The Sun: Abundant Sunspot Activity | NASA’s Solar Dynamics Observatory

The Sun: Abundant Sunspot Activity | NASA’s Solar Dynamics Observatory

An abundance of sunspot groups are present on the visible solar disk—at least 12 active regions. Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing, or reorganizing of magnetic field lines near sunspots. The southern solar hemisphere has the most and largest sunspot complexes at this time, to include the most likely flare sources: Regions 3738, 3743, and 3751. Region 3738 is the most magnetically complex, but growth has slowed and it will rotate out to the western solar limb by Wednesday, July 17, 2024.

R1-R2 (Minor-Moderate) solar flares remain likely between July 15-18, 2024.  

NASA’s Solar Dynamics Observatory captured these images of sunspot activity on July 13, 2024. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

A Surprising Ring 10 Billion Light Years Away: Galaxy PJ0116-24 | ESO

A Surprising Ring 10 Billion Light Years Away: Galaxy PJ0116-24 | ESO


This picture shows the distant galaxy PJ0116-24, a so-called Hyper Luminous Infrared Galaxy (HyLIRG). HyLIRGs are incredibly bright galaxies, lit up by the extremely rapid star formation within them. What triggers this?

Previous studies suggested that such extreme galaxies must result from galactic mergers. These galactic collisions are thought to create dense gas regions where rapid star formation is triggered. However,  isolated galaxies can also become HyLIRGs via internal processes alone, if star-forming gas is rapidly funneled towards the galaxy’s center.

In a new paper led by Daizhong Liu of the Max-Planck Institute for Extraterrestrial Physics, observations from the European Southern Observatory’s Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA) were combined to study the motion of gas within PJ0116-24. ALMA traces cold gas, seen here in blue, whereas the VLT, with its new Enhanced Resolution Imager and Spectrograph (ERIS), traces warm gas, shown in red. Thanks to these detailed observations, the team discovered that the gas in this extreme galaxy was rotating in an organized way, rather than in the chaotic way expected after a galactic collision––a surprising result! This shows convincingly that mergers are not always needed for a galaxy to become a HyLIRG.

PJ0116-24 is so far away that its light took about 10 billion years to reach us. Luckily, a foreground galaxy (not shown here) acted as a gravitational lens, bending and magnifying the light of PJ0116-24 behind it into the Einstein ring seen here. This precise cosmic alignment allows astronomers to zoom in on very distant objects and see them in a level of detail that would otherwise be very hard to achieve.

Dwarf Irregular Galaxy NGC 5238 in Canes Venatici | Hubble

Dwarf Irregular Galaxy NGC 5238 in Canes Venatici | Hubble


The galaxy featured in this Hubble picture is the dwarf irregular galaxy NGC 5238, located 14.5 million light-years from Earth in the constellation Canes Venatici. Its unexciting, blob-like appearance, resembling more an oversized star cluster than a galaxy, belies a complicated structure that has been the subject of considerable research. Here, the NASA/European Space Agency Hubble Space Telescope is able to pick out the galaxy’s countless stars, as well as its associated globular clusters— the glowing spots both inside and around the galaxy that contain ever more stars.

NGC 5238 is theorized to have recently—here meaning no more than a billion years ago—had a close encounter with another galaxy. The evidence for this is the tidal distortions of NGC 5238’s shape, the kind produced by two galaxies pulling on each other as they interact. There is no nearby galaxy that could have caused this disturbance, so the hypothesis is that the culprit is a smaller satellite galaxy that was devoured by NGC 5238. Traces of the erstwhile galaxy might be found by closely examining the population of stars in NGC 5238, a task for which the Hubble Space Telescope is an astronomer’s best tool. Two tell-tale signs would be groups of stars with properties that look out of place compared to most of the galaxy’s other stars, indicating that they were originally formed in a separate galaxy, or stars that look to have all formed abruptly at around the same time. This would occur during a galactic merger. The data used to make this image will be put to use in testing these predictions.

Despite their small size and unremarkable appearance, it is not unusual for dwarf galaxies like NGC 5238 to drive our understanding of galaxy formation and evolution. One main theory of galaxy evolution is that galaxies formed ‘bottom-up’ in a hierarchical fashion: star clusters and small galaxies were the first to form out of gas and dark matter, and they gradually were assembled by gravity into galaxy clusters and superclusters, explaining the shape of the very largest structures in the Universe today. A dwarf irregular galaxy like NGC 5238 merging with an even smaller companion is just the type of event that might have begun this process of galaxy assembly in the early Universe. So, it turns out that this tiny galaxy may serve as a testbed for the most fundamental predictions in astrophysics!

