Was Earth a "Green Marble"?
When we envision Earth from space, we frequently picture the famous "Blue Marble"—a world covered primarily by the deep blue of its oceans, swirling with clouds, and lush with verdant areas. However, Earth might have had a quite different appearance long before it developed into the water-rich planet it is today. According to some scientists, Earth was originally a "Green Marble," a planet without the deep blue glimmer we associate with modern Earth, with green oceans and a thick, hazy atmosphere. A fascinating chapter of Earth's history is presented by this prehistoric incarnation of our planet, one that provides insights into early life, the environment, and even the evolution of other potentially livable worlds.

SpaceX Starlink Launch 2025: 21 New Satellites Deployed to Boost Global Internet Coverage
SpaceX Starlink Launch 2025: 21 New Satellites Deployed to Boost Global Internet Coverage In a significant stride toward global internet coverage SpaceX successfully launched 21 Starlink satellites into low Earth orbit (LEO) on March 12 2025. The mission conducted from Cape Canaveral Space Force Station in Florida marked yet another milestone in the company’s ambitious plan to build a vast satellite internet network. The launch designated Starlink Group 12-21 took place at 10:35 p.m. EDT aboard a Falcon 9 rocket. As has become routine for SpaceX the first stage of the Falcon 9 was successfully recovered landing on the droneship A Shortfall of Gravitas stationed in the Atlantic Ocean. This was the 22nd flight for this particular booster showcasing SpaceX’s commitment to reusability and cost-effective space travel. The 21 satellites included 13 equipped with direct to cell capabilities a groundbreaking technology that allows the satellites to communicate directly with standard mobile devices. This advancement could eliminate the need for traditional cell towers in remote areas bringing reliable mobile coverage to places previously considered unreachable. Starlink is SpaceX’s satellite internet constellation project designed to provide high speed low latency broadband internet to underserved and remote regions around the world. Since its initial launches in 2019 the program has seen rapid growth. With this latest deployment SpaceX has now launched more than 8,100 Starlink satellites of which over 7,000 are currently operational. A theses satellites orbit the Earth at altitudes ranging from 340 km to 1,200 km significantly lower than traditional communication satellites. This lower altitude reduces latency and allows for faster data transmission key benefits for internet users particularly those in rural areas with limited infrastructure.

Walking on Fire
For thousands of years, firewalking has captivated the human imagination. From ancient tribal rituals to modern-day spectacles, the sight of a person walking barefoot across a bed of glowing red-hot coals continues to stir awe, disbelief, and sometimes fear. But according to one award-winning American physicist, there’s no magic involved—just physics.

Beyond the Stars: How JWST Is Redefining Cosmic Discovery
Floating more than a million miles from Earth, quietly orbiting the Sun at a gravitationally stable point called L2, the James Webb Space Telescope (JWST) is on a mission to uncover the deepest cosmic secrets. Since its deployment in 2021 and first images in 2022, JWST has not only met the world's sky-high expectations—it’s shattered them.
