NASA first released Hubble image of Veil Nebula in 2015. And now, six years later, the scientists have revisited it and re-edited it to make it look even more impressive. With a new set of filters applied, the photo now shows a more realistic and more detailed view of the Veil Nebula than before, and […]
As part of its celebration of a new year, the NASA/ESA Hubble Space Telescope has published six different galaxy mergers. These rare astronomical phenomena were captured as part of a recent survey to investigate the rate of new star formations.
As part of the release, NASA/ESA explains that these rare merging events show galaxies undergoing dramatic changes in their appearances and stellar content.
“These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions,” the organization writes. “The Milky Way typically forms star clusters with masses that are 10 thousand times the mass of our Sun. This doesn’t compare to the masses of the star clusters forming in colliding galaxies, which can reach millions of times the mass of our Sun.”
These events give off a lot of light, and even after the collision, when the resulting galactic system fades into a more calm state, the massive star clusters will continue to shine brightly.
These images are a selection of six out of a group of 59 that have been published as early as 2008 and as recently as October of 2020.
“By studying the six galaxy mergers shown here, the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey has investigated how star clusters are affected during collisions by the rapid changes that drastically increase the rate at which new stars are formed in these galaxies,” NASA/ESA writes.
“Hubble’s capabilities have made it possible to resolve large star-forming ‘knots’ into numerous compact young star clusters. Hubble’s ultraviolet and near-infrared observations of these systems have been used to derive star cluster ages, masses, and extinctions and to analyze the star formation rate within these six merging galaxies. The HiPEEC study reveals that the star cluster populations undergo large and rapid variations in their properties, with the most massive clusters formed towards the end of the merger phase.”
Hubble has taken quite a lot of stunning images over its three-decade-long existence. And recently, it took managed to capture a photo of the asteroid 16 Psyche in the most detailed image so far. What’s special about it? Well, one of the things that make it special is that it contains iron and nickel worth […]
Despite five repair missions it has gone through, the Hubble telescope has made it to the age of 30. NASA already share the stunning photo it took on its birthday back in April, but the celebration isn’t over yet. To mark Hubble’s 30th anniversary, NASA has added 30 more breathtaking photos to the already impressive […]
Every Sunday, we bring together a collection of easy reading articles from analytical to how-to to photo-features in no particular order that did not make our regular daily coverage. Enjoy!
Interview: Joe Biden’s Official Photographer Adam Schultz – “Every Day I Get to do This is a Special Day”– DPReview Adam Schultz is the official photographer for Joe Biden’s presidential campaign. In 2016 he worked on the Hillary campaign with Barbara Kinney, one of the White House photographers in the 90s, and before that worked at the Clinton Foundation for eight or nine years.
When he goes into a space, he’ll move around and get the typical shots, then get shots showing what the event looks like “from VP Biden’s perspective.” And that’s where a lens like the 100-400mm is great for getting those really tight shots. “One thing that I’m doing in this role is documenting what the candidate sees.”
In a smaller room, the trick is to take pictures of people standing on opposite sides of that room, with a 16-35mm. “But I’ll also back up on the 85mm, and for larger events, the really versatile 100-400mm is great. Being able to move around, both physically and in terms of the focal length is really important.” Schultz can’t wait to get out of this pandemic so that he does not have to hear mask wearers say ‘I’m smiling with my eyes’ when he records that once in a lifetime image.
If You Drop, Your 9th Will Pop! – DPReview The last time I heard that was when my orthopedist was bent over an x-ray of my vertebra after a slip and fall! Now the Lens Doctor is warning us that the same can happen to our lens elements? Has this anesthesiologist accidentally inhaled some of his own laughing gas? I guess not, as the proof is in the picture above. Most photographers have dropped a few lenses in their careers. The article delves into all the geeky stuff but then hits the nail on the head. If you drop your Nikon 70-200 f/2.8 VR II (and I have had many great versions all the way from Nikon 80-200mm f/4.5 N AI) “just right, the 9th element can actually pop out [ouch]of its molded plastic holder a tiny bit without causing any obvious external damage. It doesn’t happen very often, but when it does, it always pops out about 0.5mm, which, in optical terms, is a huge amount. This is the ‘one bad element’ scenario outlined in our mathematical experiment (photo above) earlier.” Q.E.D.
