Researchers from IIT Guwahati and the Indian Space Research Organisation (ISRO) have made a surprising discovery that could reshape our understanding of X-ray pulsars. They found that the X-rays emitted by Swift J0243.6+6124, the first known Galactic Ultraluminous X-ray Pulsar, exhibit an unexpectedly low level of polarization. This pulsar, which is located within our galaxy,

In 2023, scientists discovered subtle ripples in the fabric of spacetime, known as gravitational waves, originating from pulsar timing arrays. These low-frequency waves were initially thought to be the result of a phase transition that occurred shortly after the Big Bang. However, new research has cast doubt on this explanation, suggesting that our understanding of

Astronomers have achieved a significant breakthrough with new high-resolution images of Polaris, also known as the North Star. Using the CHARA Array located on Mount Wilson in California, researchers have captured unprecedented details of the star’s surface. This is the first time scientists have been able to observe features such as large bright and dark

NASA is grappling with a significant challenge as two US astronauts, Sunita Williams and Barry Wilmore, find themselves stranded aboard the International Space Station (ISS). Initially scheduled for an eight-day mission, their return has now been delayed to February due to technical problems with Boeing’s Starliner spacecraft, which was supposed to bring them back to

Physicists have recently observed an unexpected phenomenon in a superconducting material, potentially pushing the boundaries of what’s possible in this field. The discovery centres on a material typically known as an electrical insulator. In this insulator, researchers found that electrons could pair up at temperatures as high as minus 123 degrees Celsius (minus 190 degrees

Astronomers have traditionally relied on helioseismology to estimate the Sun’s age by analysing the vibrations that ripple through its interior. However, recent research has uncovered a significant obstacle, the Sun’s magnetic activity, which follows an 11-year cycle, appears to be distorting these measurements. Data from the Birmingham Solar Oscillations Network (BISON) and NASA’s SOHO mission,

New research suggests that peculiar zones in the Earth’s mantle, where seismic waves slow dramatically, may be more common than previously thought. These ultra-low velocity zones (ULVZs) have intrigued scientists for years due to their ability to slow seismic waves by up to 50 percent. Recent findings indicate that these enigmatic features could be present

Indian Space and Research Organisation (ISRO) has released a fresh set of images from the Chandrayaan-3 mission, coinciding with the first anniversary of its successful landing on the Moon. These images, taken by the Vikram lander and Pragyan rover, showcase key moments from the mission, including Pragyan’s attempts to imprint India’s national emblem on the

India is celebrating its inaugural National Space Day today, marking a significant milestone in the country’s space exploration journey. This day commemorates the historic event of August 23, 2023, when Chandrayaan-3 successfully made a soft landing on the Moon. With this achievement, India became the fourth nation to land on the Moon and the first

MIT engineers have achieved a major breakthrough with the creation of a zinc-air microbattery, a device so tiny it measures just 0.1 millimetres in length and 0.002 millimetres in thickness—about the thickness of a human hair. This innovative battery harnesses oxygen from the air to oxidise zinc, generating up to 1 volt of power. This

The Indian Space and Research Organisation (ISRO) Chief S. Somanath has stated that the ongoing challenges faced by NASA astronaut Sunita Williams, who has been stuck in space for over 60 days, will provide valuable lessons for India’s Gaganyaan mission, as per a report. Williams and fellow astronaut Butch Wilmore have encountered difficulties with Boeing’s
