 Red Dwarf Star Sends Powerful Flares

NASA's Hubble Space Telescope spotted a dwarf star named J02365, shooting out a super flare that is another reminder that alien life would have a hard time living on planets orbiting theses stars. The flare carried 10^32 ergs of ultra-violet energy towards planets hovering around the star. This was much more powerful than any of the suns recorded flares. A team of scientists called HAZMAT is surveying these dwarfs from young, (40 million years old) medium (about 650 million years) and old (several billion years). They are trying to gather more information on these dwarfs to better understand them.
They want to find out more about these stars because they take up the most space in our universe. It is estimated that 75% of the stars in the observable universe are dwarf stars. Many of these most likely have planets in the habitable zone that have a high possibility of containing water. Which we all know is where life most likely started here on earth. Also, they burn for much longer than any other star. Some of them will even burn for trillions of years. Although, we are not sure if they have reliable habitable zones because of their flares which are extremely deadly. This is the amount of radiation before and during a solar flare.

Sadly life on one of these stars would not be fun. The stars are so dim the habitable zones are extremely close to the star. Causing extremely hot day times, and bone-chilling night times. Also, we have found a planet that has close to the mass of Earth in the "habitable zone" for a dwarf star named Proxima Centauri which happens to be the closet star (besides the sun) to Earth. 

This is very interesting. It is showing us that there are planets somewhat close to us that can support life. But, we were able to find out that habitable planets around these dwarf stars such as Proxima Centauri, are most likely not able to harbor life. However, if humanity is able to survive for the next 30-40 million years, than we could see people be able to live on these planets. this is because the red dwarf stars would've calmed down and grown bigger becoming much like our sun.

Force and Motion in Concerts

Force and Motion Blog  By Amadi Clemens INTRODUCTION: Do you listen to Travis Scott? If so, you know of his most recent album AstroWorld has been on tour. One of his recent shows (in Oakland, California) he performed with a roller coaster. Crazy, right? It wasn’t like a full roller coaster that you see Six Flags. It’s like the Ring of Fire at Clementon Park. His ring ties into his theme park theme! PROS AND CONS: There are pros and cons that follow this event. A pro is that it was a fresh idea. I’ve seen amusement parks and rides in music videos but never live in concert. Another pro is that it was eye-catching and entertaining.. The main idea of a concert is that it is entertaining, this is going back to the idea of fresh. A con is that it’s very dangerous. Although thrilling, what if something goes wrong? What if it breaks? What if it stops mid-way in the year and he can’t rap anymore? Mechanical service would have to come and get him and that can ruin the concert. Another con, ...

Chemical complexities that causes Saturn's rings to change planet’s atmosphere

Ayad Alhazmi 10/19/2018 Chemical complexities that causes Saturn's rings to change planet’s atmosphere New discoveries are made today on Saturn's rings by the Cassini space probe. Based on data from the final orbits of NASA's Cassini space probe shows the rings of Saturn. Some of the most amazing celestial objects in the universe are far more chemically complicated than was previously understood by scientist. When the Cassini space probe first gathered the information from 2017 and the signals of Cassini took scientist a long time to retrieve the information. Also knowing the astrophysicists are still studying it is beyond my reach. I will show you a quote by a professor of physics and astronomy Thomas Cravens. "Two things surprised me. One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past. The second thing is the sheer quantity of it -- a lot more than we originally expected. ...

The Earth is a very big Magnet Its North and South Poles are Highly Magnetic

The Earth is a very big Magnet     Its North and South Poles are Highly Magnetic   By: Alzahraa Alrubaiey Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near, but not quite in the same place as the geographic poles.   The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. A compass point north because all magnets have two poles, a north pole...
