🌟 Searching for the first generations of stars

Kapteyn astronomer Else Starkenburg searches the Milky Way and nearby galaxies for some of the oldest stars we can still observe. With WEAVE and 4MOST, many more may soon be discovered.

"MOONS has captured its first light, almost one thousand objects in a single observation. No astronomy instrument has ever done this before. "
Well... except for DESI and 4MOST !?

Submitted a paper that's been almost 10 years in the making! First PIGS photometric observations early 2017, photometric survey finished in 2023, several calibrations & recalibrations, many spectroscopic follow-up observations... Almost ready for the public release! 🔭✨🐷

Trump administration plans to give ICE officers electric-shock gloves
The administration of United States President Donald Trump is planning to spend tens of millions of dollars to equip federal immigration agents with gloves capable of delivering electric shocks. According to a notice posted on Monday, the Department of Homeland Security has estimated it will invest between $10m and $20m in such gloves by the end of March 2027. Recommended Stories list of 4 items list 1 of 4Most Americans say Trump has gone too far on US immigration: Poll list 2 of 4Salvadoran man dies in ICE custody at New Jersey detention centre list 3 of 4Protesters demand answers from ICE after second man dies at Delaney Hall list 4 of 4US courts clear way for deportations of South Sudan, Myanmar nationals end of list The devices are known as the CT-G5 G.L.O.V.E., an acronym that stands for “Generate Low Output Voltage Emitter”. They are currently used by some jails and police departments. Their manufacturer, Compliant Technologies, says the gloves are used to “quickly distract with small uncomfortable electrical pulses” when applied to a person’s skin. The Department of Homeland Security indicated they would be used for “distraction and de-escalation”. A user manual states the gloves can deliver a...
