"When I’m asked about the relevance to Black people of what I do, I take that as an affront. It presupposes that Black people have never been involved in exploring the heavens, but this is not so. Ancient African empires — Mali, Songhai, Egypt — had scientists, astronomers. The fact is that space and its resources belong to all of us, not to any one group."

— Dr. Mae Jemison, the first African-American woman in space.

As we admire these women this month, we must also remember how difficult of a journey they must have had. And we must make a commitment to make the journey easier for little Black girls who are interested in science.

In her book Swimming Against the Tide: African American Girls and Science Education, Sandra Hanson explodes the myth that black girls are somehow disinterested in science due to hyper-religiosity or “culture.”   Hanson found that, despite significant institutional and societal barriers, there is greater interest in science among African American girls than in other student populations. She frames this seeming paradox in historical context, stressing that “Early ideologies about natural inequalities by race influenced the work of scientists and scholars as well as the treatment of minorities in the science domain.  Racism is a key feature of science in the United States and elsewhere.  This has a large impact on the potential for success among minority students.  Early work on science as fair has not been supported.”

Hanson outlines some of the obstacles that confront budding African American women scientists from elementary school to the postgraduate level.  Stereotypes about girls of color lacking proficiency in science, the absence of nurturing mentors, the dearth of education about people of color who have contributed to science research (i.e., culturally responsive science instruction), and academic isolation often deter youth who would like to pursue science careers.


Conservatives who disdain “liberal multiculturalism” in higher education dismiss such concerns about diversity in hiring as handwringing.  According to this view there is only one standard academia should use; objective and unbiased, untainted by affirmative action.

Yet white students are beneficiaries of cradle to grave affirmative action.  White students grow up seeing the dominant image of rational, trailblazing scientific discovery (from films like Dr. Strangelove to 2001: A Space Odyssey to Close Encounters to The Right Stuff) as spearheaded by courageous rugged individualist generally white males.  They are socialized to believe in a template of “purely” meritocratic success and individual achievement. Meritocracy becomes gospel and lucre.  They can take it to the bank and use it to repel the less qualified savages.

While she was at UCLA Devin Waller was the only African American woman in the Astrophysics department. On the first day of her upper division classes she recalls being asked by male students befuddled by her presence whether or not they “were in the right class.” Since peer networking and study groups in science departments are largely white and male, white academic success and scholarly legitimacy in science become a self-fulfilling prophecy. For black women in white male dominated professions, showing vulnerability and having any kind of public failure are simply not options. Like many women of color Devin’s approach was that “You kind of go in there and set a precedent. Everything you do is watched. You have to establish yourself as intelligent. There were no black women in my classes. No one who looked like me.”

Not having anyone who looks like them as a faculty member, administrator and/or mentor influences the sense of isolation, anxiety, and burnout that students of color often experience in science disciplines.  As an Electrical Engineering major Kimberly Bryant, founder of Black Girls Code, a nonprofit dedicated to developing African American girls as computer programmers, also found herself “feeling culturally isolated” during college.  On her website she argues that  the “dearth of African-American women in science, technology, engineering and math professions…cannot be explained by, say, a lack of interest in these fields. Lack of access and lack of exposure to STEM topics are the likelier culprits.”

In her autobiography Find Where the Wind Goes: Moments from My Life, Mae Carol Jemison (the first black woman astronaut and first woman of color in space) reflects on how, after professing interest in being a scientist to one of her teachers, she was told to set her sights on being a nurse instead.  As a sixteen year-old undergraduate at Stanford University, Jemison was practically shunned by her physical science instructors.  Although her experiences occurred during the sixties and seventies, the dominant view of who is a proper scientist has not changed and nursing is still a more acceptable aspiration for black women who are culturally expected to be self-sacrificing caregivers for everyone in the universe.

Astrophotography by Jason Jennings

When being a person gets stressful, as it tends to do, I sometimes take time out to just appreciate this strange and bewitching universe. I fill my head with thoughts of the stellar winds of a thousand newborn stars; of images we’ve captured of ancient galaxies nearly as old as the universe itself; of distant worlds with triple-sunned-skies; of comets in the Oort Cloud plunging around the sun like a cloud of electrons around the burning heart of our atomic solar system… And I have to remind myself that these places actually exist in the same world as exams and crippling anxiety and politics and terrorism and poverty. But I don’t wonder at the universe’s vastness to make myself feel small or make my problems seem less significant—instead, I take comfort in the fact that I’m directly connected to the stars, and that no matter what happens, I’ll always belong to the universe as a little part of an immense cosmic ecosystem.

