Unveiling the Center of Our Milky Way Galaxy

We captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.

Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.

The new view was made by the world’s largest airborne telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA.

Sixty Years of Exploration, Innovation, and Discovery!

Exactly sixty years ago today, we opened our doors for the first time. And since then, we have opened up a universe of discovery and innovation. 

There are so many achievements to celebrate from the past six decades, there’s no way we can go through all of them. If you want to dive deeper into our history of exploration, check out NASA: 60 Years and Counting. 

In the meantime, take a moonwalk down memory lane with us while we remember a few of our most important accomplishments from the past sixty years!

In 1958, President Eisenhower signed the National Aeronautics and Space Act, which effectively created our agency. We officially opened for business on October 1. 

To learn more about the start of our space program, watch our video: How It All Began. 

Alongside the U.S. Air Force, we implemented the X-15 hypersonic aircraft during the 1950s and 1960s to improve aircraft and spacecraft. 

The X-15 is capable of speeds exceeding Mach 6 (4,500 mph) at altitudes of 67 miles, reaching the very edge of space. 

Dubbed the “finest and most productive research aircraft ever seen,” the X-15 was officially retired on October 24, 1968. The information collected by the X-15 contributed to the development of the Mercury, Gemini, Apollo, and Space Shuttle programs. 

To learn more about how we have revolutionized aeronautics, watch our Leading Edge of Flight video. 

On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first humans to walk on the moon. The crew of Apollo 11 had the distinction of completing the first return of soil and rock samples from beyond Earth. 

Astronaut Gene Cernan, during Apollo 17, was the last person to have walked on the surface of the moon. (For now!)

The Lunar Roving Vehicle was a battery-powered rover that the astronauts used during the last three Apollo missions. 

To learn more about other types of technology that we have either invented or improved, watch our video: Trailblazing Technology.

Our long-term Earth-observing satellite program began on July 23, 1972 with the launch of Landsat 1, the first in a long series (Landsat 9 is expected to launch in 2020!) We work directly with the U.S. Geological Survey to use Landsat to monitor and manage resources such as food, water, and forests. 

Landsat data is one of many tools that help us observe in immense detail how our planet is changing. From algae blooms to melting glaciers to hurricane flooding, Landsat is there to help us understand our own planet better. 

Off the Earth, for the Earth.

To learn more about how we contribute to the Earth sciences, watch our video: Home, Sweet Home. 

Space Transportation System-1, or STS-1, was the first orbital spaceflight of our Space Shuttle program. 

The first orbiter, Columbia, launched on April 12, 1981. Over the next thirty years, Challenger, Discovery, Atlantis, and Endeavour would be added to the space shuttle fleet. 

Together, they flew 135 missions and carried 355 people into space using the first reusable spacecraft.

On January 16, 1978, we selected a class of 35 new astronauts--including the first women and African-American astronauts. 

And on June 18, 1983, Sally Ride became the first American woman to enter space on board Challenger for STS-7. 

To learn more about our astronauts, then and now, watch our Humans in Space video.

Everybody loves Hubble! The Hubble Space Telescope was launched into orbit on April 24, 1990, and has been blowing our minds ever since. 

Hubble has not only captured stunning views of our distant stars and galaxies, but has also been there for once-in-a-lifetime cosmic events. For example, on January 6, 2010, Hubble captured what appeared to be a head-on collision between two asteroids--something no one has ever seen before.

In this image, Hubble captures the Carina Nebula illuminating a three-light-year tall pillar of gas and dust. 

To learn more about how we have contributed to our understanding of the solar system and beyond, watch our video: What’s Out There?

Cooperation to build the International Space Station began in 1993 between the United States, Russia, Japan, and Canada. 

The dream was fully realized on November 2, 2000, when Expedition 1 crew members boarded the station, signifying humanity’s permanent presence in space!

Although the orbiting lab was only a couple of modules then, it has grown tremendously since then! 

To learn more about what’s happening on the orbiting outpost today, visit the Space Station page.

We have satellites in the sky, humans in orbit, and rovers on Mars. Very soon, we will be returning humankind to the Moon, and using it as a platform to travel to Mars and beyond.

And most importantly, we bring the universe to you.

The Great Aviation Transformation Begins

On this National Aviation Day, we’re going “X.” 

Today we celebrate the birthday of one of America’s original U.S. aviation pioneers — Orville Wright. But this year we also celebrate the pioneers of right now — the women and men of NASA who are changing the face of aviation by going “X.” We’re starting the design and build of a series of piloted experimental aircraft – X-planes – for the final proof that new advanced tech and revolutionary shapes will give us faster, quieter, cleaner ways to get from here to there.

So, what is an X-plane?

Since the early days of aviation, X-planes have been used to demonstrate new technologies in their native environment – flying through the air aboard an aircraft that’s shaped differently from the tube-and-wing of today. X-planes are the final step after ground tests. They provide valuable data that can lead to changes in regulation, design, operations, and options for travel. Two of the most famous historical X-planes are the Bell X-1 and the X-15.

Why can’t I fly supersonic now, say from New York to Seattle?

Because of the loud, jarring sonic boom. Commercial supersonic flight over land and, therefore over communities, is currently prohibited. Our supersonic X-plane will fly “quiet”; there’ll still be a sonic boom but it’ll sound more like a soft “thump.”  The Low Boom Flight Demonstration X-plane, scheduled for first flight in 2021 and to begin community overflight testing in 2022, will provide the technical and human response data to federal and international regulators so they can consider lifting the ban. If that happens, someday commercial supersonic passenger flights between U.S. coasts would be less than three hours.

This is a preliminary design of the Low Boom Flight Demonstration X-plane. Its shape is carefully tailored to prevent the formation of a loud sonic boom.