Even $2,000 lenses must have variation [in manufacture]. If you expect every copy of a lens to be perfect, then a dose of reality is in order – unreasonable expectations are a down payment on disappointment. – Dr. Roger Cicala
Rankin on the Dynamic Art of Beauty Photography– Wallpaper With nearly every famous face of the past 30 years in his portfolio, storied British photographer Rankin is a connoisseur of what people want to see. In his latest collaboration with German Braun shavers, he turns the camera on himself. His latest project featuring original portraits Say it with a Shave, celebrates the expressive nature of personal shaving. Rankin’s father shaved with a Braun in his car while driving to work, and he has been familiar with the brand for a long time.

This Space Photo Took Over 11 Days to Expose– Fstoppers Long exposures for most photographers are from a few seconds to get a dreamy waterfall, to a few minutes for a nightscape, to a few hours for astrophotography. This photo of nearly 10,000 galaxies is called the Hubble Ultra Deep Field and required 800 exposures taken over the course of 400 Hubble orbits around Earth. The total amount of exposure time was 11.3 days.
The snapshot includes galaxies of various ages, sizes, shapes, and colors. The smallest, reddest galaxies, about 100, may be among the most distant known, existing when the universe was just 800 million years old. The nearest galaxies – the larger, brighter, well-defined spirals and ellipticals – thrived about 1 billion years ago, when the cosmos was 13 billion years old. “Unlike any space telescope before it, Hubble made astronomy relevant, engaging and accessible for people of all ages,” writes NASA.

Quiz: (1.) How narrow is the angle of view of the Hubble Space Telescope compared to a Canon EF 1200mm f/5.6 L USM (The original price was MSRP $89,579 in the USA. And “no discounts” according to Mr. Chuck Westfall)?
Too tiny, tiny, tiny to describe! But since you are not going to let me alone unless I answer your question, here goes. If Hubble looked at the Earth — from its orbit of approximately 350 miles above the Earth’s surface — this would, in theory, correspond to a view of 12 inches or a human face. But Hubble would have to look down through the atmosphere, which would blur the images and make the actual resolution worse. Also, since Hubble orbits the Earth at 17,000 mph, any image it took would be blurred by the motion. Hubble’s so-called angular resolution — or sharpness — is measured as the smallest angle on the sky that it can resolve (i.e., see sharply). This is 1/10 of an arcsecond (one degree is 3,600 arcseconds). If you know of a better way to answer this, let us know in the comments below, as my head is already spinning (pun intended)!
(2.) How do you clean and protect the lens of the Hubble Space Telescope?
Hubble doesn’t have a lens. Like all large telescopes, Hubble uses a curved mirror (approx. 8 feet) to focus starlight. This mirror is located deep inside the telescope, protected by its long tube-like structure (think of it as a very long lens hood on a super-telephoto). As there is no atmosphere around Hubble, there is no risk of dust or corrosion reaching inside.
(3.) Why is Hubble able to see so much better than telescopes on Earth?
Because it is above the Earth’s atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So, Hubble’s images are much sharper than those from other telescopes. Also, Hubble is able to see in ultraviolet wavelengths that are blocked by the Earth’s atmosphere.
Irish Photographer Made Dolphin Famous for 30 Years– The Irish Times Photographer Ronan Quinlan’s images and story about Fungie, the dolphin, have been credited with starting the tourist trail to see the Dingle (Western Ireland) dolphin. Over one million people are estimated to have traveled to Kerry to see Fungie in the past three decades since Quinlan photographed him in 1987. His favorite photograph among those that helped bring world attention to the Dingle dolphin is one that shows Fungie making contact (photo above) with his fellow diver. However, Fungie has been missing this autumn after three decades, and the locals hope he’ll be back.
