Por NASA Podcast #Recomendado Tweet Gravity Assist: Meet a Space Weather Scientist, with Yaireska Collado-Vega Our Sun lights up the solar system, but it’s as not calm or predictable as it may seem. Flares and explosions called coronal mass ejections unleash fast-moving particles and radiation that pose dangers to spacecraft and astronauts alike. Yaireska Collado-Vega leads a team at NASA’s Goddard Spacecraft Center that is studying the solar weather environment so that robots and people exploring space can be protected. In this episode of Gravity Assist, she describes the excitement and challenges of understanding space weather, and how she got to be a NASA scientist.

Por NASA Podcast #Recomendado Tweet Gravity Assist: Our Sun, Our Life, with Vladimir Airapetian How well do you know the Sun? It hasn’t always looked the way it does today. Billions of years ago, the Sun was fainter but also more active, throwing out huge flares of radiation in powerful tantrums. This “young Sun” helped shape the evolution of life as we know it. By understanding what our Sun was like when life emerged on Earth, scientists can look to other stars in the galaxy and think about whether life could emerge on planets there, too. Vladimir Airapetian, scientist at NASA’s Goddard Space Flight Center, explains what researchers hope to find as they gaze beyond our solar system.

Though it may seem calm and unchanging, the Sun is dynamic. Join NASA solar scientists on a trip around the Sun, our lively and mysterious neighborhood star.

Por NASA #Recomendado Tweet Gravity Assist: The Sun’s Mysteries with Thomas Zurbuchen Back in August, NASA launched the Parker Solar Probe to study the Sun’s corona—its very outer edge. Parker will sail as close as 4 million miles from the Sun—a record for any space agency in the world—and survive temperatures up to 2,500 degrees Fahrenheit. In this week’s episode of Gravity Assist, Thomas Zurbuchen, the Associate Administrator of NASA’s Science Mission Directorate, joins NASA Chief Scientist Jim Green to discuss the mysterious we still need to solve about the Sun, and more! https://ift.tt/2UzVTfA via IFTTT
