This colorized image is my tribute to astrophysicist Cecilia Payne (1900–1979), a woman who fought her way into science which was then strictly a world only for men. Cecilia discovered the chemical composition of stars and, in particular, that hydrogen and helium are the most abundant elements in stars and, therefore, in the universe. However, she is basically not credited at all with the discovery because of her male superiors.
Cecilia completed her studies at Cambridge in 1923, earning a B.A. degree in 1923. Since at that time a woman could only earn “the Title of a Degree,” she travelled to the US in 1923 to seek greater opportunities.
By the time she was awarded her PhD she had also already published six papers on stellar atmospheres, all by age 25.

Since her death in 1979, the woman who discovered what the universe is made of has not so much as received a memorial plaque. Her newspaper obituaries do not mention her greatest discovery.
Every high school student knows that Isaac Newton discovered gravity, that Charles Darwin discovered evolution, and that Albert Einstein discovered the relativity of time. But when it comes to the composition of our universe, the textbooks simply say that the most abundant atom in the universe is hydrogen. And no one ever wonders how we know.

— Jeremy Knowles, discussing the complete lack of recognition Cecilia Payne gets, even today, for her revolutionary discovery.

This is a new composite image which shows "fireworks" caused by a black hole in a nearby galaxy NGC 4258 (also known as M106). It features X-rays from Chandra (blue), radio waves from the VLA (purple), optical data from Hubble (yellow and blue), and infrared with Spitzer (red).
NGC 4258 is a spiral galaxy like the Milky Way, but it’s famous for something that our Galaxy doesn’t have – two extra spiral arms that glow in X-ray, optical, and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it. There has now been made a new study by Patrick Ogle, Lauranne Lanz and Philip Appleton from the California Institute of Technology which is explaining those spectacles. Radio shows that the supermassive black hole at the center of NGC 4258 is producing powerful jets of high-energy particles, and researchers think that these jets strike the disk of the galaxy and generate shock waves.
