A 62-hour widefield image of Orion

Edit 2/11/2023: This image was featured by NASA’s universe view screen Instgram, Astronomy Magazine’s image of the day: https://astronomy.com/photos/picture-of-day/2023/02/a-wide-view-of-orion, and the Amateur Astronomy Image of the Day: https://www.aapod2.com/blog/M42 The dark Horsehead Nebula and the glowing Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of the night sky’s most recognizable constellations, they appear in opposite corners of the image. The familiar Horsehead nebula appears as a dark cloud, a small silhouette notched against the long red glow at the lower left. Alnitak is the […]

Orion Widefield

Cradled in cosmic dust and glowing hydrogen, stellar nurseries in Orion the Hunter lie at the edge of a giant molecular cloud some 1,500 light-years away. Spanning nearly 25 degrees, this breath-taking vista stretches across the well-known constellation from head to toe (left to right). The Great Orion Nebula, the closest large star forming region, is right of center. To its left are the Horsehead Nebula, M78, and Orion’s belt stars.

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 […]

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 […]

Hershel’s image of the upper orion molecular complex

Stunning new view from ESAs Herschel space observatory of the iconic Horsehead Nebula in the context of its surroundings. The image is a composite of the wavelengths of 70 microns (blue), 160 microns (green) and 250 microns (red), and covers 4.5×1.5 degrees. The image is oriented with northeast towards the left of the image and southwest towards the right. The Horsehead Nebula resides in the constellation Orion, about 1300 light-years away, and is part of the vast Orion Molecular Cloud complex. The Horsehead appears to rise above […]

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.

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 […]

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 […]
