A multiwavelength glimpse at a space oddity!

Astronomers from ICRAR have led a global team to reveal new insights into the growing population of Long-Period Transients.

What makes ASKAP J1832-0911 stand out from the rest of the Long-Period Transients is that, for the first time, coincident X-ray emission, along with radio emissions, have also been detected from such an object, thanks to the Chandra X-ray Observatory.

Now I wonder if light gets the same slingshot effect planets and stars give to objects in space. Does it speed up or slow down based on that?

My tiny brain has finally accepted the concept that, to light, the universe is crossed in a fraction of a second, due to relativity, while from our frame of reference, it has taken light perhaps billions of years, and so my cranial friend can't stop thinking of it as an excellent transmitter of data for any period in spacetime, should one feel the need to control an avatar.

Nah. We're NPCs in an infinite loop of light and dark matter caused when an alien kid in the 2nd grade neglected the semicolon at the end of a statement.

"BLORPRAX! IS THIS YOUR UNIVERSE I SEE THRASHING SO?"

"Uh... Maybe."

If light moves more slowly than space expands, wouldn't it follow that somewhere in the sky there exists light from our own galaxy in its distant past? This wouldn't be the case if we remained fixed as space expanded, but we aren't fixed in space or time (unless that's one heck of an illusion). If light is emitted into space in some direction, and the emitting galaxy is moving along the same path, it would pass its own previously emitted light, wouldn't it?

That should create an interference pattern, I think. It would keep happening. It wouldn't be a one-off. Perhaps we measure the light from galaxies a bit higher than their actual emissions because of this effect, if it's real. I wonder if it might affect spectra.

[Edit: Nope. The light might never reach us, or if it did, it traveled along a path in space moving faster than the path in space our galaxy took. Blah. Boo. Oh, well.]

I shouldn't post silly physics musings in the middle of the night. I should post them in the middle of the day, too!

If I had a time travel machine, I’d travel all the way back to the big bang and watch it just so I could tell all those highfalutin astrophysicists that I know what really happened!

Do photons wear out? An astrophysicist explains light’s ability to travel vast cosmic distances without losing energy.

CEA: Une histoire spatiale qui commence en 1959

Pour traquer les poussières radioactives liées aux essais nucléaires, le CEA embarque un compteur Geiger dans un missile. À 100 km d’altitude, surprise : des rayons gamma viennent d’au-dessus. C’est le début de l’astrophysique au CEA.

This colorful network of faint gas filaments is part of the Vela Supernova Remnant, an expanding nebula composed of debris left over from a massive star that exploded about 11,000 years ago. Captured by the Dark Energy Camera (DECam), the striking red, yellow, and blue colors in this image were.....

Using our Very Large Telescope (VLT) and ALMA, astronomers have witnessed for the first time a violent cosmic collision, in which one galaxy uses a quasar to pierce another galaxy with intense radiation.

The radiation released by the quasar disrupts the clouds of gas and dust in the other galaxy, leaving only the smallest, densest regions behind. These regions are likely too small to be capable of star formation, leaving the wounded galaxy with fewer stellar nurseries in a dramatic transformation.

The biggest difficulty I'm having is accepting Death but, of course, that option doesn't exist. Death can't be accepted because it can't be rejected; that option doesn't exist. The only thing you can do is realize that you exist now, and that's great. Enjoy Existence while we live, and then... Nothing.
