Hot new #JWST image just dropped. (Literally hot; the temperature inside this object can reach upward of 25,000 degrees.)

Meet the planetary #nebula NGC 1514, aka the "Crystal Ball Nebula". It's about 1500 light years away from Earth in the direction of the constellation Taurus.

Planetary nebulae occur toward the end of the lives of #stars that have about the mass of the Sun. They shed their outer layers into space, leaving behind an Earth-sized star called a white dwarf. Its temperature can be up to about 100,000 degrees, so it emits a lot of ultraviolet and X-ray light. That light energizes the gas ejected during the earlier phase, lighting it up like a neon sign. (NGC 1514's white dwarf is the bright star at the center with the spikes, which are an artifact of the telescope's optics.)

This image is a composite of individual frames made through three colored filters by the Webb telescope's Mid-Infrared Instrument (MIRI). The image shows two concentric shells of material whose bright edges appear as circles. It's actually an hourglass-shaped structure seen an angle inclined to our line of sight toward NGC 1514.

A newly published study finds that these rings are different than the reddish material inside them. The light they emit comes from very tiny grains of carbon-rich material given off by the progenitor star very late in its life.

But why the ring shapes? It turns out that the progenitor star was actually two, only one of which endured this phase of high mass loss. Energetic "winds" given off by the stellar pair shaped the carbon grains as they were pushed away from the system.

A colorful planetary nebula appears on a dark background. The nebula is a range of colors from red to pink to orange to white and consists of an inner reddish region surrounded by two diffuse gray/white rings tilted at 45 degrees toward the lower right. A bright star appears in the center with six short diffraction spikes. Faint stars and galaxies are scattered across the background.

APOD from 2025-02-11

The Spider and the Fly

In the constellation Auriga, emission nebulas IC 417 (Spider) and NGC 1931 (Fly), both about 10,000 light-years away, house young star clusters. The deep image from Berkshire UK reveals these cosmic clouds with the Fly spanning 10 light-years.

I found the “sister” of M33. Her name, NGC2403. They are pretty much alike. Have more or less the same size, shape, and they both feature a very big nebula: NGC604 in M33 and NGC2404 in the sister galaxy. Though, they got mad of each other, and now they are millions of l-y appart.

A spiral galaxy, spotted with pink blobs here and there, has a bright and tight core in its center. The arms of the galaxy expand and fade away into the vacuum of space. Although of majestic aspect, it’s only half the size of our own galaxy.

There are mighty rivals for the famous Pillars of Creation in the Eagle Nebula, like these, located in the not so famous SH2 284 nebula. You can find these in the Unicorn.

An explosion of colorful clouds, layered in reddish, yellow, green and blue shades, stained with dark clouds that give the object character and depth. Many distant stars sparkle the whole picture.

Two anonymous anemonae! LBN 807 is a strong emission nebula that is being carved by numerous and potent young blue stars.

Shot for a total of about 14 hours from my observatory on a rooftop in Mexico City.

Some say the distinguishing features of this nebula look like tadpoles… I don’t think so 🙂.


First post over here after leaving the bin fire that was twitter. Now need to try and find all the Astrophotographers over here to connect with, all recommendations greatfully received. #Astrophotography #Space #Nebula #Astronomy
