This Galaxy is 10 Billion Light Years Away, Visible Through a Cosmic Lens

Hubble, which just came back online after being down for a month, has captured this stunning photo of a galaxy that exists a staggering 10 billion light-years away. The telescope can see and focus this vast distance by leveraging the power of gravity.

This photo of MRG-M0138, what NASA describes as a “slumbering giant” which has run out of the gas that is required to form new stars, is framed by a smattering of visible galaxies and stars that arc in a circular pattern. The Hubble Space Telescope’s ability to see the vast distances is also the cause of this unique visual effect: gravitational lensing.

Earlier this year, NASA fully explained how gravitational lensing works in a detailed video, but in short gravitational lensing occurs when light from a distant galaxy is subtly distorted by the gravitational pull of an intervening astronomical object. Gravity distorts space in such a way that it makes an “optic” that channels light towards Hubble and gives it the ability to see galaxies that are normally too far away to be studied with current technology and physical telescopes. NASA describes it as akin to looking through a giant magnifying glass.

The centre of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant galaxies. Gravitational lensing occurs when light from a distant galaxy is subtly distorted by the gravitational pull of an intervening astronomical object. In this case, the relatively nearby galaxy cluster MACSJ0138.0-2155 has lensed a significantly more distant quiescent galaxy — a slumbering giant known as MRG-M0138 which has run out of the gas required to form new stars and is located 10 billion light years away.

“Astronomers can use gravitational lensing as a natural magnifying glass, allowing them to inspect objects like distant dormant galaxies which would usually be too difficult for even Hubble to resolve,” NASA explains.

NASA explains that this particular image was made using observations from eight different infrared filters spread across two of Hubble’s more advanced astronomical instruments: the Advanced Camera for Surveys and the Wide Field Camera 3. These two instruments were installed by technicians during Hubble’s last two servicing missions: Servicing Mission 3B which took place from March 1 through March 12 of 2002 and Servicing Mission 4, which took place between May 11 and May 24 2009.

“During SM4, two new scientific instruments were installed — the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3),” NASA explains.

The Advanced Camera for Surveys was installed on Servicing Mission 3B, but was considered a “failed instrument.” This was repaired during Servicing Mission 4.

“Two failed instruments, the Space Telescope Imaging Spectrograph (STIS) and the Advanced Camera for Surveys (ACS), were revived by the first-ever on-orbit repairs,” NASA continues. “With these efforts, Hubble was brought to the apex of its scientific capabilities.”

Hubble had been operating continuously for 31 years before an issue in June of 2021 nearly brought the satellite down. After a month of work, NASA was able to resolve the issue and keep the legendary telescope operational, and able to continue to capture some of the most breathtaking photos of the universe humans have ever seen.

10 Tips to Get the Best Results Photographing out of Helicopters

Aerial photography is a captivating and efficient way to showcase a client’s project, landscapes, or large-scale developments. In a recent shoot, I was commissioned to photograph 15-20 locations around Hong Kong. These varied from major highways, the Happy Valley racecourse, residential properties in Kennedy Town, container ports, Tsing Ma Bridge, and then over to Sheko Beach with a final hovering around Shatin.

Working from a helicopter is both exhilarating and challenging, it requires great communication and teamwork, with many variables being taken into consideration. The team at Hong Kong Heli services were outstanding. With an experienced pilot, we managed to rise high in the air to photograph just in time, given the weather condition that day.

Below are 10 tips for anyone who is looking to get the best results when taking photographs from a helicopter.

  • Shooting with the doors off is a must to get the angles you need and to shoot with an unrestricted view. Harnessed in, you can slide around in your seat, lean out, and feel the wind rush beneath you.
  • Take two cameras, one equipped with a zoom lens and the other with a wide-angle. My gear consists of two Sony Alpha 7R IV bodies, a Sony 70-200mm f/2.8, a Sony 16-35mm f/4, a spare Sony ALpha 9 body, and a 24-70 f/2.8. Some flights will allow you to change lenses once the door is closed, others won’t. Make sure your camera is anchored to you with camera straps.
  • When it comes to shutter speeds, keep them high. I recommend a minimum 1/1000 of a second which will ensure everything stays sharp. For my aperture, I ranged between f/2.8 and f/5.6, but it will depend on the weather and available light. Keep your ISO on auto. If the weather is changing a lot, then you may need to keep adjusting it accordingly.
  • Shoot in RAW, this gives you more flexibility to edit your images. I also suggest keeping your white balance set to auto.
  • Remove all lens hoods and anything else that may come off — safety is the most important thing!
  • As far as clothing is concerned, dress to the weather conditions and only take what you need. It is a cramped environment you don’t want to be getting tangled up in the headset, camera straps, inflatable life vest, etc. Before take-off, ensure your gear is sorted and easily accessible. In colder climates, a beanie and gloves are a must — the wind is a killer!
  • If you can choose the time of your flight, aim for early morning or late afternoon as this is generally the best light and you will have nice contrast and shadows from buildings. Shooting an hour before sunset would be my go-to time.
  • Plan your route! We spent an hour before the flight with the pilot to ensure we were all on the same page, and the actual planning for this job took several weeks. Allow a little extra time for the shoot (if you can), as things happen and sometimes you will need more time to get the shots you want.
  • Photograph inside the helicopter and whoever you are up in the air with, these are great memories to have and give a great perspective.
  • Make sure you have enough storage capacity for the photos you’re taking. I always have at least a 32GB or 64GB card in each of my cameras. The last thing you want to be doing is fussing around changing cards and missing shots. I always record to two cards to ensure the footage is saved twice.

There are obviously a lot more tips and tricks, but I hope this gives you a good look into what I did and experienced during one of my shoots. If you get the chance in Hong Kong to take a flight, do it! That bird’s eye view is something very special and gives you such a different perspective of the city we live in.
