A Natural Laboratory Of Spiralling Dust Shells
A Natural Laboratory Of Spiralling Dust Shells
The JWST has done it again. It's revealed new details hidden from lesser telescopes. The space telescope has detected four spiral dust shells around Apep, a triple star system about 15,000 light-years away.

The first photos from the Vera Rubin Observatory are stunning — thanks in part to the University of Arizona, which helped build its mirror. Proud to see Arizona leading the way in space science.

Zoom in on the Andromeda Galaxy with Hubble. What looks like a smudge of light to the unaided eye is actually a vast galaxy containing an estimated 1 trillion stars.

This is a terrific graphic for visualizing the differences between the various types of geothermal energy technologies.

A spiral galaxy, observed with the Apache Point 2.5m Telescope in the SDSS survey.
It is at redshift 0.039 (lookback time 549.7 million years) with coordinates (195.79164, 7.54859).
39 volunteers classified this galaxy in Galaxy Zoo 2.

Whoa: The European Space Agency's Solar Orbiter spacecraft got a spectacular view of Comet ATLAS (C/2024 G3) as it passed close to the Sun. Look at that enormous, splintered tail!
This comet won't be seen again for another 600,000 years. 🧪🔭
