Clumps of molecular gas overlaid on Sagittarius A* circumnuclear disk as seen by ALMA in the CS(7-6) line. Yellow circles are thin clumps that are going to be shredded by the gravitational force of supermassive black hole Sagittarius A*. Green circles are dense enough to survive the tidal shredding but are not able to form stars. Purple/pink circles have the needed density to form stars, but no star formation has been observed.

This Hubble image shows the free-floating evaporating gaseous globule J025157.5+600606. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

A 5-light-year-long section of the western wall in the Carina Nebula, as observed with adaptive optics on the Gemini South telescope. This mountainous section of the nebula reveals a number of unusual structures including a long series of parallel ridges that could be produced by a magnetic field, a remarkable almost perfectly smooth wave, and fragments that appear to be in the process of being sheared off the cloud by a strong wind. There is also evidence for a jet of material ejected from a newly-formed star. The exquisite detail seen in the image is in part due to a technology known as adaptive optics, which resulted in a ten-fold improvement in the resolution of the research team’s observations.

This artist’s impression shows ‘Oumuamua, the first interstellar object discovered in our Solar System. Recent observations show that the object is moving faster than predicted while leaving the Solar System. Astronomers assume that venting material from its surface due to solar heating is responsible for this behavior. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. Image credit: NASA / ESA / Hubble / ESO / M. Kornmesser.