Image Description: A dwarf irregular galaxy. It appears as a cloud of bluish gas, filled with point-like stars that also spread beyond the edge of the gas. A few glowing red clouds sit near its center. Many other objects can be seen around it: distant galaxies in the background, four-pointed stars in the foreground, and star clusters that are part of the galaxy—shining spots surrounded by more tiny stars.

Spiral Galaxy NGC 5643 in Lupus | Hubble

Spiral Galaxy NGC 5643 in Lupus | Hubble


This image by the NASA/European Space Agency Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (The Wolf). It required thirty exposures for a total of 9 hours observation time to produce an image of such high detail and beauty.

NGC 5643 is about 60 million light-years away from Earth. It has been the host of a recent supernova event (not visible in this latest image). This supernova (2017cbv) involves a white dwarf star stealing so much mass from a companion star that it becomes unstable and explodes. The explosion releases significant amounts of energy and lights up that part of the galaxy.

The observation was proposed by Adam Riess. He was awarded a Nobel Laureate in physics 2011 for his contributions to the discovery of the accelerating expansion of the Universe, alongside Saul Perlmutter and Brian Schmidt.

Galaxy Cluster MACS J0416 | NASA Chandra, Hubble & Webb Space Telescopes

Galaxy Cluster MACS J0416 | NASA Chandra, Hubble & Webb Space Telescopes

This is a composite image from NASA’s Chandra X-ray Observatory, the Hubble Space Telescope, and the James Webb Space Telescope. Pictured is galaxy cluster MACS J0416 at a distance of about 4.3 billion light-years from Earth in the constellation Eridanus.

Galaxy clusters are the largest objects in the universe held together by gravity, and ones like this can contain hundreds or even thousands of individual galaxies all immersed in massive amounts of superheated gas that Chandra can detect. In this view, Chandra’s X-rays in purple show this reservoir of hot gas while Hubble and Webb pick up the individual galaxies in red, green, and blue. The long thin lines are caused by matter in the cluster distorting the light from galaxies behind MACS J0416 in a process known as gravitational lensing.

Image Description: Here, the blackness of space is packed with glowing dots and tiny shapes, in whites, purples, oranges, golds, and reds, each a distinct galaxy. Upon close inspection (and with a great deal of zooming in) spiraling arms of the seemingly tiny galaxies can be revealed in this highly detailed image. Gently arched across the middle of the frame is a soft band of purple—a reservoir of superheated gas detected by Chandra.

Galaxy NGC 3627 in Leo | NASA Chandra, Hubble & Webb Space Telescopes

This is a composite image from NASA’s Chandra X-ray Observatory, the Hubble Space Telescope, and the James Webb Space Telescope. Pictured is galaxy NGC 3627, located 36 million light-years away.

Like the Milky Way, NGC 3627 is a spiral galaxy that we see at a slight angle. NGC 3627 is known as a “barred” spiral galaxy because of the rectangular shape of its central region. From our vantage point, we can also see two distinct spiral arms that appear as arcs. X-rays from Chandra in purple show evidence for a supermassive black hole in its center as well as other dense objects like neutron stars and black holes pulling in matter. Meanwhile Webb finds the dust, gas, and stars throughout the galaxy in red, green, and blue. This image also contains optical data from NASA’s Hubble Space Telescope in red, green, and blue.

Image Description: A hazy image of a spiral galaxy known as NGC 3627. Here, the galaxy appears pitched at an oblique angle, tilted from our upper left down to our lower right. Much of its face is angled toward us, making its spiral arms, composed of red and purple dots, easily identifiable. Several bright white dots ringed with neon purple speckle the galaxy. At the galaxy’s core, where the spiral arms converge, a large white and purple glow identified by Chandra provides evidence of a supermassive black hole.

Orion Nebula | NASA Chandra & Webb Space Telescopes

Orion Nebula | NASA Chandra & Webb Space Telescopes


This is a composite image from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope. Pictured is the Orion Nebula, a giant cloud where stars are forming. Still located in the Milky Way galaxy, this region is a little bit farther from our home planet at about 1,500 light-years away. 

If you look just below the middle of the three stars that make up the “belt” in the constellation of Orion, you may be able to see this nebula through a small telescope. With Chandra and Webb, however, we get to see so much more. Chandra reveals young stars that glow brightly in X-rays, colored in red, green, and blue, while Webb shows the gas and dust in darker red that will help build the next generation of stars here.

