    Brazil joins Artemis Accords

    [Image description: Marcos Pontes, Brazil’s minister of science, technology and innovation, signs the Artemis Accords in a June 15 ceremony in Brasilia.]

    Brazil became the 12th nation to sign the Artemis Accords, the U.S.-led effort to establish norms of behavior for space exploration, June 15.

    Marcos Pontes, Brazil’s minister of science, technology and innovation, and also the first Brazilian to go to space, signed the Artemis Accords in the Brazilian capital of Brasilia. Brazilian President Jair Bolsonaro and the country’s foreign minister, Carlos Alberto França, also attended.

    “The signing of Artemis Accords is a historic moment for Brazil. Together with the U.S. and other countries we will have the opportunity to explore the moon and initiate infinite other possibilities for international cooperation,” Pontes said in a statement.

    Brazil expressed interest in the accords shortly after the United States and seven other countries unveiled them in October 2020. In December, Pontes and then-NASA Administrator Jim Bridenstine signed a statement of intent, where Brazil said it planned to sign the accords and expressed an interest in developing a robotic lunar rover.

    Ok so this is very specific, but imagine Toby feeling guilty about not keeping up with his brother's astronaut adventures, wanting to learn more about it and going to ask josh because he knows he's kind of interested in this stuff, josh being inordinately excited about it and Toby just letting josh infodump to him about space for 3 hours

    #this will probably make more sense if u accept that josh has adhd and Has had a space hyperfixation #or something space-related #i understand space is quite a broad topic but i don't know enough to go into specifics #he did canonically have that thing with theoretical physics #which does have something to do with space i think? #also that whole episode with the nasa girl #which i do like i think but also i refuse to accept that josh wasn't interested in space before that #anyways #letting someone infodump to u is the purest form of love <3 #might make this into a short fic if i have the motivation hmm #i'll need to dust off my gcse astronomy skills lmao #the west wing #josh lyman#toby ziegler #adhd josh lyman

    The give and take of mega-flares from stars

    The long relationships between stars and the planets around them - including the Sun and the Earth - may be even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA's Chandra X-ray Observatory. from Astronomy News -- ScienceDaily https://ift.tt/3j02OgX via IFTTT

    How a supermassive black hole originates

    How do supermassive black holes in the early universe originate? A team led by a theoretical physicist has come up with an explanation: a massive seed black hole that the collapse of a dark matter halo could produce. from Astronomy News -- ScienceDaily https://ift.tt/2S7PZ9e via IFTTT

    Unwinding M51 : The arms of a grand design spiral galaxy 60,000 light-years across are unwound in this digital transformation of the magnificent 2005 Hubble Space Telescope portrait of M51. In fact, M51 is one of the original spiral nebulae, its winding arms described by a mathematical curve known as a logarithmic spiral, a spiral whose separation grows in a geometric way with increasing distance from the center. Applying logarithms to shift the pixel coordinates in the Hubble image relative to the center of M51 maps the galaxy's spiral arms into diagonal straight lines. The transformed image dramatically shows the arms themselves are traced by star formation, lined with pinkish starforming regions and young blue star clusters. Companion galaxy NGC 5195 (top) seems to alter the track of the arm in front of it though, and itself remains relatively unaffected by this unwinding of M51. Also known as the spira mirabilis, logarthimic spirals can be found in nature on all scales. For example, logarithmic spirals can also describe hurricanes, the tracks of subatomic particles in a bubble chamber and, of course, cauliflower. via NASA

    Candle Race Winner

    The great candle race of 2021 is over. The winner, by approximately an astronomical unit* is the red candle. You knew this because I bet on the blue candle. *An astronomical unit is the average distance between the Earth and the Sun.

    Mystery solved: Dust cloud led to Betelgeuse's 'Great Dimming'

    When Betelgeuse, a bright orange star in the constellation of Orion, lost more than two-thirds of its brightness in late 2019 and early 2020, astronomers were puzzled. from Astronomy News -- ScienceDaily https://ift.tt/3gAZc1X via IFTTT

    From the Guild:

    Betelgeuse burped.
    New Scientist explains that reason Betelgeuse recently appeared to dim in the sky was that it was expelling gas:
    Miguel Montargès at Sorbonne University in France and his colleagues may have got to the bottom of the mystery. They examined detailed images of Betelgeuse from the Very Large Telescope in Chile and found that the dimming was localised to the southern hemisphere of the star, which got 10 times darker than usual.
    Montargès and his colleagues ran computer simulations of the various scenarios that could have caused the Great Dimming, and found that the best match was a mix of two. In their proposed scenario, the star first ejected a bubble of gas as part of its regular evolution. Later on, part of its surface decreased in temperature because of the movement of giant blobs of plasma within the star.
    Because of that temperature drop, some of the gas in the bubble would have condensed into opaque dust, leading other parts of the gas bubble to drop in temperature and create even more dust, and therefore more dimming. This may be perfectly normal behaviour for a star like Betelgeuse, the researchers point out – we just wouldn’t spot it unless the dust cloud was aligned between us and the star.

    ALMA discovers earliest gigantic black hole storm

    Astronomers have discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe. from Astronomy News -- ScienceDaily https://ift.tt/3pXYlwD via IFTTT
