As a young girl growing up in small-town Vermont, Aki Roberge dreamed of other worlds.
An avid science fiction fan, she wondered if the kinds of planets she saw in the âStar Warsâ movies, with their varied climates and cultures, creatures and civilizations, might really exist.
Today, and for more than a decade now, she actually explores such possibilities, searching not for parched Tatooine or ice-clad Hoth, but for real exoplanets â planets orbiting other stars.
Dr. Aki Roberge, a research scientist in NASAâs Exoplanet and Stellar Astrophysics Lab at the Goddard Space Flight Center in Maryland, right outside Washington, D.C., will talk about her life, her work and the latest breakthroughs in this relatively new branch of astronomy at 7 p.m. Friday. Itâs part of Wyoming Stargazingâs âThe World Above the Tetonsâ speaker series.

A research team led by Professor Soebur Razzaque from the University of Johannesburg predicted gamma-ray burst (GRB) behaviour. One such burst recently disrupted cell phone reception in South Africa. While Earth gets blasted by mild short GRBs regularly, the research team found that giant flare GRB 200415A came from another possible source.
It erupted from a very rare, powerful neutron star called a magnetar, a star dying soon after the beginning of the Universe. Their findings were published in

GRB explosions can disrupt mobile phone reception on Earth. Prof Razzaque explains that when a star dies, “it will get bigger and become a red giant star. After that it will collapse into a small compact star called a white dwarf”.
