Instagravity: політати над Сонцем і крізь галактики

Віртуальні тури між зірками від центру космічних польотів NASA


Inspired збирає Instagram-профілі, за якими варто стежити

В Міжнародний день польоту людини у космос і День працівників ракетно-космічної галузі України пропонуємо подивитися відео з інстаграму центру космічних польотів імені Ґоддарда. Це велика дослідницька лабораторія NASA, що була заснована в 1959 році. В цьому Instagram-профілі можна знайти інформацію про проекти NASA та переглянути відео і фото з космосу.

Send your name to the Sun! ?☀ go.nasa.gov/HotTicket . @NASA’s Parker Solar Probe will revolutionize our understanding of the Sun; it will swoop to within 4 million miles of the Sun’s surface, facing heat and radiation like no spacecraft before it. Launching in 2018, Parker Solar Probe will provide new data on solar activity and make critical contributions to our ability to forecast major space weather events that impact life on Earth. . Be a part of the first mission to touch the Sun! Submit your name to be included on a memory card that will fly aboard the Parker Solar Probe spacecraft at go.nasa.gov/HotTicket. Deadline April 27, 2018. . Credit: NASA’s Goddard Space Flight Center/Genna Duberstein . #nasa #sun #beautiful #space #science #astronomy #nasagoddard

NASA scientist are searching for a somewhat unusual substance, missing dark matter in an oddball galaxy. [via @NASAHubble] . Researchers were surprised when they uncovered a galaxy that is missing most, if not all, of its dark matter. An invisible substance, dark matter is the underlying scaffolding upon which galaxies are built. It’s the glue that holds the visible matter in galaxies — stars and gas — together. . “We thought that every galaxy had dark matter and that dark matter is how a galaxy begins,” said Pieter van Dokkum of Yale University in New Haven, Connecticut, lead researcher of the Hubble observations. “This invisible, mysterious substance is the most dominant aspect of any galaxy. So finding a galaxy without it is unexpected. It challenges the standard ideas of how we think galaxies work, and it shows that dark matter is real: it has its own separate existence apart from other components of galaxies. This result also suggests that there may be more than one way to form a galaxy.” .

@NASAHubble’s Orion Nebula – 360° Video . This visualization journeys into the famous star-forming region of the Orion Nebula based on an image from the Hubble Space Telescope. This exhilarating trip begins by flying through a layer of gas above the nebula, called the “veil.” The descent to the gaseous surface provides an overview of the structure of the region as the winds and radiation from the central cluster have carved out a long “valley” in the cloud. The massive bright stars are responsible for heating the gas to temperatures at which it glows. . To view the 360° video go to: facebook.com/NASASHubble .

Hubble’s Celestial Snow Globe ❄?? . It’s beginning to look a lot like the holiday season in this @NASAHubble image of a blizzard of stars, which resembles a swirling snowstorm in a snow globe. . The stars are residents of the globular star cluster Messier 79, or M79, located 41,000 light-years from Earth, in the constellation Lepus. The cluster is also known as NGC 1904. Globular clusters are gravitationally bound groupings of as many as 1 million stars. M79 contains about 150,000 stars packed into an area measuring only 118 light-years across. These giant “star-globes” contain some of the oldest stars in our galaxy, estimated to be 11.7 billion years old. . This video starts with a wide-field view of the sky covering the constellations of Orion, the hunter, and Lepus, the hare. The view zooms down to the relatively tiny field of the Hubble image of globular star cluster Messier 79 (M79). The sequence then dissolves to a visualization of a rotating star cluster that provides three-dimensional perspective. The simulated star cluster is modeled to reflect the number, color, and distribution of stars in M79, but not its exact structure. Finally, the scene pulls back to reveal a special holiday greeting. . In the Hubble image, Sun-like stars appear yellow. The reddish stars are bright giants that represent the final stages of a star’s life. Most of the blue stars sprinkled throughout the cluster are aging “helium-burning” stars. These bright blue stars have exhausted their hydrogen fuel and are now fusing helium in their cores. . A scattering of fainter blue stars are “blue stragglers.” These unusual stars glow in blue light, mimicking the appearance of hot, young stars. Blue stragglers form either by the merger of stars in a binary system or by the collision of two unrelated stars in M79’s crowded core. . Credit: NASA and ESA, Acknowledgment: S.
