NGC 4676 from Hubble

Update 10/4/2021: This image has been chosen as an APOD by NASA! You can view their write-up here: https://apod.nasa.gov/apod/ap211004.html. These two mighty galaxies are pulling each other apart. Known as “The Mice” because they have such long tails, each spiral galaxy has likely already passed through the other. They will probably collide again and again until they coalesce. The long tails are created by the relative difference between gravitational pulls on the near and far parts of each galaxy. Because the distances are so large, the cosmic […]

The Antennae Galaxies from Hubble

The galaxies in this image — also known as NGC 4038 and NGC 4039 — are locked in a deadly embrace. Once normal, sedate spiral galaxies like the Milky Way, the pair have spent the past few hundred million years sparring with one another. This clash is so violent that stars have been ripped from their host galaxies to form a streaming arc between the two. In wide-field images of the pair the reason for their name becomes clear — far-flung stars and streamers of gas stretch out into […]

M83 from Hubble

This is definitely the largest and most beautiful image I have processed to date. Hubble took a stunning 6 panel mosiac in 5 different color bands to create this awesome astrograph. I highly recommend checking out the full mosiac hosted on gigapan: http://www.gigapan.com/gigapans/227085. The Hubble photograph captures thousands of star clusters, hundreds of thousands of individual stars, and “ghosts” of dead stars called supernova remnants. The galactic panorama unveils a tapestry of the drama of stellar birth and death spread across 50,000 light-years. The newest generations of […]

NGC 3603 from Hubble

Like a 4th of July fireworks display, a young, glittering collection of stars looks like an aerial burst. The cluster is surrounded by clouds of interstellar gas and dust—the raw material for new star formation. The nebula, located 20,000 light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603. This environment is not as peaceful as it looks. Ultraviolet radiation and violent stellar winds have blown out an enormous cavity in the gas and dust enveloping the cluster, providing an […]

The dumbbell nebula from Hubble

When Hubble processes images, they usually crop to the most interesting part. This image, however, shows the entire area captured by the sensor! The pure black areas in this image are parts where there is no sensor. This image looks to me more like a painting than a photo. Tho colors, the bulbos shapes, the small details all look like oil on canvas. Image: Details: All data was taken by Hubble’s Wide Field Planetary Camera 2 (WFPC2) from the following proposal: https://archive.stsci.edu/proposal_search.php?mission=hst&id=8726 Processing Stretch each channel combine colors […]

NGC 7049 from Hubble

The NASA/ESA’s Hubble Space Telescope has captured this image of NGC 7049, a mysterious looking galaxy on the border between spiral and elliptical galaxies. NGC 7049 is found in the constellation of Indus, and is the brightest of a cluster of galaxies, a so-called Brightest Cluster Galaxy (BCG). Typical BCGs are some of the oldest and most massive galaxies. They provide excellent opportunities for astronomers to study the elusive globular clusters lurking within. The globular clusters in NGC 7049 are seen as the sprinkling of small faint […]

Hubble’s Pillars of creation – M16

This was a tough image to process – there were a bunch of tiny dark gaps and hot pixels scattered throughout the image. The image file sizes were also quite big, so processing took a long time. Nevertheless, I got a result that I am proud of! The data is just too good to process badly. I have to give so much credit to the HLSP team – they really did a phenomenal job creating this mosaic. These towering tendrils of cosmic dust and gas sit at […]

NGC 520 from Hubble

Update 9/7/2021: This image has been chosen as and APOD by NASA! You can view their write-up here: https://apod.nasa.gov/apod/ap210907.html. This galaxy is just so bizarre that I had to process it! NGC 520 is the product of a collision between two disc galaxies that started 300 million years ago. It exemplifies the middle stages of the merging process: the discs of the parent galaxies have merged together, but the nuclei have not yet coalesced. It features an odd-looking tail of stars and a prominent dust lane that […]

ARP 273 from Hubble

This is one of my absolute favorite galaxies, so I had to take a shot at processing it! The whirling spirals, the dark dust lanes, the beautiful colors – Hubble really picked a great target! From APOD’s description (4/21/2011): “The spiky stars in the foreground of this sharp cosmic portrait are well within our own Milky Way Galaxy. The two eye-catching galaxies lie far beyond the Milky Way, at a distance of over 300 million light-years. Their distorted appearance is due to gravitational tides as the pair […]

The Tadpole galaxy, taken by Hubble and processed by me

The Tadpole Galaxy is a disrupted barred spiral galaxy located 420 million light-years from Earth in the northern constellation Draco. Its most dramatic feature is a massive trail of stars about 280,000 light-years long; the size of the galaxy has been attributed to a merger with a smaller galaxy that is believed to have occurred about 100 million years ago. The galaxy is filled with bright blue star clusters. Image: Processing: I created this image with 3 filters taken by the Hubble ACS camera: near- infrared (814nm), […]
