NASA scientists issue ‘urgent’ warning: Social jet lag is the dangerous sleep habit you are ignoring When we hear the term “jet lag,” most of us instantly picture the disorientation and exhaustion after crossing multiple time zones on a long-haul flight. But what if jet lag could happen without ever boarding a plane? Recent research,…
Elon Musk’s Starlink satellite venture is said to launch operations into the Indian market. Starlink is funded by SpaceX and promises high-speed internet using a constellation of low-Earth orbit (LEO) satellites. Since India has such a huge geography to cover and numerous underserved zones, Starlink’s technology has the potential to usher in a revolutionary change…
A dense cluster of defunct satellites and fragmented metal orbits Earth. (AI-generated image) BENGALURU: Globally, 2024 continued to see a significant number of space launches, with 261 attempts and 254 successes, resulting in 2,578 operational satellites and a total of 2,963 objects placed in orbit, although the total objects placed in orbit is slightly lower…
A recent NASA-led study, highlighted by New Scientist, reveals that this accelerated re-entry is caused by increased solar activity during the solar maximum—a period of intense solar storms and radiation. These storms heat and expand Earth’s upper atmosphere, increasing atmospheric drag on satellites and hastening their descent. This shift poses new challenges for satellite operators,…
A recent study from the Max Planck Institute for Biology of Ageing in Germany has revealed that a combination of two existing drugs—rapamycin and trametinib—can extend the lifespan of mice by up to 30 percent. Not only did the mice live significantly longer, but they also remained healthier in old age, showing reduced inflammation, delayed…
Sunita Williams and Butch Wilmore after spending over nine months aboard the International Space Station (ISS) due to Boeing Starliner capsule issues, have safely returned to Earth. Originally scheduled for an eight-day mission, their stay extended significantly, culminating in a March return. Since then, both astronauts have been undergoing intensive physical rehabilitation to readjust to…
A new study has revealed that the land in South Africa is rising, and the reason may be more alarming than previously thought. Between 2012 and 2020, researchers recorded an average uplift of 6 millimetres, or nearly 2 millimetres each year. While it was earlier believed that geological activity or mantle flow was causing this…
Galaxy cluster Abell S1063 (Nasa) As part of the ‘picture of the month’ series, Nasa has revealed a new image taken by the James Webb telescope that gives a look into the distant past. This picture of the galaxy cluster Abell S1063 is a gigantic collection of galaxies lying 4.5 billion light years from Earth…
In May, the Hubble telescope released a picture of a different galaxy, known as HerS 020941.1+001557, as it appeared 11 billion years ago. Along with SDSS J020941.27+001558.4 and SDSS J020941.27+001558.4, it forms a partial ring captured through gravitational lens, also known as the Einstein Ring. Source link
