Data revealed from three small satellites make up NASA’s mission EZIE (Electrojet Zeeman Imaging Explorer) to unravel the mysteries in the surroundings of the auroral electrojet. Launched from California on March 14, 2025, the three satellites of NASA’s EZIE mission have officially begun their journey above the Earth’s atmosphere. The early observations coming in are already proving to be incredibly valuable in helping scientists better understand Earth’s auroral electrojets, they say. NASA says this is the first mission to study this electrical current in both northern and southern polar regions.

Study of EZIE Mission

After the launch of NASA’s EZIE Mission, these three CubeSats are now orbiting in a pearl-on-a-string form, 260 to 370 miles high from the Earth’s surface, to map the auroral electrojets. The EZIE team is excited to see the first light results, said the leader of the team, Sam Yee, of the Johns Hopkins Applied Physics Laboratory. Observations revealed it is clear that the spacecraft and the MEM instrument are both working as per the expectations.

What is MEM?

It is known as the Microwave Electroject Magnetogram, which measures the Zeeman splitting phenomenon. This will offer NASA the insight to study the evolution of electrojets with its structure, which has not been done previously.

Understanding the Auroral Electrojets

The Auroral electrojets are created by the massive energy shifted by the solar atmospheric pressure when it hits the atmosphere of the Earth. The electrojets emit an electrical charge of 1 million amps every second around the Earth’s magnetic poles. Magnetic disturbances of the Earth are created when these electrojets flow above the ground at around 65 miles. This could be a threat to the safety of astronauts and interfere with the satellites. This is the reason why knowing these electrojets is crucial for scientists.

Future of the Study

The mission has been funded by the Heliophysics Division at NASA. EZIE is managed by Goddard Space Flight Centre. A team of researchers will do the final analysis of the observations by EZIE, which will unveil the Earth and Space interlinking.

New Study Reveals How Jupiter’s Storms Hide Ammonia

New Study Reveals How Jupiter’s Storms Hide Ammonia

Jupiter’s weather just got even stranger. A new study published in the Journal Science Advances revealed that the gas giant’s turbulent thunderstorms create massive, softball-sized hailstones called “mushballs,” made of ammonia and water ice. These violent storms churn Jupiter’s atmosphere so deeply that they may explain a long-standing mystery among the scientists: the missing ammonia in the planet’s upper layers. For years, scientists were puzzled over why deep pockets of ammonia seemed absent across Jupiter’s atmosphere.

Mushballs Shake Up Old Assumptions

As per a report by LiveScience, Scientists believed Jupiter’s atmosphere was well mixed, much like a pot of boiling water. However, after analysing a massive 2017 storm captured by Juno, researchers found that even local storms can punch ammonia deep into the planet, shattering the old assumption. “The top of the atmosphere is actually a pretty poor representation of what the whole planet looks like,” explained study lead author Chris Moeckel from the University of California, Berkeley, told the publication. On April 15, 2025, as per EarthSky, his team’s findings suggest that the atmosphere becomes well-mixed only much deeper down than previously thought.

Ammonia as a Tracer Beneath the Clouds

Jupiter’s thick cloud cover blocks direct observation, and ammonia acts as a critical tracer to understand the hidden activity beneath the clouds. Scientists theorised in 2020 that Jupiter’s powerful storms lift ammonia-rich ice particles to high altitudes, where they combine with water ice to create a mushy, slushy hailstone. These mushballs then grow larger and heavier, cycling up and down in the atmosphere before plunging deep, carrying ammonia and water with them. This process leaves the upper atmosphere depleted, matching observations from Juno.

Confirmation came during Juno’s February 2017 flyby. While passing over a storm zone, the spacecraft detected an unexpected deep signal rich in ammonia and water beneath the storm clouds. Moeckel recalled spotting the discovery while casually running data on his laptop at a dentist’s office, describing the moment he realised the mushball theory must be true.

A Universal Phenomenon Beyond Jupiter

Researchers now believe that Jupiter might not be unique. Gas giants across the universe and even newly forming planets could experience similar mushball processes. “I won’t be surprised if this is happening throughout the universe,” Moeckel told to LiveScience, suggesting that Jupiter’s stormy secrets may echo far beyond our solar system.

