstice to the next 🧪🔭

I suspect that fact that the vast majority of LLM users don’t seem to have received this (really very simple!) message is because the AI companies have a vested interest in us not understanding it. “ChatGPT is smart, it just makes mistakes sometimes” is much more marketable than the truth.
astrokatie.com Katie Mack @astrokatie.com · Jun 19
Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.
