Image: Hubble spots stretching spiral

This sparkling spiral galaxy looks almost stretched across the sky in this new image from the NASA/ESA Hubble Space Telescope. Known as NGC 4100, the galaxy boasts a neat spiral structure and swirling arms speckled with the bright blue hue of newly formed stars.

Milky Way could be catapulting stars into its outer halo

Scientists used computer simulations to learn that our Milky Way galaxy may sometimes launch newly forming stars into the space around itself – that is, into the halo of our galaxy – via outflows triggered by supernova explosions.

Rotating galaxies galore: New results from ALPINE reveal what appear to be spiral galaxies in the infant universe

New results from an ambitious sky survey program, called ALPINE, reveal that rotating disk-shaped galaxies may have existed in large numbers earlier in the universe than previously thought. Source: https://phys.org/news/2020-04-rotating-galaxies-galore-results-alpine.html…

Astronomers investigate young stellar complexes in the galaxy UGC 11973

Astronomers have performed photometric and spectroscopic observations of young stellar complexes in the giant spiral galaxy UGC 11973. Results of this observational campaign provide important insights into the properties of these complexes. The study was detailed in a paper published April 9 on the arXiv pre-print repository.

Image: Hubble spots spirals within a spiral

At first glance, the subject of this NASA/ESA Hubble Space Telescope image looks to be a simple spiral galaxy, with two pinwheeling arms emerging from a central bar of stars and material that cuts through the galactic center. In fact, there are rings within these spiral arms, too: spirals within a spiral.  Source: https://phys.org/news/2020-04-image-hubble-spirals-spiral.html…

Image: Hubble captures a cannibal galaxy

This remarkable spiral galaxy, known as NGC 4651, may look serene and peaceful as it swirls in the vast, silent emptiness of space, but don’t be fooled—it keeps a violent secret. It is believed that this galaxy consumed another smaller galaxy to become the large and beautiful spiral that we observe today.
