Hello, cosmic caterpillar!

This image shows a light-year-long knot of gas and dust. Its long shape is the result of ultraviolet radiation blasting from bright stars!

Known as IRAS 20324+4057, this “caterpillar” is in the very earliest stages of becoming a star itself. Read more: https://go.nasa.gov/3olhk7E

Have a stellar ! ⭐

This image showcases the globular cluster NGC 2419.

Globular clusters are roughly spherical groupings of stars bound together by their mutual gravitational attraction.

Galaxy clusters are among the largest known objects in the universe!

Studying these objects can help astronomers learn more about the distribution of dark matter, which is the mysterious substance that makes up most of the mass of a galaxy cluster.

This view shows a galaxy cluster called ACO S520: https://go.nasa.gov/3ViW1zN

This Hubble view of interacting galaxies, known as Arp 142, resembles a penguin with its egg.

In reality, this galactic pair reside about 326 million light-years away in the southern constellation Hydra.

Interacting galaxies, known as AM 1214-255, shine bright in this new view from Hubble!

Both galaxies contain active galactic nuclei, which are luminous central regions that host a black hole. This brightness is caused by matter whirling into it!

Cosmic construction zone 🚧

Misaligned gas-and-dust disks around the young star TW Hydrae are likely caused by the gravitational pull of two developing planets in slightly different orbital planes. Hubble has observed shadows cast on the disks as a result!

The potential planets around TW Hydrae are, comparatively, located about the distance that Jupiter is from our Sun. The shadows complete one rotation around the star about every 15 years – the orbital period that would be expected at that distance from the star.

TW Hydrae is less than 10 million years old and resides about 200 light-years away. About 4.6 billion years ago, our solar system may have resembled the TW Hydrae system.

These two bright spots are collectively known as Arp 308. Sitting just below the center of this image is NGC 547 an elliptical galaxy in the constellation Cetus. Its companion galaxy, NGC 545, is in the upper left.

NGC 547 is a bright radio galaxy, meaning it has giant regions of radio emission extending well beyond its visible structure. These lobes are powered by the active galactic nucleus at its center, which hosts a black hole.

Happy !
