Hubble Images a Grand Spiral
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 5643. ESA/Hubble & NASA, A. Riess, D. Thilker, D. De Martin (ESA/Hubble), M. Zamani (ESA/Hubble) This NASA/ESA Hubble Space Telescope image features the glorious spiral galaxy NGC 5643, which is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy’s symmetrical form with two large, winding spiral arms that are clearly visible. Bright-blue stars define the galaxy’s spiral arms, along with lacy reddish-brown dust clouds and pink star-forming regions.
As fascinating as the galaxy appears at visible wavelengths, some of NGC 5643’s most interesting features are invisible to the human eye. Ultraviolet and X-ray images and spectra of NGC 5643 show that the galaxy hosts an active galactic nucleus: an especially bright galactic core powered by a feasting supermassive black hole. When a supermassive black hole ensnares gas from its surroundings, the gas collects in a disk that heats up to hundreds of thousands of degrees. The superheated gas shines brightly across the electromagnetic spectrum, but especially at X-ray wavelengths.
NGC 5643’s active galactic nucleus isn’t the brightest source of X-rays in the galaxy, though. Researchers using ESA’s XMM-Newton discovered an even brighter X-ray-emitting object, called NGC 5643 X-1, on the galaxy’s outskirts. What could be a more powerful source of X-rays than a supermassive black hole? Surprisingly, the answer appears to be a much smaller black hole! While the exact identity of NGC 5643 X-1 is unknown, evidence points to a black hole that is about 30 times more massive than the Sun. Locked in an orbital dance with a companion star, the black hole ensnares gas from its stellar companion, creating a superheated disk that outshines the NGC 5643’s galactic core.
NGC 5643 was also the subject of a previous Hubble image. The new image incorporates additional wavelengths of light, including the red color that is characteristic of gas heated by massive young stars.

Hubble Spots a Grand Spiral of Starbursts
The glittering NASA/ESA Hubble Space Telescope image is of the spiral galaxy NGC 5248, also known as Caldwell 45. ESA/Hubble & NASA, F. Belfiore, J. Lee and the PHANGS-HST Team The sparkling scene depicted in this NASA/ESA Hubble Space Telescope image is of the spiral galaxy NGC 5248, located 42 million light-years from Earth in the constellation Boötes. It is also known as Caldwell 45. The Caldwell catalog holds visually interesting celestial objects that are not as commonly observed by amateur astronomers as the more famous Messier objects.
NGC 5248 is one of the so-called ‘grand design’ spirals, with prominent spiral arms that reach from near the core out through the disk. It also has a faint bar structure at its center, between the inner ends of the spiral arms, which is not quite so obvious in this visible-light portrait from Hubble. Features like these which break the rotational symmetry of a galaxy have a huge influence on how matter moves through it, and eventually its evolution through time. They feed gas from a galaxy’s outer reaches to inner star-forming regions, and even to a galaxy’s central black hole where it can kick-start an active galactic nucleus.
These flows of gas have shaped NGC 5248 in a big way; it has many bright ‘starburst regions’ of intense star formation spread across its disk, which a population of young stars dominates. The galaxy even has two very active, ring-shaped starburst regions around its nucleus, filled with young clusters of stars. These ‘nuclear rings’ are remarkable enough, but normally a nuclear ring tends to block gas from getting further into the core of a galaxy. NGC 5248 having a second ring inside the first is a marker of just how forceful its flows of matter and energy are! Because the galaxy is relatively nearby, its highly visible starburst regions make the galaxy a target for professional and amateur astronomers alike.

