Jupiter Spectacular Image taken from James Webb

The James Webb space telescope took the picture of the Jupiter in July.
Astronomers have described as incredible Picture of the Jupiter ever because images show auroras, giant storms, moons and rings surrounding Jupiter.
The Infrared images were artificially coloured astronomer Imke de pater of the university of California who played an important role in this project.
JWST is an International mission led by the Nasa along with ESA and Canadian space agent .
Nasa Said that view of Jupiter created from composite of several pictures from the telescope , Auroras extended to high altitudes above the northern and southern poles of Jupiter.
The Great Red Spot a famous storm which is so big (16350 km), appeared white because of reflected of sunlight.
The JWST was launched in December 2021 and it currently placed about 1.6 million km from Earth.

OSIRIS-REx HomeComing

OSIRIS-Rex

Osiris- Rex satellite is returning back to earth from Benu Asteroid .

Osiris -Rex is the mission to collect the sample from the Asteriod Benu, this mission launched in September 8 2016 from Florida.

In August 2018 it has approached Benu and following month we can see the clear picture of Benu. After serious of flights around the Benu, scientist spotted the best place to take the sample and in October 2020 satellite touch the Benu for the Brief moment and collected the samples .

After the collection of sample from Benu, satellite moved to safe distance and sample was safely sealed. The mass of collection sample might be between 60g to 2000g.

On October 22 2020 Osiris-Rex Departure from benu orbit and continued its journey to Earth.

Rex will returned to earth by Sep 24, 2023. When satellite reached the earth orbit it will release it capsule and that will safely fall into the Utah desert.

Benu

Benu Discovered in 1999 and its radius is 262 m. Benu is confirmed potentially hazardous asteroid and we have chance of 0.037 hitting the earth between 2175 to 2199.

Hubble 31st Birthday Gift to US

AG Carinae

Hubble Completed is 31 years of journey in Space yesterday – April 24.

During this Day Nasa Goddard YouTube Channel Published the Video about Image taken by Hubble on its 31year of completion in space.

Hubble captured the Wonderful Image of Exploding Star AG Carinae which is 70 times massive than our Sun.

Its Shinning Brilliance Light is equal to the million of our star brightness.

This Sun was Exploded 10000 years Ago so we can see the Halo of Gas and Dust Around the Star center mass.

This Nebulae Covers about 5 Light Years of distance from the center of its Sun .

Hubble Once Show us how the Stars are so Powerful and breath taking to watch. Every Elements in universe except hydrogen and helium are formed by sun and during its explosion.

Hubble Deep Field Image is still one of wonderful image taken by Hubble this day. This image is consists of 10 days of exposure of Hubble in particular direction in space from December 18 and 28, 1995. This image shows how big was our universe every dots in that Picture is a Galaxy. Using this image we also find the old light of our Universe which is less than billion years from birth of our Universe.

The Great Conjunction

The Great Conjunction is name given to the two Mega Planets in our Solar System come together to form large star in the night sky. These two Biggest Planets are namely the Jupiter (largest planet) and Saturn (second largest planet).

Today 21 December the we can the see this event in the night sky . We can see the planets at southwestern sky. We can see this event without any eye protection.

Dr. James O’Donoghue Planetary Scientist at Jaxa has tweeted the timing for great conjunction.

  • Los Angeles: 09:43
  • New York: 12:43
  • Rio de Janeiro: 14:43
  • London/UTC: 17:43
  • Paris/CET: 18:43
  • Istanbul: 20:43
  • Dubai: 21:43
  • New Delhi: 23:13
  • Tokyo: 02:43 (22 Dec)
  • Sydney: 04:43 (22 Dec)
    • (+/- minutes; )

This Post picture is taken from Nasa official Solar System webpage. This is the static image but in the Nasa official Planets Page we can we see the live tracking of all the planets in our Solar System . This animation will tech us how our Planets are moving in our Solar System. If we search for particular planet we see the closer look of the planet and we can see the solar system from that planet point of view.

The official Nasa Solar System : https://solarsystem.nasa.gov/

These two planets align every 20 years , but this the closest alignment since July 16, 1623 , 397 ago.

You can track the planets with your phone using the Sky Map . This App was created by Google: https://play.google.com/store/apps/details?id=com.google.android.stardroid&hl=en_IN&gl=US

Our Sun next Solar Cycle

Our Sun next solar cycle started on Sep2020.


Solar cycle happen every 11 years. This solar cycle calculated based on minimum and maximum solar activity. During this period the sun flip the magnetic field from north to south so these leads to heavy solar activity and when sun reaches it peak activity we can see many Sun spots.


Sunspots are usually black in color in visible light, but when we see the Sun in ultra violet wavelength we can see the intensive magnetic field activity .


Why we need to monitor the Solar cycle?

During the Sun’s peak active period large amount of coronal mass ejection will happen , so during this time it will directly affect the earth and heats up the earth atmosphere that will cause damage to electric transmission , pipelines ,communication towers and satellites. Also this huge radiation affect the astronauts in space station.


So Continuous Monitoring will help us to understand pattern of the peak solar activity , Using that we can prevent the electronic equipment by turning off the device during the peak solar period. Also we warn the astronaut not to do the space walk during that period.

Usually peak solar activity happens in middle of the solar cycle. Last one happen at 2012.


This information Updated by Nasa on Sep18 and followed by they Published the video on YouTube. Please check the following link to view discussion between the solar experts:


note: Last major corona mass ejection happen at 2012 and we detected this event only after 9 days from the event.

Ligo and Virgo detected largest black hole merger

Computer simulation model
This merger approximately happen at 5 gigaparsecs (1 gigaparsecs = 19 trillion miles) from our planet. This caused the huge gravitational waves in cosmic space and this gravitational waves are detected by two detector Ligo and Virgo . According to research this event is caused by merger of two intermediate black hole and their mass are between the 100 to 1000 times of of our SUN. This was named as GW190521 the name given based on the gravitational waves detection on May 21 ,2019.
info: gravitational waves means massive ripple effect in space time caused by violent explosion like supernova explosion or merger of black holes or merger of neutron stars.
Ligo : This is the 4km long detector in United states .
Virgo: This is the 3km long detector in Italy.
These two detector used to listen the gravitational waves that passes the earth.
According to Ligo this merger creates the new mega black hole which is 142 times massive than our sun and also released energy which massive as 8 times of our sun, this energy spread across the space in the form of gravitational waves. This event is happen in just 1/10 of second.

Perseid Meteor Shower

Perseid Meteor Shower usually occurs from July 14 to August 24 in North Skies Every Year. This year August 12 and 13 are calculated as peak days to see the Meteor Showers. During this Peak time we can see 100 meteor per hour. In India we can see the Meteor shower from 11.30pm to 5.30am .
If your are in the different country please checkout the below link to select your city name and check the angle to view the meteor shower.

How this Meteor shower occurs?
These meteors are the remaining Pieces of Comet 109P/Swift-Tuttle. This comet spin around the sun every 133 year last seen on 1992. Comets, when they approaching the sun some of its surface rock will left as debris throughout the comet path . Every year Earth passes through this Debris leads to Meteor Shower.
