The Webb telescope captured an image of a region called the "Pillars of Creation".

In 1995, the Hubble Telescope took the first image of a region known as the "Pillars of Creation" within the Eagle Nebula, which became world famous, the eagle nebula was discovered by Jean-Philippe de Cheseaux in 1745–46 , The Eagle Nebula is about 6,500 light-years from Earth. In 2014, it was observed once again, this time with other observatories delving deeper into the region, with researchers providing new details about the region, which is filled with practically hundreds of millions of stars. The Pillar of Creation is once again seen, this time by the James Webb Space Telescope of the "Pillar of Creation" region within the Eagle Nebula, within dense clouds of gas and dust in this lush, highly detailed landscape  New stars are being formed. The three-dimensional pillars of the Eagle Nebula look like majestic rock formations, but are far more permeable, and are composed of cooler interstellar gas and dust, which sometimes appear semi-transparent in near-infrare...

Two newborn stars are spewing radiation and particles to form bubbles.

  Clouds make many types of shapes in the sky, which attracts us, and in some way in the universe also clouds of gas, dust make many types of shapes, this shape tells a lot about stars. In the darkest corner of the constellation Circinus is the Black Widow Nebula, whose two stars are producing intense radiation and very strong particle winds,causing both radiation and stellar winds to blow dust outward from the star, forming a bubble, and the gas and dust in this bubble have taken on the shape of a spider,which astronomers know as the black widow spider. Astronomers suspect, as in the case of the Lac Widow Nebula, that the Lac Widow Nebula is a large cloud of gas and dust that condenses to form several clusters of massive star formation, and that these massive stars may be formed. The combined winds probably blew the bubble in the direction of least resistance, forming a double-bubble, For decades, the black widow spider has remained largely invisible, but the dust-piercing, infrar...

Rings of dust, formed from stellar winds, as seen by the Webb Telescope.

When two stars come close together, their stellar winds (streams of gas they blow into space) combine, which compress the gas, forming dust, and rings of dust mark the loop time. The James Webb Space Telescope captured an image of the Wolf-Rayet 140, located 5,000 light-years from Earth, The rare type of star in this image is locked in a celestial dance by its companion, showing 17 concentric dust rings emanating from a pair of stars, the image reveals a remarkable cosmic view. This image shows how sensitive the Webb telescope is, says NOIRLab astronomer Ryan Lau, because before, we could only see two dust rings using ground-based telescopes, But webb has shown us at least 17 rings. In addition to Webb's overall sensitivity, the Mid-Infrared Instrument (MIRI) is uniquely qualified to study dust rings, say Lau and his colleague Gole, Because webb's instruments detect infrared light, which cannot be seen by the human eye, it is a range of wavelengths invisible to the human eye.

Researchers have discovered a "super-Earth, in which there is a possibility of life.

  The constellation of Eridanus, 105 light-years away from the Solar System, contains a high proper speed red dwarf star known as LP 890-9, which has a mass of 12% and 15% of the Sun's radius, and a temperature At 2,871 K (2,598 °C; 4,708 °F), it is the second coldest star to host a planetary system after TRAPPIST-1.  Researchers discovered LP 890-9b using the Transiting Exoplanet Survey Satellite (TESS), and LP 890-9c was discovered during follow-up observations of LP 890-9b, Both these planets fall in the super-Earth category. The researchers found that the two planets are comparatively quiet, and are orbiting the red-dwarf star, LP 890-9, an inner planet that is about 30% larger than Earth, With an estimated temperature of 253 °F (123 °C), it is too hot for human life, but LP 890-9c is an outer planet, it is colder at an estimated 30 Fahrenheit (minus 1.1 Celsius), and remains close to its star. LP 890-9c orbits within the habitable zone of its star, LP 890-9c is a favorabl...