Photographer Creates Calendars Which Raise $12K+ Annually for Seattle Cancer Care Alliance – Seattle Refined Bainbridge Island photographer, Pete Saloutos recently made his annual appearance at the Seattle Cancer Care Alliance (SCCA) to give the calendars he designs and produces to the staff that saved his wife’s life four years ago. Saloutos started raising cash with calendars more than 15 years ago when a friend’s ovarian cancer diagnosis landed her in a financial crisis.
After his wife’s cancer diagnosis and treatment at SCCA in 2017, Saloutos pledged all future calendar proceeds to her care team there. The 2021 calendar is available in Seattle at Glazer’s Camera, other local stores and directly from Saloutos. “This is my way of giving back to my community using my photographic talents,” Saloutos tells PetaPixel.

Why Chrissy Teigen’s Pregnancy Loss Photos Are Important — And Common– Yahoo Life Teigen, 34, announced in a series of emotional hospital room photos on Instagram that she and her husband John Legend, 41, lost their unborn son, three days after Teigen was hospitalized for bleeding issues. “I had asked my mom and John to take pictures, no matter how uncomfortable it was…These photos are only for the people who need them,” describes the model and TV personality in all the details in a Medium essay.
“There are some people who think it’s somewhat morbid,” says Dawn McCormick, a New York-based photographer who volunteers for Now I Lay Me Down to Sleep, an organization that offers free professional portraits to parents who are experiencing the loss of a baby. “I don’t think they realize that because they have pictures of their children throughout their life, these are the only pictures these people will ever have of that child.”
Photography in Politics and the 2020 Presidential Campaign –Rangefinder They say a picture is worth a thousand words. Political pictures? It depends on who you ask, which is why we thought it important, during the Elections, to look at some political photography. PHOTOPLUS, which was founded in 1983 and is the largest photography and imaging event in North America, had scheduled a talk by two photographers who have been covering the 2020 presidential campaign, as well as the political scene and past presidents, for some time now, Rick Friedman and Eric Thayer. However, they were forced to go virtual. You can watch a replay of both these talks by registering for free at PHOTOPLUS.
“Everything is much more staged these days than in the past,” Rick Friedman tells PetaPixel. “Press aides will tell you where you can stand and where you cannot. Events are much more choreographed, even in the early stages of the primary season. The days of going into someone’s house with the candidate are over, except in the very early stages of the primaries, and even then, you might need to be credentialed. The most enjoyable part is very early in the campaign when it is less restrictive, and you get to capture how the candidates interact with average citizens.”
Why I Like This Photo – Rick Sammon I made this photograph in Venice, Italy, during Carnevale 2018. It’s the result of what I call my “One-picture Promise.” My promise: When you are in a situation, ask yourself, If I could take only one picture, what would that one picture be? Think about the one lens, one aperture/shutter speed/ISO, one background, one composition, and so on. Your answers will result in a higher percentage of “keepers,” more creative images and fewer outtakes. I promise.
When photographing this woman, I considered all those options. I also followed three of my tips:
1) When you think you are close, get closer
2) The closer you are to the subject, the more intimate the photograph becomes
3) See eye-to-eye and shoot eye-to-eye.
To make this image, I used my Canon EOS 5D Mark IV with 24-105mm IS lens set at 35mm. EXIF info: f/9, 1/50th of a second, ISO 640.
You could say this picture is the result of using the photographer’s most valuable accessory: the human brain. It’s also the result of a time-proven photo adage: Never underestimate the importance of an interesting subject.

In just one relatively small “bulge” of the Soul Nebula (also known as Westerhout 5) in the constellation of Cassiopeia, the Hubble Space Telescope has captured an image of a star that is still being born.
The corner of the nebula cloud is about 7,500 light-years away and the small corner in question, called J025157.5+600606, depicts what is known as a FrEGGs – Free-Floating Evaporating Gaseous Globules. FrEGGs were only very recently discovered and require a specific set of conditions in order to occur.
