Mind-Blowing Scale: Betelgeuse Compared to Our Solar System! 🤯☀️

Imagine replacing our Sun with the colossal red supergiant star, Betelgeuse! Its size is absolutely staggering—it would extend beyond the orbit of Jupiter, swallowing Mercury, Venus, Earth, Mars, and a chunk of the asteroid belt! 😱

And the cosmic drama doesn't end there!

🚨 New header picture 🖼️

It shows the two supernova remnants Cassiopeia A (left, in X-rays) and Vela Jr. (right, at radio wavelengths). Both harbor a “central compact object”, a neutron star left behind together with the debris cloud after the supernova.

Researchers from the permanent independent @maxplanckgesellschaft research group “Continuous Gravitational Waves” at @mpi_grav in Hanover, Germany, have been searching for gravitational waves from these central compact objects using the volunteer distributed computing project @einsteinathome.

📄 arxiv.org/abs/2503.09731

The fact that they did not find any gravitational waves indicates that the neutron stars can only be minimally deformed.

🔭 What Will the Betelgeuse Supernova Be Like - And Will It Hurt Us?
—@universetoday

｢ It will be visible during the day. It will be brighter than any planet. It will be almost as bright as the full moon. You'll be able to read a book by the light of the Betelgeuse supernova at midnight ｣

Hobby update! 🔭🛸👾

Last week some clear nights; and with my second set I didn’t knew what to target and shoot. So kinda was hopping around and found this very very very faint target. Didn’t knew what it was; had to look it up.

Ultimately I had to do 600 second and 1200 second 🫣 subs. Yeah. That’s 20 minutes for one shot. And that a challenge I didn’t tackle before.

But. Here she is: CTB-1 Supernova remnant in HOO (Garlic Nebula)

Dark Energy Survey ondersteunt theorie van evoluerende donkere energie

Het Lambda-CDM-model (ΛCDM) vormt al enige tijd de basis van de moderne kosmologie en beschrijft met succes grootschalige structuren in het heelal. Het stelt voor dat 95% van het heelal bestaat uit donkere m

Happy Saint Patricks Day! This image and link is to a distant galaxy and green Supernova. previously unreported until I found it last July in Telescopium constellation using public data via Legacy Survey of the night sky and ingoing mapping. you can select any object on the zoomable map and look it up in Simbad, single exposures or discuss object on the LS Forum. #SaintPatricksDay #Stars #Green #space #astronomy #legacysurvey #supernova #leprechaun #fourleafclover #galaxy
