  • Data from Webb and Hubble provide a comprehensive view of M74.

    Researchers created an image of Phantom Galaxy M74 using data from the Hubble telescope and the Webb telescope, an image provided by the NASA/ESA/CSA James Webb Space Telescope and data from the NASA/ESA Hubble Space Telescope to provide a comprehensive view of the are complementary to the other.

    M74 is a special class of spiral galaxy known as the ‘Grand Design Spiral’ because it has two clearly defined spiral arms, like the Milky Way, with its arms radiating outwards. Its spiral arms are prominent and well defined, and are in contrast to the patchy and ragged structure seen in some spiral galaxies.

    Taken by Webb’s sharp vision, the image of M74 reveals delicate filaments of gas and dust in M74’s gorgeous spiral arms, which wind out through the center of the image, The nuclear region of the galaxy’s center lacking gas provides a vague view of the nuclear star cluster. Researchers looked into M74 with Webb’s Mid-Infrared Instrument (MIRI) to gain insight into what were the early stages of star formation in the local universe.

    These observations by Webb are part of a larger effort by the international PHANGS collaboration to chart 19 nearby star-forming galaxies in the infrared. Researchers combine crystal-clear Webb observations at longer wavelengths, so that the explorer can pinpoint star-forming regions in galaxies, and accurately measure the age of the mass of star clusters, and the tiny specks of dust flowing into interstellar space, To allow us to gain insight into the nature of grains.

    Researchers reveal bright regions of star formation from M74’s Hubble observations, known as HII regions, Hubble’s sharp vision complements Webb’s unique sensitivity at the infrared wavelengths ultraviolet and Hubble’s sharp vision at visible wavelengths, Because the Atacama Large Millimeter/submillimeter Array makes observations with ground-based radio telescopes such as ALMA.

  • The image of the globular cluster NGC 6540 has been captured by the Hubble telescope.

    An image of the globular cluster NGC 6540, taken by the NASA/ESA Hubble Space Telescope, shows that both the Hubble Telescope’s instruments Wide Field Camera 3 and the Advanced Camera have slightly different fields of image, both of Hubble’s cameras determine, That’s how large a sky area each device takes up. This Hubble image shows the starry region in the sky captured by both instruments, NGC 6540 being a globular cluster, and a cluster of stable stars like the rest of the globular cluster.

    The population of stars in globular cluster clusters can range from tens of thousands to millions of stars, and all of them are trapped in a cluster due to their mutual gravitational attraction. The brightest stars in this image from Hubble are adorned with prominent cross-shaped patterns of light, known as diffraction spikes, the diffraction spikes being lines emanating from bright light sources, known in photographs and in vision as the starburst effect or sunstar.

    The star’s light when it enters the telescope is slightly different from its internal structure, as bright objects are surrounded by spikes of light, observed by Hubble at the center of NGC 6540, to help researchers determine the age, size and shape of the globular clusters. to measure structures. The gas and dust covering the center of our galaxy blocks some of the light from globular clusters, causing the globular cluster’s stars to change colour.

    Astronomers believe that globular clusters provide insight into the early history of the Milky Way, so studying them can help us understand how our galaxy evolved.

  • Jupiter has been captured by Webb’s Near-Infrared Camera (NIRCam).

    The James Webb Space Telescope has captured new images of Jupiter, helping them understand Jupiter’s inner life more precisely, Webb’s observations provide scientists with even more clues about Jupiter.

    Jupiter is a gaseous planet, and there are countless activities happening, such as the movement of giant storms and powerful winds, the appearance of auroras at Jupiter’s poles. is accelerated, and when the particles hit the atmosphere near the magnetic poles, glow like gases in a fluorescent light fixture.

    Webb’s Near-Infrared Camera (NIRCam) is used for this image of Jupiter, which has three special infrared filters, which display the details of the planet. Our eyes are able to see only in visible light, since infrared light is invisible to our eyes, so the light is mapped on the visible spectrum.

