Very cool, just out on #astroph

"XRISM forecast for the Coma cluster: stormy, with a steep power spectrum" by the XRISM collaboration.
arxiv.org/pdf/2504.20928
in which they report the first analysis of X-ray doppler broadening with resolved spectral observations of the centre of the Coma cluster - theoretically a prototype of clusters with dynamical activities and non-thermal emission: the results are quite away from expectations!

A project I have been working on got its official release today.

Space images are pretty, but would you like to know what the important features are, and the science behind their appearance? ViewSpace Interactive Image Tours take you on a guided exploration of astronomical images.

Designed to be used on touch screens in museums and science centers, they are also fun to explore on your own. They work best on tablets or computers (devices bigger than a phone).

Three astronomical objects, each represented as a cutout image separated by diagonal lines. The left cutout shows a colorful field of dust and gases. One ridge of dust and gas is outlined with a dotted green line. Slightly below the outline, a bright red light is circled with a dotted green line. Three dotted green arrows point from the circled red light toward the outlined ridge. The central cutout shows one arm of a spiral galaxy. The spiral arm, a thick filament of dust and gas, begins near a bright yellow core and swirls outward, clockwise. There are pockets of pink, which are star-forming regions. All other details within the region are covered with a darkened overlay. The right cutout shows two jets of hot gas shooting out from central stars.  There is a white dashed line outlining a thick line of soft brown dust and gas, which is the edge of the nebula. This edge and its outline stretch from the bottom left of the cutout to the bottom-center before curving upward and ending at the top-right.

Moon RACER Activates Self-Driving Mode for Lunar Exploration

On a rugged mock moonscape, the Moon RACER team demonstrated its terrestrial Lunar Terrain Vehicle mock-up’s ability to autonomously navigate using advanced LiDAR and perception software.

Let's take a peek inside one of the ALMA antennas! 📡⁠
⁠
The 66 antennas of ALMA are all used to observe the cool Universe. But how does a radio-telescope really ‘see’? 🤔⁠
⁠
First, light is collected by the large dish of an antenna, which is focussed onto the secondary reflector that we can see in the foreground. From there, it goes through one of the several circular windows seen at the centre of this image. Each window leads to a receiver, a device that registers the light collected by the antenna. ⁠
⁠
And did you know? The receivers need to be sealed inside a cryostat that cools them down to –269 ºC, just 4 degrees above absolute zero 🥶⁠

The image is a close up of one the ALMA antennas. In the centre left foreground of the image, is a circular structure held by four support beams that continue outside of the boundaries of the image. In the background is the grey dish made up screwed on panels. To the bottom right in the background is a hole for the receiver cabin, filled with circular and rectangular instruments on a blue plate.

China wants to launch its lunar probe Chang'e 8 in 2028/29. Remarkable for such a developed national lunar research programme: Its large number of international collaborations, mostly with countries from the global south:

Before Easter, I was honoured to give a colloquium to the Lviv Fellow Society (#Ukraine). I've never been there in person, but thanks to my ongoing tight collaborations in 🇺🇦 , I feel bound there and I hope I can visit soon.
To make it more attractive to the general public, I spoke of my recent extravaganza about the "Simulation Hypothesis" frontiersin.org/journals/physi

and it was fun as it sparked many new questions.

Ein sehr schöner Artikel von @sianderl:

▶️ zeit.de/2025/17/hubble-telesko

Es ist schon Irrsinn, wenn ich darüber nachdenke, wie anders die Welt war, als Hubble gestartet wurde und wo wir heute sind (gleiches gilt auch für die beiden großen Röntgenteleskope XMM-Newton und Chandra).

Einen Artikel zum 35sten Jubiläum von Hubble mit neuen spektakulären Weltraumbilder gibt es hier:
