Exoplanets 101: Does the earth have a twin?

Posted on April 7, 2019 by alfredprah

Potential Habitable Planets An extrasolar planet is a planet that orbits a star that’s not our sun. Even though these planets can be recognized, and their sizes measured, they are light years away so it would take astronomers thousands of years to reach these extrasolar planets. To detect these planets, scientists use either one of … Continue reading Exoplanets 101: Does the earth have a twin? → Continue reading →

The Energy within the Sun

Posted on March 13, 2019 by kierannaughton5896

The sun is a main sequence star, which means it is powered through the process of nuclear fusion. Nuclear fusion is the process of multiple (two or more) nuclei combining to form a completely different nuclei. This process occurs under extreme conditions and releases immense amounts of energy. The sun, at its core (literally), is … Continue reading The Energy within the Sun → Continue reading →

The Sun – the heart of our solar system

Posted on March 12, 2019 by alfredprah

Planetary System The star at the center of the solar system plays a special role for us here on earth. It was formed about 4.5 billion years ago, in the Orion spur (in the milky way galaxy). It was born from the collapse of a cloud and dust called the “solar nebula”. It then condensed … Continue reading The Sun – the heart of our solar system → Continue reading →

Radioactivity 101. Is the sun radioactive?

Posted on March 12, 2019 by alfredprah

sun spots and solar flares Chemical reactions occur because atoms strive for stability. Just like the outer electrons require a certain number of electrons to become stable, the nucleus requires a certain number of protons and neutrons to achieve this stability. The decomposition (breaking down) of the nucleus to achieve this stability is what we … Continue reading Radioactivity 101. Is the sun radioactive? → Continue reading →

Second Planet to the Sun

Posted on March 12, 2019 by reallyroyalqueen

The planet Venus is named for the Roman goddess of love and beauty. It is the second largest terrestrial planet. It is also the second brightest natural object in the sky. Venus’ apparent magnitude of -3.8 to -4.6 makes it visible on a clear day. Venus’ atmosphere can be divided into two layers: the cloud … Continue reading Second Planet to the Sun → Continue reading →

Nuclear Fusion

Posted on March 12, 2019 by bobbyc

  Nuclear fusion is where two nuclei combine resulting in a displacement of energy. The fusion of hydrogen atoms into helium specifically is what powers the energy output of the sun. This can only occur under the most extreme conditions – typically, the positively charged nuclei of two atoms repel each other quite strongly, and … Continue reading Nuclear Fusion Continue reading →

Space Weather

Posted on March 12, 2019 by alexdickey18

In this post, we will be discussing space weather! Space weather is dissimilar from the weather that we experience on earth, however it is still fascinating to understand. Space weather, in our solar system, is sparked by activity on the suns surface. Spewing gases and solar flares on the surface of the sun form into … Continue reading Space Weather → Continue reading →

The Sun

Posted on March 12, 2019 by calebglotta

Everyone knows the sun is what gives us light, much of our heat, and is vital to life on Earth, however there are many intriguing aspects that people do not know. The sun was formed four and a half billion years ago from the gas of a collapsing space cloud. This cloud continued to contract … Continue reading The Sun → Continue reading →

Understanding Our Sun

Posted on March 12, 2019 by dayvon

On August 12, 2018 the Parker Solar Probe was launched. The mission of this probe is to investigate activity in the Sun’s corona in order to provide us with information that can help us understand more about the star and Earth’s connection to it. Analyzing the data being sent back will allow scientists to potentially … Continue reading Understanding Our Sun → Continue reading →

Nuclear Fusion

Posted on March 12, 2019 by anna_h

The Sun generates energy by fusing hydrogen into helium due to a process known as nuclear fusion. Fusion occurs within the Sun because the plasma in the solar core is full of hot gases that collide with one another at extremely high speeds. In most cases, electromagnetic repulsion forces deflect the nuclei of the two … Continue reading Nuclear Fusion Continue reading →