    Scientists collaborated with citizen scientist Judy Schmidt to translate the Webb data into images, and the image was created by combining several images from Webb, including visible auroras from high altitudes above both the north and south poles of Jupiter are spread.

  • Supergiant star Betelgeuse has blown off his top.

    A team of researchers, studying data from the NASA Hubble Telescope and other observatories, found that the supergiant star Betelgeuse blew off its top, lost a large part of its visible surface, and caused a massive surface mass ejection. SMEs) are produced. Ejections (SMEs) are an action in which there is a significant release of plasma from the Sun’s corona into the heliosphere, as well as the accompanying magnetic field, that results in the Sun regularly blowing away parts of its weak outer atmosphere, the corona, But the Betelgeuse SME has erupted 400 billion times more massive than a normal CME, and is slowly recovering from this devastating upheaval.

    Andrea Dupree of the Center for Astrophysics says that while “Betelgeuse is doing some unusual things right now, and the interior is bouncing, new observations from Harvard and the Smithsonian in Cambridge, Massachusetts provide clues, how a red star appears late in its life.” This is because their nuclear fusion furnaces burn out before a supernova can explode. The amount of mass loss of red stars significantly affects their fate, but Betelgeuse’s surprising form There is no evidence that the star is going to die out any time soon, and no mass loss event is a sign of an imminent explosion.

    Dupree depicts a coherent story of a never-before-seen, Titanic spasm in an aging star, in which he has put together all the puzzle pieces of the star’s petulant behavior before, after and during the explosion in one image. For this, Dupree used the STELLA Robotic Observatory, Fred L. Whipple Observatory’s Tillinghast Reflector Echelle Spectrograph (TRES), NASA’s Solar Terrestrial Relations Observatory spacecraft (STEREO-A), NASA’s Hubble Space Telescope and the American Association of Variables’ New Spectroscopic and Imaging Helped with data. The star observer (AAVSO) has played a key role in solving the mystery, says Dupree, adding that we have never seen a massive mass ejection of a star’s surface before, this is an entirely new phenomenon, which we can directly observe by Hubble and resolve the details of its surface.

    The supergiant star Betelgeuse has scattered fragments of the photosphere into space, and those that survived have cooled to form a dust cloud that has blocked light from the star, as seen by Earth observers. In 2019, researchers observed the changing brightness of the supergiant star Betelgeuse, which lasted for a few months, one of the brightest stars in the sky, found in the right shoulder of the constellation Orion, research shows, The supergiant’s 400-day pulsation rate is now running, at least temporarily.

    For nearly 200 years, astronomers have clearly measured this rhythm as Betelgeuse’s brightness variations and changes in surface motions, and its disruption attests to the speed of the strike. Betelgeuse is now so massive, that if it replaced the Sun at the center of our solar system, this outer surface would extend beyond the orbit of Jupiter, Dupree told Hubble in 1996 to resolve hot spots on the star’s surface, This was the first direct image of a star other than the Sun.

  • The outer region of the solar system where icy bodies and comets are present.

    Our solar system is full of many unknown things, of which we know many things, and some are still unknown, from the planet closest to the Sun and many unknown things to the boundary of the solar system. If we have a spacecraft whose speed is even 10% of that of light, and we go outside the solar system from this spacecraft, then we get to see many things on the way, such as asteroids, comets, Kuiper belt Objects – Rock, metal and all kinds of small and large bodies of ice etc. All the objects present in the solar system are from the time of creation, many of these objects have been formed with the formation of planets, such as asteroids, comets, meteors and meteorites etc., all these objects are in constant motion, because they revolve around the sun, What these objects of the Solar System have always fascinated researchers are.

