Martian impact basins, previously assumed to be demagnetised due to an inactive planetary dynamo, may instead reflect the impact of a reversing magnetic field, a new study suggests. Led by Dr Silpaja Chandrasekar, PhD, indicates that Mars’s fluctuating dynamo may have been active longer than anticipated, with implications for understanding planetary evolution. Impact Basins and

SpaceX is set to carry out a first-of-its-kind manoeuvre on November 8, with its Dragon cargo capsule performing a “reboost” of the International Space Station (ISS). The 12.5-minute engine burn will lift the ISS to a higher altitude, addressing the gradual orbital decay caused by Earth’s atmospheric drag. This task has traditionally been managed by

In 2013, a team led by Ning Zeng, a climate scientist from the University of Maryland, unearthed a remarkable find while conducting an experiment in Quebec, Canada. The researchers were digging a trench to test if burying wood under clay soil could prevent its decomposition and keep carbon locked away from the atmosphere. During this

Astronomers are watching two unusual black holes, each presenting phenomena that challenge current understanding of these cosmic giants. One, a “serial killer” black hole, is about to devour its second star within five years, while the other, part of the newly discovered triple system V404 Cygni, has disrupted long-held theories of black hole formation. The

NASA’s Parker Solar Probe will make a close approach to Venus on Wednesday, marking the spacecraft’s seventh and final flyby of the planet. This manoeuvre will set the probe on a course for its historic plunge toward the sun, bringing it within 3.8 million miles of our star’s surface — closer than any human-made object

A seismic wave detected shortly before the Hunga Tonga-Hunga Ha’apai eruption in January 2022 could help scientists predict future volcanic activity in remote ocean areas. A study published by the American Geophysical Union suggests that the seismic wave, detected 750 kilometres from the volcano, was likely triggered by a rupture in the oceanic crust. This

India has delayed its inaugural astronaut mission under the Gaganyaan programme to 2026, pushing the timeline a year beyond the original schedule. The decision, announced by S. Somanath, Chairman of the Indian Space Research Organisation (ISRO), reflects a commitment to safety in light of recent aerospace industry setbacks. According to Somanath, India’s first manned mission

On January 15, 2022, the Hunga volcano near Tonga erupted in an explosive event that sent shockwaves across the planet. The eruption happened around the same time as Cyclone Cody. It created a shockwave powerful enough to trigger low, booming sounds that were heard from New Zealand to Alaska. It also caused a tsunami that

The Hang Son Doong cave in Vietnam, located in Quang Binh Province within Phong Nha-Ke Bang National Park currently holds the title as the largest known cave in the world. With dimensions exceeding three miles (5 km) in length and 660 feet (200 m) in height, this natural wonder could house 15 Great Pyramids of

In 2015, U.S. Navy pilots conducting training flights along the East Coast reported encounters with unusual, high-speed objects moving over the water. Descriptions from the pilots reveal that these oval-shaped objects appeared to rotate as they moved, covering vast distances at incredible speeds. Multiple pilots confirmed sighting these objects, which they noted were different from

NASA’s Perseverance rover which is positioned in the Jezero Crater on Mars, recently observed a remarkable celestial event as the moon Phobos drifted across the Sun. Captured on September 30, this moment offered a rare glimpse into Mars’ sky, where the unique “googly eye” effect of the eclipse unfolded for the rover’s Mastcam-Z camera. The

South Korea’s space agency announced plans on Friday to launch a solar coronagraph to the International Space Station (ISS) in a collaborative mission with NASA. Developed as part of the Coronal Diagnostic Experiment (CODEX), this instrument is set to observe and gather data on the Sun’s corona and the solar wind as well as the

An unprecedented nine-day tsunami following a significant rockslide in Greenland’s Dickson Fjord was recently recorded by the international Surface Water and Ocean Topography (SWOT) satellite, a collaborative mission by NASA and France’s Centre National d’Études Spatiales (CNES). The event, which took place in September 2023, saw a unique pattern of seismic waves resonate around the

ESA’s Proba-3 mission, designed to create solar eclipses in space to study the Sun’s corona, has officially left European soil and is en route to its launch site in India. This dual-spacecraft mission departed from Redwire Space’s facility in Kruibeke, Belgium, to travel to the Satish Dhawan Space Centre near Chennai, where the final launch

Earth recently captured a small asteroid known as 2024 PT5, temporarily transforming it into a second moon. This rare event was confirmed by astronomers from Massachusetts Institute of Technology (MIT) and the Complutense University of Madrid, offering a glimpse into these elusive “mini-moons” that Earth occasionally holds within its orbit. However, Earth’s newly acquired companion is

A study has revealed that controlling sugar intake in infancy can significantly reduce the risk of chronic illnesses, such as diabetes and high blood pressure, later in life. Researchers analysing historical data from World War II’s sugar rationing in the United Kingdom found that limited sugar consumption in childhood led to healthier adult outcomes, emphasising
