The amazing technological advancements in recent decades have allowed NASA to send more and more spacecraft to faraway places, enabling Earthlings to explore everything from planets and stars to entire galaxies and even black holes.Letting the International Space Station orbit our own planet also allowsUnder unique conditionsconductScientific research, Carried out by the first generation of humans who lived and worked in space.
To celebrate another extraordinary year of space exploration, we have selected some of the most eye-catching images released by NASA in the past 12 months. enjoy!
This is the beautiful spiral galaxy NGC 691, located in the constellation Aries about 120 million light-years from the Earth, captured by the Hubble Space Telescope. NGC 691 was discovered by astronomer William Herschel in 1786, and its diameter is calculated to be 130,000 light years.
Aurora over the southern sky
The beautiful aurora above the Earth, captured from the International Space Station (ISS), orbits 274 miles above the South Indian Ocean between Australia and Antarctica.
Just this year, NASA’sThe Perseverance rover arrived in spectacular fashionMars. Soon after landing, Perseverance began to explore the red planet and also found time to take a few selfies. The photo you see here was created using 62 separate lenses that can remove the selfie stick (or more accurately a robotic arm).This is how the image is created.
The stunning Flame Nebula, also known as the less noticeable name NGC 2024, is located in the constellation Orion about 1,400 light years from Earth. This image taken by Hubble shows the dark, dusty center of the nebula where the star cluster is located, although it is mostly hidden from view.
International Space Station
During a rare orbital outpost flight, an astronaut looks out from SpaceX’s Crew Dragon spacecraft, and the International Space Station stands out in the dark of space.
This incredible image shows two large rotating storms on Jupiter, captured by the Juno camera on NASA’s Juno spacecraft during one of its multiple passes.
NASA noticed bright “pop-up” clouds above the lower storm. Clouds may appear small, but they are actually large, usually about 30 miles (48 kilometers) wide.
Consequences of the cosmic explosion
Another wonderful Hubble picture, this picture shows the cosmic gas belt left by the explosion of a huge star called a supernova. The devastating event occurred in a portion of the Large Magellanic Cloud about 158,000 light-years from Earth.
Tropical Storm Wanda
Closer to home, here we saw about 260 miles from the earth in early NovemberSpace station cupola moduleThe captured tropical storm Wanda. In the foreground, you can see one of the two cymbal-shaped UltraFlex solar arrays, part of Northrop Grumman’s Cygnus spacecraft.
Frosted sand dunes on Mars
Frost on Mars? Yes, it is one thing, as evidenced by this extraordinary image taken by NASA’s Mars Reconnaissance Orbiter from an altitude of approximately 196 miles (315 kilometers). Frost is on the sand dunes in the crater of the high latitudes of the northern plains of this red planet.
Jupiter’s Great Red Spot
This photo taken by Juno from 8,600 miles (13,840 kilometers) above Jupiter’s cloud top gives us a wonderful understanding of one of the planet’s most famous features, the Great Red Spot.
NASA data shows that this huge vortex extends to Jupiter’s atmosphere much deeper than originally thought, reaching about 300 miles (500 kilometers) below the cloud top.
“This surprising discovery shows that the Great Red Spot and other vortices have fallen below the depth at which sunlight warms the atmosphere, providing new clues to the inner workings of this planet’s beautiful and intense atmosphere.”
The original image was taken in 2017, but citizen scientist Andrea Luck recently processed it based on the original JunoCam data to create the reproduction shown here.
SpaceX’s cargo dragon
Another amazing work from the space station, this photo shows a cool view of the SpaceX cargo dragon, below the earth, when the spacecraft approaches the International Space Station, its nose cone is raised in preparation for docking.
This extraordinary Hubble image shows a small part of the Veil Nebula, showing its delicate threads and filaments of ionized gas. The Veil Nebula is located in the constellation Cygnus (also known as the Swan and Northern Cross), about 2,100 light years from Earth.
According to NASA: “The Veil Nebula is the visible part of the nearby Cygnus ring. This is the remnant of a supernova formed by the death of a massive star about 10,000 years ago. The star is 20 times the mass of the sun and it lives fast. , Died very young, and ended its life in a catastrophic release of energy.”
This image taken by Hubble (artificially colored by astronomers to enhance the analysis details) shows the decomposition of the solid nucleus of Comet Atlas. Analysis of this image and another similar image has determined as many as 30 independent fragments. When Hubble recorded the dramatic appearance of the comet, the comet was approximately 91 million miles from Earth. Astronomers believe it may come from a larger comet that was swayed by the sun 5,000 years ago.
French astronaut Thomas Pesquet was connected to an articulated portable foot restraint at the end of Canadaarm2’s robotic arm during a spacewalk to be on the International Space StationInstall the newly launched solar arrayTo upgrade the power supply of the facility.
Ganymede, the moon of Jupiter and the largest moon in our solar system, is in the image taken by Juno as it flew over the icy moon. NASA stated that at the time of its closest approach, the spacecraft was 645 miles (1,038 kilometers) from its surface, “it is closer to Jupiter’s largest satellite than any other spacecraft in the past two decades.”
Finally, here we saw CW Leonis, a dying star, engulfed by orange-red “cobwebs”, which are actually dust clouds made of coal ash carbon.
CW Leonis is 400 light-years away from Earth and is the closest carbon star to us, providing scientists with the best opportunity to study celestial bodies of this nature.
You will definitely notice that Hubble has been doing some extraordinary work since it was deployed more than 30 years ago. Although it will continue to explore the universe for a while, soon more powerful James will join astronomers to believe in the Webb Space Telescope.Will usher in a new era of space discovery.
