New Images Reveal the Magnetic Fields in the Horsehead Nebula
Located near the summit of Maunakea, HAWAII, the 15-meter (~49 ft) James Clerk Maxwell Telescope (JCMT) at the East Asia Observatory (EAO) is the largest telescope in the world designed to operate exclusively in the submillimetre-wavelength. In 2018, Molokai’i High School alumna Mallory Go was awarded time with the JCMT under the Maunakea Scholars program. With the assistance of EAO astronomer Dr. Harriet Parsons, Go obtained unique images of the Horsehead Nebula in polarized light, which revealed the nebula’s magnetic fields. Go (now a graduate student at Brown University) presented the images as part of a Science Fair representing Molokai`i High School. A year later, these observations were used by a team of astronomers from the Korea Astronomy and Space Science Institute (KASI), the University of Science and Technology (UST), and University College London (UCL) to perform a quantitative analysis of the strength and role of magnetic fields in the region. The paper that describes the observations and analysis, “Magnetic Fields in the Horsehead Nebula,” recently appeared in The Astronomical Journal.

Together, these instruments measure how magnetic fields in space influence the alignment of interstellar dust. As Dr. Parsons explained in an EAO press release: “You can think of POL-2 as a pair of polarized sunglasses sitting in front of the telescope. In Hawaii, many of us are used to wearing polarized sunglasses – they help us to see better by cutting down glare – but at the telescope, by rotating the polarized lenses, we analyze the brightness of the light being observed and deduce if it is under the effect of magnetic fields. Astronomers can look at clouds of gas and dust using such instruments – regions both within our own galaxy or beyond – and expand their understanding of what shapes them.” The astronomers from KASI, UST, and UCL obtained additional data using the JCMT’s other operational instruments – the Heterodyne Array Receiver Program (HARP) and Auto Correlation Spectral Imaging System (ACSIS) – to measure showed how bright and dense the region. The HARP instrument revealed additional spectral line data that showed the presence of a type of carbon monoxide containing oxygen-18 (C18O), a stable isotope of oxygen thought to originate in molecular clouds. Said UCL astronomer Dr. Kate Pattle, one of the study’s co-authors: “The data are impressive and what they tell us is even more impressive. I am delighted that Mallory has given us the chance to work on such a beautiful and iconic region of the sky – and what we’ve found helps us to understand why the Horsehead Nebula has the shape that it does. These observations tell us a story of two dense regions hidden in the Horsehead. We see a ridge of warm gas and dust – the head and mane of the horse – that is interacting with the ultraviolet photons from nearby bright young stars.” This first light image from the Callisto telescope at the SPECULOOS Southern Observatory (SSO) shows the famous Horsehead Nebula.

Jehin/ESO The JCMT’s instruments allowed the team to observe the interaction between the nebula’s “head” and “mane” and nearby young stars – which appears to have had a noticeable effect on the nebula’s magnetic field. The team theorized that it folded back on itself along the observatory’s line of sight as the Horsehead Nebula formed. Behind this ridge, they observed a cold clump of dense material that appeared to have been sheltered from these interactions – which they suspect will go on to form a new star system. This made the observations especially exciting, as they have allowed astronomers to see what magnetic field lines in regions like the Horsehead Nebula are doing for the first time. As Pattle added: “This gives us important insight into how stars can continue to form even in regions like the Horsehead, where the cold gas that provides the material for new stars is being eroded by photons from nearby young and hot stars. We expect that our own Sun formed as part of a cluster of stars, and so looking at how stars form in the Horsehead Nebula may give us an insight into our own Solar System’s past.” Though it is an iconic astronomical object, Go’s observations were the first time anyone had attempted to visualize its magnetic field. “When I heard about the Maunakea Scholars program, I was excited,” said Go. “It seemed to me to be such a fantastic opportunity to use the Telescopes on Maunakea. I chose to study the Horsehead Nebula because I thought it was beautiful, and I didn’t find much research on it.” Further Reading: James Clerk Maxwell Observatory, The Astronomical Journal The post New Images Reveal the Magnetic Fields in the Horsehead Nebula appeared first on Universe Today.

Star Wars Director Says It's About Time A Woman Makes A Star Wars Movie
Jan 02, 2024
Oscar-winning documentary filmmaker Sharmeed Obaid-Chinoy is directing an upcoming Star Wars movie that brings back Daisy Ridley in the role of Rey. Obaid-Chinoy will become the first woman to direct a Star Wars film, dating back to the franchise's origins in the 1970s. Speaking about this, Obaid-Chinoy told CNN that she is "very thrilled" to make the movie and create something that is "very special.""We're in 2024 now, and I think it's about time we had a woman come forward to shape the story in a galaxy far, far away," she said.Obaid-Chinoy won Best Documentary, Short Subjects Academy Awards for Saving Face (2012) and A Girl in the River: The Price of Forgiveness (2015).In 2020, Lucasfilm boss Kathleen Kennedy told the BBC that a woman would eventually direct a Star Wars movie, saying that would "absolutely" happen, "without question." Victoria Mahoney was a second unit director on The Rise of Skywalker, but a woman has never claimed a top directing credit on a Star Wars movie.On the TV side of things, The Mandalorian has featured a number of female directors, including Deborah Chow and Bryce Dallas Howard. Chow went on to direct the Obi-Wan TV series, too.Another high-profile franchise that has never had a female director is James Bond. Producer Barbara Broccoli and Skyfall director Sam Mendes have both said they want to see a woman direct a future 007 film.As for Obaid-Chinoy's Star Wars movie, little is known about it apart from the fact that Ridley will come back to play Rey. It is expected that this film will be the first of the three new Star Wars films to come to theaters, possibly releasing in December 2025.According to a report, Peaky Blinders creator Steven Knight is writing the Rey movie, taking over for Damon Lindelof and Justin Britt-Gibson.

Jan 02, 2024 15:29
The NBA named Clare Akamanzi – an accomplished business executive and international trade and investment lawyer – as CEO of NBA Africa. Akamanzi will start her position on Jan. 23, 2024, and report to NBA Deputy Commissioner and Chief Operating Officer Mark Tatum. In this role, Akamanzi will oversee the NBA’s business and basketball development efforts in Africa and will be responsible for continuing to grow the popularity of basketball, the NBA and the Basketball Africa League (BAL) across the continent, including through grassroots basketball development, media distribution, corporate partnerships, and social responsibility initiatives that improve the livelihoods of African youth and families. For the last six and a half years, Akamanzi was CEO of Rwanda Development Board (RDB), where she spearheaded Rwanda’s economic development by enabling private sector growth. Under Akamanzi’s leadership, RDB implemented several business policy reforms and initiatives that led to significant investment and development for the country, including through partnerships with the BAL, Arsenal FC, Paris Saint-Germain FC, FC Bayern Munich and TIME Magazine, among others. “Clare’s business acumen, international experience and familiarity with basketball and the NBA make her the ideal executive to lead our business in Africa,” says Tatum. “NBA Africa and the Basketball Africa League are well-positioned for continued growth, and under Clare’s leadership we believe these initiatives will transform economies, communities and lives across the continent.” “I’ve seen firsthand how sports can positively impact businesses, families and communities in Africa, and the NBA and the BAL are a perfect example of that,” says Akamanzi. “The NBA has done an incredible job growing basketball and the economy around it across the continent, and I’m excited about the enormous opportunities ahead to build on that momentum.” Previously, Akamanzi was Chief Operating Officer of RDB and Head of Strategy and Policy Unit, Office of the President of the Republic of Rwanda. She has extensive international trade, business and diplomatic experience, having previously worked for the Rwandan Government at the World Trade Organization in Geneva, Switzerland and at the Rwandan Embassy in London, England. Akamanzi has worked or studied in seven different countries and holds an honorary LLD from Concordia University in Montreal, Canada, in recognition of her work in Rwanda. She earned a master’s degree in public administration from Harvard University’s Kennedy School of Government in Cambridge, Massachusetts, where she was the recipient of three prestigious awards for academic excellence and distinguished contribution to the community: the Lucius N. Littauer Fellows Award, the Raymond & Josephine Vernon Award and the Robert Kennedy Public Service Award. In addition, Akamanzi holds a Master of Laws degree in international trade and investments from the University of Pretoria in South Africa, and a Bachelor of Laws degree from Makerere University in Kampala, Uganda. Akamanzi has served on several company boards, including the World Health Organization (WHO) Foundation, ECOBANK and Aviation, Travel and Logistics (ATL) company. She was recognized by Forbes as one of Africa’s Top 50 Powerful Women in 2020.