    Those unknown objects, which have fascinated researchers, have made them wonder, why are they different from each other? About 186 billion miles (300 billion kilometers) from the Sun is a group of icy objects known as the Oort Cloud, which orbit the entire Solar System in a plane plane like a planet, the Oort Cloud covers the entire Solar System. It is surrounded by a huge circular circle, about 100,000 AU in width (100,000 times the distance between the Earth and the Sun). Oort cloud is considered to be the last boundary of the solar system, because after this the interstellar starts, if any object or comet from the Oort cloud orbits the Sun, then its orbital period can be thousands or even millions of years, you In this way, we can also understand that when it takes about 30,000 years for NASA’s Voyager 1 to cross the Oort cloud and completely exit our solar system, then what can be the orbital period of a comet.

    Most of the objects in the Oort cloud may be made of ice, which can be the size of mountains, because the Oort cloud comes in an area where sunlight has little effect, and here the temperature remains at minus, This is the reason why there are more icy bodies in the Oort cloud. Perhaps sometime in the future, Oort may test the large icy bodies of the cloud, but NASA and other space agencies have a whole flotilla of robotic spacecraft with which to closely explore the smaller worlds that lie within the Solar System.

  • The Hubble Telescope studies a star-studded skyfield.

     

    In 1784 astronomer William Herschel discovered the globular cluster NGC 6638 by an 18.7-inch telescope and later in the New General Catalog, NGC 6638 is a globular cluster located in the constellation Sagittarius, Hubble’s image showing the heart of this globular cluster NGC 6638. shows. The stars are scattered throughout this globular cluster, and for observation, researchers shed light on the star density at the center of NGC 6638, where the stars are stable and tightly bound, a cluster of thousands to millions of stars.


     To capture the image of NGC 6638, researchers used two of Hubble’s state-of-the-art astronomical instruments, the Wide Field Camera 3 and the Advanced Camera for Surveys, Hubble has been instrumental in helping scientists understand the globular cluster. It is impossible for ground-based telescopes to clearly distinguish the stars in the core of the globular cluster NGC 6638, as distortions caused by Earth’s atmosphere are not possible to see clearly.


     It is not possible to clearly see globular clusters with any ground-based telescopes, so researchers enlisted the help of Hubble, because Hubble can study any objects orbiting the Earth about 340 miles (550 km) above, The Hubble Telescope has the property that it can reveal what types of stars form globular clusters, how they develop. After the Hubble Telescope, the James Webb Space Telescope will study globular clusters, webb can see star-studded interiors, which are not possible to see by Hubble, because the Webb telescope observes any object at infrared wavelengths.

  • Webb images show us things that were not possible to see before.

    Six months after Webb’s launch, NASA unveiled the first operational images of Webb to new depths and worlds, and with it the beginning of the revolutionary era of the Webb telescope, it’s not wrong to say. Webb will give researchers the opportunity to study every phase of this vast cosmic history, spanning 13.5 billion years,…

  • Zeta Ophiuchi star will leave its birthplace in the future.

    About 440 light-years away from Earth is a hot star known as Zeta Ophiuchi, the only star in the constellation of Ophiuchus, with an apparent visual magnitude of 2.57. Researchers believe that Zeta Ophiuchi likely left its birthplace due to a powerful stellar explosion, NASA’s Chandra X-ray Observatory tells the story of Zeta Ophiuchi, how it left its birthplace.

    Zeta Ophiuchi is 20 times larger than the Sun, thanks to research suggesting that Zeta Ophiuchi was in close orbit with another star when it separated from its companion, a million years before Zeta Ophiuchi in a supernova explosion, The partner was destroyed. Released by NASA’s Spitzer Space Telescope, new images of infrared data reveal a spectacular shock wave (red and green) created by a burst of matter flying away from the surface of the star and gas in its path.

    Data from the Chandra X-ray Observatory show the X-ray emission (blue) around the star as a bubble formed by gas, heated to millions of degrees by the impact of the shock wave.

    A team of astronomers led by Samuel Green of the Dublin Institute for Advanced Studies in Ireland has built the first detailed computer model of a shock wave that can interpret data obtained at a variety of wavelengths, including optical, infrared and radio observations. Created by astronomers, three of the computer models predict a faint X-ray emission from one of the models, the other two computer models predict the intensification of the X-ray emission near the shock wave.
