Dim spiral galaxy IC 5332 from HST and JWST

IC 5332, also known as PGC 71775 is an intermediate spiral galaxy about 30 million light-years away in the constellation Sculptor. IC 5332 is a delicate spiral galaxy that is unusually faint and beautifully symmetrical. As viewed from earth it is nearly face on. It has a very small central bulge and open spiral arms accounting for its classification (SABc). The galaxy lies in the direction of the celestial south pole. I wanted to highlight the JWST dust lanes more clearly, so I decided to stick to […]

Perfect spiral M74 from JWST and Hubble

Processing galactic images with both JWST and HST data is just incredible. Normally, every spiral galaxy (and some elliptical ones too) have dark dust lanes obscuring the light from the stars behind. These dark spirals add depth to the image, but unfortunately don’t contain much information. But with the added infrared imagery, the glowing strands and flocks of dust, which would normally be dark in visible light imagery, are instead bright and glowing with infrared light from JWST. Below is a comparison of the Hubble visible-light image […]

Hubble’s stunning 3-color mosaic of the Tarantula nebula

Below is a zoomable version of the tarantula nebula. You can also view this version here: http://www.gigapan.com/gigapans/230324. If you have a minute or ten, I really hope you spend some time just looking at the various little complications in this image – I assure you that it will be well worth your time! The full jpg version is available for free use on my flickr, which you can access by clicking the link below: If you would like to use a higher-quality version, feel free to email […]

Interesting Astronomy news from the week of 8/14/2022

Read about the coolest discoveries, research updates, and images of this week’s astronomy: New insights into turbulence raging inside distant stars, a discovery of one of the largest black hole jets, and a beautiful image of a comsic dance! New insights into turbulence raging inside distant stars Stunning new images created by Keele researchers highlight the turbulent flow of energy inside distant stars. They were created using the 3D simulation software “PROMPI”, which scientists have been using to investigate stellar interiors with the aim of understanding the […]

NGC 4490 from Hubble

Compared to the other fundamental forces in the Universe, gravity is fairly weak. Despite this, gravity has an influence over huge distances and is the driving force behind the motions of the most massive objects in the cosmos. The scattered and warped appearance of the galaxy in this image, NGC 4490, is a prime example of the results of gravity’s unrelenting tug.

The interacting triplet M81, M82, and NGC 3077- An ultra deep 219 hour collaboration detailing the nuanced interaction remnants and galactic cirrus.

This incredibly detailed image of the interacting triplet M81, M82, and NGC 3077 was created from more than 216 hours of exposure across three continents —  Europe, USA, and Oceania. We combined 4019 subframes and 12993 minutes of exposure to reveal faint details previously masked by lower amounts of data. The high exposure time also allowed us to sharpen fine features, giving the image more contrast and revealing more fine structures. On the top of the image lies NGC 3077, a small starburst dwarf galaxy with a […]

Barred Spiral Galaxy NGC 1300 from Hubble

The Hubble telescope captured a display of starlight, glowing gas, and silhouetted dark clouds of interstellar dust in this 4-foot-by-8-foot image of the barred spiral galaxy NGC 1300. NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. At Hubble’s resolution, a myriad of […]

Hubble’s view of the dusty spiral galaxy M66

The big and beautiful spiral galaxy messier 66 is perhaps one of the most dusty and exciting galaxies to explore. With the recent PHANGS-HST proposal, this galaxy was observed in the ultraviolet, visable, and near-infrared wavelegnths in a way that makes this island universe much easier to understand. First, shining brightly in the infrared are the young star clusters, shown in the image below as blue. Then, in the visible light spectrum, the dust lanes cascading over the stars come into sharp relief. Finally, in the infrared, […]

A spectacular head-on collision between two galaxies – ARP 143 from Hubble

A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope. The interacting galaxy duo is collectively called Arp 143. The pair contains the glittery, distorted, star-forming spiral galaxy NGC 2445 at right, along with its less flashy companion, NGC 2444 at left. Astronomers suggest that the galaxies passed through each other, igniting the uniquely shaped star-formation firestorm in NGC 2445, where thousands of stars are bursting to life on the right-hand side of […]
