Most Memorable Space Photographs Of Year 2015. Photographs taken by NASA On Different Days Across Whole Year.
In 2015 the world saw many changes and most memorable moments in history from cricket world cup to Nepal earthquake. Every field witnessed some most interesting and memorable moments.Same thing Astronomy witness as NASA took few pictures of giant stars blasting and fading away into gases. Below are top 6 pictures of Astronomy in 2015.Lets take a round up and see most interesting pictures of stars who are million light years away from us.Taken by Hubble telescope.
1. WOLF RAYET STAR
Star WR-124 which is surrounded by nebula m-167. Nebula m-167 is no more than 10,000 years old.Which is baby in astronomical terms. Still it makes a beautiful sight with amazing flare in it.
Most burning stars in our universe might be the most shortest lived.Wolf Rayet in its last stages bright up and gets hot to an extreme level with million times more than our lovely sun.It is located in constellation saggitarius. This picture was taken by Hubble space telescope.Dynamics of this star are different than our sun its mass is around nine times more and radius ten times of our sun.They burn more brighter as they get old.As they run out of elements there heat and radiation increases which result in powerful winds which causes loss of mass.When there core collapse they explode out in form of supernova.Well this star have still some life left.
2. VEIL NEBULA
Known as Veil Nebula is a debris one of the best supernova remnants we know till now.This picture with details was released by NASA on 24sep 2015.It shows a small section of remains of star around 8000 years ago.The entire nebula is expanded over 110 light years covering the size of around six full moons.It is located 2100 light years ago from Earth in constellation cygnus,the swan.It shows gaseous remains of star which was 20 times more bigger than our sun.Nebula is along the large bubble of less dense gad which was blown away prior to its self detonation.
3. MESSIER 96
It's a spiral galaxy located only 35 million light years away from us.Its dynamics are similar to milky way galaxy it have same mass and size.It was first discovered in 1781 by Pierre Mechain. The galaxy looks like a giant maelstrom of glowing gas.Gases and dust around it is unevenly spread throughout of its spiral arms and even with its core not at galactic center. This could have been because of the gravitational pull by other galaxies nearby.This picture was taken by my favorite Hubble telescope and was released by NASA on sep 4 2015.
4. PLANETARY NEBULA
Generally known as planetary Nebula and Astronomically it is known as pk329-02.2. Some times it is often referred as Menzel 2 named after astronomer. It is located in constellation of Norma in southern sky.When stars around sun comes to their last stages they shed their outer layers into space which looks like glowing gaseous clouds.In this picture star causes this blue gas with two stars in center.It was discovered that stars at upper right corner is the central star while the second one is physical companion of star.In next few thousand years ago these gases will fade away in darkness of universe.It is its good bye sign before it reaches in its last moment of life and becomes white dwarf.It was last updated by NASA on oct 9 2015.
5. Celestial Fireworks
It is picture of young stars flaring to life in blue color while nebula in between them.It was released to mark 25th anniversary of Hubble in space.It is basically a cluster which is expands over 6 and 13 light years.Giant star cluster is approx 2 million years old and have some of the galaxies hottest and brightest even massive stars.The red little tiny dots in landscape represent new born stars still wrapped up in gas and dust cocoons and are only 1 or 2 million years old.Star cluster which is in center of image shows red shades which represent are hydrogen and bluish green region is predominantly oxygen.
6. A LITTLE GEM
Well NASA call it a little gem it is basically a planetary nebula which is called NGC 6818 in terms of astronomy.It resides far from us in constellation of Sagittarius which is around 6000 light years from us.Its body spans over half light year across.When stars like sun enters in their last phase they shed their outer layers into space which causes glowing gaseous clouds.It can have very complex shapes as well.It shows a bright and enclosed central bubble which is surrounded by larger diffuse cloud.Well scientists of NASA believe that stellar winds from central star propels is the out flowing material which sculpts shape of this star.Fast winds moves into slower clouds it created bright blowout at outer layer of bubble. It was first taken in 1997 but now it was released again.
These were most interesting or memorable pictures of 2015 taken by Hubble telescope and year 2015 marked Hubble's 25th anniversary. Hubble will last around 2030 to 2040 in space with its successor to launch in 2018.Hope you guys will like my article let me know by commenting below/
