Sun Releases Largest Flare in Nearly a Decade | NASA Goddard

Sun Releases Largest Flare in Nearly a Decade | NASA Goddard

On May 14, 2024, the Sun emitted a strong solar flare. This solar flare is the largest of Solar Cycle 25 and is classified as an X8.7 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

A solar flare is an intense burst of radiation, or light, on the Sun. Flares are our solar system’s most powerful explosive events. Light only takes about 8 minutes to travel from the Sun to Earth, so that’s how long it would take the energy from a flare to reach our planet. Stronger solar flares—those rated class M5 or above—can have impacts on technology that depends on Earth’s ionosphere (our electrically charged upper atmosphere), like high-frequency radio used for navigation and GPS.

NASA’s Solar Dynamics Observatory (SDO) captured these images of the flare, which peaked at 12:51 p.m. ET on May 14. The X8.7 flare appears on the lower right edge of the Sun. (A small eruption appears afterward in the upper left.) SDO sees the Sun in more than 10 distinct wavelengths of light, showing solar material at different temperatures. Different wavelengths are shown in this video to highlight different features of the flare.

Jupiter’s Tiny Moon Amalthea | NASA Juno Mission

Jupiter’s Tiny Moon Amalthea | NASA Juno Mission

NASA’s Juno mission captured these views of Jupiter during its 59th close flyby of the giant planet on March 7, 2024. They provide a good look at Jupiter’s colorful belts and swirling storms, including the Great Red Spot. Close examination reveals something more: two glimpses of the tiny moon Amalthea.

With a radius of just 52 miles (84 kilometers), Amalthea has a potato-like shape, lacking the mass to pull itself into a sphere. In 2000, NASA’s Galileo spacecraft revealed surface features, including impact craters, hills, and valleys. Amalthea circles Jupiter inside Io’s orbit, which is the innermost of the planet’s four largest moons, taking 0.498 Earth days to complete one orbit.

Amalthea is the reddest object in the solar system, and observations indicate it gives out more heat than it receives from the Sun. This may be because, as it orbits within Jupiter’s powerful magnetic field, electric currents are induced in the moon’s core. Alternatively, the heat could be from tidal stresses caused by Jupiter’s gravity.

At the time that the first of these two images was taken, the Juno spacecraft was about 165,000 miles (265,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 5 degrees north of the equator.

Citizen scientist Gerald Eichstädt made these images using raw data from the JunoCam instrument, applying processing techniques to enhance the clarity of the images.

Young Triple-star System: HP Tau, HP Tau G2 & HP Tau G3 | Hubble

Young Triple-star System: HP Tau, HP Tau G2 & HP Tau G3 | Hubble

Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in this new image from NASA’s Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that has not begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun. T Tauri stars tend to be younger than 10 million years old―in comparison, our Sun is around 4.6 billion years old―and are often found still swaddled in the clouds of dust and gas they were formed from.

As with all variable stars, HP Tau’s brightness changes over time. T Tauri stars are known to have periodic and random fluctuations in brightness. The random variations may be due to the chaotic nature of a developing young star, such as instabilities in the accretion disk of dust and gas around the star, material from that disk falling onto the star and being consumed, and flares on the star’s surface. The periodic changes may be due to giant sunspots rotating in and out of view.

Curving around the stars, a cloud of gas and dust shines with their reflected light. Reflection nebulae do not emit visible light of their own, but shine as the light from nearby stars bounces off the gas and dust, like fog illuminated by the glow of a car’s headlights.

HP Tau is located approximately 550 light-years away in the constellation Taurus. Hubble studied HP Tau as part of an investigation into protoplanetary disks, the disks of material around stars that coalesce into planets over millions of years.

Aurora Generator: Active Solar Region AR 3664 at Sunset in Rome, Italy

Aurora Generator: Active Solar Region AR 3664 at Sunset in Rome, Italy

A distant Sun is seen over water and between foreground trees. On the lower part of the setting Sun is the gigantic active region AR 3664 visible by its dark sunspots a few days ago from Civitavecchia, Rome, Italy. Active region AR 3664 is larger than the Earth. It is so big you could actually see it on the Sun's surface without magnification. It contains powerful and tangled magnetic fields, as well as numerous dark sunspots. Labelled AR 3664, it developed into one of the most energetic areas seen on the Sun in recent years, unleashing a series of explosions that led to a surge of energetic particles striking the Earth. This created beautiful auroras. It may continue. 

