Discover what exist in the universe
A star’s mass determines its color and lifetime. Blue giants are massive stars, much more massive than the Sun, but they don’t burn as long as red dwarfs. This shade of blue is slightly different from what you see in the sky every night. The celestial kind is produced by […]
Red giants are stars that have exhausted their core hydrogen and helium and expanded to millions of miles wide. They burn heavier elements in their cores, resulting in a giant star with a swollen atmosphere. In the final stage of its stellar evolution, a red giant is a large, glowing […]
The Solar Neutrino Problem, an In-Depth Look The solar neutrino problem, also known as the Daytime Sky Effect or the Disappearing Sun Paradox, was an experimental discovery made in 1987. Physicists monitoring a nuclear reactor at the Institut Laue–Langevin in Grenoble, France, found that fewer solar neutrinos had arrived than […]
Scientists have been trying to figure out the age of the Earth for centuries. The process is not as simple as it might seem, and there is no exact answer. There are a few different methods that scientists use to estimate the age of the Earth. Much history has been […]
Neutrinos are elementary subatomic particles with no charge and little or no mass. They participate in only the weak subatomic force and pass through almost unaffected ordinary matter. Neutrinos have no rest mass and travel at speeds close to the speed of light. Neutrinos oscillate between different flavors (electron, muon, […]
The exoplanet discovery race is on. Since 1995, when the first exoplanets were found orbiting a pulsar (a fast-spinning neutron star), astronomers have discovered more than 2,000 planets around other stars. The most striking thing about this large sample of alien worlds is their diversity: these planets are unlike anything […]
Global warming is the observed long-run, up to century, rise in the average temperature of Earth’s climate system and its related effects. Collective of scientific evidences show that the climate system is warming. With global warming and climate change becoming a real issue, it’s important to know how to help […]
Our planet has seen a rise in global temperatures in the last century. Not only is this impacting the weather patterns that we experience, but it is affecting how quickly ice caps melt and how much rainfall gets delivered to certain geographical areas. Climate change effects are being observed in […]
There are many theories regarding why there is lava on the Earth. Scientists believe it is formed from melted rock deep inside the Earth and then rises to the surface. One theory says that magma (molten rock) rises to the top of a volcano when gasses dissolved in it expand […]
The Sun is a huge gas, or plasma, that produces heat and light by nuclear fusion. The Sun’s energy also fuels the Earth’s weather and climate through solar radiation. The Earth’s average surface temperature is about 15 degrees Celsius (59 F or 288 K). As the planet goes in and […]