According to a description on ScienceAlert, stars in these large clouds of stellar “nurseries” are formed from “cool clumps of dense molecular hydrogen that collapse under their own gravity.” As a result, these stars come into being “nestled in thick, molecular clouds.”
“When a very massive, hot star starts to shine, their intense ultraviolet radiation ionizes their birth cloud, creating a large, hot bubble of ionized gas called a Strömgren sphere,” ScienceAlert describes.
FrEGGs are the dense clumps of cooler gas that cluster around a Strömgren sphere and apparently many of these can continue to form stars of their own.
The boundary between the FrEGGs and the sphere is depicted in the image from the Hubble telescope as the glowing purple region. “Because the FrEGGs are so dense, this process doesn’t stop the star formation occurring inside. But it does, ultimately, hinder it, curtailing the gas supply that would feed the star forming within.” As a result, the stars born inside a FrEGGs are relatively low mass when compared to other stars.
These smaller lower mass, cooler temperature stars can actually last longer than the larger, hotter siblings. Some suggest this might be how our own star, often poetically referred to as Sol, was formed.
If you’re curious how photos like the ones here are constructed, it’s not as straightforward as you might think. The Hubble Space Telescope doesn’t capture full-color images, as described in a 2015 interview with CalTech scientist Robert Hurt.
“The main difference between normal astronomical data collection and earthbound photography is that astronomy is intrinsically monochromatic,” Hurt told Resource Magazine. “That image may be obtained through a filter, a detector, but we’re only getting back one channel of information at a time.”
The beautiful colors seen in the image of J025157.5+600606 were interpreted from the multi-channel infrared images sent back from Hubble by a trained scientist like Hurt.
Hubble captured the above image of anotehr FrEGGs earlier this year, also located in Cassiopeia. You can learn more about that image here.
Hubble Space Telescope has been in space for over 30 years and has treated us with plenty of awe-inspiring images. This time, the telescope has captured quite a firework. It took a photo and timelapse of a bright supernova outshining every star in its galaxy and unleashing the energy of 5 billion Suns. NASA writes that […]
NASA has just published a stunning, one-of-a-kind time-lapse captured by the Hubble telescope. The short video shows an exploding star (AKA a supernova) in a galaxy 70-million light-years from Earth—a fireworks show so bright it outshone every other star in its galaxy before fading into oblivion.
In total, the time-lapse captures a full year of observations from February 2018 to February 2019. During this time, the supernova in galaxy NGC 2525 reached peak brightness, outshining every other star in its own galaxy, before “fading into obscurity” as humans watched on from million of light years away.
As Nobel Laureate Adam Riess put it in a blog post on the Hubble website, “no Earthly fireworks display can compete with this supernova, captured in its fading glory by the Hubble Space Telescope.”
You can see a wide-angle view of the full galaxy below, with the supernova very obviously shining on the outer edge of one of its spiral arms:
According to NASA, the energy released was “equal to the radiance of 5 billion Suns,” a light show worth capturing to be sure. However, Hubble wasn’t just interested in this supernova because NASA is eager to share celestial fireworks with the public; this kind of supernova is important in measuring our distance to its host galaxy and answering questions about the expansion of the universe.
“Because supernovae of this type all peak at the same brightness, they are known as ‘standard candles,’ which act as cosmic tape measures,” explains NASA. “Knowing the actual brightness of the supernova and observing its brightness in the sky, astronomers can calculate the distances of their host galaxies. This allows astronomers to measure the expansion rate of the universe.”
To learn more about this process or see more images of this supernova, head over to the Hubble website or check out the time-lapse video up top. Whether or not you’re interested in the science behind the photograph though, you have to admit that NASA captured something truly incredible here.
It’s crazy to think that the Hubble Space Telescope has been floatin’ around in space for over 30 years now. But since launch day on April 24th, 1990, it’s shown us some incredible sights that we wouldn’t otherwise ever get to see. Recently, it sent back a new image of Jupiter with its moon Europa […]