Archaeologists Discover 4,400-Year-Old Tomb of Egyptian Prince in Saqqara

Archaeologists Discover 4,400-Year-Old Tomb of Egyptian Prince in Saqqara

Archaeologists have unearthed a stunning 4,400-year-old tomb of an unknown Egyptian prince while digging at the old cemetery of Saqqara (roughly 30 km south of Cairo). The tomb is said to belong to Userefre (or Waser-If-Re) and is now recognised as a son of King Userkaf, Egypt’s Fifth Dynasty founder (c. 2465–2458 B.C.). The tomb’s most impressive element is its colossal pink granite false door—some 4.5 meters (14.8 feet) high and 1.2 meters (3.8 feet) wide—representing a gateway for the soul during and after death. The first of its kind to be discovered at Saqqara, this monumental pink granite false door indicates the prince’s elevated rank, excavation director Zahi Hawass told Live Science in an email. The expensive Aswan granite, generally reserved for the elite class, emphasises the prince’s exalted rank.

Tomb Architecture and Inscriptions

As per a report by LiveScience, Userefre’s tomb entrance was lavishly decorated in pink granite, and hieroglyphs on the false door enumerate his high-ranking titles, such as “Hereditary Prince,” “Governor of Buto and Nekheb,” “Vizier,” and “Royal Scribe.” The report further highlighted that there was no prior historical trace of Prince Userefre before this discovery. His name probably signifies “Re is powerful,” calling on the sun god. A red granite offering table was also found close to the door, evidencing ancient Egyptian mortuary practices of magically accepting food offerings, the report further added.

Within the tomb, scholars discovered artifacts dating to the early Fifth Dynasty. Thirteen stone stools were found, each of which once held a pink granite statue thought to represent Userefre’s wives, though two of the statues lacked heads. A secondary pink granite doorway featuring the cartouche of King Neferirkare, Userkaf’s successor, and a black granite statue, which had been knocked over among the ruins, were discovered.

Later Reuse and Historical Significance

Evidence shows the tomb was later reused during the 26th Dynasty (c. 688–525 B.C.). Archaeologists also uncovered sculptures from King Djoser’s Third Dynasty (c. 2630–2611 B.C.), including a sandstone statue showing Djoser seated with his wife and ten daughters—a rare depiction of royal women. A standing black granite figure from the 26th Dynasty was also discovered, verifying the tomb’s extended reuse.

Work continues on the site, and the prince’s real burial chamber remains to be discovered. Egyptologist Lara Weiss told LiveScience in a statement the discovery’s significance, saying it “adds to the growing evidence that Saqqara remained a prestigious burial site during the Fifth Dynasty” and sheds light on Egypt’s evolution from a centralised monarchy to a more dispersed elite system.

NASA’s Lunar Space Station Module Enters Final Phase Before Artemis Gateway Launch

NASA’s Artemis program has passed a significant milestone in the development of the agency’s “Gateway” in the orbit of the Moon with the delivery of the Habitation and Logistics Outpost (HALO) module to Northrop Grumman’s facility in Gilbert, Arizona. Part of the moon-orbiting Gateway facility, HALO will serve as a habitat and office to astronauts and researchers travelling to and from the lunar surface under NASA’s Artemis moon program. Critical systems for power, data, life support, and temperature control are being attached to the module. Once finished, HALO will permit NASA and associates to conduct long-term missions and experiments in deep space as part of humanity’s lunar return.

NASA’s HALO Module Begins Final Outfitting for Artemis Lunar Gateway

As per the NASA report, the HALO module was shipped from Thales Alenia Space in Turin, Italy, on April 1, and the spacecraft was greeted during an April 24 viewing milestone. The gathering included remarks from NASA’s Lori Glaze, Gateway Program Manager Jon Olansen, and astronaut Randy Bresnik. Attendees such as NASA Administrator Senior Advisor Todd Ericson and local officials viewed the module and engaged in virtual reality tours showcasing its future role in lunar exploration. The event underscored HALO’s strategic importance to NASA’s lunar infrastructure.

At Northrop Grumman, engineers will install the core systems hardware into HALO, including propellant lines, thermal-control radiators, electric wiring, racks for avionics and other electronics, as well as the hardware to support the spacecraft’s life-support systems. Integration would also be designed for docking with Orion spacecraft, lunar landings and other visiting vehicles. This phase marks HALO’s transition from a basic structure to an operational habitat ready for rigorous space conditions.

ESA’s Lunar Link system will be installed on HALO for communication between lunar missions and Earth and will undergo rigorous environmental testing before launch. NASA is assembling the Power and Propulsion Element (PPE), a solar electric propulsion system, to support the Gateway station in lunar orbit. The 12-kilowatt thruster is currently being tested at Glenn Research Centre.
