For 25 years now, the Hubble Space Telescope (and many other satellites) has stimulated us with numerous jaw dropping images of space—stretching from the Great Nebula of Orion, to the Whirlpool Galaxy. They all look so huge and comprehensive, you can nearly imagine yourself moving through space, looking directly at them from up close—yet even the closest among them are unfathomably far away (the closest planet is nearly 162 million miles/261 million kilometers from sun, while the closest star is over 4 light-years distant). In a recent video, the Russian Space Agency (Roscosmos, to be exact) visualizes how our sky may look if some of these marvels were in nearer proximity to Earth. Watch the video below:
Hubble Space Telescope marks 25th anniversary in orbit this week. So, There are some best images taken by Hubble Space Telescope during its 25 years journey. These Images are 100% real and contains no CGI
Hubble has traveled 3.4 billion miles, circling Earth nearly 137,000 times and making more than 1.2 million observations of more than 38,000 celestial objects, according to the Space Telescope Science Institute in Baltimore. The most distant objects spotted by Hubble — primitive galaxies — are some 13 billion light-years away and date to within 400 million or so years of the universe’s origin, known as the Big Bang.
Hubble provides an average of 829 gigabytes of archival data every month, according to the institute. Altogether, Hubble has produced more than 100 terabytes of data.
Some of the images have description about it. if anyone wants to read image description just click that image. and Enjoy……

This newly released Hubble image shows Messier 22, the brightest globular cluster visible from the northern hemisphere.
A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers.
Messier 22 is located in the constellation Sagittarius, approximately 10,400 light-years away.
It was the first globular cluster to be discovered. German astronomer Johann Abraham Ihle found it on August 26, 1665, while observing Saturn.
The cluster, also known as M22 or NGC 6656, has a diameter of about 70 light-years and half a million solar masses.
According to astronomers, Messier 22 orbits the galactic center once every 200 million years.
The cluster is an easy object for the naked eye to see. Despite its relative proximity to us, the light from the cluster’s stars is not as bright as it should be as it is dimmed by dust and gas located between us and Messier 22.
As they are leftovers from the early Universe, globular clusters are popular study objects for astronomers.
Messier 22 has fascinating additional features: six planet-sized objects that are not orbiting a star have been detected in the cluster; it seems to host two black holes.
The cluster is one of only three ever found to host a planetary nebula – a short-lived gaseous shells ejected by massive stars at the ends of their lives.

In 1995, the Hubble Space Telescope captured what would become one of history’s most enduring images of the universe: The Eagle Nebula’s Pillars of Creation. Now, 20 years later, Hubble has released a collection of brand new, high-definition shots of the iconic formation.
If you thought the universe was hauntingly beautiful before, wait until you see these.

Comprised of three towers of gas, dust and space matter, structures like this are not altogether uncommon in star-forming regions. But as the Hubble website notes, the Pillars of Creation are some of the most photogenic and mesmerizing examples ever seen.
“The Hubble image of the pillars taken in 1995 is so popular that it has appeared in film and television, on tee-shirts and pillows, and even on postage stamps,” HubbleSite writes.
The telescope used the Wide Field Camera 3 to capture the stunning new images. It sees near-infrared light, visible like and near-ultraviolet radiation, and also has higher resolution and a bigger field of view than the camera that came before it.
This time, Hubble also captured an image taken in infra-red light, which “penetrates much of the obscuring dust and gas and unveils a more unfamiliar view of the pillars,” according to the website. “Here newborn stars, hidden in the visible-light view, can be seen forming within the pillars themselves.”
Not everything is happy-go-lucky in Pillars of Creation-land, however. Despite their name, the new shots indicate that the pillars are also being worn down by the very stars they are helping to incubate. “The dust and gas in these pillars is seared by intense radiation from the young stars forming within them, and eroded by strong winds from massive nearby stars,” HubbleSite explains.
Arizona State University’s Paul Scowen, who helped lead Hubble’s first deep dive into the Eagle Nebula, stressed just how incredible our sightings of the Pillars are. “I’m impressed by how transitory these structures are,” he said in a press release. “We have caught these pillars at a very unique and short-lived moment in their evolution.”
Interestingly, environments like the Eagle Nebula and other star-forming regions were instrumental in our own solar system’s development. “What that means is when you look at the environment of the Eagle Nebula or other star-forming regions, you’re looking at exactly the kind of nascent environment that our Sun formed in,” Scowen said.
