Hubble Observes Barred Spiral Galaxy NGC 4424

In this Hubble image the barred spiral galaxy NGC 4424 is seen edge on, but from above you would be able to see the arms of the galaxy wrapping around its center to give the characteristic spiral form. The smaller, flatter, bright galaxy sitting just below NGC 4424 is named LEDA 213994. Image credit: NASA / ESA / Hubble.

The NASA/ESA Hubble Space Telescope has taken a picture of the galaxy NGC 4424, which is found in the constellation of Virgo. In this Hubble image the barred spiral galaxy NGC 4424 is seen edge on, but from above you would be able to see the arms of the galaxy wrapping around its center to give the characteristic spiral form.

Reconstruction of Umaltolepis mongoliensis showing four seed-bearing structures and attached Pseudotorellia resinosa leaves. Note that three seed-bearing organs have split at the level of the flange into four lobes releasing the seeds. The seeds (right) were probably membranous and wind-dispersed. The cupule has been shed from one of the seed-bearing structures leaving the stalk, flange and column attached to the short shoot. Most, probably all, of the small dark spots on leaves are the remains of fungal stromata. Image credit: Fabiany Herrera et al, doi: 10.1073/pnas.1621409114.

The elliptical galaxy 3C186, located about 8 billion years from Earth, is most likely the result of a merger of two galaxies. This is supported by arc-shaped tidal tails, usually produced by a gravitational tug between two colliding galaxies, identified by M. Chiaberge et al. The merger of the galaxies also led to a merger of the two supermassive black holes in their centers, and the resultant black hole was then kicked out of its parent galaxy by the gravitational waves created by the merger. The bright, star-like looking quasar can be seen in the center of the image. Its former host galaxy is the faint, extended object behind it. Image credit: NASA / ESA / M. Chiaberge, STScI.

Showcase of the different types of changes identified in high-resolution images of 67P/Churyumov–Gerasimenko during more than two years of monitoring by ESA’s Rosetta spacecraft. The approximate locations of each feature are marked on the central context images. Dates of when the ‘before’ and ‘after’ images were taken are also indicated. Note that the orientation and resolution between image pairs may vary, therefore in each image set arrows point to the location of the changes, for guidance.
