The Hubble Ultra Deep Field of nearly 10,000 galaxies is the deepest visible-light image of the cosmos. The image required 800 exposures taken over 400 Hubble orbits around Earth. The total amount of exposure time was 11.3 days, taken between Sept. 24, 2003 and Jan. 16, 2004. Credits:
NASA, ESA, S. Beckwith (STScI) and the HUDF Team With the help of NASA’s Hubble Space Telescope, an international team of researchers led by scientists in the Department of Astronomy at Stockholm University has found more black holes in the early universe than has previously been reported. The new result can help scientists understand how supermassive black holes were created.
Currently, scientists do not have a complete picture of how the first black holes formed not long after the big bang. It is known that supermassive black holes, that can weigh more than a billion suns, exist at the center of several galaxies less than a billion years after the big bang.
“Many of these objects seem to be more massive than we originally thought they could be at such early times — either they formed very massive or they grew extremely quickly,” said Alice Young, a PhD student from Stockholm University and co-author of the study published in The Astrophysical Journal Letters.
This is a new image of the Hubble Ultra Deep Field. The first deep imaging of the field was done with Hubble in 2004. The same survey field was observed again by Hubble several years later, and was then reimaged in 2023. By comparing Hubble Wide Field Camera 3 near-infrared exposures taken in 2009, 2012, and 2023, astronomers found evidence for flickering supermassive black holes in the hearts of early galaxies. One example is seen as a bright object in the inset. Some supermassive black holes do not swallow surrounding material constantly, but in fits and bursts, making their brightness flicker. This can be detected by comparing Hubble Ultra Deep Field frames taken at different epochs. The survey found more black holes than predicted.

Black holes play an important role in the lifecycle of all galaxies, but there are major uncertainties in our understanding of how galaxies evolve. In order to gain a complete picture of the link between galaxy and black hole evolution, the researchers used Hubble to survey how many black holes exist among a population of faint galaxies when the universe was just a few percent of its current age.
Initial observations of the survey region were re-photographed by Hubble after several years. This allowed the team to measure variations in the brightness of galaxies. These variations are a telltale sign of black holes. The team identified more black holes than previously found by other methods.
The new observational results suggest that some black holes likely formed by the collapse of massive, pristine stars during the first billion years of cosmic time. These types of stars can only exist at very early times in the universe, because later-generation stars are polluted by the remnants of stars that have already lived and died. Other alternatives for black hole formation include collapsing gas clouds, mergers of stars in massive clusters, and “primordial” black holes that formed (by physically speculative mechanisms) in the first few seconds after the big bang. With this new information about black hole formation, more accurate models of galaxy formation can be constructed.
“The formation mechanism of early black holes is an important part of the puzzle of galaxy evolution,” said Matthew Hayes from the Department of Astronomy at Stockholm University and lead author of the study. “Together with models for how black holes grow, galaxy evolution calculations can now be placed on a more physically motivated footing, with an accurate scheme for how black holes came into existence from collapsing massive stars.”
Image Before/After Astronomers are also making observations with NASA’s James Webb Space Telescope to search for galactic black holes that formed soon after the big bang, to understand how massive they were and where they were located.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Sols 4304-4006: 12 Years, 42 Drill Holes, and Now… 1 Million ChemCam Shots!
In celebration of ChemCam’s milestone, here is a stunning image from its remote micro imager, showing details in the landscape far away. This image was taken by Chemistry & Camera (ChemCam) onboard NASA’s Mars rover Curiosity on Sol 4302 — Martian day 4,302 of the Mars Science Laboratory mission — on Sept. 12, 2024, at 09:20:51 UTC. NASA/JPL-Caltech Earth planning date: Friday, Sept. 13, 2024
Today, I need to talk about ChemCam, our laser and imaging instrument on the top of Curiosity’s mast. It one of the instruments in the “head” that gives Curiosity that cute look as if it were looking around tilting its head down to the rocks at the rover’s wheels. On Monday, 19th August the ChemCam team at CNES in France planned the 1 millionth shot and Curiosity executed it on the target Royce Lake on sol 4281 on Mars. Even as an Earth scientist used to really big numbers, this is a huge number that took me a while to fully comprehend. 1 000 000 shots! Congratulations, ChemCam, our champion for getting chemistry from a distance – and high-resolution images, too. If you are now curious how Curiosity’s ChemCam instrument works, here is the NASA fact sheet. And, of course, the team is celebrating, which is expressed by those two press releases, one from CNES in France and one from Los Alamos National Laboratory, the two institutions who collaborated to develop and build ChemCam and are now running the instrument for over 12 years! And the PI, Dr Nina Lanza from Los Alamos informs me that the first milestone – 10000 shots was reached as early as Sol 42, which was the sol the DAN instrument used its active mode for the first time. But before I am getting melancholic, let’s talk about today’s plan!
The drive ended fairly high up in the terrain, and that means we see a lot of the interesting features in the channel and generally around us. So, we are on a spot a human hiker would probably put the backpack down, take the water bottle out and sit down with a snack to enjoy the view from a nice high point in the landscape. Well, no such pleasures for Curiosity – and I am pretty sure sugar, which we humans love so much, wouldn’t be appreciated by rover gears anyway. So, let’s just take in the views! And that keeps Mastcam busy taking full advantage of our current vantage point. We have a terrain with lots of variety in front of us, blocks, boulders, flatter areas and the walls are layered, beautiful geology. Overall there are 11 Mastcam observations in the plan adding up to just about 100 individual frames, not counting those taken in the context of atmospheric observations, which are of course also in the plan. The biggest mosaics are on the targets “Western Deposit,” “Balloon Dome,” and “Coral Meadow.” Some smaller documentation images are on the targets “Wales Lake,” “Gnat Meadow,” and “Pig Chute.”
ChemCam didn’t have long to dwell on its milestone, as it’s busy again today. Of course, it will join Mastcam in taking advantage of our vantage point, taking three remote micro imager images on the landscape around us. LIBS chemistry investigations are targeting “Wales Lake,” “Gnat Meadow,” and “Pig Chute.” APXS is investigating two targets, “College Rock” and “Wales Lake,” which will also come with MAHLI documentation. With all those investigations together, we’ll be able to document the chemistry of many targets around us. There is such a rich variety of dark and light toned rocks, and with so much variety everywhere, it’s hard to choose and the team is excited about the three targeted sols … and planning over 4 hours of science over the weekend!
The next drive is planned to go to an area where there is a step in the landscape. Geologists love those steps as they give insights into the layers below the immediate surface. If you have read the word ‘outcrop’ here, then that’s what that means: access to below the surface. But there are also other interesting features in the area, hence we will certainly have an interesting workspace to look at! But getting there will not be easy as the terrain is very complex, so we cannot do it in just one drive. I think there is a rule of thumb here: the more excited the geo-team gets, the more skills our drivers need. Geologists just love rocks, but of course, no one likes driving offroad in a really rocky terrain – no roads on Mars. And right now, our excellent engineers have an extra complication to think about: they need to take extra care where and how to park so Curiosity can actually communicate with Earth. Why? Well, we are in a canyon, and those of you liking to hike, know what canyons mean for cell phone signals… yes, there isn’t much coverage, and that’s the same for Curiosity’s antenna. This new NASA video has more information and insights into the planning room, too! So, we’ll drive halfway to where we want to be but I am sure there will be interesting targets in the new workspace, the area is just so, so complex, fascinating and rich!
And that’s after Mars for you, after 12 years, 42 drill holes, and now 1 Million ChemCam shots. Go Curiosity go!!!
