Astronomers have used NASA's Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour.
The new results have been reported in a paper led by Matthew Millard, from the University of Texas at Arlington, and published in the April 20th, 2020 issue of the Astrophysical Journal.
One of the images showcases galaxy M82 or Messier 82 as it undergoes bursts of star formation.
The astronomers have also translated images of the famed Pillars of Creation into audio visualizations as well as Cassiopeia A.
It … The explanation for the high-speed material is unclear. Smith (University of Arizona), J. Morese (BoldlyGo Instituts) and A. Pagan), (X-ray: NASA/CXC; Ultraviolet: NASA/JPL-Caltech/SSC; Optical: NASA/STScI(M. Meixner)/ESA/NRAO(T.A.
Kepler's supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. In operation since 1999, it is named in honour of Subrahmanyan The 2017 work applied the same general technique as the new study, but used X-ray spectra from a different instrument on Chandra.

This allowed them to search for a companion to the white dwarf that may have been left behind after the supernova, and learn more about what triggered the explosion. Researchers used a Chandra spectrum and images obtained in 2000, 2004, 2006 and 2014 to measure the speeds of knots in the remnant.
A graphic gives a visual explanation for how motions of knots in the images and the X-ray spectra were combined to estimate the total speeds. The digital and visual cues were turned into audio signals. Use escape to clear. Three of them are labeled in a close-up view. Budding astronomers and space enthusiasts can now be able to hear the galaxy, the varying sounds representing the position and brightness of the cosmic objects that could be found in the middle of the galaxy. Kepler's supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. The image snapped by the Hubble was of the galaxy cluster Abell 2744, found millions of light-years away from Earth. The paper is also available online. NASA's Chandra X-ray Observatory is marking 20 years since the Space Shuttle Columbia launched it into space on July 23, 1999. This is about 25,000 times faster than the speed of sound on Earth. The Chandra scientists at Harvard University were able to translate images of our Milky Way galaxy into sound using a process called sonification. The volume is also controlled by the brightness of the objects. The Chandra X-ray observatory is specially developed to understand the hot, turbulent regions of space. M82 is located 12 million light-years away in the Ursa Major constellation. How chronic stress changes the brain – and what you can do to reverse the damage. How will coronavirus affect property prices? The high speeds in Kepler are similar to those scientists have seen in optical observations of supernova explosions in other galaxies only days or weeks after the explosion, well before a supernova remnant forms decades later. This audio visualization project is part of the agency’s Universe of Learning Program. Rector); Infrared: NASA/JPL-Caltech/K.

Researchers in the latest study estimated the speeds of the knots by analyzing Chandra X-ray spectra, which give the intensity of X-rays at different wavelengths, obtained in 2016. The Weather Company’s primary journalistic mission is to report on breaking weather news, the environment and the importance of science to our lives. The comparison from NASA's Hubble telescope and Chandra X-ray Observatory highlights how different the universe can look when viewed in other wavelengths of light. The X-ray spectra used by Millard and collaborators were obtained with the Chandra High Energy Transmission Grating. The four knots with the highest total speeds are all located along a horizontal band of bright X-ray emission. Sign up for daily updates for the most important
), David Burrows (Penn State University, University Park, Penn. This comparison implies that some knots in Kepler have hardly been slowed down by collisions with material surrounding the remnant in the approximately 400 years since the explosion. This asymmetry in the motions of the knots implies that the debris may not be symmetric along our line of sight, but more knots need to be studied to confirm this result. EconoTimes expressly disclaims any liability for any lost principal or profits without limitation which may arise directly or indirectly from the use of or reliance on such information. The previous eruptions of this star have resulted in a ring of hot, X-ray emitting gas about 2.3 light years in diameter surrounding these two stars.
None of the blogs or other sources of information is to be considered as constituting a track record. Optical data from Hubble (red, green, and blue) show where this collision may have triggered the star formation. X-rays from Chandra (appearing as blue and pink) show gas in outflows about 20,000 light years long that has been heated to temperatures above ten million degrees by repeated supernova explosions. © Copyright TWC Product and Technology LLC 2014, 2020. This Helix Nebula images contains infrared data from NASA's Spitzer Space Telescope (green and red), optical light from Hubble (orange and blue), ultraviolet from NASA's Galaxy Evolution Explorer (cyan), and Chandra's X-rays (appearing as white) showing the white dwarf star that formed in the center of the nebula.
As with all such advisory services, past results are never a guarantee of future results. Scientists and astronomers have been able to access the depths of the cosmic world through the help of various cutting edge technologies, which let us see the universe like never before. Millard et al. Use up and down arrows to change selection.

This phase is known as a "planetary nebula," and astronomers expect our Sun will experience this in about 5 billion years. They contain enormous amounts of superheated gas, with temperatures of tens of millions of degrees, which glows brightly in X-rays, and can be observed across millions of light years between the galaxies.

We now know that Kepler's supernova remnant is the aftermath of a so-called Type Ia supernova, where a small dense star, known as a white dwarf, reaches a critical mass limit after interacting with a companion star and undergoes a thermonuclear explosion that shatters the white dwarf and launches its remains outward. Tuesday, September 29, 2020 12:42 PM UTC, translate images of our Milky Way galaxy into sound.
This was one of the brightest supernova explosions in centuries and soon became known as Supernova 1987A (SN 87A). This image has three types of light: optical data from Hubble (appearing as white), ultraviolet (cyan) from Hubble, and X-rays from Chandra (appearing as purple emission). Astronomers aren't certain, but one candidate is in Eta Carinae, a volatile system containing two massive stars that closely orbit each other.
— Chandra Observatory (@chandraxray) September 2, 2020. When it comes to the supernova remnant, the astronomers explained that the sounds in their audio visualization of the remnant were mapped to the four elements that are found in the debris from the star and other high-energy data. They also used Chandra images obtained in 2000, 2004, 2006 and 2014 to detect changes in position of the knots and measure their speed perpendicular to our line of sight. The image is about four light years across.
Based on the Chandra spectra, eight of the 15 knots are definitely moving away from Earth, but only two are confirmed to be moving towards it. Launched on July 23, 1999, the observatory allows scientists to capture X-ray images of various high energy regions in the universe. Optical data from Hubble (orange and red) also shows evidence for this interaction in the ring.
This amazing process allowing viewers to listen to the Milky Way and other fascinating extraterrestrial objects in outer space.. A new project using sonification turns astronomical images from NASA’s Chandra X-Ray Observatory and other telescopes into sound.
