The galaxy featured in this Picture of the Week has a shape unlike many of the galaxies familiar to Hubble. Its thousands of bright stars evoke a spiral galaxy, but it lacks the characteristic ‘winding’ structure. The shining red blossoms stand out as well, twisted by clouds of dust — these are the locations of intense star formation. Yet it also radiates a diffuse glow, much like an elliptical galaxy and its core of older, redder stars. This galactic marvel is known to astronomers as NGC 1156.

This scintillating image showcases the globular cluster NGC 6540 in the constellation Sagittarius, which was captured by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys. These two instruments have slightly different fields of view — which determines how large an area of sky each instrument captures. This composite image shows the star-studded area of sky that was captured in both instruments’ field of view.

The galaxy NGC 7727 was born from the merger of two galaxies that started around a billion years ago. The cosmic dance of the two galaxies has resulted in the spectacular wispy shape of NGC 7727. At the heart of the galaxy, two supermassive black holes are spiralling closer to each other, expected to merge within 250 million years, the blink of an eye in astronomical time. This image of NGC 7727 was captured by the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument at ESO’s Very Large Telescope (VLT).

This celestial cloudscape from the NASA/ESA Hubble Space Telescope captures the colorful region in the Orion Nebula surrounding the Herbig-Haro object HH 505. Herbig-Haro objects are luminous regions surrounding newborn stars that form when stellar winds or jets of gas spew from these infant stars creating shockwaves that collide with nearby gas and dust at high speeds. In the case of HH 505, these outflows originate from the star IX Ori, which lies on the outskirts of the Orion Nebula around 1,000 light-years from Earth. The outflows themselves are visible as gracefully curving structures at the top and bottom of this image. Their interaction with the large-scale flow of gas and dust from the core of the nebula distorts them into sinuous curves.
