__ DO BLACK HOLES HELP STARS FORM? __ [] //** What effect do you think black holes have on stars and are they always negative or positive? Black Holes had being thought to hinder the birth of stars, but now an international team of astronomers studying studying the nearby galaxy Centaurus A have found quite the opposite: a black hole that seems to be helping stars form. **// **//The densest central parts of the cloud are compressed and collapsed to form stars, while the gas on the outskirts is swept away from the tip of the filament, like a pile of autumn leaves in the wind. Black holes at the centre of galaxies 'switch on' from time to time, driving material around them into outflows that can stretch for millions of light years.//** **//The astronomers used the Hubble Space Telescope's Wide Field Camera 3 (WFC3) to study the central regions of Centaurus A, catalogued as NGC 5128, a bright galaxy 13 million light years away in the direction of the southern constellation of Centaurus. In visible light, a prominent belt of dust can be seen running across the galaxy and when observed at X-ray and radio wavelengths it has jets extending for up to a million light years from a central black hole. With WFC3, the scientists took a close look at the 'inner filament', a region located close to the outflow that is a source of ultraviolet and X-ray emission, as well as being bright in visible light. Using the Hubble images, the teams were then able to map out//****//the star formation history of the filament with unprecedented accuracy. The team discovered that the tip of the filament closest to the outflow contains young stars, the ages of which are similar to the time since the black hole’s outflow “switched on”.//** **//We are used to thinking of black holes as cosmic cannibals with the supermassive variety swallowing up gas, dust and stars. But new research with the Hubble Space Telescope suggests that these monsters lurking at the hearts of galaxies may also help create new stars.//**//**With the studying of Centaurus the astronomer found that**// **//the filament closest to the outflow contains young stars, the ages of which are similar to the time since the outflow 'switched on' but that there are no young stars further up the filament. This is exactly what is expected from an outflow overrunning a cloud of gas sitting in its path. The densest central parts of the cloud are compressed and collapse to form stars, while the gas on the outskirts is swept away from the tip of the filament. The astronomers concluded that black holes contribute to the formation of stars.//** **//By: Godwin Djokoto//**

====Scientists studied a giant cloud about 770 light years away from Earth that led to new observations about star formation. The new observations show an important step, specifically the second step, in start formation.==== Stars are formed, astronomers think, when such a cloud of gas and dust collapses gravitationally, first into clumps, then into dense cores, each of which can then begin to further collapse and form a young star.

Scientist say life is possible within our solar sysytem rather than on Earth. The scientist explore the data collected from sensors onboard the spacecraft Cassini Plasma Spectrometer and analyze it along with data collected from other moons around Saturn and Jupiter to prove this. They also describe the process on how the oxygen is created in icy celestial bodies. They then describe a process of how living organisms could generate on the Dione. Given the information presented, do scientist believe life will be discovered on one of these bodies?

 * First Atomic Hydrogen Spectral Line Images of a Nearby Galaxy**

The article I choice was about astronomy and it’s titled //“First Atomic Hydrogen Spectral Line Images of a Nearby Galaxy”// with the information and research provided by the South African Square Kilometre Array. The article contains a lot of different quotes from different college professors and college students. They all are talking about how astronomers have now found a way to see how a nearby galaxy called NGC 3109 move. NGC 3109 is a small spiral galaxy located in the constellation of Hydra. From these observations we see the HI radio emission of this galaxy and how it’s moving.

 * The conditions in space:**

The article i chose was about the conditions astronuts go through while they are in space. Most astronauts can expect a steady stream of solar winds causing geomagnetic storms with heavy ultraviolet radiation. Talk about intense ! I chose this article because i have always been curoious on the conditions that astronauts have to live through while they are in space. []

 * "Super Earth":**

The article i chose was about how scientists were studying "super earth" and trying to determine wether life could survive there or not. They said that super earth, or planet d, falls in a "habitable zone" and could possibly contain water. The article says that no other planet could have the materials that we have that could make it possible for life to exist there. [] This article i found very interesting. Using telescopes scientists could see early stages of star formation. They believe this is a very rare find. The clump they observed was 100 times the mass of the Sun and they believe this mass could form 10 new stars. This finding could help better understand the formation of stars. - Tiffany Kemple

= __**Runaway planets zoom at a fraction of light speed **__ = If a star can get thrown into space at a rate of 1.5 million miles per hour, can a planet? This is a scary thought! In this article, scientist research if this can actually happen to a planet, what would happen if it did, and the probability of it happening to a planet. //"These warp-speed planets would be some of the fastest objects in our galaxy. If you lived on one of them, you'd be in for a wild ride from the center of the galaxy to the Universe at large," said astrophysicist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. // [] **By Chelsea Blanton**

Many Billions of Rocky Planets in Habitable Zones Around Red Dwarfs in Milky Way: the article explains that rocky habitable plantes have been found around red dwarfs in the milky way galaxy. astronomers think that there is a possiblily that there could be water on these planets. the article explains that there are billons of these habital planets many of them of which have a possibility of liquid water. this means we are getting closer to finding signs of life!

 * Milky Way Image Reveals Details of a Billion Stars **

[] For the first time ever, more than one billion stars in the Milky Way can be seen together in detail shown in an image captured by an international team of astronomers. Scientists made the colored picture by combining infra-red light images, instead of visible light, from telescopes. Things such as gas and dust clouds where stars have formed and died, can be seen in the image.

 * Current research is showing scientists that the magnetic field that surrounds the sun will begin to experience drastic changes in the near future. By this happening the number of solar flares and sun spots are expected to decrease. While this may sound sound like a good thing the changes within the magnetic field of the sun could damage the earth. Earth would be exposed to more of the radiation that is kept in by the suns magnetic field. As the field does its shift the amount of radiation coming from the sun will increase causing it to be impossible for air planes and space craft to exit our atmosphere due to the burns they would suffer from the suns radiation. This radiation would also cause damages to earths electronic grids and electronic devices.**

A large amount of solar storms have erupted on our Sun. These solar storms can impact life on Earth. They can disrupt electric power grids, triggering black outs and false alarms at power stations, as well as interfering with high frequency radio communications. Scientists have created a scale for the seize of the storms, and these are fortunately not as big as they can get, but future larger storms are possible threats. -Luke Bickerstaff

Can you imagine a star spiraling out of the galaxy at 300 million miles per hour? Well it is possible! Scientist have been able to successfully prove this after 7 years of study. A double star comes near a black hole which separates it sending one of the stars shooting from the galaxy. What a site that would be! But here is the real question, what if a planet was within a close orbit to one of these stars? What would happen then? Could it go spiraling out or would it be pulled into the black hole? Scientist have found the answer. -Morgan Mueller

[] The spacecraft, NASA's Two Wide-angle Imaging Neutral-atom Spectrometers (TWINS) and Interstellar Boundary Explorer (IBEX), observed the impact from inside and outside Earth's magnetosphere, respectively. The energetic neutral atom (ENA) cameras aboard each spacecraft enabled global imaging of the magnetosphere, the invisible bubble that protects Earth from the majority of charged particles from the Sun, as it compressed in response to sharply faster solar wind. -Hannah Albritton

[] They found ice formally on a dwarf planet nicknamed Snow White and now they think that they have found a thin layer of Methane as well. Scientists say that this also was a planet that had gushing volcanoes of water and that they once flowed like rivers, but now it's all frozen mush. - Elise Cortie

[] This is a very interesting article about how a star actually turned inside out. Scientist discovered this by investigating the remains of an exploded star. They used an x- ray telescope to identify different parts of the star. This is a very interesting article even thou it is kind of short. -Tommy Rutt
