Did you know that it's actually NASA/ESA/CSA James Webb Space Telescope? Even though it is often referred to as "NASA" only.
European Space Agency #ESA has contributed the NIRSpec instrument, half of the MIRI instrument, and the launch (including the payload adapter & launch site services) and has 15 scientists working at the science and operations center. #CSA, the Canadian Space Agency, has contributed the NIRISS instrument.
After crisis in interstellar space, stream of Voyager 1 data resumes. Before its computer crashed, the venerable NASA probe may have entered mysterious new region beyond the Solar System.
Ätna, Krakatau und Eyjafjallajökull können einpacken: Karl erzählt in der neuen Folge von der vulkanisch aktivsten Welt des Sonnensystems: von Jupiters Mond Io, dessen Vulkane alles in den Schatten stellen, was wir sonst kennen. Und gerade das macht ihn interessant:
Got another 1.5 hours of light last night from nearby(ish) galaxy NGC 3621 which features the recent supernova #SN2024ggi
Have now been grabbing light from this event over a few months and can see its colour/flux temporal evolution.
Caught it with VIVID’s extreme light pollution too! (VIVID is a very popular festival of light here in Sydney in which light pollution increases by several orders of magnitude!)
Fun things that can happen at a conference: tomorrow there will be a heated discussion about the correct way to remove a foreground from an extragalactic observation - the sort of life and death fights you have in astronomy 😅
But guess how many experts in the actual observation and foreground modelling are present at this conference:
ZERO.
So chairs are likely going to be thrown for nothing...
New, on @TheConversationUS:
I'm an Astrophysicist mapping the Universe with data from #ChandraXRay: Clear, sharp photos help me study energetic black holes.
Beautiful (at least to me!) last rendering of the gas temperature in an evolving simulated volume - where the frequent bubble like explosion are the combination of AGN feedback or star formation - combined with the Faraday Rotation Measure by the injected magnetic fields in the same volume.
Cool to have the same colleagues arguing about a question they already debated a year ago (conference I organised back then) , getting to the same standstill, as if they had no chance of exchanging mails in a year 🙄 #astrodon#astronomy
With two new gravitational-wave candidates on May 27, there are now 101 such likely astrophysical events in O4, the fourth observing run of the gravitational-wave detectors @LIGO, Virgo, KAGRA, and GEO600.
The researchers still need to investigate the signal candidates in more detail before characterizing and publishing them in scientific papers.
Fingers crossed that there will be 200 gravitational-wave events at the end of O4 (in February 2025).
If you haven't noticed, radio astronomers worldwide are getting very shouty at radio frequency interference (RFI - akin to light pollution) increasing.
We create these multi-billion, grand-scale projects in specifically legislated radio quiet zones away from human populations to ensure we have the best capabilities to detect the faintest signals from the furthers reaches of the cosmos.
Then along comes the RFI from satellite constellations.
