A study published in April 2025 provides new insight into one of the mysterious historical climate change periods known as LALIA (the Late Antique Ice Age). This period is known to last from 536 to 660 AD. The trio of scientists, namely, Christopher Spencer, Ross Mitchell and Thomas Gernon, published in a journal describing the analysis of misplaced Greenland rocks found lodged in the cliffs of Iceland, offering direct evidence of iceberg activity connected to this period of an ice age.

Discovery of the LALIA

The study was published in the journal Geology. As per Phys.org, the earlier research has depicted that the Earth’s northern hemisphere had undergone a chilly spell beginning around 540 AD because of the eruption of huge volcanoes, which led to the rise in debris in the atmosphere, leading to the darkening of the skies. A few historians speculated that the sudden cold weather led the Goths to attack the Romans in Europe, as they moved toward the south, warmer regions led to the fall of the Roman Empire.

Understanding the Misplaced Rocks

The researchers studied some cliffs on the western coast when they noticed that the rocks actually looked out of place. They collected a few rocks to study in the lab. The team crushed the rocks in the lab to study their remnants under a microscope. They pulled the zircon crystals from the centre of these rocks.

In their lab, the team crushed the rocks and looked at their remnants under a microscope, allowing them to pull out zircon crystals from their centres. These crystals can be used as a time capsule. After studying their age and composition, the scientists could trace the original place of these rocks across Greenland. This predicts that these rocks were moved by someone more than 1500 years ago.

The scientists studied the rocks’ age placed at the LALIA, depicting that the rocks were moved after breaking the ice from the large glaciers of Greenland that formed as per the colder scenarios formed during that period.

Scope of the Study

The research stands as a major step forward in understanding the Earth’s climate in the past. These rocks have given clear proof of increased glacial activity at the time of LALIA, indicating the outcomes of modern and future climatic changes.

SpaceX Fires Up Starship Upper Stage for Ninth Test Flight in Static Fire Trial

SpaceX Fires Up Starship Upper Stage for Ninth Test Flight in Static Fire Trial

SpaceX’s next-generation Starship spacecraft has fired up in another test as the company prepares for its ninth flight. Starship conducted a full-duration static fire of its upper stage at the Starbase facility in South Texas on May 12th. The 171-foot-tall (52-metre) vehicle fired all six of its mighty Raptor engines for the full-duration burn, which took about 60 seconds. This marked the third such static fire for this specific ship, which is now undergoing final checks. SpaceX shared video and images of the trial in a post on X the following day.

Starship Nears Ninth Launch as SpaceX Advances Toward Mars-Ready Reusability

As per a Space.com report, the static fire is one of the last key milestones before the vehicle’s upcoming launch, though no date has yet been announced. The booster assigned to Flight 9 has already conducted a static fire test, sparking talk it may only be weeks from flight. Fully stacked, Starship stands 403.5 feet, making it the most powerful rocket system ever assembled. Its super-heavy booster and ship upper stage are intended for full reuse, a requirement for voyages to the moon, Mars, and beyond.

Starship has completed eight test flights to date, two of them in 2025. Though the missions themselves blasted off without a hitch, the ship’s upper stage flubbed both times shortly after arriving in space. During those flights, Super Heavy managed to fly back to Starbase and land with the aid of its giant launch tower’s “chopstick” arms in a dramatic manoeuvre that was one of a kind for SpaceX’s rocket-catching system. But both times the ship exploded less than 10 minutes after launch, a failure that has raised concerns about the stability of that upper stage.

SpaceX Starship, the Mars colonisation spacecraft, has now completed more than one full static fire test run, and it is expected to be a fully reusable spacecraft after the next test flight. Until then, space watchers will have to keep waiting for progress at Starbase. The ninth launch of this giant vehicle is probably not too far off if SpaceX continues to evolve and test at the pace they are going.

Hikers Stumble Upon 600 Gold Coins in Czech Forest Near Polish Border

Hikers Stumble Upon 600 Gold Coins in Czech Forest Near Polish Border

Two hikers accidentally discovered a treasure trove in Czech Republic . While taking a stroll in the forests surrounding Zvičina Hill in the Krkonoše Mountains near Poland’s border, they spotted an aluminium can and an iron box protruding slightly above the surface in a stone mound. The containers contained about 600 gold coins and a stunning assortment of gold artifacts. Discovery of this treasure worth more than $340,000 has drawn attention of researchers, arising questions about both the origin of the coins and how did they end up in such a remote location.

Tracing the origin of coins

According to the report by Vojtěch Brádle, a numismatist from the Museum of Eastern Bohemia, the majority of the coins were minted between 1808 and 1915. They originate from the Austria-Hungarian Empire, particularly under the reign of Emperor Franz Joseph I. Some of the coins feature countermarks minted in the Kingdom of Serbs, Croats, and Slovenians after the collapse of the Austro-Hungarian Empire.

The 598 coins cover a broad historical period, containing currency from France, Belgium, the Ottoman Empire, and Russia too. The range of provenances makes it difficult to track how the coins got to where they were, or just why they were stashed away at all. “It is hard to say whether it was Czech, German, or Jewish gold,” said Petr Grulich, director of the Museum of Eastern Bohemia, according to Dailymail.

Theories about the hiding place

There are several theories and speculation about how these coins and artifacts were hidden in such a remote location. One theory suggests that the items were concealed during Nazi Germany’s occupation of Czechoslovakia.

Following the Munich Agreement of 1938, large numbers of Jews and Czechs fled their homes in the annexed Sudetenland to escape persecution. Some historians believe that the treasure was buried during this time in an effort to protect it from the invading Nazi forces.

NASA’s IMAP Spacecraft Prepares to Map the Solar System’s Edge

On may 10th, a semitrailer delivered NASA’s Interstellar Mapping and Acceleration Probe or IMAP to the Astrotech space operations facility all the way from NASA’s Marshall Space Flight Center in Huntsville, Alabama. The IMAP mission is a modern-day celestial cartographer that will map the solar system by studying the heliosphere, a giant bubble created by the Sun’s solar wind that surrounds our solar system and protects it from harmful interstellar radiation. Tentatively scheduled for launch no earlier than fall 2025 on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy, IMAP will be processed fuelled and encapsulated by the technicians in Astrotech facility.

About the mission

According to reported  NASA’s blog, The IMAP mission will orbit the Sun at a location called Lagrange Point 1 (L1), which is about one million miles from Earth towards the Sun. From this location, IMAP can measure the local solar wind and scan the distant heliosphere without background from planets and their magnetic fields. The spacecraft will use 10 scientific instruments to study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system.

At NASA’s Marshall Space Flight Center, IMAP went through thermal vacuum testing at the X-ray and Cryogenic facility that simulates harsh conditions and dramatic temperature changes to simulate the environment during launch, on the journey toward the Sun.

Mission Management

IMAP is the fifth mission in NASA’s Solar Terrestrial Probes program portfolio. It is lead by Princeton University professor David J. McComas with an international team of 25 partner institutions. The spacecraft was built and operated from The Johns Hopkins Applied Physics Laboratory.

Information from this mission are expected to provide early warnings about space weather, which can affect human space explorers and technological systems like satellites and power grids that can affect life on Earth.
