Most of the time, people never question the colour of water. It feels invisible in a glass, like air you can drink. Then a holiday comes around, someone stands by the sea, and suddenly the water looks blue or green or something in between. It’s the same substance, yet it behaves differently depending on how…

The Red Sea is a narrow stretch of water that runs southeast from Suez in Egypt for about 1,200 miles (1,930 km) all the way to the Bab el-Mandeb Strait, which links it to the Gulf of Aden and then the Arabian Sea. It separates the coasts of Egypt, Sudan, and Eritrea on the west…

Space looks dark and cold from Earth, but sunlight beyond our atmosphere is harsh in ways most of us never experience. Without air, clouds, or an ozone layer to soften it, solar radiation hits with full force. That raises a simple, almost playful question that hides a serious concern: do astronauts need sunscreen in space?…

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more subtle manner. Instead of moving people or objects through history, researchers are investigating whether it is possible to reverse physical processes themselves. Recent advances in wave physics hint that, under the right conditions, time can…

The spirit of Christmas is here, gifts and wishes are pouring in, and the joy of the holidays has taken over. Amid the choirs and carols of the holiday, Nasa shared its celestial greetings, celebrating the day.The cosmic tree from the nebula group NGC 2264, formed with a cluster of stars emitting blue and white…

Deep down, beneath the icy edges of the Greenland Sea, a remarkable and previously undiscovered geological and biological complex has been found by scientists. The existence of this topographic anomaly deep down in the sea, where light, high pressure, and low temperature are prevalent factors, extends our understanding of what is known about the oceanography…

Russia aims to build a nuclear power plant on the moon by 2036 to power its lunar program and a joint Russian-Chinese research station. Major powers are competing to explore the moon, with both Russia and the United States racing to establish lunar bases for future space missions.The Russian space agency, Roscosmos, has signed a…

It does not look like a breakthrough at first. Just the faint outline of a foot, pressed into what was once soft ground and later hardened by time. No bones nearby. No tools neatly arranged. And yet this single footprint, found in southern Chile, may be one of the most important human traces ever uncovered…

Cracking knuckles creates a gas cavity in fluid; it makes noise but causes no damage Nearly everyone who cracks their knuckles has heard the same warning at some point: keep doing that and your hands will grow, your joints will suffer, and arthritis will follow. The habit has long carried a reputation for causing damage,…

As NASA plans for long-term human missions beyond Earth, one question keeps resurfacing: how do you sustain life in places where resupply from Earth is slow, expensive, and limited? Machines and technology will play a significant role, but scientists are increasingly turning to biology for answers. In recent research, insects have emerged as unlikely but…