Image Description: This is a peek into the heart of the Orion Nebula. It blankets the entire image. Here, the young star nursery resembles a dense, stringy, dusty rose cloud, peppered with thousands of glowing golden, white, and blue stars. Layers of cloud around the edges of the image, and a concentration of bright stars at its distant core, help convey the depth of the nebula.

This is a composite image from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope. Pictured is Rho Ophiuchi, at a distance of about 390 light-years from Earth. Rho Ophiuchi is a cloud complex filled with gas and stars of varying sizes and ages. Being one of the closest star-forming regions, Rho Ophiuchi is a great place for astronomers to study young stars. In this image, X-rays from Chandra are purple and reveal the hot, outer atmospheres of infant stars. Infrared data from Webb's NIRCam is red, yellow, cyan, light blue, and darker blue and provides views of the spectacular regions of gas and dust.

Image Description: The murky green and gold cloud resembles a ghostly head in profile, swooping down from the upper left, trailing tendrils of hair. Cutting across the bottom edge and lower righthand corner of the image is a long, narrow, brick red cloud which resembles the ember of a stick pulled from a fire. Several large white stars dot the image. Many are surrounded by glowing neon purple rings, and gleam with diffraction spikes.

Asteroid Photobombs Hubble Snapshot of Galaxy UGC 12158

Asteroid Photobombs Hubble Snapshot of Galaxy UGC 12158


This NASA/European Space Agency Hubble Space Telescope image of the barred spiral galaxy UGC 12158 looks like someone took a white marking pen to it. In reality it is a combination of time exposures of a foreground asteroid moving through Hubble’s field of view, photobombing the observation of the galaxy. Several exposures of the galaxy were taken, which is evidenced by the dashed pattern.

Distance of galaxy UGC 12158 to Earth: 400 million light years

The asteroid appears as a curved trail as a result of parallax: Hubble is not stationary, but orbiting Earth, and this gives the illusion that the faint asteroid is swimming along a curved trajectory. The uncharted asteroid is inside the asteroid belt in our Solar System, and hence is 10 trillion times closer to Hubble than the background galaxy.

Rather than being a nuisance, this type of data is useful to astronomers for doing a census of the asteroid population in our Solar System.

Image Description: This is a Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape made up of bright blue stars wound around a yellow-white hub of central stars. The hub has a slash of stars across it, called a bar. The galaxy is tilted face-on to our view from Earth. A slightly S-shaped white line across the top is the Hubble image of an asteroid streaking across Hubble’s view. It looks dashed because the image is a combination of several exposures of the asteroid flying by like a race car.

Barred Spiral Galaxy UGC 12158 in Pegasus | Hubble

Barred Spiral Galaxy UGC 12158 in Pegasus | Hubble


The galaxy captured in this image, called UGC 12158, is not camera-shy. This spiral stunner is posing face-on to the NASA/European Space Agency Hubble Space Telescope’s Advanced Camera for Surveys, revealing its structure in fine detail.

UGC 12158 is an excellent example of a barred spiral galaxy in the Hubble sequence—a scheme used to categorize galaxies based on their shapes. Barred spirals, as the name suggest, feature spectacular swirling arms of stars that emanate from a bar-shaped center. Such bar structures are common, being found in about two thirds of spiral galaxies, and are thought to act as funnels, guiding gas to their galactic centers where it accumulates to form newborn stars. These are not permanent structures: astronomers think that they slowly disperse over time, so that the galaxies eventually evolve into regular spirals.

The appearance of a galaxy changes little over millions of years, but this image also contains a short-lived and brilliant interloper—the bright blue star just to the lower left of the center of the galaxy is very different from the several foreground stars seen in the image. It is in fact a supernova inside UGC 12158 and much further away than the Milky Way stars in the field—at a distance of about 400 million light-years! This stellar explosion, called SN 2004ef, was first spotted by two British amateur astronomers in September 2004 and the Hubble data shown here form part of the follow-up observations.

This picture was created from images taken with the Wide Field Channel of Hubble’s Advanced Camera for Surveys. Images through blue (F475W, colored blue), yellow (F606W, colored green) and red (F814W, colored red) as well as a filter that isolates the light from glowing hydrogen (F658W, also colored red) have been included. The exposure times were 1160 s, 700 s, 700 s and 1200 s respectively. The field of view is about 2.3 arcminutes across.