The Sun rotates (once every 27 days). AR 3664 is now rotating away from the Earth, although the region may survive long enough to come around again. Active regions on the Sun, like AR 3664, can be quite dangerous. However, this region's coronal mass ejections (CMEs) have not created, as of yet, much damage to Earth-orbiting satellites or to electrical grids on the Earth's surface.  

This composite image includes a very short exposure taken of just the Sun's surface. It mimics what was actually visible.

Gum 46: A Bubblegum-pink Nebula | European Southern Observatory

Gum 46: A Bubblegum-pink Nebula | European Southern Observatory

This picture shows Gum 46, a stunning gas cloud 5,500 light-years away, observed in brand new detail with the European Southern Observatory’s Very Large Telescope (VLT) in Chile. 

Why does it glow pink?

At the heart of Gum 46 there’s a young, hot, and blue star called HD311999. Its intense radiation excites atoms in the surrounding gas. It then re-emits this energy at very specific colors or wavelengths. The pink shade that dominates this image is due to hydrogen atoms, the most abundant element in this nebula and the Universe as a whole.

The dark wispy clouds that surround the nebula make for a stunning sight too. These clouds are not intrinsically dark. They are extremely dense regions of dust that block light passing through them, enshrouding the glowing heart of Gum 46.

This image was created as part of the European Southern Observatory (ESO) Cosmic Gems program, an outreach initiative to produce images of interesting, intriguing or visually attractive objects using ESO telescopes, for the purposes of education and public outreach. The program makes use of telescope time that cannot be used for science observations. All data collected may also be suitable for scientific purposes, and are made available to astronomers through ESO’s science archive.

NASA’s New Mobile Launcher for Artemis Moon Missions | Kennedy Space Center

NASA’s New Mobile Launcher for Artemis Moon Missions | Kennedy Space Center

The foundation is set at NASA’s Kennedy Space Center in Florida for launching crewed missions aboard the agency’s larger and more powerful Space Launch System (SLS) Block 1B rocket in support of Artemis IV and future missions. On May 9, 2024, teams with NASA’s Exploration Ground Systems (EGS) Program and contractor Bechtel National Inc. transferred the primary base structure of the mobile launcher 2 to its permanent mount mechanisms using the spaceport’s beast-mode transporter—the crawler for assembly.

The 355-foot-tall mobile launcher 2 with a two-story base and a tower will be used to assemble and process the SLS rocket and Orion spacecraft in the Vehicle Assembly Building on NASA’s upcoming Artemis missions to the Moon beginning with Artemis IV.

“Seeing mobile launcher 2 take shape has been incredible,” said Shawn Quinn, program manager for NASA’s EGS Program. “Anytime we can see the manifestation of our work into physical hardware means a lot to the EGS team. It is also inspiring for the future of Artemis, with each bolt and truss put in place signifying the next phase of humanity’s return to the Moon.” 

Why is the “Jack & Set” process necessary?

Teams at Bechtel fabricated temporary pedestals 8 feet off the ground, facilitating a much more efficient and safer initial steel build process by sitting lower to the ground. These extremely large steel truss subassemblies, a number weighing over 100,000 pounds each, sat on temporary bases. Once the entire 2.6 million-pound skeleton of the base was fully torqued and welded, teams used a specialized heavy-duty jacking system to raise the base to allow sufficient space for the spaceport’s crawler to be situated underneath the structure ahead of repositioning. 

Four self-propelled modular transporters were driven underneath the sides of the steel assembly and then lowered the base onto eight surrounding jacks. Once secured, teams removed the transporters and used jacks to raise the base 18 feet to allow for crawler access underneath the structure. The crawler was then positioned under the new base skeleton, raised the structure a few inches higher, and repositioned it about 200 feet to the six permanent pedestals, called mount mechanisms, completing the “jack and set” operation.  

