Biography

Margaret Burbidge
Margaret Burbidge was born in 1919 in Davenport and is currently still alive. SHe attended the University of London and got her Ph.D. there in 1943. She began to research galaxies by linking a spectrograph to telescopes. In 1951, she went to the United States to the Yerkes Observatory in Wisconsin where she had a grant. There she studied B stars and and galaxy structure. In 1953, she returned to England and researched alongside her husband, Fred Hoyle and William Alfred Fowler and came up with the B2FH theory. This theory showed how all of the elements except the very lightest are produced by nuclear reactions in stellar interiors. For this finding, they received the Warner Prize in 1959. Burbidge was admitted to the Mount Wilson Observatory, pretending to be her husband's assistance. When they realized, they eventually let her stay and continue her research. In the 1960's Burbidge obtained spectra of spiral galaxies. From these, the velocities of the ionized gas clouds in their nuclei and disks were measured. She, in collaboration with Geoff Burbidge and with Kevin Prendergast, ultimately deduced rotational properties and masses for 50 or so spiral galaxies. In 1972, she obtained directorship of the Royal Greenwich Observatory, which she held for 15 months. She became one of the foremost attackers of discrimination against women in the field of astronomy. In 1976, she became president of the American Astronomy Society. For the past 15 years, Burbidge has continued her observational research programs at the Lick Observatory of the University of California.

observation 4.1

(observations were written dow - just now posting)

partly cloudy skies

Right now, i can see the constellation Orion to the south, which has been moving farther and farther east lately. I think that i can see which stars are Betelgeuse and Rigel - Betelgeuse is a little bit more red. I can also see the bright star which i think is Sirius in the constellation Canis Major.

This is a picture taken from onboard the International Space Station. It shows a spacecraft called the Soyuz TMA-12, which is bringing new supplies to the crew on the ISS. It is amazing to me that people are actually living in a craft all the way in space. 

apod 4.6

Friday May 9th
This is a picture of a large black nebula on top of a thick field of stars. This is located in the constellation Scorpio. It is called the "dark tower" which is an allusion to Shakespeare's King Lear. This black object is almost scary and ominous against the beautiful purple sky. 

apod 4.5


Friday May 2nd
This is a picture of NGC 6188, located in the constellation Ara. The glow comes from the intense ultraviolet radiation and strong winds emitted by the young stars in this cluster which is only a few million years old. This nebula can be seen from the southern Hemisphere, but in order to see it in great detail a large telescope is needed. 

apod 4.4


Friday April 25th
This is a picture of the nebula created by the interaction of gas and dust with the light and wind from hot young stars. It is called the Fox Fur Nebula in Monocerous. I think this is a really amazing photo as the dust and light actually make it look like there is fur in the sky!

apod 4.3

This is a picture of the night sky in Sweden. There are red and green auroras that can be seen in the distant sky. The red color comes from many emission nebulas including the Heart and Soul nebula in Casseopeia. The Anrdromeda galaxy is also seen in this beautiful picture.
