Spiral Galaxy NGC 3147 from Hubble

The graceful, winding arms of the majestic spiral galaxy NGC 3147 appear like a grand spiral staircase sweeping through space in this Hubble Space Telescope image. They are actually long lanes of young blue stars, pinkish nebulas, and dust in silhouette. The beauty of the galaxy belies the fact that at its very center is a malnourished black hole surrounded by a thin, compact disk of stars, gas, and dust that have been caught up in a gravitational maelstrom. The black hole’s gravity is so intense that […]

ARP 274 from Hubble

To celebrate my 18th birthday, I decided to process one of my favorite Hubble images! This was taken back in 2009 to celebrate the International Year of Astronomy by WFPC2. Given that it was taken by such a low-sensitivity sensor, this image actually had a whole lot of noise to deal with. I spent a while carefully removing hot pixels and cosmic rays to make the image look better. In case you’re wondering what exactly you’re looking at, here’s a little explanation about the galaxies: Arp 274 […]

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 infrared view of the Horsehead Nebula

Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery over a century ago. The nebula is a favorite target for amateur and professional astronomers. In this new Hubble Space Telescope view, the nebula appears in a new light, as seen in infrared wavelengths. The nebula, shadowy in optical light, appears transparent and ethereal when seen in the infrared, represented here with visible shades. The rich tapestry of the Horsehead Nebula pops out against the […]

Hypersonic superheated rainbow outflows from a dying star – NGC 6302 from Hubble

This image was featured as NASA’s astronomy picture of the day on 11/21/2022: https://apod.nasa.gov/apod/ap221121.html The spectacular planetary nebula NGC 6302 lies roughly 3,800 light-years away in the constellation Scorpius. More popularly known as the Bug Nebula or the Butterfly Nebula, this celestial object looks like a delicate butterfly. But what resemble dainty wings are actually roiling regions of gas heated to more than 36,000 degrees Fahrenheit. The gas is tearing across space at more than 600,000 miles an hour — fast enough to travel from Earth to […]

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 […]

NGC 2276 from Hubble

The magnificent spiral galaxy NGC 2276 looks a bit lopsided in this Hubble Space Telescope snapshot. A bright hub of older yellowish stars normally lies directly in the center of most spiral galaxies. But the bulge in NGC 2276 looks offset to the upper left. In reality, a neighboring galaxy to the right of NGC 2276 (NGC 2300, not seen here) is gravitationally tugging on its disk of blue stars, pulling the stars on one side of the galaxy outward to distort the galaxy’s normal fried-egg appearance.