“The jack & set milestone is a huge accomplishment for the NASA and Bechtel team,” said Darrell Foster, ground systems integration manager for NASA’s EGS Program.  “It represents the hard work of hundreds of people—not only in the field putting the pieces together, but engineers and analysts who custom designed this structure, subcontracting buyers and delivery managers who drove the process to get the materials to the site, and the several offsite fabrication shops across the country.”  

Now poised atop the new launch mount mechanisms at its park site near the spaceport’s Vehicle Assembly Building, teams will begin installing critical piping and electrical equipment inside the base. The mobile launcher will remain at the park site throughout the build and commissioning phases of the project. 

The mobile launcher serves as the primary interface between the ground launch systems, SLS rocket, and Orion spacecraft that will launch the SLS Block 1B rocket, with its enhanced upper stage, to the Moon, allowing the agency to send astronauts and heavier cargo into lunar orbit than its predecessor, SLS Block 1. With Artemis, NASA will land the first woman, first person of color, and its first international partner astronaut on the lunar surface and establish long-term exploration for scientific discovery and to prepare for human missions to Mars.

The Northern Lights at Étretat, France

The Northern Lights at Étretat, France

Astrophotographer Julien Looten: "So here is a panorama composed of 25 images. Stitching the panorama was not an easy task, given the rapid movement of the auroral pillars and the difficulty in finding landmarks between photos. The panorama spans from southwest (left) to northeast, covering 180 degrees, once again demonstrating the magnitude of the aurora at that time. The colors range from pink to purple, through blue, while a greenish band is visible lower towards the horizon. In the upper right corner, you can also see the Milky Way (our galaxy) and the constellation of Cygnus. The greenish glows to the right are due to the light pollution from Étretat. The foreground corresponds to the cliffs of Étretat, one of the natural wonders of the French territory (latitude 49.43). On the left, another photographer is at work."

Étretat is a commune in the Seine-Maritime department in the Normandy region of Northwestern France. It is located on the coast of the Pays de Caux area. Étretat is best known for its chalk cliffs, including three natural arches and a pointed formation called L'Aiguille or the Needle, which rises 70 metres (230 ft) above the sea.

Exploring Planet Uranus | NASA Goddard

Exploring Planet Uranus | NASA Goddard

In one of the least explored regions of our solar system, there is an ice giant that scientists believe can help us unlock some of the remaining mysteries of our universe. This video takes us on a journey there to explore planet Uranus, as well as its rings and moons, highlighting many fascinating features.

We also look back on what was discovered by NASA's Voyager 2 spacecraft, as well as subsequent findings by ground-based telescopes and the Hubble Space Telescope. The ongoing search for ocean worlds and life beyond Earth makes Uranus an exciting target for the James Webb Space Telescope and for future up-close exploration.

Madrid Deep Space Network Reaches NASA's Voyager 1 across 24 billion kilometers

Madrid Deep Space Network Reaches NASA's Voyager 1 across 24 billion kilometers

"By Their Powers Combined": This April 20, 2024, image shows a first—all six radio frequency antennas at the Madrid Deep Space Communication Complex in Spain, part of NASA’s Deep Space Network (DSN), carried out a test to receive data from the agency’s Voyager 1 spacecraft (1977-2024) at the same time.

Combining the antennas’ receiving power, or arraying, lets the DSN collect the very faint signals from faraway spacecraft. Voyager 1 is over 15 billion miles (24 billion kilometers) away, so its signal on Earth is far fainter than any other spacecraft that the DSN communicates with. It currently takes Voyager 1’s signal over 22 ½ hours to travel from the spacecraft to Earth. To better receive Voyager 1’s radio communications, a large antenna—or an array of multiple smaller antennas—can be used. A five-antenna array is currently needed to downlink science data from the spacecraft’s Plasma Wave System (PWS) instrument. As Voyager gets further way, six antennas will be needed.

The twin Voyager 1 and 2 spacecraft are still operating and traveling where no spacecraft—or anything touched by humanity—has gone before. As we celebrate the 47th anniversary of the Voyager 1 launch later this year, we will again reflect on the vision that inspired the mission, its greatest achievements, and its enduring legacy.
