Liller 1 is a particularly interesting globular cluster, because unlike most of its kind, it contains a mix of very young and very old stars. The oldest stars are 12 billion years old, twice as much older than our Sun. The younger ones are about 1-2 billion years old.

Liller 1 is located at the Milky Way's bulge region, which visible light that our eyes can see is blocked. So we cannot see this cluster.

However, thanks to the Hubble Space Telescope's WFC3 instrument, which can see infrared light that is invisible to us, it can peer through and see Liller 1.

The blue regions in visible light represent areas of neutral hydrogen gas, here being seen in a much larger scale, not visible from previous images. The red areas glowing in radio and infrared light represent dust and gas heated by young, hot stars, more prominent on the Cigar Galaxy.

Meanwhile, this is the supernova remnant detected by Webb in infrared. These show gases and debris that glow and are "baked" by the hotter, X-ray emitting clouds visible in Chandra. Green is hotter than the red ones. The C-shaped structure at the right of center is the "Green Monster."

Here is another labelled map with Chandra with the help of NASA's NuSTAR instrument, showing more elemental debris. These glow due to the decay of radioactive elements. Pristine debris, or those not affected by the supernova explosion shock waves, are also highlighted.

Here is the supernova remnant as observed by the Chandra telescope, outlining regions of element-rich debris and supersonic shock waves. The "Green Monster" structure is also visible, formed when the supernova explosion interacted with the material expelled by the star thousands of years ago.

Located about 4,100 light-years away from Earth, it consists of a cluster of thousands of young stars blowing away gases and dust in strong stellar winds. The most massive of them is HD 164492A, an O7.5III giant star 20 times more massive than the Sun.

Exposure time was 714 minutes Luminance, 120 minutes Red, 72 minutes Green and 162 minutes Blue.

This image was made using a series of exposures taken between August 2-4, 2008 and May 25-31, 2006 through a RCOS 20- inch telescope and a SBIG STL-11000 camera in the Blackbird Observatory near Mayhill, New Mexico.

Also of note is the extensive spiral arms visible in this image, which are tidally disrupted by past mergers. The galaxy is quite large, about 170,000 light-years across.

Unlike the traditional Hubble image, here we can see more of its flowing, extensive spiral arms with bright red patches, which are its star-forming H II regions with hot, blue stars.
