Scientist finds elusive star with origins close to Big Bang

Astronomers have found what could be one of the universe’s oldest stars, a body almost entirely made of materials spewed from the Big Bang. The discovery of this approximately 13.5 billion-year-old tiny star means more stars with very low mass and very low metal content are likely out there—perhaps even some of the universe’s very first stars. The star is unusual because ...

Magnetic waves create chaos in star-forming clouds

“New research by Stella Offner, assistant professor of astronomy at The University of Texas at Austin, finds that magnetic waves are an important factor driving the process of star formation within the enormous clouds that birth stars. Her research sheds light on the processes that are responsible for setting the properties of stars, which in turn affects the formation of ...

Why the water remains cool in earthen pitchers?

The water in pitchers gets evaporated through the pores present in the pitcher body causing the by evaporation. Some heat energy is utilized during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water present.

Global Climate is affected by sea ice: Why ?

On poles Ocean is covered by Sea ice and it’s  frozen water that is formed and melts in the ocean. It can be differentiated from the presence of icebergs and glaciers on land. Sea ice expands during winter season and gets melt down during summers, there are certain regions in oceans part of  sea ice remains round the year. Approximately Fifteen percent (15%) of the oceans ...

Planet are made of Off What?

Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water. In our solar system, the four “gas giants” ...

Sound Cannot Travel through Vacum, Why ?

The reason is sound travels in the form of Waves and waves needs a medium to travel, and in vacuum there is no medium to travel through. A vacuumis an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.

What is King Tide?

its not a scientific phenomena, It is used to denote the immense high Tide level. These are long-period waves that are produced and roll around the planet due to the ocean is “pulled” back and forth as moon and sun produces the gravitational pull, these bodies interact with the Earth in their monthly and yearly orbits. Higher than normal tides typically occur during ...

How far does light travel in the ocean?

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or “sunlight,” zone. This ...
