This is a globular star cluster. It consists of 100,000 stars at least. It is about 25,000 light years away. It is 165 light years in diameter.It has red and blue giant stars, and also rejunivated blue stragglers.

Astronomer Biography Quarter 4: Margaret Geller

     Margaret Joan Geller was born on December 8th, 1947. She was born in Ithaca, New York. She became an American astronomer and also studied astrophysics. First, Margaret Geller got her Bachelor of Arts in Physics at the University of California, Berkeley in 1970. She also got her Ph.D. in Physics at Princeton University in 1975. She went on to do research fellowships at Harvard-Smithsonian Center for Astrophysics and the Institute of Astronomy in Cambridge. After this, the well established Margaret Geller became an assistant professor. She took this position at Harvard University and taught Astronomy in the years 1980 to 1938. After this, she worked at the Harvard- Smithsonian Center for Astrophysics. To this day, Geller has as many as five honorary degrees.

     Throughout her career, Geller did lots of research about cosmology and extragalactic astronomy. She constructed pioneer maps. These pioneer maps were made by Geller in the 1980s, and were a great depiction of the structure of the universe.  These maps later lead astronomers to discover the Great Wall. The Great Wall is one of the largest known superstructures in the universe and spans over hundreds of millions of light years in all directions. Margaret Geller discovered this superstructure along with John Huchra. These astronomers used redshift data to discover the Great Wall. The latest thing Geller has put research towards is creating a bigger map of the universe names the HectoMAP. In doing these things, Margaret Geller developed many different techniques that can be adopted by other astronomers. These techniques specifically help to map and learn more about structure, mass, and the relationships between galaxy clusters and large scale clusters.

Margaret Geller has received many awards for her accomplishments. Starting in 1989, she was awarded the Newcomb Cleveland Prize of the American Association for the Advancement of Science. She was awarded this along with John Huchra for their discovery of the Great Wall and for “Mapping the Universe”. Some awards were given to her for her teaching, such as the Klopsteg Memorial Award of the American Association of Physics Teachers. One of Margaret’s five total honorary degrees has been given from Colby College. Margaret Geller also obtained the MacArthur Fellowship, Russell Lectureship, Magellanic Premium, and the Schwarzschild Medal in 2014 among many others.

All in all, Margaret is a very talented astronomer that has researched and discovered many things that have changed and contributed to astronomy. The things Margaret has contributed have not only added to the information we know about the universe, but also taught other astronomers innovative ways to keep discovering more. Being one of a very little number of women in the astronomy field, Margaret Geller is inspirational to girls and has definitely paved the way for more females to get involved with sciences and astronomy.

This is the Rosette nebula. There is an open cluster. Wind is coming away from the clusters. The center is 50 million light years across. That is really big. In the picture, it looks like there is such a variety of things and different types of objects.

This is the moon Io in true color. True color means the way humans would see it in real life if we could. Sulfur and silicate rock are responsible for the bright yellow color. Io is very volcanic. Tidal gravity of Jipiter stretches Io.Some lava on Io glows in the dark. To me, it looks like a weird alien planet with the cool colors it has.

Astronomer Biography: Giovanni Schiaparelli

     Giovanni Schiaparelli was an Italian astronomer born on March 14th, 1835. He was born in Savigliano, Italy. He is known for his work studying and observing Mars, and other things in the solar system. He has had published writings, discoveries of objects, and has had awards dedicated towards him.

After being born in Savigliano, Italy, Giovanni Schiaparelli attended the University of Turin. From there, he also continued his studies at the Berlin Observatory. In the late 1850s and early 1860s, Giovanni Schiaparelli did work with the Pulkovo Observatory. Another observatory Schiaparelli did lots of work with was the Brera Observatory. Giovanni was a loyal observer at this establishment for almost 50 years.

The thing Schiaparelli is most known for is his association with our own solar system’s planet, Mars. One theory introduced by Giovanni Schiaparelli is the concept of Martian canals. Using new instruments also led him to publish a very detailed map of mars, for the time period in the 1860s to 1870s. This set an example for how astronomers mapped the things they saw, such as the observations of planets’ surfaces. On this map that he made of Mars, Giovanni Schiaparelli first made the idea of the canals. They were dark spots, that looked like maybe water had been on Mars. He names these ‘rivers’ after various rivers. Some rivers that the canals were names after were real and some were fictional.

Besides discovering many things about the planet Mars, Giovanni Schiaparelli made discoveries and observed things about comets, meteors, and meteorites. Giovanni related the fact that comets could be associated with the meteor showers observed by humans. He discovered the asteroid 69 Hesperia. Specifically, Schiaparelli showed astronomers of his time that the Leonids meteor showers and the Comet Tempel-Tuttle were closely related in terms of their orbit and timing. Giovanni also studied binary stars.

All in all, Giovanni Schiaparelli was a well established and very bright astronomer that set a standard for other astronomers. He set an example for the cartography and mapping of astronomical objects. As well as this, he discovered many interesting and thought-provoking things about Mars and it’s surface. His discoveries have inspired and led many other astronomers to build off his great work in the field of astronomy.
