NASA released a phenomenal and first-ever picture taken by Nuclear Spectroscopic Telescope Array or NuStar on Monday.
NuStar was made in 2012 to view high-energy phenomena like supernovas and black holes. Though, by snapping sun’s picture, the super-sensitive telescope is demonstrated that it could resolve a long-standing anonymity of coronal heating dilemma.
Sun is excessively vivid for other telescopes, in the same way as NASA’s Chandra X-ray Observatory. Though, NuStar’s mirrors and detectors blot out a significant part of the glare.
Fiona Harrison, NuStar’s lead researcher, said, “from the beginning I expect the entire thought was insane. Why would we have the most susceptible high-energy X-ray telescope ever made, intended to gaze deep into the universe, look at something in our own particular back yard?”
The distinctive shades in the sun’s picture uncover the anecdotal high-energy emanations. The green shades delineate energies somewhere around 2 and 3 kilo-electron volts, while blue show energies somewhere around 3 and 5 kilo-electron volts. These high-energy X-rays that stream off the sun originate from gas heated to over 3 million degrees.
The red symbolize ultraviolet light and lower-temperature material at 1 million degrees caught by NASA’s Solar Dynamics Observatory.
As indicated by NASA, the NuStar’s green and blue picture was then enclosed onto the Solar Dynamics Observatory’s red.
Researchers expect that the space telescope’s high-energy perspectives could at last resolve how the sun’s corona was an average of 1.8 million degrees Fahrenheit, while the sun’s surface heats to a sheer 10,800 degrees. Corona is the slight, gleaming atmosphere that environs the star.
As per research by the Harvard-Smithsonian Center for Astrophysics, small solar flares or nano-flares bouncing off the sun’s surface may be the cause behind it.
