IMAGES CAPTURE BY JAMES WEBB SPACE TELESCOPE

As we all know that on 25 December, 2022 New Space telescope has had be launch known as James Webb space telescope in replacement of Hubble space telescope.

It had said some images of different galaxies and other some of the selected image released by NASA on 11 July 2022 the name of these images as follows:

1) SMACS 0723

2) WASP – 96B

3) SOUTHERN RING

4) STEPHEN’S QUINTET

5) CARINA NEBULA

=> Some detail information about these images:

• SMACS 0723:-


This is the first image that released by James Webb space telescope of the deepest sharpest inferred image of distance universe ever produce.

This image is of galaxy cluster SMACS 0723 and other thousands of galaxies. The galaxy cluster SMACS 0723 appears here it would have exist 4.6 billion year ago. This is deep field that show the phenomena known as gravitational Lensing in action to study and pressing galaxy is back to the beginning of cosmic time.

• WASP-96B:-


Webb’s observe hot and puffy planet outside our solar system that Rebel the clear signature of water it is also known as exoplanet. It is a composition of gas locate just 1150 light year away and the temperature of the exoplanet to be about 1350°C. It also have cloud that previous studies of this planet did not detected.

• Southern Ring:-


This planetary nebula and expanding cloud of gas that surrounded a dying star. It lies approx 2000 light year away and it is visible to observe living in southern hemisphere, as it can be found within the constellations of Vela.

• Stephen’s QUINTET:-


This is a group of galaxies known as Stephen Quintet. It is located 290 million light year away in the constellation Pegasus, in the same patch of sky as the famous asterism known as the great square of Pegasus.

=> Stephen Quintet show different lights

Red light indicate star forming region, distance early galaxies and galaxies covered in dense cosmic dust.

Blue light show stars or stars cluster without dust while more diffuses area of blue reveal dust containing large amount of hydrocarbon molecules.

Green and yellow light represent more distant, earlier galaxies that are also rich in hydrocarbon.

• Carina Nebula:-


It is a type of glowing cosmic cloud found about 7600 light year away. Telescope looks at the ‘Cosmic Cliffs’ in the Carina Nebula unveils the earliest, rapid phases of star formation that were previously hidden.

It is the edge of giant gaseous cavity with in NGC 3324, and the tallest “peak” in this image are about 7 light years high.

=> How Hubble space telescope hai is different from James Webb space telescope

• Webb will primarily look at the universe in the infrared while how are you studied it primerly at optical and ultraviolet wavelength.


• Web has also much bigger mirror than Hubble. Webb have 6.5 meter diameter and Hubble have 2.4 meter diameter.


• The Hubble space telescope orbits around the Earth at an altitude of approximately 570km above it. Webb space telescope will not actually orbits the Earth instead it will sit at the Earth-Sun L2 lagrange point. Which is 1.5 million km away.


• The collecting area of Hubble is 4.5 m2 and 6.25 time more collecting area of Webb.

• Hubble telescope don’t have any sunshield whereas James Webb have sunshield and it have area equal to a tennis court that like a parasol providing shade.


Using the above background information, (and additional sources of information from the dictionary).

About James Webb Space Telescope

JAMES WEBB SPACE TELESCOPE  JAMES WEBB SPACE TELESCOPE Firstly we need to know about the space telescope. It is a telescope which is placed in outer space and used to observe astronomical objects. And also used to study different types of light phenomenon like Aurora lights and to study hottest and most explosive object. Currently, NASA had launched a space telescope named as JAMES WEBB SPACE TELESCOPE [JWST] . It was made by international collaboration among NASA, the European Space Agency, and the Canadian Space Agency. It works as a replacement of Hubble Space Telescope. JWST was launched on 25 December 2021 on Arian Flight VA256. Firstly it was named as Next Generation Space Telescope and after some time name change to James Webb Space Telescope. There are some properties of JWST are Mass- 6161.4kg , Dimensions- 20.197m×14.162m , Power- 2KW. It operates in a Halo orbit, circling around a point in space known as the Sun-Earth Lagrange Point, approx 1500000km beyond Earth orbit a...

Lifecycle of a star : Birth to Death

STARS AND PLANETS  Star A star is a luminous and biggest object in the universe that emit light naturally. Sun is also a star. The study of birth , life and death of a stars is called stellar evolution. First stage in the birth of star is called protostar and the death of star is called supernova .  FORMATION OF A STAR BY CLOUD OF DUST How stars are formed ? Stars are made by cloud of gases and dust that scattered throughout the galaxies. The cloud of dust is called the orion nebula . As gravitational force of attraction applied on cloud they collapses and when cloud collapse the material at the center get heat up so that all stars and planet have high temperature at core. A star build by continuous process of gravitational pull cloud collapse to make its size bigger. The size of star (or mass of a star) reaches from  15 to 130 solar masses . At center the temperature gets extremely high, it tigger the fusion reaction. All the material that has fallen in then evolves int...

AURORA: THE LIGHT OF POLES

Space view of Aurora Lights  Firstly, we need to know about the aurora. Auroras are the light which is produced naturally by collision of charge particles with gasses molecules present in the atmosphere. Predominantly sun in high latitude region like arctic and Antarctic. This light produces always at poles because magnetic field of earth is stronger on the poles and also the density of magnetic field lines is high there. Thus, a large number of charge particles found at the poles. The charge particles collide with the gasses to making them excited that cause  coloured visible light. When the charge particle collides with oxygen molecules then green light is emitted mostly but sometimes it produce red light and when collides with nitrogen molecules then more pink , orange or red colours emitted. Different types of Aurora Light seen on different places  These light appearing near the North Pole and South Pole. Scientist name these light as at North Pole light called “ A...
