Liam Payne's real-life girlfriend Sophia Smith was involved in the shoot, but did not appear on-screen. This was the last video of One Direction with the member Zayn as he departed from the band on 25 March 2015. The official music video was released on 21 November 2014 and directed by Ben Winston. 2 minutes and 28 seconds into the song, the key changes to B♭ major. The harmonies in the chorus, backed by rounds of "Oohs", give the song added depth and a "big contemplative feel." The song runs for 3 minutes and 47 seconds and begins in the key of A♭ major. Composition and lyrics ĭeveloping on the themes of " Live While We're Young" and " Story of My Life", the song explores the rapid passage of time, seizing the moment in life, and gaining love along the way. The track was released on 14 November 2014, three days before the album's release.

"We'll be analyzing the results for decades to come." "This is going to be groundbreaking in terms of X-ray data acquisition," Weisskopf said. The telescopes will observe the X-rays and feed them into the detectors, which can capture images of the X-rays and measure their polarization. The satellite's eyes on the universe include sensitive polarization detectors, which were made in Italy. Better yet, we may find whole lists of new questions to ask!" "There may be even more exciting answers ahead than the ones we've hypothesized. "IXPE will help us test and refine our theories of how the universe works," Weisskopf said. This perspective on extreme cosmic objects could also reveal the answers to larger fundamental questions about physics. Using IXPE to study the polarization of cosmic X-rays could help scientists better understand the remnants of exploded stars, like black holes and neutron stars, their environments and how they produce X-rays. While waves of light can vibrate in any direction, polarized light only vibrates in one direction. Polarized light also bears the unique stamp of its source and what it passed through on the way.
This is why scientists rely on X-ray telescopes in space.
This light is practically encoded with the signature of what created it, but Earth's atmosphere prevents X-rays from reaching the ground. In space, this includes powerful magnetic fields, collisions between objects, explosions, scorching temperatures and rapid rotations. X-rays are a highly energetic wavelength of light that are born from extremes. "IXPE will tell us more about the precise nature of cosmic X-ray sources than we can learn by studying their brightness and color spectrum alone." "The launch of IXPE marks a bold and unique step forward for X-ray astronomy," said Martin Weisskopf, IXPE's principal investigator, in a statement. The satellite will be able to see an often overlooked aspect of cosmic ray sources called polarization. While IXPE isn't as big as NASA's Chandra X-ray observatory, it is the first space observatory of its kind. The spacecraft, which is the collaborative effort of NASA and the Italian Space Agency, carries three telescopes. ET Thursday aboard a SpaceX Falcon 9 rocket from NASA's Kennedy Space Center in Florida. The satellite successfully launched at 1 a.m. In the early morning hours Thursday, NASA launched its Imaging X-ray Polarimetry Explorer mission, or IXPE, to measure X-rays released by black holes and neutron stars. CNN - We're about to get a new perspective on some of the most extreme objects in the universe.