Will I ever be able to carry on a conversation when a plane flies overhead?

Yes. Our next X-plane will be one that flies at regular speed, but has advanced design technologies and a nontraditional shape that drop perceived noise level by more than half. It will also reduce fuel consumption by 60-80 percent, and cut emissions by more than 80 percent. Design of this piloted X-plane is expected to begin around 2020.

This possible X-plane design is a blended wing body, which reduces drag and increases lift, and also reduces noise because the engines are placed above the fuselage.

Will I ever fly on an airplane powered like my Prius?

Probably. All- or hybrid-electric aircraft that can carry 12 – 120 passengers are becoming more likely. For a larger aircraft and possible future X-plane, NASA is studying how to use electric power generated by the engines to drive a large fan in a tail-cone and get additional thrust for takeoff and reduce fuel use.

This possible future subsonic X-plane would use electricity to power a large fan in the tail-cone, providing extra thrust at takeoff.

We – along with our government, industry and academic partners – have begun the great aviation transformation. And you’ll witness every important moment of our X-plane stories, here and on every #NationalAviationDay.

Why do we explore? Simply put, it is part of who we are, and it is something we have done throughout our history. In "We Are the Explorers," we take a look at that tradition of reaching for things just beyond our grasp and how it is helping us lay the foundation for our greatest journeys ahead. So what are we doing to enable exploration? We’re building the Orion spacecraft is built to take humans farther than they’ve ever gone before. Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel, and provide safe re-entry from deep space return velocities. Orion will launch on NASA’s new heavy-lift rocket, the Space Launch System.

Also underway, is Astronaut Scott Kelly’s Year In Space. Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world more than 220 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day conducting research about how the body adapts and changes to living in space for a long duration.

Hubble Space Telescope

You’ve probably heard of our Hubble Space Telescope, but have you had the chance to actually take a look at the amazing images it has captured for us over the years? Since Hubble launched in April 1990,  it has made more than 1.2 million observations, some to locations more than 13.4 billion light years from Earth!

Hubble can see astronomical objects with an angular size of 0.05 arc seconds, which is like seeing a pair of fireflies in Tokyo from your home in Maryland…yea, that’s pretty far! This accuracy allows us to see images like this one of Little Gem Nebula, roughly 6,000 light-years away from us.

Images from Hubble are regularly released to the public, and are some of the most breathtaking views in the Universe. Images like this one of Lagoon Nebula, in the constellation of Sagittarius, not only make for amazing desktop screen-savers, but provide us with valuable scientific information about distant stars and galaxies, as well as the planets in our solar system.

We recently celebrated Hubble’s 25th Anniversary, and look forward to many more years of discovery and captivating images.

A Dusty Fingerprint in Space

A new image from NASA's James Webb Space Telescope reveals a remarkable cosmic sight: at least 17 concentric dust rings emanating from a pair of stars. Just 5,300 light-years from Earth, the star duo are collectively known as Wolf-Rayet 140. Each ring was created when the two stars came close together and their stellar winds (streams of gas they blow into space) collided so forcefully that some of the gas was compressed into dust. The stars' orbits bring them together about once every eight years, and forms a half-shell of dust that looks like a ring from our perspective. Like a cosmic fingerprint, the 17 rings reveal more than a century of stellar interactions—and the "fingerprint" belonging to Wolf-Rayet 140 may be equally unique. Other Wolf-Rayet stars produce dust, but no other pair are known to produce rings quite like Wolf-Rayet 140.

Of course Saturn brought its ring light.

On June 25, 2023, our James Webb Space Telescope made its first near-infrared observations of Saturn. The planet itself appears extremely dark at this infrared wavelength, since methane gas absorbs almost all the sunlight falling on the atmosphere. The icy rings, however, stay relatively bright, leading to Saturn’s unusual appearance in this image.

This new image of Saturn clearly shows details within the planet’s ring system, several of the planet’s moons (Dione, Enceladus, and Tethys), and even Saturn’s atmosphere in surprising and unexpected detail.

These observations from Webb are just a hint at what this observatory will add to Saturn’s story in the coming years as the science team delves deep into the data to prepare peer-reviewed results.

In recent years of tracking weather activity and the like, have there been more 'anomolies' that have stuck out more than others? (I.E hurricanes, typhoons or cyclones that start out as small storms then become hurricane 4-5 storms in a matter of days-weeks) I think what you guys are doing is awesome and keep up the good work ~TKL

What are the moments when you think to yourself "yes. THIS is why I love my job"..? ✨

What are Perseid Meteors, and why should you be excited for them this year? Let us tell you!

The Perseid meteor shower is caused by debris from Comet Swift-Tuttle as it swings through the inner solar system and ejects a trail of dust and gravel along its orbit. When the Earth passes through the debris, specs of comet-stuff hit the atmosphere at 140,000 mph and disintegrate in flashes of light. Meteors from this comet are called Perseids because they seem to fly out of the constellation Perseus.

Last year, this meteor shower peaked during a bright “supermoon”, so visibility was reduced. Luckily, forecasters say the show could be especially awesome this year because the Moon is nearly new when the shower peaks on Aug. 12-13.

The best place to view the event is away from city lights around midnight. Under a clear, dark sky forecasters predict meteor rates as high as 100 per hour on peak night. So, get outside, look up and enjoy the show!

If your area has poor visibility on the peak night, we’ve got you covered! We’ll be hosting a live broadcast about the meteor shower from 10 p.m. EDT Wednesday, Aug. 12, to 2 a.m. Thursday, Aug. 13. In addition to footage from our live skycam, the program will highlight the science behind the Perseids, as well as our research related to meteors and comets. Tune in on NASA TV or our UStream Channel.