“NASA has studied Earth and our changing climate for more than 60 years. The Earth Information Center at the Smithsonian Museum of Natural History will expand access to NASA’s data and our decades of Earth observation to even more people,” said Nelson. “Together with the Smithsonian, we are providing detailed, usable, and scalable information to enable the public to better understand the climate crisis and take action in their community.”
The exhibit includes a 32-foot-long, 12-foot-high video wall displaying Earth science data visualizations and videos, interpretive panels showing Earth’s connected systems, information on our changing world, and an overview of how NASA and the Smithsonian study our home planet. It opens to the public Tuesday, Oct. 8.
“The new Earth Information Center at the National Museum of Natural History will bring Smithsonian and NASA data on the Earth’s environment and climate to thousands of museum visitors every year,” said Kirk Johnson, the museum’s Sant director. “It is an honor to partner with NASA to bring this dynamic view of Earth to museumgoers and connect people more deeply with their home planet.”
Visitors also can explore Earth observing missions, changes in Earth’s landscape over time, and how climate is expected to change regionally through multiple interactive experiences. The exhibit will remain on display through 2028.
“The Earth Information Center allows people to see our planet as we at NASA see it – an awe-inspiring and complex system of oceans, land, ice, atmosphere, and the life they support,” said Karen St. Germain, division director, Earth Sciences Division at NASA Headquarters in Washington. “We are thrilled that this collaboration puts NASA’s Earth science at the fingertips of Smithsonian visitors for the benefit of all.”
With more than two dozen missions in orbit, NASA observes our planet’s oceans, land, ice, and atmosphere, and measure how a change in one drives change in others. NASA develops new ways to build long-term data records of how our planet evolves. The agency freely shares this unique knowledge and works with institutions around the world.
As part of NASA’s ongoing mission to better understand our home planet, NASA created the Earth Information Center which draws insights from across all NASA centers and its federal partners – the National Oceanic and Atmospheric Administration, U.S. Geological Survey, U.S. Department of Agriculture, U.S. Agency for International Development, Environmental Protection Agency, and Federal Emergency Management Administration. It allows viewers to see how our home planet is changing and gives decision makers information to develop the tools they need to mitigate, adapt, and respond to those changes.
NASA’s Earth Information Center is a virtual and physical space designed to aid people to make informed decisions on Earth’s environment and climate. It provides easily accessible Earth information, enabling global understanding of our changing planet.
The expansion of the physical Earth Information Center at the Smithsonian National Museum of Natural History makes it the second location in the Washington area. The first is located at NASA Headquarters in Washington at 300 E St., SW.

Sols 4289-4290: From Discovery Pinnacle to Kings Canyon and Back Again
This image shows the workspace in front of NASA’s Mars rover Curiosity, taken by the Left Navigation Camera aboard the rover on sol 4287 — Martian day 4,287 of the Mars Science Laboratory mission — on Aug. 28, 2024, at 02:23:27 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Aug. 28 2024
We are back … almost, anyways. Today’s parking location is very close to where we parked on sol 4253, and in an area near one of the previous contact science targets “Discovery Pinnacle.” You can read in this blog post that most of the team, this blogger included, was in Pasadena for our team meeting when we were last in this area. That was July and Curiosity was about to turn 12 on Mars. Coming back is a very rare occasion and is always planned carefully. Once or twice during the last 12 years it happened because we saw something “in the rear mirror.” One of the examples is the target “Old Soaker,” where we spotted mud cracks in the images from a previous parking position, and promptly went back because this was such an important discovery. At other times it was carefully planned, such as the “walkabout” at “Pink Cliffs,” which you can watch in this video from as long back as Earth year 2015. In the past few planning cycles, it’s more of the latter as we made our way from Discovery Pinnacle, where we were on sol 4253, “Just passing through” “Russell Pass” and arriving at “Kings Canyon,” our drill location, which we reached on sol 4257. You can follow all the action of the drilling at Kings Canyon on the blogs. It took a while — it always does — because it’s an activity with many steps and investigations to complete. We actually celebrated Curiosity’s 12th birthday at Kings Canyon! We departed on sol 4283, came back via “Cathedral Peak,” and are now near the Discovery Pinnacle location again. After that little walkabout through the history of (some) of Curiosity’s walkabouts, especially the very last one, let’s look at today’s plan.
It is a pretty normal two-sol plan, with a one-hour science block before we drive away from this location. We were greeted by a nicely flat surface, and the engineers informed us that we have all six wheels firmly on flat and stable ground. That’s always a relief, because only then can we use the arm. That nice piece of flat rock Curiosity is so firmly parked on became our science target …well, mostly. Some of the little pebbles on the surface attracted our attention, too. The very eagle-eyed can spot a small white spot in the image above. It’s right between the arm and the rover itself, about where the C is written. That’s a rock that we likely broke up with our wheel and that has a very white part to it. We called it “Thousand Island Lake,” and will image it with MAHLI. APXS is investigating a target called “Eichorn Pinnacle,” squarely on the big flat area. LIBS is also making the most of the large target underneath and in front of us, investigating the target “Nine Lakes Basin.”
In recent blogs you will have read about the dust-storm watch making the atmospheric investigations even more important, so we don’t miss any changes. We are looking for dust devils, atmospheric opacity, and are of course monitoring the weather throughout the plan.
Our drive will hopefully — if Mars agrees — be a long one, and we will also plan an activity that we call MARDI sidewalk. That’s when we take very frequent pictures with the MARDI instrument while driving. This results in a long strip of images nicely showing the nature of the terrain the rover has driven over. This is in addition to the MARDI single frame we are taking every time the rover stops. I often get the question, why are we taking an image just downwards whenever the rover stops? Well, humans are easy to bias toward the outliers, toward the things that look special, and of course the Curiosity team is no exception. For some things this is great, because it allows for the discoveries of new things. But it doesn’t provide an unbiased overview. That’s what MARDI does: It always points down and reliably records the terrain under the rover. We don’t have to do anything but put the commands for that one image into our plan after the drive — something that’s pretty routine after 12 years now!
