This year saw numerous groundbreaking discoveries that rewrote our understanding of the universe, animals, and human history. Here are five of the most significant science stories from 2024.
The Universe’s Expansion Speed Conundrum
A recent study by the James Webb and Hubble space telescopes confirmed a phenomenon where the universe’s expansion speed varies depending on location. This discovery challenges our understanding of the cosmos, with lead researcher Adam Riess stating that the measurements confirm “what remains is the real and exciting possibility we have misunderstood the universe.”
Spiders on Mars
In April, the European Space Agency (ESA) captured images of strange spider-like markings on Mars’ south polar region. Initially thought to be extraterrestrial life, these structures were later revealed to be a seasonal geological feature born from melting carbon dioxide ice.
Ancient Sea Monster Discovery
A 200-million-year-old fossil, named Icthyotitan severnensis, was discovered in Somerset, UK. Estimated to be around 82 feet long, this discovery smashes the previous record for the largest marine reptile. The researchers believe that the living animal would have been a Triassic predator.
Earth’s Inner Core Slowing Down
Scientists have observed a trend where Earth’s inner core is spinning unusually slowly since 2014. Researchers speculate that this could potentially lengthen days on Earth, although only by a few milliseconds.
Ancient Child Sacrifice Burial Mound
In November, archaeologists uncovered a 700-year-old burial mound in Peru containing the remains of sacrificed children and adults. The discovery sheds light on an ancient practice where children’s hearts were removed to “energize” agricultural fields.
These science stories showcase the incredible advancements being made in our understanding of the universe, animals, and human history. From the mysteries of the cosmos to the secrets of ancient civilizations, 2024 was a year marked by groundbreaking discoveries that continue to rewrite our knowledge of the world.
