China will attempt another mission to the far side of the moon on Friday,
the first of three planned over coming years as part of its goal to land a human on the lunar surface by 2030.
The launch of the uncrewed Chang’e-6 is expected sometime between 8.30am GMT and 11am GMT and the mission
– if successful – would go far to bolster China’s ambitions to put a man on the moon by 2030.
However the mission has also drawn concern from the US, China’s major rival, over Beiji…

Dit moesten jullie maar even lezen zoals het is, de post is te groot om te vertalen en een aantal links zijn zelfs voor mij paywalled, maar ik boost het toch. En inderdaad, ga eerst even zitten. https://aus.social/@ajsadauskas/112009009421402914

Status: getting the backyard hydroponics system ready for this year’s plants. Dropping a few varieties that didn’t grow so well, but planting again peas, various peppers, cucumbers, tomatoes, tomatillos, kohlrabi, beets, Swiss chard, a long list of spices, strawberries, lots of lettuce, and probably a bunch of other things that I forgot but will remember when I go through my seed packets.
Homegrown system. Not hard. Fun, and veeerry delicious. Documentation at

A new mass and radius determination of the ultra-short period planet K2-106b and the fluffy planet K2-106c
Ultra-short period planets have orbital periods of less than one day. Since their masses and radii can be determined to a higher precision than long-period planets, they are the preferred targets to determine the density of planets which constrains their composition. The K2-106 system is particularly interesting because it contains two planets of nearly identical masses. One is a high density USP, the other is a low-density planet that has an orbital period of 13 days. Combining the Gaia DR3 re…

Tracking the motion of a shock along a channel in the low solar corona
Shock waves are excited by coronal mass ejections (CMEs) and large-scale extreme-ultraviolet (EUV) wave fronts and can result in low-frequency radio emission under certain coronal conditions. In this work, we investigate a moving source of low-frequency radio emission as a CME and an associated EUV wave front move along a channel of a lower density, magnetic field, and Alfvén speed in the solar corona. Observations from the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory, …

Thinking about ownership semantics for a planned refactoring of libscopehal to make heavier use of C smart pointers.
Instruments obviously have to have shared references to their channels.
Channels need weak references to their parent instrument, to prevent circular dependencies.
I'm still waffling over GUI elements, but I think we want shared references in most of the GUI long term (to enable a newly added node to exist in the filter graph dialog or a properties page…

AI-powered cameras installed on Metro buses to ticket illegally parked cars
Artificial intelligence-powered cameras are being installed on Los Angeles Metro buses to help ticket cars parked in bus lanes.
Testing is planned for this summer and the program is expected to go live by the end of 2024, after two months of community outreach to “ensure that the public is aware of the purpose, timing and impacts of this new program.”

AI-powered cameras on Metro buses will help ticket parked cars
The technology from Hayden AI will help the ticketing process of vehicles parked in Metro bus lanes and at bus stops.

The death of Vulcan: NEID reveals the planet candidate orbiting HD 26965 is stellar activity
We revisit the long-studied radial velocity (RV) target HD26965 using recent observations from the NASA-NSF 'NEID' precision Doppler facility. Leveraging a suite of classical activity indicators, combined with line-by-line RV analyses, we demonstrate that the claimed 45-day signal previously identified as a planet candidate is most likely an activity-induced signal. Correlating the bulk (spectrally-averaged) RV with canonical line activity indicators confirms a multi-day 'lag' between the obser…
