Whether it’s a wonderful asteroid, a colorful aurora or a stunning eclipse, the landscape of the night sky is constantly changing. When a new guest looks like the eye, it is guaranteed to attract the attention of professional astronomers and occasional observers from the sky. Well, the Hubble Space Telescope as the paparazzi of the sky, because it controlled taking the closest photographs of the last guest to the sky to make the headlines, Comet C / 2020 F3 (NEOWISE), after its passage in front of the Sun. .
The NEOWISE comet is thought to be the brightest visual comet in the northern hemisphere since 1997, Hale-Bopp. It is estimated to have a huge speed of 40 miles depending on the second, or 144,000 miles depending on the time. The technique closest to the comet’s Sun took place on July 3 and is now heading to the outer portions of the solar system, so as not to go back in about 7,000 years.
NeoWISE Comet
Images of NASA’s Hubble Space Telescope from comet NEOWISE, taken on August 8, in the visitor’s coma, the fuel shell and guava powder that surrounds its core as it heats through the Sun. This is the first time that Hubble has photographed a comet of this luminosity in such a solution after this last passage through the Sun.
Images of comets were taken after NEOWISE flew closer to the sun on July 3, 2020, at a distance of 27 million miles (43 million kilometers). Other comets are separated due to thermal and gravitational stresses during such close encounters, however, hubble’s view shows that NEOWISE’s forged core has supposedly remained intact.
“Hubble has a much larger solution than we can get with any other telescope on this comet,” said Caltech’s leading researcher Qicheng Zhang in Pasadena, California. “This solution is essential to see the main points very close to the core. This allows us to see the settings in the dust right after their removal of this core due to the heat of the sun, by sampling the dust as close as possible to the original properties of the kite.”
The comet’s core, its icy core, is too small to be detected by Hubble. The ice ball must not be more than 4.8 kilometers (3 miles) in diameter. Instead, hubble’s symbol captures a component of the vast cloud of fuel and dust that envelops the core, which measures about 18,000 kilometers in diameter in this photo. Hubble solves a pair of central jets that come out in opposite directions. They emerge from the core in the form of dust and fuel cones, and curve into wider fan structures by rotating the core. The jets are the result of the sublimation of the ice below the surface, and the resulting dust/fuel is expelled at maximum speed.
Hubble images can help reveal the color of the comet’s dust and how those colors are replaced when the comet moves away from the Sun. This, in turn, would possibly be the way the heat of the sun affects the composition and design of this powder in the comet’s coma. The ultimate purpose here would be to know the original dust homes to be more informed about the situations of the primitive solar formula in which it was formed.
The NEOWISE comet is thought to be the brightest visual comet in the northern hemisphere since 1997, Hale-Bopp. It heads beyond the outer solar system, now traveling 144,000 miles depending on the time. I probably wouldn’t go back to the sun for about 7,000 years.
Lately, researchers are further exploring knowledge to see what they can confirm.
NASA’s NEAR-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) project first discovered the comet of the same name in March 2020. As the comet approached the Sun, the scorching heat melted its ice, releasing dust and fuel that left the signature. Cross. Throughout the summer, sky floor observers in the northern hemisphere could see the traveler move in the sky.
The Hubble Space Telescope is a task of cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, administers the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble’s clinical operations. STScI is operated for NASA through the Association of Universities for Astronomical Research in Washington, D.C.
