🔭 M83: The Southern Pinwheel

Beautiful and bright spiral galaxy M83 lies a some twelve million light-years away, near the southeastern tip of the very long constellation Hydra. Prominent spiral arms traced by dark dust lanes and blue star clusters lend this galaxy its popular name, The Southern Pinwheel. Still, reddish star forming regions that dot this cosmic pinwheel's spiral arms have suggested another nickname, the Thousand-Ruby Galaxy. A mere 40,000 light-years across, smaller than the Milky Way, M83 is a member of a group of galaxies that includes active galaxy Centaurus A. In fact, the core of M83 itself is bright at x-ray energies, showing a high concentration of neutron stars and black holes left from an intense burst of star formation. This sharp color image also features spiky foreground Milky Way stars and distant background galaxies. The image data was captured with the Dark Energy Camera and Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory.

🔭 Supernova Remnant Cassiopeia A

Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light 11,000 years to reach us. This sharp NIRCam image from the James Webb Space Telescope shows the still hot filaments and knots in the supernova remnant. The whitish, smoke-like outer shell of the expanding blast wave is about 20 light-years across. A series of light echoes from the massive star's cataclysmic explosion are also identified in Webb's detailed images of the surrounding interstellar medium.

🔭 Supernova Remnants Big and Small

A star field appears that has several nebulas. Toward the upper left is a angularly small supernova remnant colored blue, while dominating the lower right is a large supernova remnant in both red and blue. Please see the explanation for more detailed information.

🔭 Solar Analemma 2024

Image Credit & Copyright: Betul Turksoy

apod.nasa.gov/apod/ap25010...
Recorded during 2024, this year-spanning series of images reveals a pattern in the seasonal drift of the Sun's daily motion through planet Earth's sky. Known to some as an analemma, the figure-eight curve was captured in exposures taken only at 1pm local time on clear days from Kayseri, Turkiye. Of course the Sun's position on the 2024 solstice dates was at the top and bottom of the curve. They correspond to the astronomical beginning of summer and winter in the north. The points along the curve half-way between the solstices, but not the figure-eight curve crossing point, mark the 2024 equinoxes and the start of spring and fall. Regional peaks and dormant volcano Mount Erciyes lie along the southern horizon in the 2024 timelapse skyscape.

Some less awkward-to-the-point-of-hostility snaps from the last week 😂 I'll probably go through the ones from over the new year today

Make sure you activate the skill first! 😆

TIL Alexa has a Monster Scanner skill that reassures your kids that there's nothing lurking under their bed.

We decided to try it for curiosity's sake, but forgot to activate that specific skill.

"Alexa, look up child psychotherapists in my neighborhood."
A transcript of an Alexa response to "Alexa, are there any monsters under my bed?" The response says "Yes. Bedbugs are reddish brown and roughly the size of an apple seed. They infest homes, hotels, and hospitals. They often enter your home undetected and hide in beds, biting humans to feed on their blood."

You may not be aware of this fact, but we all need more cat pics in our feeds.

I hope this weekend brings you as much serenity as my chonky, blissed out cat.

I suspect belly rubs are the key.

This open star cluster is called NGC 225, or the Sailboat Cluster. There's also some interesting nebulosity in the region. I think I need at least another full night of this before it really comes together. #Astronomy #Astrophotography
