The “Eye of Sauron” spotted in deep space

👁️ Okay, so the plasma jet in the blazar PKS 1424+240 isn't on a tower in Mordor, and it's not the fire-rimmed eye of a powerful tyrant. But if you don't think of Sauron's eye when you see the image released today, throw the first ring.

📡 Behind this deep image of the jet at unparalleled resolution are 15 years of ultra-precise radio observations with the Very Long Baseline Array (VLBA) and an international research team.

Curious? Please take a look at our latest press release:

Das „Auge von Sauron“ im Weltraum entdeckt!

👁️ Zugegeben, der Plasmastrahl im Blazar PKS 1424+240 befindet ich nicht auf einem Turm in Mordor und es handelt sich auch nicht um ein von Feuer umrandetes Sehorgan eines mächtigen Herrschers. Doch wer bei dem heute veröffentlichten Bild nicht an Saurons Auge denken muss, der werfe den ersten Ring.

📡 Hinter diesem detaillierten Bild des Jets mit der bislang besten Auflösung stecken 15 Jahre ultrapräziser Radiobeobachtungen mit dem Very Long Baseline Array (VLBA) und ein internationales Forschungsteam.

NASA Voyager 1 is now at 23,837,974,000 km of distance from Earth and we can't see it.

However, its radio signal can be seen. This is how @TheNRAO #VLBA saw it exactly 10 years ago #Today

Don't forget: tomorrow, 1 February, is the deadline for the #NRAO
Semester 2023B Call for Proposals! If you want time on the #VLA or the #VLBA, get your proposals in by 22:00 UT (5pm ET).

I get an email every time a proposal comes in, so I'm expecting a full inbox tomorrow!

A new image of Tycho's crater on the Moon is the most detailed yet captured from Earth.

The inner structure of the jet of the nearby #quasar 3C 273 – the region where the jet is shaped – is revealed by very long baseline interferometry (#VLBI) observations at 3mm with #ALMA, and the Global Millimetre VLBI Array (#GMVA, consisting of the US Very Long Baseline Array (#VLBA) and European #telescopes).
