Une plage, une digue. Au loin une forme non minérale. Deux genoux peut-être.

🌌 Scientists may have found a powerful new Space Object: 'It doesn't fit comfortably into any known category'

A bewilderingly powerful mystery object found in a nearby galaxy and only visible so far in millimeter radio wavelengths could be a brand new astrophysical object unlike anything astronomers have seen before.

ALMA's view of the bright core of NGC 4945, and inset, the compact, mystery object called Punctum.

Punctum is located in the active galaxy NGC 4945, which is a fairly close neighbor of our Milky Way galaxy, located 11 million light-years away. That's just beyond the confines of the Local Group. Yet, despite this proximity, it cannot be seen in optical or X-ray light but rather only millimeter radio wavelengths. This has only deepened the mystery, although the James Webb Space Telescope has yet to take a look at the object in near- and mid-infrared wavelengths.

⁉️What could Punctum be⁉️

Its brightness remained the same over several observations performed in 2023, meaning it is not a flare or some other kind of transitory phenomenon. Millimeter-wave radiation typically comes from cold objects such as young protoplanetary disks and interstellar molecular clouds.

👾However, very energetic phenomena such as quasars and pulsars can also produce radio waves through synchrotron radiation, where in charged particles moving at close to the speed of light spiral around magnetic field lines and radiate radio waves.👾

Shablovinskaia believes what we are seeing from Punctum is synchrotron radiation. Objects with strong polarization tend to be compact objects, because larger objects have messy magnetic fields that wash out any polarization. Perhaps that synchrotron radiation is being powered by a magnetar, which is a highly magnetic pulsar.

Phenomenal World - „same“! with Michael Fischer and Philipp Quehenberger is out today on Vinyl amd bandcamp! there will be a Vinyl version in mid september on @rockishell!
+ some live dates:
1. Oktober -> #stwst Linz + the answer is no
2. Oktober -> #punctum Prag
4. Oktober -> #
