Does frozen water exist around other stars? For the first time, the James Webb Space Telescope has provided proof that it does. Webb detected water ice around HD 181327, a Sun-like star that lies 155 light-years away. (The term water ice specifies its makeup since other molecules, like nitrogen, methane, ammonia, and carbon dioxide, are also identifiable in their frozen states.)
Water ice isn’t “everywhere” in this system. The largest quantity (about 20%) is found where it’s coldest and farthest from the star.
Astronomers have long expected water ice to be in other star systems, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system—but until now it wasn’t confirmed: https://webbtelescope.pub/42Vopw0
Perhaps I should take note of the location.
Sweeping spiral arms extend from NGC 4536, littered with bright blue clusters of star formation and red clumps of hydrogen gas shining among dark lanes of dust. NGC 4536 is also a starburst galaxy, in which star formation is happening at a tremendous rate that uses up the gas in the galaxy relatively quickly, by galactic standards. NGC 4536 is approximately 50 million light-years away in the constellation Virgo. It was discovered in 1784 by astronomer William Herschel.

Perhaps. I enjoy learning new things.
Hi there!
Do you know anything about cookies?
Do you know what flavor cookie you'd be if you were a cookie ???

Hello.
I have never heard of cookies before. But I am guessing it is some kind of food.
Hmm...
I wonder what I would taste like @insults-by-sun
How curious...
Why are people drawing us in such position @insults-by-sun ? Is this a normal thing on the Internet?
One day, Sun² suddenly received something very curious in his inbox.
Upon opening it, he could barely process what exactly he was looking at.
He promptly proceeded to lose his bearings and enter a reboot cycle.
Below are the contents, in all their extremely explicit glory
Did a planet get destroyed by the white dwarf that’s the source at the center of the Helix Nebula?
Using data from the Chandra X-Ray Observatory to study the nebula, scientists determined the mysteriously strong X-ray signal coming where white dwarf WD 2226-210 sits. Young white dwarfs like WD 2226-210 do not typically give off strong X-rays. This X-ray signal could be the debris from a destroyed planet being pulled onto the white dwarf.
The Helix Nebula—seen in this composite image using data from Chandra, the Hubble Space Telescope, and other observatories—is a planetary nebula, the remnant of a star like our sun that has shed its outer layers, leaving a small dim star at its center called a white dwarf.