“To observe how winds move high in Earth’s atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around – but scientists have no similar technique to study the turbulent atmosphere of the Sun. So researchers were excited in December 2011, when Comet Lovejoy swept right through the sun’s corona with its long tail streaming behind it. 

I captured images of the comet, showing how its long tail was buffeted by systems around the Sun, offering scientists a unique way of observing movement as if they’d orchestrated the experiment themselves. Since comet tails have ionized gases, they are also affected by the Sun’s magnetic field, and can act as tracers of the complex magnetic system higher up in the atmosphere. Comets can also aid in the study of coronal mass ejections and the solar wind.”

Earth at Night
This new global view of Earth’s city lights is a composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (NPP) satellite.

The data was acquired over nine days in April 2012 and 13 days in October 2012. It took 312 orbits to get a clear shot of every parcel of Earth’s land surface and islands. This new data was then mapped over existing Blue Marble imagery of Earth to provide a realistic view of the planet.
The image was made possible by the satellite’s “day-night band” of the Visible Infrared Imaging Radiometer Suite, which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires and reflected moonlight.
The day-night band observed Hurricane Sandy, illuminated by moonlight, making landfall over New Jersey on the evening of Oct. 29. Night images showed the widespread power outages that left millions in darkness in the wake of the storm.

 Saturn and Venus meet in the dawn sky this week 
For the last month or two, the planet Saturn has been on the far side of the sun, but emerges this week at dawn right next to the brilliant planet Venus.
Most of the planets appear to move from west to east against the background stars: right to left in the Northern Hemisphere and left to right in the Southern Hemisphere. Things are a little bit different when we are referring to rising planets in the dawn sky, relative to the point of sunrise.
In this case, both Venus and Saturn are on the far side of the sun, viewed from the moving planet Earth. The result is that Saturn appears to be moving away from the sun while Venus appears to be moving towards the sun. The two planets will appear to pass on the morning of Tuesday, Nov. 27, when they will be separated by about the width of the moon.
On Tuesday morning, the two planets will fit within a low-power telescope field, providing a striking visual contrast.
Venus is close to the sun and close to us, which combine to make it very bright. Saturn is far from the sun and far from Earth, combining to make it appear very dim in contrast to brilliant Venus.
Venus is a bright but featureless white gibbous shape, 87-percent illuminated, like a miniature version of the moon when it is four days past full, while Saturn is girdled by its famous rings.
Although Venus is much closer to us than Saturn, 1.4 astronomical units away (130 million miles, or 209 million kilometers), as compared to Saturn at 10.6 astronomical units (985 million miles, or 1.5 billion km), the two appear almost the same size in the telescope, because Saturn is a much larger planet than Venus.
This juxtaposition of Saturn and Venus in the sky is what astronomers call a conjunction, a fairly common event. It also forms a three-object alignment: Saturn, Venus, and Earth fall very close to a straight line.
There will be an even closer alignment of three solar system bodies on Dec.  21 this year. This is not the alignment you may have heard of associated with the 2012 Mayan apocalypse hoax.
On Dec. 21, there will be a transit of Venus visible only from the planet Saturn. Like the transit of Venus visible from Earth earlier this year, the planet Venus will appear to cross the face of he sun, but you would have to be near Saturn to see it. This is another three-object alignment: sun, Venus, and Saturn.
There are, of course, no humans anywhere near Saturn, but there is a sophisticated probe named Cassini in orbit around Saturn, and astronomers plan to use Cassini to observe this transit.
As to that other “planetary alignment” predicted for Dec. 21, supposedly involving all 8 planets, that is quite simply impossible. In fact, all 8 planets have never aligned, not even once, in the entire 4 billion plus years that the solar system has existed.
Because the changing positions of Saturn and Venus will make an interesting dance in the predawn sky, plan on observing a few mornings before and after the date of closest approach on Nov. 27. This is an excellent photo opportunity, and we will welcome your pictures of this event.
Editor’s note: If you snap an amazing photo of Saturn and Venus, or any other night sky view, and you’d like to share for a possible story or image gallery, send images, comments and observing location information to managing editor Tariq Malik at tmalik@space.com.
