New research from the Hubble Space Telescope and NASA‘s Mars Atmosphere and Volatile Evolution (MAVEN) mission reveals that Mars sheds water more quickly when it is closest to the Sun. These seasonal changes are tied to the planet’s orbit, where the increased solar heating during perihelion accelerates the escape of hydrogen atoms from Mars’ atmosphere.

New research suggests that a powerful El Niño cycle, fuelled by a massive release of carbon dioxide, may have contributed to Earth’s largest mass extinction around 250 million years ago, during the end of the Permian period. Volcanic eruptions in what is now Siberia caused enormous amounts of carbon dioxide to enter the atmosphere, resulting

In a groundbreaking discovery, researchers have identified a previously unknown Neanderthal lineage based on DNA from a fossil found in the Grotte Mandrin rock shelter in France. This lineage, belonging to an individual referred to as “Thorin,” reportedly evolved in isolation from other Neanderthal populations for nearly 50,000 years. The finding has offered a fresh

Voyager 1, the farthest human-made object from Earth, has recently undergone a critical adjustment to its thruster system as it navigates the vast expanse of interstellar space. Despite being operational for 47 years, the spacecraft required a clever fix to maintain its alignment and continue sending valuable data back to Earth. Voyager 1’s Thruster Issue

Polaris Dawn, a private space mission has set a new record for the highest orbit reached by humans since NASA‘s Apollo programme. On 10th September 2024, the four-member Polaris Dawn crew aboard SpaceX‘s Dragon spacecraft Resilience achieved an apogee of 1,400.7 kilometres. This surpasses the 1966 Gemini 11 mission’s altitude of 1,373 kilometres, marking the

Antarctica, now a vast frozen continent, was not always covered in ice. Around 34 million years ago, during the Eocene-Oligocene boundary, the continent was ice-free. According to Eric Wolff, a paleoclimatologist from the University of Cambridge, Antarctica resembled northern Canada with tundra and coniferous forests before it froze. The shift to ice began due to

A significant discovery of ancient silver coins has been made on the Mediterranean island of Pantelleria, located between Sicily and Tunisia. Archaeologists from the University of Tübingen, Germany, unearthed 27 Roman silver coins, known as “denarii,” dating back more than 2,000 years. The coins were found hidden in a hole in the wall during excavations

In 2006, a fungal disease called white-nose syndrome began decimating bat populations across New England. Over the following decade, the loss of these bats, essential for controlling insect populations, led to significant consequences for agriculture and human health, according to a new study. With fewer bats around to consume insects, farmers resorted to increased use

Glaciers have long served as nature’s deep freezers, preserving the physical characteristics of past climates and the genetic blueprints of ancient life forms, including viruses. As the planet’s climate continues to shift, scientists are increasingly looking to these frozen archives to understand how pathogens have historically responded to environmental changes. By studying viral genomes extracted
